VB识别鼠标左右键

VB识别鼠标按下事件是MouseDown事件，这个事件中可以识别鼠标不同的按键，可是如果要求分辨出先按下哪个键，这样可以识别吗？举例说明一下：要求 先按下鼠标右键，再按下鼠标左键，最后两个键一起放开，当上述事件发生时，执行一些代码。应该怎么实现？

MouseDown事件中 有罩卖裂个button变量配芦 当鼠标右键按下时 button的值为vbRightButton，左键按下为vbRightButton,滚轮按下为4知道这个就好实现你所说物闭的功能了你在Mousedown事件中添加下面代码：if button = vbRightButton thenmsgbox "按下右键"elseif button = vbLeftButton thenmsgbox "按下左键"判断左右键同时放开代码如下：Option Explicit
Dim OldButton As Byte
Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, _
Y As Single)
If OldButton + Button = 3 Then
MsgBox "鼠标左右键同时放开'"
End If
OldButton = Button
End Sub
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, _
Y As Single)
OldButton = 0
End Sub
