Use Ajax For Cascading Dropdown List

<div><br/> <p><strong>Cascading dropdown with Asp.Net AJAX Toolkit</strong></p><p>Cascading dropdown can be programmed in the ASP.net in various ways. However I am planning to design my application in a highly performance based approach. For reading data web server to client I am planning to use Web Service. So the data transfer between server and client is very minimal without the bulky HTTP response with lots of HTML tags. By this you can feel the cascading very fast.</p><p>Since this article requires Ajax Control kit. It needs to be downloaded separately.</p><p>Once downloaded, create a new website and select the DEFAULT.ASPX and then switch to design mode in the Web Form</p><p><strong>In Web Form</strong></p><p>While in design mode, open the tool box and right click and choose items. In the "Choose Toolbox Item" choose the downloaded AjaxControlToolKit.dll.</p><p>Add Cascading Dropdown to the Web form from the tool box.</p><p>Add a web service named NorthwindDataService.asmx</p><p><strong>In Web Service</strong></p><p>import Ajax Control Toolkit</p><p>Add a new function named as Get Categories with the following parameters</p><p><em>CascadingDropDownNameValue:</em> Ajax control kit requires this object back for loading data [name should be kept as it is]</p><p><em>Category: </em>The category for filtering data [name should be kept as it is]</p><p>Next step is to get data from DB</p><p>import System.Data using Imports System.Data in the top</p><p>import System.Data.SqlClient also</p><p><strong>Now get a Data Reader to fill up the CascadingDropDownNameValue list.</strong></p><p>Now its time to fill up the Cascading Dropdown control with the web service and web method we created just now.</p><p><strong>Fill up the following</strong></p><p>ServicePath="NorthwindDataService.asmx"</p><p>ServiceMethod="GetCategories"</p><p>Category="CategoryName"</p><p>If you are running the website now, the first dropdown should be loaded with data now. If you are getting any errors like error 500 or method error 12031, The chances are there are few lines might be missed out</p><p>After this change, start running the website. It should compile and run. If you select the first dropdown it should return the list of categories. If you are not getting any output you may try running the web service in browser by 'set as start page' on the web service. The logic is to make sure the web service is working as expected and returning the list of categories</p><p>For the second drop down the only difference you are going to do is, passing a parameter to filter the data based on the first parameter.</p><p><b>To get the parameter from the selected item of the first DropDownList</b> Dim Param As StringDictionary</p><p>Param = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues)</p><p>Then the <i>Param Dictionary</i> will contain the data we need. We can easily fetch the value from the name value pair like Param ("CategoryName"). Use that in the select query to fetch filtered record</p><p>(For complete source code please refer <a href="http://www.vbknowledgebase.com/?Id=104&Desc=JavaScript-Ajax-Cascading-Dropdown" rel="nofollow" target="_new">Cascading DropDown</a> )</p> </div>

5 Reasons Why Some Developers Prefer Developing ASP Dot NET Applications

<div><br/> <p>Comparing two distinctly different programming languages or even two closely associated languages is definitely an exercise in futility. The reasons are simple, why compare French to English or PHP to Ruby, as people differ in their tastes, so do their choices too. In view of this, instead of focusing why X is superior to Y, I will try and focus on why some developers are more comfortable using ASP.NET as compared to competing platforms. That said, the fact that any platform continues to exist and is used by people in the field of IT, means it has at least some features, which cannot be availed using competing services. Following are the leading reasons why some developers choose to use ASP.NET for application development:</p><p>HTML5 Support and Web API</p><p>The new versions of ASP.NET from version 4.5 onwards provide developers with enhanced support for various form types specific to HTML5 such as color, search, date pickers, range, number, URL etc. Earlier many of these forms were created / designed separately prior to being integrated into an application. This support generates substantial time savings for the developer and by extension the software development company. The enhanced support is extended to the availability of Web API along with the standard ASP.NET Web Forms and ASP.NET MVC 4 package. At the very least, the Web API aids developers in simply building Web-based services/applications, while users find it easier to use online resources, while using the applications.</p><p>Security Provided By HTML5 WebSockets and OpenID Support</p><p>From version 4.5 onwards, developers can access advanced security features including HTML5 WebSockets. By using WebSockets, developers can ensure duplex communication between the web server and the client's browser. It is also possible to leverage the feature, while designing Web applications. However, availability of Visual Studio 11 is mandatory to avail this specific functionality while designing ASP.NET applications. Additional security is also available through OpenID support, which can be used with OAuth Login suitable for various.NET applications.</p><p>Asynchronous Programming Support and the New GridView Control</p><p>Recently introduced versions of.NET features support for asynchronous programming, which allows developers to read as well as write HTTP queries and requests without using OS threads. GridView Control has been a key tool of ASP.NET since the first versions were introduced decades back. In recently years, this tool has been substantially improved and the GridView Control featured in version 4.5 allows developers to easily perform tasks such as efficient sorting and paging of large data sets.</p><p>Unique Model Binding Properties and Value Providers</p><p>New versions of the framework feature unique model binding properties, which allow developers to isolate specific web forms from the model and/or binding them according to the user's requirements. This feature aids the development of Webforms independently from the model as well as unit testing each form separately. This facility reduces the chances of even small errors creeping into the final application and generates significant saving of both time and money for the software development company. The new-age Value Providers featured in recent.NET versions helps developers easily filter large data sets by using commands such as control value, cookie, session, querystring etc. Moreover, developers are free to develop their own Value Providers to enhance the filtering procedure.</p><p>Bundling and Minification Operations</p><p>This is one of the relatively new features in.NET 4.5, which is designed to minimize and bundle the size of style sheets and scripts utilized while developing an application. This feature improves the overall efficacy of the application by ensuring that the codes are easy to read, which helps minimize as well as resolves coding errors. The features are easily noticeable in a new project by viewing the coding of the Global.asax file. The factors discussed here barely scratch of surface, but hopefully they would help you understand why ASP.NET continues to dominate such a competitive market.</p> </div>

