kb_event函数的使用 

下面的函数可以利用kb_event实行一些系统操作


Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)

Private Const VK_LWIN = &H5B
Private Const KEYEVENTF_KEYUP = &H2
Private Const VK_APPS = &H5D
Private Const VK_PLAY = &HFA 

Private Sub DoAction(Index As Integer)
Dim VK_ACTION As Long

Select Case Index
Case 0: '打开资源管理器
VK_ACTION = &H45
Case 1: '查找文件
VK_ACTION = &H46
Case 2: '最小化所有窗口
VK_ACTION = &H4D
Case 3: '运行程序
VK_ACTION = &H52
Case 4: '弹出Win菜单
VK_ACTION = &H5B
Case 5: '将计算机转入睡眠状态
VK_ACTION = &H5E
Case 6: '执行Windows帮助
VK_ACTION = &H70
End Select

Call keybd_event(VK_LWIN, 0, 0, 0)
Call keybd_event(VK_ACTION, 0, 0, 0)
Call keybd_event(VK_LWIN, 0, KEYEVENTF_KEYUP, 0)
End Sub
