• Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, versions 5.0, 6.0

SYMPTOMS

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

Steps to Reproduce Behavior

1. Start a new Standard EXE project in Visual Basic. Form1 is created by default.



2. Add a UserControl to the project.



3. Place an instance of the UserControl on Form1.



4. Add a Standard Module to the project.



5. Insert the following code into Module1:

   
         Sub Main()
            Dim x As UserControl1
            Set x = Form1.UserControl11
         End Sub
    




6. Set the Startup Object of the project to Sub Main.



7. Run the project. You should receive "Run-time error 13. Type Mismatch."



8. To resolve the problem, change the code in step 5 to:

   
         Sub Main()
            Dim x As UserControl1
            Load Form1
            Set x = Form1.UserControl11
         End Sub
