Hi Forum, I would like to set a bitmap (sign of firm) in the frame of the mainframe of a mdi-document! normaly its windows-default gray. Have somebody a solution? Thanks!

Here's the solution from The MFC Answer Book by Eugène Kain:

1. Create a new CWnd-derived class (we'll call it CMdiBackground). This will be used to subclass the MDI client window.
2. Add handlers to this class for WM_ERASEBKGND and WM_SIZE.
3. In OnEraseBkgnd, call CWnd::OnEraseBkgnd() and then do whatever custom painting you want.
4. Your OnSize() handler should call CWnd::OnSize(), followed by Invalidate(TRUE).
5. Add a CMdiBackground member variable (call it m_wndMdiBackground) to your CMainFrame class.
6. Add this code to the end of CMainFrame::OnCreate() if ( !m_wndMdiBackground.SubclassWindow(m_hWndMDIClient)) { return -1; }
