SYMPTOMS

You receive a Type Mismatch Error (13) when assigning a UserControl to a variable if the UserControl is in the same project as the assigning code. The problem does not occur if the UserControl is in a different project or compiled.

RESOLUTION

Load the form containing the UserControl before assigning the UserControl to the variable. (See step 8 in Steps to Reproduce Behavior below.)

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

Start a new Standard EXE project in Visual Basic. Form1 is created by default.
Add a UserControl to the project.
Place an instance of the UserControl on Form1.
Add a Standard Module to the project.

Insert the following code into Module1:

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

Set the Startup Object of the project to Sub Main.
Run the project. You should receive "Run-time error 13. Type Mismatch."

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
