下面是我为全局键盘钩子建立的DLL程序(基本上改自programming windows的源程序)

#endifHANDLE g_hinstDll;
EXPORT LRESULT CALLBACK KbProc(int,WPARAM,LPARAM);如果不用dll做全局钩子是可以实现hook住SHIFT键的,但是象上面一样
用dll却实现不了hook,请大虾们帮我看看问题出在哪里?(编译是可以通过的
设置应该也没问题,我改的是programming windows里面的一个dll小程序)
对了,顺便问一下,dll程序怎么调试呀?每次想设断点都失败。谢谢

2:你的回调函数Export干什么? 它不是这一点阿!
