IAddrBook::Unadvise

This content is outdated and is no longer being maintained. It is provided as a courtesy for individuals who are still using these technologies. This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.

Cancels a notification registration previously established for an address book entry.

HRESULT Unadvise(
  ULONG ulConnection
);

Parameters

  • ulConnection
    [in] A connection number that represents the registration to be canceled. The ulConnection parameter should contain a value returned by a prior call to the IAddrBook::Advise method.

Return Value

  • S_OK
    The registration was successfully canceled.

Remarks

Clients call the Unadvise method to stop receiving notifications about changes to a particular address book entry. When a notification registration is canceled, the address book provider releases its pointer to the caller's advise sink. However, the release can occur during the Unadvise call or at some later point, if another thread is in the process of calling the IMAPIAdviseSink::OnNotify method. When a notification is in progress, the release is delayed until the OnNotify method returns.
