New Post: How to determine endpoints of multi-part polyline

I haven't had any responses so thought I'd give a simpler explanation. I've got a multipart polyline shape composed of contiguous segments. I'm trying to figure out how I can determine what the endpoints of the polyline are, since iterating over the points via get_Point(x) does not return the points in the order in which they appear on the map. As a result, get_Point(0) and get_Point(Numpoints-1) do not return the endpoints. I am quite stuck here so any input will be greatly appreciated.

Thank you,

Don
