Invoked in:
Server
Message from Partner:
WM_DDE_UNADVISE
Remarks:
This event is invoked in a server when a partner wants to terminate a previously established advise state. An application should retrieve the item name (DDEGetItemName) if it is not certain to which item the DDEUnAdvise request corresponds, and respond with a positive or negative acknowledgment, depending on the result of this test. A zero-length ItemName_SV indicates that the partner wants to terminate all advise states associated with that conversation ID.
Required Response:
Upon receipt of a request to terminate an advise state, the DDE protocol requires that the server respond as follows. The server must respond to this event before attempting to transmit another event to the partner.
