I'm sure you can port this VB ;-)

Dim p As New Pen(Color.Red)
p.StartCap = System.Drawing. Drawing2D.LineC ap.ArrowAnchor
p.EndCap = System.Drawing. Drawing2D.LineC ap.Flat
p.Width = 2
Me.CreateGraphi cs.DrawLine(p, 200, 200, 400, 400)

Those caps are pretty small, but there is a CustomLineCap class that I
believe lets you define your own caps using a Path. I've never used the
Custom option myself, sorry.

Hello,

I tried it with your code like that:

System.Drawing. Pen myPen = null;
myPen.StartCap = System.Drawing. Drawing2D.LineC ap.ArrowAnchor;
myPen.EndCap = System.Drawing. Drawing2D.LineC ap.Flat;
myPen.Width = 2;
System.Drawing. Graphics formGraphics = this.CreateGrap hics();
formGraphics.Dr awLine(myPen, a, b, c, d);
myPen.Dispose() ;
formGraphics.Di spose();

But I always get a NullReferenceEx ception. Does anybody know what went wrong
here?
