Call this member function to retrieve the window's top-level parent.

CWnd* GetTopLevelParent( ) const;

Identifies the top-level parent window of the window.

The returned pointer may be temporary and should not be stored for later use.

GetTopLevelParent is similar to GetTopLevelFrame and GetTopLevelOwner; however, it ignores the value set as the current owner window.
