Create and Compile an ActiveX Document

1. Start a new ActiveX Document DLL project in Visual Basic. UserDocument1 is created by default.
2. Add a TextBox control to UserDocument1.
3. In the TextBox property sheet, set the WhatsThisID property to the topic number of your Help file.
4. Copy the following code to the Code window of Form1. Add the name of the Help file to the appropriate line:

   Option Explicit
   
   Private Sub UserDocument_Initialize()
      App.HelpFile = App.Path & "<Help File Name>"
   End Sub
       
   					

5. Save the project as UserDocument.vbp. Compile the project into the file UserDocument.dll.
6. Close the ActiveX Document project.

Create a Standard EXE Project

1. Start a new Standard EXE project in Visual Basic. Form1 is created by default.
2. Add the Microsoft Internet Controls to the project. For more information about adding ActiveX controls to your project, see the REFERENCES section of this article.
3. Add a WebBrowser Control project to your Standard EXE project. WebBrowser1 is created by default.
4. In the Form1 property sheet, set the following properties:
   • BorderStyle=3-Fixed Dialog
   • WhatsThisButton=True
   • WhatsThisHelp=True
   
   
5. Copy the following code to the Code window of Form1. Add the Help file name to the appropriate line:

   Option Explicit
   
   Private Sub Form_Load()
      App.HelpFile = App.Path & "<Help File Name>"
      WebBrowser1.Navigate App.Path & "\UserDocument1.vbd"
   End Sub
       
   					

6. On the Run menu, select Start, or press the F5 key to start the program. The ActiveX Document appears in the WebBrowser control. In the Title Bar of Form1, click the Help button. The cursor changes to a question mark. Click the ActiveX Document in the WebBrowser control.
   
   BUG: The appropriate topic from the Help file does not appear. The expected behavior is for the appropriate topic to appear.
