So to serve a request for a page named default.aspx, the ASP.NET runtime gets or creates a reference to a class named ASP.default_aspx. Next, the HTTP runtime environment invokes the class through the methods of a well-known interface IHttpHandler. The root Page class implements this interface, which includes a couple of members: the ProcessRequest method and the Boolean IsReusable property. After the HTTP runtime has obtained an instance of the class that represents the requested resource, invoking the ProcessRequest method a public method gives birth to the process that culminates in the generation of the final response for the browser. As mentioned, the steps and events that execute and trigger out of the call to ProcessRequest are collectively known as the page life cycle. Although serving pages is the ultimate goal of the ASP.NET runtime, the way in which the resultant markup code is generated is much more sophisticated than in other platforms and involves many objects. The IIS worker process passes any incoming HTTP requests to the so-called HTTP pipeline. The HTTP pipeline is a fully extensible chain of managed objects that works according to the classic concept of a pipeline. All these objects form what is often referred to as the ASP.NET HTTP runtime environment. This ASP.NET-specific pipeline is integrated with the IIS pipeline in place for any requests when the Web application is configured to work in IIS 7 Integrated mode. Otherwise, IIS and ASP.NET use distinct pipelines an unmanaged pipeline for IIS and a managed pipeline for ASP.NET. A page request passes through a pipeline of objects that process the original HTTP payload and, at the end of the chain, produce some markup code for the browser. The entry point in this pipeline is the HttpRuntime class.

You can add an action either by using the Navigation tab of a report item s Properties dialog box or by accessing the Action property of the report item in the Properties window. Although you have a lot of freedom to choose the direction an action will take a user, you can add an action only to a textbox or an image in a report.

The ASP.NET worker process activates the HTTP pipeline in the beginning by creating a new instance of the HttpRuntime class and then calling its ProcessRequest method for each incoming request. For the sake of clarity, note that despite the name, HttpRuntime.ProcessRequest has nothing to do with the IHttpHandler interface. The HttpRuntime class contains a lot of private and internal methods and only three public static methods: Close, ProcessRequest, and UnloadAppDomain, as detailed in Table 5-2.

Creating a bitmap with a fixed degree of transparency for all its pixels requires that you pass an appropriate ImageAttributes object to the DrawImage method. Before you do so, however, you must assign a 5-by-5-pixel color matrix to the ImageAttributes object by using the SetColorMatrix method. The code that you need to write to perform this operation isn t trivial because the color matrix actually is an array of Single arrays. Here s a code example that draws an image using a transparency level equal to 0.8. (This code produces the images in the middle of Figure 17-16.)

TABLE 5-2

Dim bmp As New Bitmap( logo )

Removes all items from the ASP.NET cache, and terminates the Web application. This method should be used only when your code implements its own hosting environment. There is no need to call this method in the course of normal ASP.NET request processing. Drives all ASP.NET Web processing execution. Terminates the current ASP.NET application. The application restarts the next time a request is received for it.

Create a 5x5 matrix with the transparency value in position (4,4).
