SUMMARY
=======

When creating a CMDIChildWnd, the parent of the multiple document interface
(MDI) window is a "MDICLIENT" control. The handle to the parent frame window can
be retrieved in the following way:

      hwnd =::GetParent(lpcreatestruct.hwndParent);

Alternatively, use the following

      CMDIFrameWnd* pFrame = (CMDIFrameWnd*)GetParentFrame();

to acquire a pointer to the parent MDI frame window object.

NOTE: GetParentFrame is declared to return a pointer to a CFrameWnd object, and
therefore it is necessary to typecast the result to a CMDIFrameWnd object.
