　　Dim i, x1 As Double, y1 As Double, x2 As Double, y2 As Double
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
i = 1
x1 = X
y1 = Y

End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
If i = 1 Then
x2 = X - x1+form1.lift
y2 = Y - y1+form1.top
form1.move x2,y2

End If
End Sub

Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
