Drawing with Mouse?

I want to write a really simple program or so I think. All I want to do is draw a line wherever the mouse moves, like clicking and holding in paint and just moving the mouse around.(Without clicking just moving the mouse) I then want to be able to clear the form by a simple click. Any ideas? And Possibly add some color changes in there too?


Thanks

Paste this sample code to a form ;)

Code:

---

Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    CurrentX = X
    CurrentY = Y
End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Select Case Button
        Case 1 'left button draws lines
            Line -(X, Y)
        Case 2 'right button changes color
            ForeColor = QBColor(Int(Rnd * 16))
        Case 3 'both buttons clear the form
            Cls
    End Select
End Sub

Thanks works great
