Cancels the sending of notifications previously set up with a call to the IMAPITable::Advise method.

HRESULT Unadvise(
ULONG_PTR ulConnection


[in] The number of the registration connection returned by a call to IMAPITable::Advise.


The call succeeded.

Use the IMAPITable::Unadvise method to release the pointer to the advise sink object passed in the lpAdviseSink parameter in the previous call to IMAPITable::Advise, thereby canceling a notification registration. As part of discarding the pointer to the advise sink object, the object's IUnknown::Release method is called. Generally, Release is called during the Unadvise call, but if another thread is in the process of calling the IMAPIAdviseSink::OnNotify method for the advise sink, the Release call is delayed until the OnNotify method returns.

For more information on the notification process, see Event Notification in MAPI. For specific information about table notification, see About Table Notifications. For information about using the IMAPISupport methods to support notification, see Supporting Event Notification.

For MFCMAPI sample code, see the following table.






MFCMAPI uses the IMAPITable::Unadvise method to cancel notifications for the table.
