    SubclassWindow causes stack overflow in CMainFrame::OnCreate()

    I recently upgraded my MS Visual Studio 2008 to Service Pack 1 to take advantage of the MFC enhacements (Feature Pack).

    I orginally had an MDI app in which I had changed the background in the main client area to tile a company logo. I originally followed the instructions in MSDN: Q129471. Worked beautifully since MS VS 2002 .NET.

    CMainFrame was derived from CMDIFrameWnd, and my overloaded CMainFrame::OnCreate() looked like

    Code:
         BOOL CMainFrame::CreateClient(LPCREATESTRUCT lpCreateStruct, CMenu* pWindowMenu)
         {
             if(CMDIFrameWnd::CreateClient(lpCreateStruct, pWindowMenu))
             {
                    m_MyMdiClientWnd.SubclassWindow(m_hWndMDIClient);
                    return TRUE;
              }
             else
                   return FALSE;
           }
    BUT, now with the CMainFrame derived from CMDIFrameWndEx, the call to SubclassWindow() causes a stack overflow.

    Someone else has had to come across this same issue!
