CWnd::GetParent
Call this function to get a pointer to a child window's parent window (if any).
CWnd* GetParent( ) const;
Return Value
See the Return Values section in GetParent in the Windows SDK.
Remarks
The GetParent function returns a pointer to the immediate parent (if it exists). In contrast, the GetParentOwner function returns a pointer to the most immediate parent or owner window that is not a child window (does not have the WS_CHILD style). If you have a child window within a child window GetParent and GetParentOwner return different results.