10 Mistakes Every Net Developer Would Regret

<div><br/> <p>Admit it! We all make mistakes. None of our codes starts working at strike one. We make typos, forget signing off or, as it happens with most of us, overlook the testing phase, especially when it comes to ASP.net development. To err is human. So, making mistakes is just another human phenomenon. What counts is how you tackle your errors and how you devise ways to avoid them in the ventures to come. Here's a compilation of some of the most common testing mistakes that developers often commit while catering to outsource .Net development needs. Let's take a look.</p><p><strong>XSS Security Issues:</strong> The look and feel of your UI and of course, its maintenance lies in your hands. Ensure that all user-input fields are well-customized so that no JavaScript or HTML that a user enters can rummage your web page.</p><p><strong>Universal Localization:</strong> As a usual norm, as you begin developing a new feature, you keep all the text in hard code as there are probabilities of certain changes during the course of development. As soon as the project team approves the feature, you localize the text. However, at times you tend to forget localizations of the entire text. You remember to hard code, but when it comes to localization you tend to sign off without doing the same. Probably this checklist reminds us to localize before we sign off the next time.</p><p><strong>.Net Behaves Well with IE 6 and 7 and Firefox:</strong> Test leads often report of cross-browser compatibility issues that crop up from time to time. Most of these issues usually encompass small twigs like usual IE 6 issues or minor problems relating to positioning of elements. We are dedicatedly focusing on IE version 6 and 7 and Mozilla Firefox for two reasons. Firstly, if your web page works well in these three browsers, it will function well on Opera and Safari as well. Secondly, over 98% of the visitors access your site through these browsers.</p><p><strong>Reuse Code as and when required:</strong> This law is applicable across all programming platforms and ASP.Net is no exception. Separate server and user-control elements enable specialization of code so that it can be used at other places as well.</p><p><strong>Commenting on the Code:</strong> There are no two-ways to this. Always document your code well and comment upon the right places, so that it is easier for other developers to pick up from where you left.</p><p><strong>Extended Text doesn't Mean Broken Design:</strong> As a matter of fact, names usually don't extend beyond 50 characters, but what if some user inputs a name containing 300 or even more characters. Obviously, in that case the UI will be disrupted. In this case you have two options- either codes your interface to accept long text inputs or put a limit on the length of text users can input.</p><p><strong>Write Units When Possible:</strong> Unit testing for your website can be a tedious job especially if you are not using ASP.Net MVC framework for the same. However, pulling the code-behind logic into different components that can be placed in the library can enable you to test the units. Instead of dealing with HttpHandlers using .ashx files, placing them in separate libraries is a good option.</p><p><strong>Peer Verification before Testing:</strong> Before signing off any newly added feature and sending it across to the test team, you usually pass it through peer verification. As the name suggests, in peer verification, one of your colleagues tests the application feature you have just developed and tries to find flaws in it. This allows you to identify errors easily and also simplifies the process for the testing team. When schedules are really tight, we often forget to ask for peer verification and it definitely shows at the end.</p><p><strong>Expected functioning of Enter-key:</strong> When you are using webforms in ASP.Net, the enter-key often starts functioning weirdly. In this case, you can either set default buttons on the Panel webcontrol or from code-behind.</p><p><strong>Sign Off by Product Owner:</strong> By default, the ownership of a product feature lies with the product team. Developers also have a share in ownership but that is only until the implementation level. Often when you have too much to handle, you forget to get a sign off from product owner. If the owner doesn't sign off your work it means you haven't completed it, even if you have already marked it as done. This is frustrating and can extend deadlines.</p><p>The aforementioned mistakes are common and can be made by any developer. If you are an Asp.net developer, these mistakes should be taken care of in the next development venture. If you are a business owner and looking to hire .net developers, then ensure that your developers take care of the same while developing your web application.</p> </div>

Active Server Pages Maintenance

<div><br/> <p>ASP maintenance is a technical term for maintaining Active Server Pages. If you are not familiar with ASP it is Microsoft's first server side script engine. It was created to include material added to existing web entities. It has been supersede by ASP net but, it is still a viable option and much easier to maintain than ASP net. ASP net has over taken the classic system. Classic ASP maintenance consists of many functions and this discusses a few of them.</p><p>ASP Net is the rave but Classic ASP provides you with the same working relationships. Check Box, Check Box List, Data List, Data Table, Drop Down, Data Repeater, Generic HTML, Label, Text Box, Radio Button List are just some of its great features. The Classic ASP has the benefit of being an event driven model with code that is easier to discern, more reliable and faster. Should you decide to move from the classic system to the newer ASP net, transferring is made very simple.</p><p>Since there are so many web pages out there that still require maintenance of this relationship, you will find the ASP Classic superb for the job. You get screen shots that allow you access to samples lists with check box examples. It is as simple as checking the correct answer in appropriate boxes. This is true for the functioning of data grids, data lists, drill downs, page data binds, tab strip control, text box and composite user controls. There is also the same set up for tracking output and tracing cells.</p><p>Using the required code is also simple. You will use the WebControl.asp file with references to each server control. Each control has its own ASP file. Once your references have been created you are only required to write code for each event that you want to take place. Your page form will be handled by the Framework. You simply have to include form start and end asp when you have to code the form tags. It governs all of the necessary hidden fields. The final thing that you will have to do is include the web control.asp. It is the one function that makes sure everything you have created is executed according to your desire. It is applied before rendering control. There will be a number of examples expressing the function.</p><p>If you are into developing software or maybe you are a business proprietor interested in Classic ASP maintenance, everything that you will need to know can be found right here. You will be able to distribute and manage your data and your work flow from this simple delivery mechanism. This is where you want to bring you business. It is a process that is made simple for those who find the whole idea complex. ASP maintenance will give you everything you are looking for in software development plus allow you to operate in a state that will allow for smooth, no trouble transfers.</p><p>ASP maintenance is a term for maintaining Active Server Pages. ASP Net is the rave but Classic ASP provides you with the same working relationship. You will find Classic ASP maintenance superb for the job.

