How to get list of all active HttpModules in ASP.NET?

Here is a quick tips to get the list of all active HTTPModules at runtime. We can get the list of all HttpModules from the web.config or from machine.config file. But, what we need to do if we want to get the list of all active HttpModules during runtime? Yes. We can easily get the details with the help of HttpApplication and HttpModuleCollection Class. If we quickly recall the IIS Process Request [One detailed Article], when a request reaches to worker Process from client browser, First of all Worker process is responsible to start and HttpRuntime by loading ISAPI filter. After that HttpRuntime load an HttpApplication object with the help of HttpApplicationFactory class. Each and every request should pass through the corresponding HTTPModule to reach to HTTPHandler, this list of module are configured by the HTTPApplication. Below is the code snippet by which we can get the list of active HttpModules.

//Get Application Instance from Current Content
HttpApplication httpApps = HttpContext.Current.ApplicationInstance;
//Get List of modules in module collections
HttpModuleCollection httpModuleCollections = httpApps.Modules;
Response.Write("Total Number Active HttpModule : " + httpModuleCollections.Count.ToString() + "
");
Response.Write("List of Active Modules" + "
");
foreach (string activeModule inttpModuleCollections.AllKeys)
{
Response.Write(activeModule + "
");
}

“CompressionEnabled” Session in ASP.NET 4.0

CSS Friendly Menu Control in ASP.NET 4.0

CodeProject
It is very much easier to apply CSS when we have ul,li elements as the HTML content. If we look into ASP.NET Menu Control till Version 3.5, its render as Table-TR-TD Tag. Though Table/Tr/Td is quite useful to display tabular data but sometime creates a big problem when we need to do more work with CSS. To overcome this problem we generally used CSS Friendly adapter to render the ASP.NET Control in ul/li mode.

ASP.NET 4.0 makes the things easier for web developer by providing "RenderingMode" properties. Here we can specify RenderMode of a ASP.NET Menu control. Which define the what will be the HTML Render Content Type. Bydefault mode is "List" which means control will be render as ul/li.

CodeProject
View State is one of the most important and useful client side state management mechanisms. It can store the page value at the time of post back (Sending and Receiving information from Server) of your page. ASP.NET pages provide the View State property as a built-in structure for automatically storing values between multiple requests for the same page.

we generally used “EnableViewState” Properties for both Page Level and Server Control Level to maintain the view state. Till ASP.NET 3.5 Version, Page Level view state control treat as highest priorities. Which means If we set EnableViewState= “False” in page level that will automatically derived by all the server side control. In that case if we set “EnableViewState=”True”” for any server side control will treat as false, as we have defined them “False” in Page Level.Here is one complete article on ASP.NET 2.0/3.5 View State , which may helpful for you

Which covered almost all main features of debugging in Visual Studio 2010 like Basic of Breakpoints,  breakpoint labeling, data tips, multithreaded debugging, and parallel debugging and IntelliTrace debugging. You can read the complete article from My Blog or from CodeProject.

While preparing the article I had created one small video on IntelliTrace Debugging which will show you the demo of using IntelliTrace Debugging.  Hope you will enjoy this video.

Mastering in Visual Studio 2010 Debugging

Visual Studio IDE gives us a lot of tools to debug our application. Sometimes debugging activity takes a very long time to identify the root cause. But VS IDE provides a lot of handy tools which help to debug code in a better way. Debugger features include error listing, adding breakpoints, visualize the program flow, control the flow of execution, data tips, watch variables and many more. Many of them are very common for many developers and many are not. In this article, I have discussed all the important features of VS IDE for debugging like Breakpoint, labeling and saving breakpoints, putting conditions and filter on breakpoints, DataTips, Watch windows, Multithreaded debugging, Thread window, overview of parallel debugging and overview of IntelliTrace Debugging
