Dynamic data exchange (DDE) is a powerful feature of the Microsoft Windows operating environment. DDE provides a protocol through which applications can exchange data of all sorts. DDE enables applications to form hot links with DDE servers and obtain data in real time. A hot link is a direct data feed from one application (a DDE server) to another (a DDE client). As the data changes at the server, the server sends the new information to the client to be processed. This version is the first release on CNET Download.com.
