我做了一个全局键盘钩子，但连续几次运行没有卸载，现在该如何卸载呢？

[djhdu]

我用此语句SetWindowsHookEx(WH_KEYBOARD,(HOOKPROC)KeyBoardProc,0,0); 创建了一个全局钩子，但是刚开始没有调用UnhookWindowsHookEx函数，造成程序退出以后，全局钩子依然存在，监视所有的信息，我现在想问一下，如何去掉这个系统中还有的全局钩子呢？

“造成程序退出以后，全局钩子依然存在”
如果没记错的话，进程终止的话，系统自动撤销进程还未释放的钩子。
你可以检查一下包含全局钩子的DLL，这时应该已经没有其他进程加载这个DLL了。

Windows2000的话，会自动处理~
98的话估计现在已经蓝屏了~
：）
注销一下或者重启就可以了……

应该没有这个可能的。进程结束会自动卸载钩子的。

[qitengyi]

在DLL的入口函数中加入
if(dwReason == DLL_PROCESS_DETACH)
卸载钩子函数

这样应该可以卸载掉

"造成程序退出以后，全局钩子依然存在",你没搞错吧

哦，如果是这样的话，那我的vc就是出问题了，每次Debug调试程序，调试窗口里出现一堆如下的数据，不论调试哪一个程序都会出现下面类似的内容，好像是纪录了每一个消息，这是怎么引起的呢？

关闭程序以后还有？
没有遇到过！

SetWindowsHookEx(WH_KEYBOARD,(HOOKPROC)KeyBoardProc,0,0);
第三個參數是0嗎??應該是DLL的默快句柄吧!!
