IRowsetNotify::OnRowsetChange

Notifies the consumer of any change affecting the entire rowset.

HRESULT OnRowsetChange (
   IRowset *      pRowset,
   DBREASON       eReason,
   DBEVENTPHASE   ePhase,
   BOOL           fCantDeny);

Parameters

pRowset

[in]
A pointer to the rowset, because the consumer may be receiving notifications from multiple rowsets and this identifies which one is calling.

eReason

[in]
The reason for the event that caused this change. If this value is not recognized by the method, the method returns S_OK or DB_S_UNWANTEDREASON.

ePhase

[in]
The phase of this notification.

fCantDeny

[in]
When this flag is set to TRUE, the consumer cannot veto the event by returning S_FALSE because the provider cannot undo the event.

Return Code

S_OK

The method succeeded.

S_FALSE

The event/phase is vetoed by reason of logical objection or a failure to be able to implement.

DB_S_UNWANTEDPHASE

The consumer is not interested in receiving this phase for this reason. The provider can optimize by making no further calls with this reason and phase. The phases for other reasons are unaffected.

DB_S_UNWANTEDREASON

The consumer is not interested in receiving any phases for this reason. The provider can optimize by making no further calls with this reason.

E_FAIL

A consumer-specific error occurred. The provider continues the operation.

Comments

Possible reasons are any of the DBREASON_ROWSET_* reasons.

No phases occur; this method is equivalent to DBEVENTPHASE_DIDEVENT.
