Window Procedure Entry Points

To protect MFC window procedures, a module static links with a special window procedure implementation. The linkage occurs automatically when the module is linked with MFC. This window procedure uses the AFX_MANAGE_STATE macro to properly set the effective module state, then it calls AfxWndProc, which in turn delegates to the WindowProc member function of the appropriate CWnd-derived object.
