How do I reference the window that is the parent of a Container

If I have a code generated window with a code embedded container, How do I reference the Window from the container? I’ve tried Self.Parent, but while it doesn’t cause a compiler error, the result is not what I expect (trying to open a sheet window in the parent).

Dim WBackupJob1 As New Window Dim ccJob1 As New ccJobProgress ... WSheetStandy.ShowModalWithin Self.Parent

The sheet never appears.

Try self.TrueWindow

D’oh - and I knew that. It sucks getting old. :S
