Hot Link

When operating a hot link DDE conversation, as soon as the data changes in the server application, it is automatically sent to the client. The client requests the data only once: when it initially establishes a link to the server.

A hot link is used when you constantly want updated information from the server application. The following PowerBuilder functions are related to the hot link:
StartHotLink(location, appl_name, topic)
GetDataDDEOrigin(which_appl, what_topic, what_loc)
GetDataDDE(string)
RespondRemote(Boolean)
StopHotLink(location, appl_name, topic)
