Question

VB只屏蔽ctrl或者alt，为什么下面的代码 还是不能屏蔽alt+ctrl+Z？？？？？

Dim fEatKeystroke As Boolean
If (nCode = HC_ACTION) Then
If wParam = WM_KEYDOWN Or wParam = WM_SYSKEYDOWN Or wParam = WM_KEYUP Or wParam = WM_SYSKEYUP Then
CopyMemory p, ByVal lParam, Len(p)
fEatKeystroke = ((p.vkCode = 9)) Or ((p.vkCode = 27)) Or ((p.vkCode = 91)) Or ((p.vkCode = 92)) Or ((p.vkCode = 17)) Or ((p.vkCode = 18))
End If
End If
If fEatKeystroke Then
CallKeyHookProc = 1 ' 设置为 1 可以屏蔽按键
Else
CallKeyHookProc = CallNextHookEx(0, nCode, wParam, ByVal lParam)

这段代码晦涩难懂，还有很多局外变量和过程，很难猜测问题所在。
建议冲如你把他适当转槐明化散明启一下再来提问。
