Remarks

Pass in a valid UserClassID, UserID, UserSubID, and esriElementType and the corresponding Element ID (EID) in the logical network is returned.  If no network elements match the given UserClassID, UserID, UserSubID, and esriElementType, then 0 is returned.
If the network is part of a geometric network, the UserClassID and UserID correspond to the FeatureClassID and OID of the feature. The UserSubID is the ID of the subelement of the feature.
Entering a negative value for the UserSubID will return the first EID in the table that matches the specified UserClassID and UserID.  This is not necessarily the lowest-valued EID matching the specified UserClassID and UserID, nor necessarily the EID corresponding to the lowest-valued SubID.