Introduction to C++ Programming

<div><br/> <p>This article gives you an introduction to C++ Programming from ground level. <br/><br>This article won't teach you all the fundas of C++ programming rather it gives <br/><br>you the base to learn C++ programming, remember that for further learning, the <br/><br>base should be strong and this is what this article tries to do. It would let <br/><br>you know many fundas which will help you in further learning of the the language. <br/><br>C++ was developed in 1980s in the Bell Laboratories by Bjarne Stroustrup as an <br/><br>object oriented programming language. This language is considered by many as an <br/><br>extension of the programming language C. The extension of programming language <br/><br>C to create C++ is obtained by adding classes to C. This is why C++ was initially <br/><br>called "C with Classes". The C++ programming language derives its <br/><br>name from the increment operator used in C, which increments the value of a variable. <br/><br>The symbolic name of C++ rightly indicates that this language is enhanced version <br/><br>of C.</p><p><strong>Features <br/><br>of C++ Programming Language:-</strong> <br/><br><ol><br/><li> C++ programming language is highly flexible, versatile and very powerful <br/> programming language for developing any software specially the system software <br/> namely operating system, compilers etc. </li><br/> <li> C++ is most ideally suited language for development of reusable programs, <br/> which is very important to keep the production cost minimum. </li><br/></ol><strong>Comparison of C++ Programming Language</strong></p><p>Let us see how C++ compares <br/><br>with other programming languages. All the programming languages can be divided <br/><br>into two categories:- <br/><br><ol><br/><li> Problem oriented languages or High-level languages: These languages have <br/> been designed to give a better programming efficiency, i.e. faster program <br/> development. Examples of languages falling in this category are FORTRAN, BASIC <br/> etc. </li><br/> <li> Machine oriented languages or Low-level programming languages. These languages <br/> have been designed to give a better machine efficiency, i.e. faster program <br/> execution. Examples of programming languages falling in this category are <br/> Assembly Language and Machine Language. </li><br/></ol><br/>C++ stands in between these two categories. That's why it is often called <br/><br>a Middle level language, since it was designed to have both: a relatively good <br/><br>programming efficiency (as compared to Machine oriented languages) and relatively <br/><br>good machine efficiency (as compared to Problem oriented languages).</p><p><strong><u>Getting Started with C++ Programming</u></strong></p><p>Communicating with <br/><br>a computer involves speaking the language the computer understands, which immediately <br/><br>rules out English as the language of communication with computer. However, there <br/><br>is a close analogy between learning English language and learning C++ language. <br/><br>The classical method of learning English is to first learn the alphabets or characters <br/><br>used in the language, then learn to combine these alphabets to form sentences <br/><br>and sentences are combined to form paragraphs. Learning C++ programming is similar <br/><br>and much easier.</p><p>Therefore, instead of straight-away learning how to write programs, we must first <br/><br>know what alphabets, numbers and special symbols are used in C++, then how using <br/><br>these, constants, variables and keywords are constructed, and finally how are <br/><br>all these combined to form an instruction. A group of instruction would be combined <br/><br>later on to form a program. <strong>Character Set</strong>Character set is a set <br/><br>of valid characters that the language can recognize. A character represents any <br/><br>letter, digit or any other sign. C++ has the following character set:</p><p>Letters A-Z, a-z</p><p>Digits 0-9</p><p>Special Symbols space + - * / ' " ( )[ ] etc.</p><p>White Spaces blank space, horizontal tab, carriage return, newline etc.</p><p>Other Characters, C++ can process any of the 256 ASCII characters as data or as <br/><br>literals.</p><p>The alphabets, numbers and special symbols when properly combined form constants, <br/><br>variables and keywords. Let us see what these are:- <br/><br><ul><br/><li> <strong>Constants:</strong> Constants are data items that never change <br/> their value during a program run. C++ programming language allows several <br/> kinds of constants. </li><br/> <li> <strong>Variables:</strong> Variables are quantities that may vary during <br/> program execution. Variable names are names given to locations in the memory <br/> of computer where the value is stored. </li><br/> <li> <strong>Keywords:</strong> These are the words that convey a special meaning <br/> to the language compiler. Keywords are the words whose meaning has already <br/> been explained to the C++ compiler. The keywords cannot be used as variable <br/> names because if we do so we are trying to assign a new meaning to the keyword, <br/> which is not allowed by the computer. Examples of keywords are if, void, for, <br/> switch etc. </li><br/></ul><strong>Data Types in C++</strong></p><p>Data types are means to identify the types of <br/><br>data and the associated operations to handle it. In C++ data types are broadly <br/><br>of two types:- <br/><br><ol><br/><li> <strong>Fundamental Data Types:</strong> These are predefined to the C++ <br/> language itself. there are at least five fundamental data types. <br/> <ul><br/><li> char- represents that the declared variable of this type can store <br/> characters </li><br/> <li> int- represents integers </li><br/> <li> float- represents floating point numbers </li><br/> <li> void- represents valueless data </li><br/> </ul><br/></li><br/> <li> <strong>Derived Data Types:</strong> These are constructed from the fundamental <br/> types. I will not give you the details here because this is a bit high-level.</li><br/></ol><strong>Instructions in C++ Programming Language</strong></p><p>Now that we seen the <br/><br>different types of constants, variables and keywords the next logical step is <br/><br>to learn how they are combined to form instructions. <br/><br><ul><br/><li> <strong>Type declaration instructions:</strong> to declare the type of <br/> variables used in the program.<br/><br/> Eg:- <strong>int num;</strong><br/><br/> Here a variable num is declared of type int(eger). </li><br/> <li> <strong>Input /Output instructions:</strong> to perform the function supplying <br/> input data to a program and obtaining the output results from it.<br/><br/> Eg:-<br/><br/> <strong>cin>>a;<br/><br/> cout<br/><br/> In the first line input is taken from the keyboard by the function cin and <br/> is assigned to a pre-declared variable a. In the second line 'Hello' <br/> is printed using the function cout. </strong><br/></li><br/> <li> <strong>Arithmetic instructions:</strong> to perform arithmetic operation <br/> between constants and variables.<br/><br/> Eg:- <strong>c=a+b;</strong><br/><br/> Here c is assigned a value which is the sum of the variables a and b. </li><br/> <li> <strong>Control instructions:</strong> to control the sequence of execution <br/> of various statements in a C++ program.<br/><br/> Eg:- <strong>if (a>b) func1();</strong><br/><br/> Here it is checked whether a is greater than b, if it is, then program execution <br/> goes to a user defined function 'func1'. </li><br/></ul><strong><u>The first C++ Program</u></strong></p><p>Armed with the knowledge about the <br/><br>types of variables, constants, keywords etc. we would write down our first C++ <br/><br>program.</p><p>Each instruction in a C++ program would comprise of a series of statements. These <br/><br>statements must appear in the same order in which we want them to be executed.</p><p>The following rules are applicable to all C++ programs no matter ho long or complicated <br/><br>they are</p><p><ul><br/><li> Blank spaces may be inserted between two words to increase readability <br/> of the statements. However, no blank spaces are allowed within a variable, <br/> constant or keyword. </li><br/> <li> Usually all statements are entered in small case letters. </li><br/> <li> C++ has no specific rules for the position at which a statement is to be <br/> written. That's why it is often called free-form language. </li><br/> <li> Any C++ statement always ends with a semicolon (;). </li><br/></ul><br/>Now, let us have a look at a program which calculates the sum of two numbers given <br/><br>by the user. <br/><br><blockquote></p><p><strong>//To calculate the sum of two given numbers</p><p>#include<iostream></p><p>main()</p><p>{</p><p>int num1; //declares a variable num1 of type int(etger)</p><p>int num2; //declares a variable num2 of type int(etger)</p><p>int sum; //declares a variable sum of type int(etger)</p><p>cin>>num1; //takes input and stores to the var num1</p><p>cin>>num2; //takes input and stores to the var num2</p><p>sum= num1+num2; //adds vars num1 & num2</p><p>cout </iostream></strong><br></blockquote><br/><br><strong>A few useful tips:-</strong> <br/><br><ul><br/><li> Any C++ program is nothing but a combination of functions, main() is one <br/> such function which is always there in a C++ program in one form or the other. <br/> Empty parentheses are necessary after main. </li><br/> <li> The set of statements belonging to a function is enclosed within a pair <br/> of braces<br/><br/> Ex.<br/><br/> main()<br/><br/> {<br/><br/> statement1;<br/><br/> statement2;<br/><br/> statement3;<br/><br/> statement4;<br/><br/> } </li><br/> <li> Any variable is declared before using it. </li><br/> <li> Any C++ statement should always end with a semicolon. </li><br/> <li> iostream.h is the file needed to use the functions cin and cout, which <br/> is included in the program with the include keyword. </li><br/></ul><strong><u>Summary</u></strong></p><p>After going through the article you have got an <br/><br>introduction to C++ Programming, you now know what C++ is and how it is used. <br/><br>You now know the C++ language and have learnt some of the most fundamental parts <br/><br>of C++. you have learnt how to declare variables and how to use them in arithmetic <br/><br>operations. In one sentence you have got an introduction to C++ programming which <br/><br>will help you in further learning of the language.</p> </div>

