Remarks

The SourceID parameter is the unique ID assigned to the NetworkSource in the network dataset.

The EnumNetworkElement enumeration object returned by the ElementsBySource property is recycling.  For enumerations with more than one network element returned, this means that the network element object returned by the first call to Next is expected to be reused in subsequent calls to Next.

For edge elements, the element(s) returned in the enumeration will be oriented in the esriNEDAlongDigitized Direction.  To get the edge element in the esriNEDAgainstDigitized Direction, call INetworkEdge::QueryEdgeInOtherDirection on the returned edge.
