1. CWnd::PostMessage
Bool PostMessage(UINT message,WPARAM wParam=0,LPARAM lParam=0);
返回值：Nonzero if the message is posted; otherwise 0.（即消息是否提交成功）
说明：将消息放入windows消息队列，就直接返回，需要通过使用GetMessage或PeekMessage来获得返回的消息
2. CWnd::SendtMessage
LRESULT SendMessage(UINT message,WPARAM wParam=0,LPARAM lParam=0);
返回值：The result of the message processing; its value depends on the message sent.
说明：直接发给windows，不处理完，不返回
