FIX: Type Mismatch Error When Compiling UserControl (223111)

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a new ActiveX Control project in Visual Basic. UserControl1 is created by default.
2. Save and compile UserControl1 as Project1.OCX.
3. On the Project menu, click Project1 Properties. Click the Component tab and confirm that Version Compatibility is set to Project Compatibility.
4. On the File menu, click Add Project. Select ActiveX DLL in the Add Project dialog and click OK. (This will create a project group).
5. On the Project menu, click Components. Check the Project1 VBP you just created and click OK.
6. Add the following code to the General Declarations section of Class1:

   Option Explicit
   
   ' local object reference to the ActiveX Usercontrol
   Private WithEvents ctlUserControl As Project1.UserControl1
   
   Public Sub InitControl(ctlControl As Object)
   
       ' create a local reference to the Usercontrol that
       ' is passed in through this method. This is where
       ' the run-time error will be generated.
       Set ctlUserControl = ctlControl
       
       ' display a dialog that the reference was set properly
       MsgBox "ActiveX Usercontrol Reference Was Set", vbOKOnly, "ActiveX DLL Message"
       
   End Sub
   					

7. Save and compile the Project Group.
8. Create a new Standard EXE Project. Form1 is created by default.
9. On the Project menu, click Components. Check the Project1 ocx you just created and click OK.
10. Site a copy of UserControl1 onto the default form (Form1).
11. Add the following code to the General Declarations section of Form1:

    Option Explicit
    
    ' local object reference to the ActiveX DLL object
    Private cTestServer As Object
    
    Private Sub Form_Load()
    
        ' create an instance of the ActiveX DLL Object
        Set cTestServer = CreateObject("Project2.Class1")
        
        ' call a method of the object, passing in the usercontrol
        cTestServer.InitControl UserControl11
        
    End Sub
    					

12. Press the F5 key to run the project. The project will load and run without error.
13. Save and compile the Standard EXE.
14. Open the Project Group that contains the ActiveX DLL and ActiveX Usercontrol.
15. Compile the Project Group ten (10) times.
16. Open the Standard EXE project.
17. Press the F5 key to run the project. The run-time error will be generated.
