IConnectionPoint::Unadvise (Compact 2013)
3/26/2014
This method terminates an advisory connection previously established through IConnectionPoint::Advise. The dwCookie parameter identifies the connection to terminate.
Syntax
HRESULT Unadvise(
DWORD dwCookie
);
Parameters
- dwCookie
[in] Connection token previously returned from IConnectionPoint::Advise.
Return Value
This method supports the standard return value E_UNEXPECTED, as well as the following:
- S_OK
The connection was successfully terminated.
- CONNECT_E_NOCONNECTION
The value in dwCookie does not represent a valid connection.
Remarks
When an advisory connection is terminated, the connection point calls the Release method on the pointer that was saved for the connection during the IConnectionPoint::Advise method.
This Release reverses the AddRef that was performed during the IConnectionPoint::Advise when the connection point calls the advisory sink's QueryInterface.
To determine whether the platform supports this interface, see Determining Supported COM APIs.
