Remarks

The Extract method returns a difference cursor corresponding to all rows in a class with a specific esriDifferenceType. IRow objects returned from a difference cursor are meant to be a read only. If row editing is desired the OID returned from the call to IDifferenceCursor::NextRow should be used in a call to the ITable::GetRow or ITable::GetRows methods.
