The Visual Basic Power Packs Line and Shape controls are a set of three graphical controls that enable you to draw lines and shapes on forms and containers.

LineShape control -is used to draw horizontal, vertical, and diagonal lines.

 OvalShape control is used to draw circles and ovals.

 RectangleShape control is used to draw rectangles and squares.

        Dim testLine As New LineShape
        ShapeCon.Parent = Me
        testLine.Parent = ShapeCon
        testLine.StartPoint = New System.Drawing.Point(10, 10)
        testLine.EndPoint = New System.Drawing.Point(300, 300)
