IDDEAcknowledgeEvent

The IDDEAcknowledgeEvent class is the base class for the Dynamic Data Exchange (DDE) acknowledge-event information classes.

An object of this class or one of its derived classes is created when an IDDEClientConversation object or IDDETopicServer object needs to pass acknowledgment information to the client or server application. You do not construct objects of this class.
