vb编程中在控件label1上点击左键移动鼠标使整个窗体也一移动，编码怎么写呀

添加一个label控件

'窗体代码
Private downx As Long
Private downy As Long
Private xx As Long
Private yy As Long
Private MouseDown As Boolean

Private Sub label1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
downx = X
downy = Y
MouseDown = True
End Sub

Private Sub label1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
xx = X
yy = Y
If MouseDown = True Then Me.Move Me.Left + (xx - downx), Me.Top + (yy - downy)
End Sub

Private Sub label1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
MouseDown = False
End Sub

这样就行了!!