An Overview of Entity Framework in ASP Net and Its Use in the Industry

<div><br/> <p>The Entity Framework (EF) is a part of the .NET Framework by Microsoft and works as an open source ORM (Object Relational Mapping) for the same. The framework is written using the C# language on the .NET Platform itself and has an Apache License. The first stable release for the EF was done in August 2008 and the last stable release dates back to March 2015. The framework primarily works to assist in the development of software applications that are data oriented. It does that by eliminating the need to write the various data access codes by giving automated mechanism to access and store data inside a database. This allows the developers to focus more on the business problems and build the logics for these problems rather than having to work with the database coding.</p><p><strong>What exactly does Entity Framework do?</strong></p><p>The EF allows the developers to interact easily with the data as they work on the applications by using a series of tools that automate the database handling on all the applications built using the .NET Framework. The changes in the objects are automatically updated to the database as they're used in the applications developed using the same. Also, the database connectivity is taken care of by the framework itself that eliminates the writing of long codes by the developers. The framework also allows more freedom in choosing the way data is presented without the need to spend long hours into working with the storage and access codes. Furthermore, the framework allows you to work with your Visual Studio based apps and is suited more the interactive kind of applications. In short, the entity framework allows an individual or a Web Development Company to work on the business model without the need to worry about database coding.</p><p><strong>Advantages of using Entity Framework:</strong></p><p>There are various advantages of using the Entity Framework while developing the web applications on the .NET Framework. Some of the prominent benefits of using this framework are listed below:</p><p><ul><br/><li><br/>The overall database performance is enhanced on using the entity framework as you'll be working with objects and not with the database tables. Performing actions like select, insert, update, delete and so on will work faster as compared to the traditional methods.</li><br/><li><br/>You will not have to write any SQL yourself as most of the Create, Read, Update and Delete (CRUD) operations are going to be performed by the framework itself. As mentioned earlier, any changes to the object is detected by the framework. When the changes are saved, the framework generates an automated insert/delete/update statement that ensures the change to be reflected in the database as well.</li><br/><li><br/>The Entity Framework makes it convenient for the programmer to add new database support like Oracle as it is not only restricted to using the Microsoft SQL Server only.</li><br/><li><br/>The framework provides the developer with the ability to have some inherent relations between the created entities.</li><br/><li><br/>The framework makes it convenient to manage 'one to one', 'one to many' and 'many to many' type of relations in a database.</li><br/></ul><br/><strong>Entity Framework: An Important industry tool</strong></p><p>When it comes to creating applications using entity framework, you will surely find a Professional Web Development Company that uses this technology for developing web based apps. Due to inherent capabilities and advantages of this framework, working with .NET becomes easier. Such ease is welcome in the product driven web applications and you will find web development services UAE, US, UK, India and even Australia using this technology for that very reason. So, if you're a newbie to the development scene and want to start working with entity framework, then you can go through the guides available across the web and get started. However, if you're a businessman thinking of getting your own web app made, then you know the perks offered by this framework and should look for an Open Source Development Company that can create custom web application for you using this very framework.</p> </div>

