画直线问题

purana

帮我看看这代码..只能画水平线...不能画任意角度的直线...请大家帮我修改一下... Option Explicit Dim MouseDowned As Boolean Dim oleX As Single Dim oleY As Single Dim NewX As Single Dim NewY As Single Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single) MouseDowned = True oleX = X oleY = Y NewX = oleX NewY = oleY End Sub Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) If MouseDowned Then If Button = vbLeftButton Then Me.Line (oleX, oleY)-(NewX, NewY) NewX = X: NewY = Y End If End If End Sub Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single) MouseDowned = False End Sub
