/// true if managed resources should be disposed; otherwise, false.
protected override void Dispose(bool disposing)
{
if (disposing) {
if (components != null) {
components.Dispose();
}
}
base.Dispose(disposing);
}

///

protected override void OnPaint(PaintEventArgs e)
{
Point pt1 = new Point (150,200);
Point pt2 = new Point (150,400);
Point pt3 = new Point (300,300);
Pen p = new Pen (Color.Green);
base.OnPaint(e);
e.Graphics.DrawLine(p,pt1,pt2);
e.Graphics.DrawLine(p,pt2,pt3);
e.Graphics.DrawLine(p,pt3,pt1);
