Private Sub ShowPointConverter(ByVal e As PaintEventArgs)

    ' Create the PointConverter.
    Dim converter As System.ComponentModel.TypeConverter = _

    Dim point1 As Point = _
        CType(converter.ConvertFromString("200, 200"), Point)

    ' Use the subtraction operator to get a second point.
    Dim point2 As Point = Point.op_Subtraction(point1, _
        New Size(190, 190))

    ' Draw a line between the two points.
    e.Graphics.DrawLine(Pens.Black, point1, point2)
End Sub
