Description

The IDifferenceCursor interface returns a cursor of OIDs and IRows based upon the difference type used with IVersionedTable or IDataChangesEx.

The set of object IDs returned is dependant on the difference type category. For example, if the difference type DeleteNoChange is applied, the outbound row will be nothing since the row no longer exists.  In this case it is necessary to enumerate until the returned OID equals -1.  Use the value returned by the outbound OID parameter to retrieve the row in the other version of the table where the row has not yet been deleted.

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.
