HookAPI KBDLLHOOKSTRUCT的问题

我想调用API HOOK
Public Function KeyProc(ByVal nCode As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private KeyStruct As KBDLLHOOKSTRUCT
CopyMemory KeyStruct, ByVal lParam, Len(KeyStruct)
CallNextHookEx KeyBoardHook, nCode, wParam, lParam
End Function
有没有人能解释下KBDLLHOOKSTRUCT到底是怎么样的结构， 每个成员有什么作用？

Answer 1

这是api中的定义，你只能照搬和使用它

Private Type KBDLLHOOKSTRUCT '这个是低级键盘钩子的索引值

vkCode As Long '虚拟按键码(1--254)
scanCode As Long '硬件按键扫描码
flags As Long '键按下：128 抬起：0
time As Long '消息时间戳间
dwExtraInfo As Long '额外信息

End Type