Presentation Patterns ASP NET MVC

<div><br/> <p>The Model-View-Controller (MVC) pattern is a pattern used for separating presentation details from business domain details. The Model in the pattern is the business model/domain and the business logic of the system. The View is the presentation of the data and the user interface of the system. The View (V) generally speaks to the Model via the Controller, which is usually responsible for gathering data from the V, and interacting with or updating the Model, as well as updating the V (either the V can be explicitly notified that it must be updated by the controller, or will be notified of changes from the Model by following an Observer pattern).</p><p>There are different variations to the classic MVC pattern, namely Model2, Model-View-Presenter (MVP), and PresentationModel (also known as Model-View-View-Model or just ViewModel).</p><p>PresentationModel is a pattern used in desktop Windows WPF applications and so will not be discussed here.Although it is gaining traction as a pattern for Silverlight Rich Internet Applications (RIA's).</p><p>The two patterns for web development are Model2 and MVP.</p><p>In the classic MVC pattern, the User interacts with the View, the View notifies the Controller of the action, and the Controller updates the Model. The Model then updates the View via an Observer pattern - the View listens for notifications from the Model, and when the Model is changed, it notifies the View of the changes, allowing the View to update itself.</p><p>In the MVP pattern, the Presenter can be thought of as the Controller in classic MVC, however MVP is different to the classic MVC pattern in that it completely separates the View from the Model: the View can only speak to the Presenter, and the Model can only speak to the Presenter as well. There are two variations of the MVP pattern: Supervising Controller and Passive View. In Passive View, the View only ever receives notifications from the Presenter: it is the Presenter's responsibility to retrieve details from and send details to the View. In Supervising Controller, this responsibility isn't as strict, in that the View may notify the Presenter of any changes to itself (usually through Data Binding).</p><p>Model2 is similar to the MVP pattern in that the View and Model are completely separate and only communicate through a Controller, however it also has the concept of a Front Controller. The Front Controller is what the View speaks to in Model2 - when a User interacts with a View, the View will interact with the Front Controller, which will determine which View the request came from, and to which Controller the request must be dispatched to fulfill the request, switching to different views if necessary.</p> </div>

Web Site Technology - Consider Your Options

<div><br/> <p>Not long ago, a friend of mine sent me an email asking for my opinion on whether a site he was developing should be done using Wordpress, LAMP, or ASP.NET. I've used all of those, but have always been so focused on the details and learning them that I never really thought about the great question of "What technology should be used for a given site?". That is such a good question that I decided to put my thoughts on paper and help provide some education to others.</p><p>Some people don't have the skills and ability to actually be able to choose the most appropriate technology. They know one thing and that is going to have to be made to work in all cases. That's not necessarily bad, but it's nice to be able to switch between technologies based on the type of site. The important thing to realize in web site development is that one technology does not fit all.</p><p><u><b>Wordpress</b></u></p><p>I have several web sites currently running Wordpress. I originally thought of Wordpress as just a blogging platform. While that is certainly its main use and what it is optimized for, you can definitely use it to create a more "traditional" looking web site. It is very configurable and there are tons of custom plug-ins available that can allow you to add RSS feeds, SEO tags, voting, etc. Since Wordpress is developed using PHP and MySQL, it is also possible to create your own plugins and customize your site template. Oh, and that's the other incredibly awesome thing about Wordpress -- the templates! There are literally thousands of free Wordpress templates available for download. If you can't find one that fits the theme of your site than you aren't looking hard enough.</p><p>Another nice thing about Wordpress is that you can easily find web hosting providers that support Wordpress. In most cases, you can click an install link and have Wordpress properly installed on your site in a few seconds. Then you go to the Wordpress admin console and configure your site. It is all very easy. You can upload multiple templates and easily switch between them. It is also easy to make minor changes to the templates (like changing tag lines, colors, etc.).</p><p>The other benefit of Wordpress is that it is a blogging platform and the search engines love blogs. You can configure your Wordpress install to automatically ping one or more blogging services whenever you add a new post or page. That way they know your site has changed and they should come index your site again. If you want your site to be found then using Wordpress as the underlying engine is a good option.</p><p><u><b>LAMP</b></u></p><p>In case you don't know, LAMP stands for Linux-Apache-MySQL-PHP, which is a very common and powerful set of technology components used for building web sites (and did I mention completely Open Source and free!). If you want complete control over your web site, then LAMP is a good option. There are plenty of examples, free scripts, etc. available on the web site to help you get started. There are also plenty of free editors and tools to help you along. The downside of LAMP is that it is hard for you to create your own development "environment". Since most of us run some flavor of Windows as our desktop operating system, we would need to use something like VMWare or Virtual PC to create a virtual machine running Linux. The next challenge is getting all of the components properly installed. While the installers for the LAMP components have definitely improved, they still don't compare to the ease of installing a Windows-based application. The next challenge with LAMP is debugging. It would be nice if we all wrote perfect code, but the reality is you need the ability to debug. There are PHP debuggers available. A good one is going to cost you some money though.</p><p>One of the best things about LAMP is that there are TONS of web hosting providers out there for you to pick from. The reason is quite simple -- LAMP is completely open source, so it there is very little cost for the hosting company to bear. That means more margin for them!</p><p><u><b>ASP.NET</b></u></p><p>Microsoft's contribution to web site development is ASP.NET. You can use any .NET language (C#, VB.NET, Python.NET, etc.) to develop an ASP.NET based site. In my opinion, the best thing about ASP.NET is the fact you can use Microsoft Visual Studio for you development tool. Visual Studio is the best tool out there. Yes, it costs money, but you definitely get what you pay for. The other nice thing about ASP.NET is that you can easily develop on your Windows-based desktop or laptop.</p><p>It is harder to find a good ASP.NET hosting provider. Believe me, I've looked! And I've used several different ones. The ASP.NET providers lag behind the LAMP providers in terms of what they offer. You also need to be careful and really understand what the provider means by things like "host unlimited # of domains". In many cases they just mean you can have an unlimited # of domains point to your single web site. That probably isn't what you want.</p><p>I mentioned the use of Visual Studio before. That tool is awesome and makes development SOOOO much easier. I did quite a bit of development using LAMP and got some sites up and running. I used Eclipse with a PHP plug-in and it worked pretty good. I didn't have Apache running or Linux, so couldn't really debug but I still managed. When it came time to create a more advanced web site, however, I quickly decided to switch over to ASP.NET and use Visual Studio. Debugging was a snap and the coding was made much easier thanks to Intellisense and Visual Studio's ability to "import" web services and make them easier for me to call from my code.</p><p><u><b>Making the Right Choice</b></u></p><p>Each of the technology options has pros and cons. If you want to get a site up quickly and it will be displaying basic information (text, images, video) then Wordpress is a great option. If you want a more advanced web site but don't want to spend much money on development tools, then LAMP is the best choice. Finally, if you already have Visual Studio or know .NET programming, then ASP.NET is a good option. If you're really lucky and can know all three then you can use the right tool for the job no matter what.</p> </div>

