MORE INFORMATION

Steps to Reproduce Problem

1. Create an ActiveX Control project.
2. Click Add Form on the Project menu to add a form to the project.
3. Add the following code to the UserControl:

         Public CtlProp as string 'user created property
   
         Private Sub UserControl_Click()
             CtlProp = "passed value" 'set the property
             Form1.Show
         End Sub
   
         Private Sub UserControl_Initialize()
             BackColor = vbRed
         End Sub
   
   						

4. Add the following code to Form1:

         Private Sub Form_Activate()
            MsgBox Usercontrol1.CtlProp '<--- Error Occurs Here
         End Sub
