IOleObject::Unadvise

Deletes a previously established advisory connection.

HRESULT Unadvise(

DWORD dwConnection

//Token

);

Parameter

dwConnection: [in] Contains a token of nonzero value, which was previously returned from IOleObject::Advise through its pdwConnection parameter.

Return Values

This method supports the standard return value E_FAIL, as well as the following:

S_OK: Advisory connection deleted successfully.
OLE_E_NOCONNECTION: dwConnection does not represent a valid advisory connection.

Remarks

Normally, containers call IOleObject::Unadvise at shutdown or when an object is deleted. In certain cases, containers can call this method on objects that are running but not currently visible as a way of reducing the overhead of maintaining multiple advisory connections. The easiest way to implement this method is to delegate the call to IOleAdviseHolder::Unadvise.