ASP Dot NET Hosting - Picking the Right ASP Dot NET Hosting Provider

<div><br/> <p>Programmers love to code ASP.NET applications, deployment, however, can be a frustrating experience. In fact, getting ASP.NET hosting right is something of an art, and few hosting providers really manage to nail it.</p><p>When searching for a great ASP.NET hosting company, you must always try to get hold of a company that offers you the latest version of ASP.NET, IIS, and Windows Server. They must additionally carry SQL Server, because this is what most.NET developers use. If you adopt Access, then search for its support. Realize though, that Access has its limits when it comes to multiple connections (seeing that a file-based db).</p><p>Other stuff to take into account are whether or not you're able to get adequate CPU and RAM resources, if you have full trusted application support, and whether backups, monitoring, and security are all taken care of by the hosting provider for you. Overall, it would be silly to try to manage the hardware yourself. Whether you opt for shared, VPS (Virtual Private Server) or dedicated ASP.NET hosting, favor managed solutions.</p><p>The pairing of ASP.NET and SQL Server can be demanding if your application receives enough visits, and as such it's wise to realize that shared hosting is best viewed as a last resort (and then only if it's not within your resources to afford a VPS or dedicated ASP.NET service solution).</p><p>If you'd like to spend very little, try VPS hosting solutions, as they tend to provide a good compromise between the type of resources that are made available to each customer and cost. A good managed VPS can cost you as little as $40 per month, which isn't all that much if you use your site for business or other serious purposes.</p><p>When choosing a company, it's a reasonable idea to study testimonials about them and go with solutions that appear to focus on ASP.NET, rather than merely nonchalantly mentioning it once on some random page. Reputable ASP.NET hosting services exist, and you should favor these over hosting companies that are only out to get your money.</p><p>But how to separate the two? The answer is easy: read trusted reviews and recommendations, particularly from fellow programmers. After a little while you'll see that it really isn't problematical to weed out the chaff from the wheat.</p> </div>

Multi Threading in C#, ASP.Net

<div><br/> <p>Multithreading is a powerful tool for creating high performance applications because they can run simultaneously on the system. Microsoft .NET gave us the facility to creating multithreaded applications. This is part one of a two-part topic. In this article we will cover the background on threading along with an example of how multiple threads can be used to improve an application's user interface. The question is this when we used threading? Simple Threads are implement when there are situations in your application in which more then one task at a time need to be completed.<br/><br>There are some cons and pros of multithreading:-</p><p>Using threads the long duration tasks in application can be processed at the background or speed can be increased but Programming and debugging is more complex when you use multithreading. Threads add overhead to the system or we can say that more thread more overhead on system In order for the operating system to track a large number of threads it is going to consume processor time. If there are too many threads then each thread may not be given enough time to execute during its time execution. In addition, each thread is scheduled for execution less frequently due to the volume and time slice committed to each thread. So use thread pool every time for multithreading. In thread pool when there is any work then use of thread in thread pool otherwise send them into thread pool back.</p><p>How to use:-</p><p>To use multithreading first of all create a delegate object and then initialized this object with our method then create a new thread object using this delegate</p> </div>

Ajax in C# ASP.Net Web Pages

<div><br/> <p>What is AJAX? AJAX stands for asynchronous JavaScript and XML, and is a technology that allows your ASP.Net web pages to work much more dynamically.</p><p>An AJAX-enabled website has three major benefits:</p><p><ul><br/><li>Less bandwidth use</li><br/> <li>More responsive</li><br/> <li>More like a desktop application</li><br/></ul></p><p>A normal ASP.Net page does a full postback whenever certain events are triggered, more specifically button Click events. What that means is the state of the whole page is sent to the server, updated, and then the whole page is returned to display to the user.</p><p>What AJAX does is allow the webpage to do a postback on small parts of the page. By creating an UpdatePanel, only the part of the page inside of it will postbacked. Thus the rest of the page can remain intact.</p><p>The obvious benefit of not having to resend the entire page is the reduced use of bandwidth. Also not having to refresh the entire page makes the ASP.Net page faster and more responsive. Thus behaving more like a desktop application.</p><p>The best part of AJAX is that it's super easy to integrate into your webpages. Simply install the Microsoft Atlas Framework and you are good to go. Just remember to add a ScriptManager on the very top of the ASP.Net page.</p><p>As you might have guessed by now, AJAX opens up the door to all kinds of custom web controls. The Atlas Framework does not come with many prebuild controls so a good place to start is with the <a href="http://vckicks.110mb.com/asp_net_ajax_controls.html" rel="nofollow" target="_new">Ajax Control Toolkit</a>.</p> </div>

