Question

为什么ActiveX中的对话框不响应PreTranslateMessage

Answer 1

MSDN说:
----------MFC--------------
CWnd::PreTranslateMessage
Used by class CWinApp to translate window messages before they are dispatched to the TranslateMessage and DispatchMessage Windows functions.
CWnd::WindowProc
Provides a Windows procedure (WindowProc) for a CWnd object. It dispatches messages through the window’s message map.
显然只有通过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！
还有就是所有的消息都通过WindowProc所以只要重载这个函数就一定能得到你要的消息！
