DDELINK KeywordDescription
HOTServer sends linked data, as soon as that data changes. When the server notifies the OpenInsight control of the change, the DDEADVISE event handler for the associated control is invoked, and the data specified by the connection is passed.
WARMThe DDEADVISE event for the associated OpenInsight for Workgroups control is invoked by the server, but the affected data is not copied to that control until the DDEDATA property is set.
AUTOSame as HOT, but the data is updated upon notification from the server, without invocation of the DDEADVISE event.
COLD, OFFTurns off any notification by the server, until any of the other three properties is invoked.
