If you have a standard or and advanced licence, you can use Snap(editing) or extend(editing) to fill your gaps.

This will give you more control of what you are doing (including maximum distance) than the integrate tool (which is available with any type of ...


Try this syntax: topoError = eErrorFeat.Next Do While Not (topoError Is Nothing) topologyExt.AddActiveError(topoError, esriTEEventHint.esriTENone) topoError = eErrorFeat.Next Loop You may want to confirm that eErrorFeat is not actually Nothing?
