Draw Tooltip

[Kayot]

Is there a way to give a line a tooltip?

        Dim myPen As New System.Drawing.Pen(System.Drawing.Color.Red)
        Dim formGraphics As System.Drawing.Graphics
        formGraphics = Me.CreateGraphics()

        'formGraphics.DrawLine(myPen, 0, 0, 180, 200)

        myPen.Dispose()

I'm not sure, how if it can even be done.