Grails + AngularJS = Better JavaScript

<div><br/> <p>In addition to being the most popular client-side programming language, JavaScript is also currently being used along with HTML5 and CSS3 for development of responsive websites and web-based mobile apps. But the developers still need to use various JavaScript libraries and frameworks to build quality web applications rapidly. Many programmers prefer combining JavaScript libraries with other web frameworks to enhance the web application's functionality and performance. A number of reports have highlighted that many web developers nowadays prefer using AngularJS and Grails framework together.</p><p>Grails Framework</p><p>Grails is a web application framework which is designed for the Java platform but uses Groovy programming language. It aims to make programmers more productive by supporting software development paradigms like Convention over Configuration (CoC). At the same time, Grails also comes with features like integrated ORM, support for NoSQL, and dependency injection powered by Spring. The users can further extend the framework by using a number of built-in plug-ins additionally. Grails further allow programmers to work with several popular IDEs and text editors like Sublime, Eclipse and Texmate.</p><p>AngularJS</p><p>As a structural framework, Angular makes it easier for programmers to create a variety of dynamic web applications. It is used widely by developers for creating single-page websites. While using Angular, the programmers have option to use HTML as a template language. They can simply extend the syntax of HTML to express the application's components in a clear and readable format. As the framework keeps the view and data model of the application synchronized the developers are not required to manipulate the document object model (DOM) manually. Angular can also be integrated with a number of libraries. The users can further customize the framework according to their specific needs by making changes to its features.</p><p>How to Combine Grails and AngularJS?</p><p>The developers can use a specific plug-in to add AngularJS resources to the Grails application. The plug-in will add services, controllers and other resources of AngularJS to the Grails application. At the same time, it will also generate several AngularJS modules like angular-animate, angular-touch, angular-cookies, angular-messages, angular-sanitize, angular-route, angular-loader, angular-resource, and angular-aria. These modules help developers to add functionality to the Grails application without putting any extra effort.</p><p>Alternately, the developers can also combine AngularJS and Grails by converting the AngularJS code into CoffeeScript code. However, this method is recommended only for users who are familiar with CoffeeScript. They can simply use the plug-in provided by Grails to convert JavaScript code into CoffeeScript code. As CoffeeScript aims to make JavaScript code more readable, it will be easier for programmers to manipulate the code from the Grails applications.</p><p>Why Combine Grails and AngularJS?</p><p>The developers can combine AngularJS and Grails in a number of ways. So they can combine the two frameworks without any hassle. After combining the two web frameworks, they can make each to take care of certain tasks. So they can split the common task between the two frameworks to enhance the applications performance and functionality significantly.</p><p>In comparison to Grails, AngularJS is more effective in handling single-page websites. So it can handle the changes made to a single page more efficiently. So the developers can use it for handling single-page changes like DOM manipulation and client-side data binding. Likewise, AngularJS can also be used for making AJAX calls and organizing client-side <a href="http://www.mindfiresolutions.com/Offshore-Javascript-AJAX-Development-India.htm" rel="nofollow" target="_blank">JavaScript development</a> code. It will further make it easier for developers to perform client-side unit tests through the Jasmine. The developers can also take advantage of the client-side dependency injection (DI) provided by Angular JS.</p><p>On the other hand, features and functionality of the Grails can be availed to manage large-scale websites more effectively. It can be used effectively for providing RESTful services, and mapping URL for full-page transition. Grails will further help programmers to manage application concerns like client-side and server-side dependencies, command control centers, overall file layout, and packaging and building. Likewise, Grails will help users to perform unit, integration and functional testing on the server-side. They can even use Spring to manage server-side dependencies more efficiently.</p><p>On the whole, the developers can combine <a href="https://angularjs.org/" rel="nofollow" target="_blank">AngularJS</a> and Grails in a number of ways. After combing the two frameworks, they can avail their features to effectuate common client-side and server-side activities. However, they still need to divide tasks between the two frameworks based on their individual features and functionality.</p> </div>

N Tier Architecture in ASP Dot NET

<div><br/> <p>Architecture is an important feature and the very first step in the development of an application. n-Tier is the term used for multiple tier or multiple layers. n-Tier Architecture splits the solution process into different projects based on the business requirements. The main advantage of using n-Tier is that the complexity associated with the business and the process is reduced and it is easy to work with. The elements of performance, scalability and future development issues need to be considered when deciding on the architecture of the application depending on the priorities required.</p><p>The n-Tier application has three tiers or layers - they are called the presentation tier, the business tier and the data tier. Each layer interacts with the layer directly below, and has a specific function to perform. Presentation Layer is responsible for displaying user interface to either programmer or end user. Programmer uses this layer for designing purpose and to get the data back and forth. In ASP.NET it includes ASPX pages, user controls, server controls and sometimes security related classes and objects.</p><p>The Business layer works as a mediator to transfer the data from the presentation layer. In the three tier architecture the data access layer is not made to interact with the presentation layer. The architecture in ASP.NET includes using SqlClient or OleDb objects to retrieve, update and delete data from SQL Server or Access databases and passing the data retrieved to the presentation layer in a DataReader or DataSet object, or a custom collection object. The Data layer gets the data from the business layer and sends it to the database or vice versa. This layer is further divided into two sub layers Business Logic Layer (BLL) and Data Access Layer (DAL). DAL is responsible for accessing data and forwarding it to BLL. In ASP.NET it uses SqlClient or OleDb to retrieve the data and send it to BLL in the form of a DataSet or DataReader. BLL (Business Logic Layer) is responsible for preparing or processing the data retrieved and sends it to the presentation layer.</p><p>The Data layer gets the data from the business layer and sends it to the database or gets the data from the database and sends it to the business layer. In ASP .NET it is an SQL Server or Access database. It can also be Oracle, MySQL or even XML.</p><p>In an ASP.NET n-tiered architecture web pages do not make direct calls to the database. A given layer only communicates with its neighboring layers. ASP.NET Web pages should reference custom objects defined in the business object layer. These objects provide database information in a class structure.</p><p>The partitioning of ASP.NET applications into front-end, middle tier and back-end layers, the n-Tier architecture supports a more uniform, building block approach to application designs. Hardware and software for presentation, application and database functions can be scaled separately, and included more easily into complex e-Business environments.</p> </div>

