Date: 2008jun6 Updated: 2010feb4 Framework: MFC Language: C/C++ Q. MFC: How do I get the HWND handle for the main Window of my MFC program? A. First use AfxGetMainWnd() to get the CWnd class then use GetSafeHwnd() on that as this function demonstrates:

// AfxGetMainWnd() is broken in Visual Studio 2005 so here's my own inline CWnd *MyGetMainWnd() { CWinApp *app; if ((app = AfxGetApp()) == NULL) return NULL; return app->m_pMainWnd; } inline HWND GetMainHwnd() { CWnd * wnd; if ((wnd = MyGetMainWnd()) == NULL) return NULL; return wnd->GetSafeHwnd(); }
