Remarks

The ITopologyContainer interface can be used to manage and create topologies within a feature dataset.  If your intention is to simply browse for the set of topologies in a feature dataset, it is not necessary to open the feature dataset and call the methods on ITopologyContainer.  The IFeatureDatasetNames::TopologyNames method can be used to efficiently obtain this information.  Careful consideration should be given to specifying the parameters when creating a topology.  Once the topology is built, none of the parameters can be modified.  In order to change properties such as cluster tolerance, the topology must be deleted and rebuilt with the new parameters.
