Using Stored Procedures with MSSQL and ASP.NET 2.0
If you haven't used MSSQL stored procedures before with SQL Server and in your ASP.NET 2.0 pages then you need to read this article. In this article I will list down basic questions like the following :what is a stored procedure? How can I create a stored procedure? How can I use it from within my ASP.NET 2.0 web pages? And how can I return an output parameter value to my ASP.NET web page? A stored procedure is a script of SQL code that is stored in your database under a given name. The SQL code for the stored procedure may contain programming logic (using T-SQL IF and CASE statements for example) and SELECT, INSERT, UPDATE or DELETE statements as well. There are many benefits using stored procedures instead of writing pure SQL code. 1. Reduce Network Usage between WebServer and Database Server. 2. Code Reuse. 3. Faster in performance . 4.

Using HttpHandlers and HttpModules in your ASP.NET Websites
In this article I would explain about HttpModules and HttpHandlers and how to use it on your Website. Sometimes, just creating dynamic Web pages with the latest languages and databases just does not give you , the developer enough control over an application. At times, you need to be able to dig deeper and create applications that can interact with the Web Server itself. You want to be able to interact with the low level processes such as how the Web Server processes incoming and outgoing HTTP requests. Before ASP.NET, in order to get this level of control using IIS, you were forced to create ISAPI extensions or filters. This proved to be quite daunting and painful task for many developers because creating ISAPI extensions and filters required knowledge of C/C++ and knowledge of how to create native Win32 DLLs. Thankfully, in .NET world, creating these types of low level applications is really no more difficult than most other tasks you would normally perform.

Encrypting your ViewState in ASP.NET 2.0
In the previous release of ASP.NET, the page developer could turn encryption on and off at the application level through a config setting. When validation was set to 3DES, ViewState was encrypted before being rendered in the page. To reduce the chance of someone intercepting the information stored in the ViewState, it is good design to encrypt the ViewState. You could do this in previous releases of ASP.NET, but the support for encryption has been improved in ASP.NET 2.0, allowing you to set this on a page-by-page basis.

Master Pages is great new enhancements in ASP.NET 2.0 and if you haven't heard or use Master Pages, then you might reconsider of using this across all your existing websites. It will save you lots of times in maintaining and editing your websites source code. In old classic ASP, we do not have this features yet. Master Pages are an easy way to provide a template that can be used by any number of ASP.NET pages in your application. In working with Master Pages, you create a master file that is the template referenced by a subpage or content page. Master Pages use .master file extension whereas content pages use .aspx file extension. With MasterPages you can achieve true separation between the markup to lay out your pages and the actual content-specific markup. This makes it easy to apply a consistent look and feel to all pages in a site and makes it a breeze to update the site-wide style.
