全局鼠标钩子！

[wangrenjie_jeny]

最近做了个全局鼠标钩子，在xp下运行正常，到vista下钩子在一些时候无效，比如IE浏览器，一些对话框什么的，是不是有什么地方小弟没有注意，还请大虾们指点一二！

具体代码？

xp可以而vista不可以

大部分是权限的关系

你是administator运行的么

[wangrenjie_jeny]

嗯！

运行前需要取得权限

[wangrenjie_jeny]

怎么使钩子运行时取得权限啊？

[ITwudi]

SetWindowsHookEx这函数返回已经错误了.
你代码里没有检查,,我曾经碰到过这个问题..

[ITwudi]

不好意思...貌似看错了..我以前的钩子程序不是捕捉WH_MOUSE的.
hmou=SetWindowsHookEx(/*WH_MOUSE*/14,(HOOKPROC)MouseProc,hins,0);
你看一下这个是正常返回了吗?
这边没有环境,不能现在验证了.
VISTA下一般都是权限问题,你可以让你的程序"以管理者身份运行"试试看,能不能正常运行.
