  INTRODUCTION  First ofall I would like to thank TOPS Technologies for This article, which gives me a great opportunity to write an article for beginners on ASP.NET web development here at Tops technologies. After creating PPT on caching and view state for beginners, I have decided to Create an PPT for beginners on the ASP.NET Application Folders. However, I will be back with another PPT on rest of state management. Like my other PPT, I believe this will also give you very good idea on the Application Folders. Please give your valuable suggestions and ideas for improvement that I can incorporate into this article, as well as my future PPT. TOPSTechnologiesAsp.netcourse

  OVERVIEW - ASP.NETAPPLICATION FOLDERS • ASP.NET 2.0 uses a file-based approach. That means, all class files, resource files, data files and folders are maintained in a hierarchical structure. If we are working with ASP.NET 2.0, we can add files and folders using the Add Itemsoption. If we look at a sample application hierarchy, it will look like the following figure. • We can add as many as files and folders as we like (according to our requirements) within our solutions,and it won't be necessary to recompile them each and every time they are added. It is ASP.NET'stask to dynamically compile them when required. So, what ASP.NET 2.0 does is, it uses a predefined folder structure containing the files (classes, images, resources, etc.), to compile them dynamically and we can access those files throughout the application. ASP.NET also provides special folders to maintain files and resources. Let's see the advantages of using these folders. TOPSTechnologiesAsp.netcourse

  ADVANTAGES OF ASP.NET APPLICATIONFOLDERS • Following are the main advantages of use of ASP.NET's Application Folders • We can maintain resources (classes, images, code, databases, themes) in an organized manner, which allows us to develop and maintain sites easily • All files and folders are accessible through the application • We can add as many files as required • Files are compiled dynamically when required TOPSTechnologiesAsp.netcourse
• 5.
  DIFFERENT TYPES OFAPPLICATION FOLDER • ASP.NET treats the following folders in a special manner. They are: • App_Code • Bin • App_Data • App_Theme • App_Browser • App_WebReference • App_LocalResource • App_GlobalResource TOPSTechnologiesAsp.netcourse
• 6.
  DETAILS OF THEAPPLICATION FOLDERS • Now, to look at the use of these folders, I am going to start from App_Code. • App_Code Folder • As its name suggests, the App_Code Folder stores classes, typed data sets, etc. All the items that are stored inApp_Code are automatically accessible throughout the application. If we store any class files (like .cs or .vb) it compiles them automatically. It automatically creates type data sets from .xsd (XML schema) files, and creates XML web service proxy classes from WSDL.Let's have a look at how we can use the App_Code folder. • We can add an App_Code folder, by Solution File → right click → Add ASP.NET Folder → App_Code. The App_Codefolder is now added to your application. TOPSTechnologiesAsp.netcourse

  TOPSTechnologiesAsp.netcourse Note: Try toadd one more App_Code folder by using the same steps. Oops... the App_Code folder is no longer available there. So, ASP.NET allows you to add an App_Code folder only once.

   Now wecan add new items like classes, text and xml files into the App_Code folder and we can also add existing files there. TOPSTechnologiesAsp.netcourse
• 9.
  • Let's havea look at one example that shows how it works. Into the App_Code folder, I have added a classMyCSharpClass.cs. TOPSTechnologiesAsp.netcourse
• 10.
   In thatclass I have written a small spice of code for adding two numbers. TOPSTechnologiesAsp.netcourse
• 11.
  • Now, Tryto access this class, from any where in your application. You will see that MyCSharpClass is accessiblethroughout the application. • If we want to store different classes like .cs or .vb, then what will happen? If we kept both .cs and .vb classes in the same folder, it will give following compilation error: TOPSTechnologiesAsp.netcourse
• 12.
   We havea solution to overcome this problem. We have to create separate folders for C# and for VB or other classes. TOPSTechnologiesAsp.netcourse
• 13.
   Store classfiles separately in those folders and an configure the folder hierarchy in the web.config file. TOPSTechnologiesAsp.netcourse
• 14.
  BIN FOLDER • The Binfolder is used for keeping assemblies inside it. We can access those as a reference from anywhere of our web application. Use of Bin folder comes into the picture if we use any class library within our web application. Suppose we are creating a class library called TestLib. After building the library, we will get TestLib.dll. Now, right click on solution file → Add References → Project, select the TestLib Project, click on OK. Check the Bin folder, it will containTestLib.dll and TestLib.pdb files. TOPSTechnologiesAsp.netcourse

  APP_LOCALRESOURCE FOLDER • Local resourcesare specific to a single web page, and should be used for providing multilingual functionalityon a web page. • Local resources must be stored in the App_LocalResource subfolder of the folder containing the web page. Because you might have local resources for every page in your web application, you might have App_LocalResource subfolders in every folder. • Resource file names should be like <pageName>[.langauge].resx. Some examples of local resource files are,Mypage.aspx.ex.resx and Mypage.aspx.de.resx. Default.aspx.res x is the base resource file to use if no other resource file matches with the user's current culture. • If you want to create local resources for a page, open the design view of the page and then from Tool Menu selectGenerate Local  Resource. You will then see that a resource file is automatically created in the correspondingApp_LocalResource folder. TOPSTechnologiesAsp.netcourse

  APP_GLOBALRESOURCE FOLDER • The App_GlobalResource folder can be read from any page  or code that is anywhere in the web site. Global resources  must be stored in the App_GlobalResource folder at the root  of the application. We should use  theApp_GlobalResource folder when we need a single  resource for multiple web pages. We candefine ASP.NET  control properties by manually associating them with  resources in global resource files.You can add a global  resource file by right clicking on  the App_GlobalResource folder and clicking on Add Items.  Add .resx files as resources.

  SUMMARY  We have explained in this PPt all about the use of  application folders that are available in ASP.NET.  We hope we have described them well enough for  you to understand. There is lots more to learn, like  how to design themes and skins, and working with  resource files. We are giving some reference links  at the end, that can help you in further study.  Please read these links, at least the one on  resources, which are a very important part of  ASP.NET 2.0. In future we plan to create an PPT for  beginners on ASP.NET Resources. But not now. Thanks for reading, and please don't forget to give  your suggestions!
