键盘挂钩问题
我在D4,D5中编写一个键盘挂钩，在SetWindowsHookEx(int idHook,HOOKPROC lpfn,HINSTANCE hMod,DWORD dwThreadId);中的idHook参数设为WH_KEYBOARD,但在windows2000下对Ctrl+Alt+Del和windows键不起作用。在一本书中介绍idHook参数还可以设为WH_KEYBOARD_LL(只在windows2000有用)，但在D4,D5中不支持。有谁知道怎样挂上这两个消息。急急急 问题点数：20、回复次数：6Top

具体的你看一下这个记录PKBDLLHOOKSTRCUT
它有vkcode的成员,就是它了,后面不用我写了吧
