对话框消息在PreTranslateMessage怎么无法捕获

MSDN说:----------MFC--------------CWnd::PreTranslateMessageUsed by class CWinApp to translate window messages before they are dispatched to the TranslateMessage and DispatchMessage Windows functions.CWnd::WindowProcProvides a Windows procedure (WindowProc) for a CWnd object. It dispatches messages through the window’s message map.显闹亏困然只有通过TranslateMessage和DispatchMessage函数传过来的消息才能在PreTranslateMessage中捕捉到，什么消息是通过这两个函数我不消息，不过鼠标和键盘还有Timer是一定会过的液念！还有就是所有的消息都通过WindowProc所以只要重空纤载这个函数就一定能得到你要的消息！
