关于截获鼠标消息的钩子耗系统资源的问题
本帖最后由 sd007 于 2009-5-16 21:36 编辑截获鼠标消息可以用两种方法：（以下两个例子都是超级版主pcbar发的）
1.用SetWindowsHookEx钩子技术，例子：http://www.autoitx.com/attachment.php?aid=410&k=10943da8290560d3f8ac93f8eed673e0&t=1237813540，这种方法在CPU资源紧张时（比如打开一个有flash动画的网页时），能明显感觉到鼠标移动反应有点迟钝，它的优点是可以中断鼠标消息的传递
2.用hook.dll，例子：http://www.autoitx.com/attachment.php?aid=412&k=8782fa6495d6c50b1ffbb0e7141d1bd6&t=1237813540，用这种方法在CPU资源紧张时，不会感觉到鼠标移动反应有迟钝，但好像不能中断鼠标消息的传递。
请问用什么方法能截获鼠标消息，并中断消息的传递，同时又不会耗CPU资源？
我的系统是WIN2003，CPU：P4 3.3G，内存：2G
[ 本帖最后由 sd007 于 2009-3-23 21:55 编辑 ] 第一个问题:
反应快与慢是看SetWindowsHookEx执行后与CallNextHookEx执行前的代码,当中的代码执行肯定需要些时间,你说的在CPU吃紧时的问题是存在的
第二:
如果要截获的话应该是在收到消息后不执行CallNextHookEx就可以了吧,至少我是这样理解的.
BTW:以上仅为新手意见,希望不会误导任何人.
回复 2# ceoguang 的帖子
1.SetWindowsHookEx执行后与CallNextHookEx执行前,之间就是没有执行代码，鼠标移动反应还是一样有点迟钝2..用hook.dll没有CallNextHookEx函数 AU3的执行速度只能这样. 用第2种方法丝毫不会感觉到鼠标移动反应有迟钝，有没有hook.dll的相关资料？用hook.dll能中断鼠标消息的传递吗？
我把应用hook.dll的源码贴出来，请指教：
