[求助]为什么消息钩子会执行两次?不是键盘钩子
WH_GETMESSAGE: Process or modify all messages (of any type) for the system whenever a GetMessage or a PeekMessage function is called. 是不是除了windows消息循环中的默认调用 whlie(GetMessage()) { DispatchMessage(); } ,程序中的其他地方还调用了PeekMessage(MYMSG_MOVE)? |

[讨论]PostThreadMessage/WM_DESTROY为什么没反应
The thread to which the message is posted retrieves the message by calling the GetMessage or PeekMessage function. The hwnd member of the returned MSG structure is NULL. Messages sent by PostThreadMessage are not associated with a window. As a general rule, messages that are not associated with a window cannot be dispatched by the DispatchMessage function. Therefore, if the recipient thread is in a modal loop (as used by MessageBox or DialogBox), the messages will be lost. |

[讨论]PostThreadMessage/WM_DESTROY为什么没反应
PostThreadMessage 返回1是成功啊 msdn: If the function succeeds, the return value is nonzero. |
