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.
