SUMMARY
=======

This article describes how to build a Microsoft Internet Information Server
(IIS) application in Visual Basic.

MORE INFORMATION
================

Steps to Build a Simple IIS Application
---------------------------------------

1. Start Visual Basic. In the New Project dialog box, select IIS Application,
  and then click Open.

2. In the Project Explorer, select Project1 (Project1). In the Properties
  window, modify the Name property to give your project a name. On the File
  menu, click Save Project.

  NOTE: You cannot continue to the next steps to import an HTML file until you
  save the project.

3. In the Project Explorer, click to expand the Designers folder. Right-click
  WebClass1 (WebClass1.Dsr), and click View Object on the shortcut menu. The
  WebClass designer window appears.

4. Right-click the HTML Template WebItems folder, and click Add HTML Template to
  add an HTML file to your project. By default, this HTML Template WebItem is
  called Template1 in the WebClass designer window.

  NOTE: If the xxx.htm file that you select is in your project's working
  directory, the WebClass designer makes a copy of the xxx.htm file (named
  xxx1.htm) and places it in the working directory of your project. xxx1.htm is
  the HTML file that the WebClass designer makes changes to. If the xxx.htm
  file that you select is not in the working directory of your project, the
  WebClass designer places a copy of the file (with the same name) in the
  working directory of your project.

5. In the Project Explorer, right-click WebClass1 (WebClass1.Dsr), and click
  View Code on the shortcut menu. Replace the WebClass Start event code with
  the following code:

        Private Sub WebClass_Start()
           Set NextItem = Template1
        end Sub

  You use the NextItem property to shift processing from one WebItem to another
  during a single request. This causes the Template1_Respond event to fire.

6. Paste the following code in the Template1_Respond event:

        Private Sub Template1_Respond()
            Template1.WriteTemplate
        End Sub

  The WriteTemplate method sends the contents of Template1 to a client browser
  window. (Template1 is the HTML file that you imported into the IIS
  application.) If you do not put anything in this event, and you run the
  project, the browser displays a blank page.

7. Press the F5 key to run the project. The Project Properties dialog box
  appears in Visual Basic. On the Debugging tab, make sure that Start component
  is set to WebClass1, and then click OK. The WebClass designer prompts you to
  create a Virtual Root, which is required in order to run the WebClass. After
  you enter a name for the Virtual Root, click OK.

8. The page that you created now appears in the browser. After you browse the
  project, click End on the Run menu in Visual Basic. In the Project Explorer,
  right-click WebClass1 (WebClass1.Dsr), and then click View Code on the
  shortcut menu. Replace the Template1_Respond event code with the following
  code to create a second example:

     Private Sub Template1_Respond()
     'Write a reply to the user.
       With Response
          .Write "<html>"
          .Write "<body>"
          .Write "<h1>WebClass1's Starting Page</h1>"
          .Write "<p>Response was created in the Template1_Respond event</p>"
          .Write "</body>"
          .Write "</html>"
      End With
     End Sub

9. Press the F5 key to run the project. After you browse the project, click End
  on the Run menu in Visual Basic.

10. On the Project menu in Visual Basic, click <Project Name> Properties.
  On the General tab, select the following project properties check boxes for
  optimal performance:

   - Retain In Memory
   - Unattended Execution
   - Apartment Threaded for the Threading Model
