[GIS] ArcEngine 10 Polyline with arrow

arcgis-10.0arcgis-enginepolyline-creation

I was wondering if there is a way to draw a polyline but with an arrow head at the end point?

IPolyline line = new PolylineClass();
((IPointCollection)line).AddPoint((IPoint)sourceFeature.Shape);
((IPointCollection)line).AddPoint((IPoint)sinkFeature.Shape);

Just go in to the symbology menu and scroll down until you see an option for this type of line symbology (arrow at start, end, etc). If you're using ArcGIS 10, you even have the option to search for symbology by a certain parameter (ex - typing "helicopter" will bring you to a number of symbology options related to that keyword). If you're using ArcGIS 9, you can also add different symbol sets to your array of options. I only have ArcView 9.3, but the print screen I attached shows you what you need.
