I have created a topology graph of a polygon feature and I want to find the individual FIDS of the lines of the polygon. I want to construct an adjacency matrix to create the shortest path. How can I do this with ArcObjects programming with VBA?
The individual lines will now have their own feature ids (they are not features- per se), but you can iterate over the individual Topology edges using IEnumTopologyEdge (there is also a sample available).
You can find more information about how to work with Topology Edges here: http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#//0001000002vt000000
