INFO: Retrieving the CMDIChildWnd Parent Window

ID: Q101184

The information in this article applies to:

The Microsoft Foundation Classes (MFC), used with:
- Microsoft Visual C++ for Windows, 16-bit edition, versions 1.0, 1.5, 1.51, 1.52
- Microsoft Visual C++, 32-bit Editions, versions 1.0, 2.0, 2.1, 4.0

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.
