BUG: Parent Property Returns Invalid Object Type for UserControl

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a new Standard EXE project. Form1 is created by default.
2. Select Add Project from the File menu and add a new ActiveX Control project. UserControl1 is created by default.
3. Add two CommandButtons to UserControl1, and add the following code to the General Declarations section of UserControl1:

         Option Explicit
         Private Sub Command1_Click()
            MsgBox Command1.Parent.ScaleX(12)
         End Sub
   
         Private Sub Command2_Click()
            Dim oTmp As Object
            Set oTmp = Command2.Parent
            MsgBox oTmp.ScaleX(12)
         End Sub
   
         Public Function ScaleX(Width As Single) As Single
            ' You need to expose the ScaleX function so that it
            ' can be called from the Parent property.
            ScaleX = UserControl.ScaleX(Width)
         End Function
   
         Private Sub UserControl_Initialize()
            Command1.Caption = "Early-Bound"
            Command2.Caption = "Late-Bound"
         End Sub
   
   						

4. Close the UserControl design windows and add an instance of UserControl1 to Form1. Make certain both buttons are visible.
5. Press the F5 key to run the project in the IDE.
6. Press the "Early-Bound" button and note that a run-time error occurs, even though the parent control supports the ScaleX method. The error is caused by Visual Basic calling through the vtable into the ScaleX method of a Form object and not the usercontrol.
7. Press the "Late-Bound" button and note that the method succeeds as expected.