Controls Available in ASP.NET

<div><br/> <p>There are number of ASP.NET controls some of these are explain bellow.</p><p>o HTML server controls:- HTML elements helps server so we can use for us in programming . HTML server controls expose an object model that maps very closely to the HTML elements that they render for so we can get HTML server control in programming.</p><p>o Web server controls:- These Controls are more features than HTML server controls because as name suggest these are on web so helps lots. Web server controls not contains only form-type controls such<br/><br>as buttons and text boxes, but also contains some special-purpose controls such as a calendar. Web server controls are more abstract than HTML server controls in that their object model does not necessarily reflect HTML syntax.</p><p>o Validation Controls:- These collect logic or we can say conditional controls that allow us to test a user input. We can simply attach a validation control to an input control and test what the user input in the input control. Validation controls are provided to allow you to check for a required field, to test against a specific value or pattern of characters, to verify that a value lies within a range, or we can also compare and also take a validation summary.</p><p>o User Controls: - These controls are helpful where we have to use that particular control at many places. We can include Web Forms user controls in other Web Forms pages that help in creating menus, toolbars, and other reusable elements.</p><p>oOther controls:- These control are likes for mobile devices. For creating the mobile application we use same framework which we use for web application, but we create Mobile Web Forms instead of Web Forms<br/><br>pages and use controls specifically designed for mobile devices.</p><p>Learn <a href="http://www.dotnetquestion.info/dot_net/interview.htm" rel="nofollow" target="_new">Interview Questions Answers</a> and face interview confidently</p> </div>

Java Hashtable

<div><br/> <p><b>Hashtable</b></p><p>A collection allows a group of objects to be treated <br/><br>as a single unit. Map is one of the core interfaces of java collection framework <br/><br>that defines operations for maintaining mappings of keys to values.</p><p>Map interface does not implement Collection <br/><br>interface, because it does not contain elements but contains entries of keys and <br/><br>their corresponding values (i.e. called mapping).</p><p>Map does not allow duplicate keys. So there is <br/><br>utmost one value that is mapped with the given key. Both key and value must be <br/><br>an Object (Primitive values must be wrapped).</p><p>Hashtable implements Map interface (As of the Java 2 <br/><br>platform v1.2, this class has been retrofitted to implement Map, so that it <br/><br>becomes a part of Java's collection framework).</p><p>Hashtables will automatically grow when you add too <br/><br>many elements.

Best Kept Secret About Displaying RSS Feeds On-Site - Javascript Vs PHP

<div><br/> <p>If you've gotten past the basics of what RSS feeds are about and how they can benefit you, then you are ready to learn one of the best-kept secrets about presenting your news feed on your website. It's not enough to simply install an orange RSS button for visitors to click, to see your feed or to fetch the feed address. To really bring benefit to your site, you should display some of the most recent items in your feed directly on your website, even if only a partial presentation of the item descriptions (aka articles).</p><p>But how? What code is used to display the news feed? After all, the feed is an XML file not suitable for direct human consumption. It needs to be translated into the HTML code that a browser understands and can present in human-readable form.</p><p>The good news is that there are websites out there that offer scripts to do that translation to human-readable text. You can locate them by doing Google search on terms like "RSS feed translation". You will learn that there are basically two kinds of scripts that are up to the job: <a name="YANDEX_1"></a><nobr><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_0"></a><span class='highlight highlight_active'> javascripts </span><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_2"></a></nobr> and PHP scripts. Think there's no big deal as to which you should use? <em>Think again.</em></p><p>In making your decision as to using a <a name="YANDEX_2"></a><nobr><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_1"></a><span class='highlight highlight_active'> javascript </span><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_3"></a></nobr> or a PHP script, keep in mind two important goals pertaining to use of your feed on site. First, search engines appreciate websites that have fresh content posted every so often. Not wholesale changes (that could actually penalize your site), but tidbits of new information, with such information being posted every few weeks. If your website offers fresh content, search engines will reward your site with higher Search Engine Results Page (SERP) placement, even though your page rank remains the same.</p><p>Second, if search engines can "see" your fresh content (in other words, if search engine spiders can crawl that content), and if that content is relevant to the theme of your website, you will be further rewarded with increased "importance" (aka page rank). That increased importance will also improve your SERP placement.</p><p>So, your opportunity is to display your news feed (say the first couple of most recent items) in a way that presents fresh content that is crawled by spiders. By simply posting a small article every few weeks, your web site will leap upwards on SERP.</p><p>Now let's take a close look at using <a name="YANDEX_3"></a><nobr><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_2"></a><span class='highlight highlight_active'> javascript </span><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_4"></a></nobr> vs PHP scripts for the feed presentation. Here's the fundamental difference between the two -- and the critical reason for choosing PHP scripts. <a name="YANDEX_4"></a><nobr><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_3"></a><span class='highlight highlight_active'> Javascripts </span><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_5"></a></nobr> are executed AFTER your webpage is presented to the browser for display to your site visitor. That means that spiders, visiting your site, <em>see the <a name="YANDEX_5"></a><nobr><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_4"></a><span class='highlight highlight_active'> javascript </span><a href="http://hghltd.yandex.net/yandbtm?fmode=inject&url=http%3A%2F%2Fezinearticles.com%2F%3FBest-Kept-Secret-About-Displaying-RSS-Feeds-On-Site---Javascript-Vs-PHP%26id%3D1405260&tld=com&lang=en&la=1459470464&tm=1462468523&text=site%3Aezinearticles.com%20javascript%20inurl%3Aid&l10n=en&mime=html&sign=b700b3366708303a696afdbbcaa08cfc&keyno=0#YANDEX_6"></a></nobr> code</em>, not the translated news feed! So, your site doesn't get credited for fresh content or the theme-relevant content of your feed.</p><p>On the other hand, PHP scripts are executed BEFORE the code is presented to your browser. PHP stands for "PHP Hypertext Pre-Processor". Note the word "<em>Pre-Processor</em>". This means that your PHP script is executed with your news feed being converted to HTML code before being presented. Spiders visiting your site will, therefore, see the result of script execution, i.e., the HTML code that is your translated news feed (having been translated from XML to HTML). And this means search engines will see your fresh and relevant content -- your news feed!</p><p>To understand and execute PHP scripts, note that website servers must support PHP. Most do, because PHP is an extremely popular language for website code generation. But if your server does not, ask your hosting organization to support PHP. They are likely to honor your request because of the improved competitive nature of their hosting service as a result.</p> </div>
