WH_GETMESSAGE 为什么无法取得线程内「所有消息」？
//*************************************************************
都说
WH_GETMESSAGE 是在 GetMessage 和 PeekMessage 时动作的，
可为什么它也不能取得线程之所有消息呢？
难道非要按装好几个钩子才能得到 所有消息？
//*************************************************************
比如 WM_MOVE 就必须用 WH_CBT 或 WH_CALLWNDPROC 等 来获取。
但是WH_CALLWNDPROC 又不能取得 WH_LBUTTONUP 等鼠标消息。
用WH_MOUSE的话只能取得鼠标消息。
至于 WH_MSGFILTER 好象也不是很好用。

钩子是在消息从消息队列获取时候被触发的吧
不是所有的Windows消息都进消息队列的,有些消息直接走向了窗口过程
估计是这个原因
时间充裕可以看看这些,呵呵
