IConnectionPoint::Unadvise

  • Article

This method terminates an advisory connection previously established through IConnectionPoint::Advise. The dwCookie parameter identifies the connection to terminate.

HRESULT Unadvise(
  DWORD dwCookie 
);

Parameters

  • dwCookie
    [in] Connection token previously returned from IConnectionPoint::Advise.

Return Values

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.

Requirements

OS Versions: Windows CE 3.0 and later.
Header: Ocidl.h, Ocidl.idl.
Link Library: Ole32.lib, Uuid.lib.
