IOleObject::Unadvise (Compact 2013)
3/26/2014
This method deletes a previously established advisory connection.
Syntax
HRESULT Unadvise(
DWORD dwConnection
);
Parameters
- dwConnection
[in] Contains a nonzero DWORD previously returned by IOleAdviseHolder::Advise in pdwConnection.
Return Value
If the advisory connection deleted, the return value is S_OK.
If the dwConnection parameter does not represent a valid advisory connection, the return value is OLE_E_NOCONNECTION.
Remarks
IOleAdviseHolder::Unadvise is intended to be used to implement IOleObject::Unadvise to delete an advisory connection.
In general, you would use the OLE advise holder having obtained a pointer through a call to CreateOleAdviseHolder.
Usually, containers call this method at shutdown or when an object is deleted. In certain cases, containers could call this method on objects that are running but not visible, as a way of reducing the overhead of maintaining multiple advisory connections.
To determine whether the platform supports this interface, see Determine Supported COM APIs.
