Finally, you re ready to call the DisplayMsg procedure through the deleg variable, using its Invoke method. (The OneArgSub class has inherited this method from the System.Multi castDelegate class, which in turn has inherited it from the System.Delegate class.)

void Application_Error(Object sender, EventArgs e) { ... }

You could do something useful in this event handler, such as sending an e-mail to the site administrator or writing to the Windows event log to say that the page failed to execute properly. ASP.NET provides a set of classes in the System.Net.Mail namespace for just this purpose.

This statement displays the FooBar string in the Output window. deleg.Invoke( FooBar )

void Application_Error(Object sender, EventArgs e) { // Code that runs when an unhandled error occurs var exception = Server.GetLastError(); if (exception == null) return; var mail = new MailMessage { From = new MailAddress("automated@contoso.com") }; mail.To.Add(new MailAddress("administrator@contoso.com")); mail.Subject = "Site Error at " + DateTime.Now; mail.Body = "Error Description: " + exception.Message; var server = new SmtpClient {Host = "your.smtp.server"}; server.Send(mail); // Clear the error Server.ClearError(); }

It s a long trip to just display a message, so you might wonder why delegates are so important in the .NET architecture and why you should use them. Alas, Visual Basic developers aren t accustomed to function pointers and the degree of flexibility they can introduce in a program. To give you an example, let s define another procedure that follows the OneArgSub syntax:

If the SMTP server requires authentication, you need to provide your credentials through the Credentials property of the SmtpClient class. Figure 7-3 shows the e-mail message being sent.

Display a string in a pop-up message box. Sub PopupMsg(ByVal msgText As String) MsgBox(msgText) End Sub

As Figure 7-3 shows, the exception reported mentions a generic HTTP unhandled exception. Note that GetLastError returns the real exception in the context of Page_Error, but not later in the context of Application_Error. In the application context, the exception caught is a generic HTTP exception that wraps the original exception internally. To retrieve the real exception, you must go through the InnerException property, as shown here:

In the Add New Item dialog box, click the Report template. Notice that you can launch the Report Wizard from this dialog box as well. Type a report name: Product Profitability.rdl.

Now you can decide that all the messages in your program should be displayed in mes sage boxes instead of in the Debug window, and you need only to replace the state ment that creates the delegate variable to do so:

void Application_Error(Object sender, EventArgs e) { // This is a generic HTTP failure exception var exception = Server.GetLastError(); if (exception == null) return; // Put your hands on the original exception var originalException = exception.InnerException; ... }
