Accessing the Logical Network - Retrieve From-To EdgesID from polyline shapefile

HarisBallis

Hello

My project involves finding the shortest path within a polyline shapefile, without using the network analyst (not an owner of a licence for the specific product).
Eventually i need the ID's of the nodes(edges) that "create" this network although i cannot find where this information is stored.
After some research I believe the answer lays somewhere the INetwork interface but my skills at ArcObjects with VBA are still novice.

I'd be glad if someone could help me further.

From result of trace solver you can use EIDHelperClass for get feature

            IEIDHelper eidHelper = new EIDHelperClass();
            eidHelper.GeometricNetwork = geometricNetwork;
            eidHelper.ReturnGeometries = true;
            eidHelper.ReturnFeatures = true;

            IEnumEIDInfo enumEIDinfo = eidHelper.CreateEnumEIDInfo(eids);
            enumEIDinfo.Reset();
            IEIDInfo eidInfo = enumEIDinfo.Next();
            while (eidInfo != null)
            {
                IFeatureClass featureClass = eidInfo.Feature.Class as IFeatureClass;
                IFeature feature = eidInfo.Feature;
                int featureClassID = featureClass.FeatureClassID;
                ...                
                eidInfo = enumEIDinfo.Next();
            }

you can also use IEIDHelper::AddField() to get attribute for field added and IEIDHelper::get_DisplayEnvelope() for get feature valid cointained in a envelope
