Learning About DDE

DDE stands for dynamic data exchange. Like the other technologies discussed in this chapter (OLE, DCOM, COM, and ActiveX), DDE's primary purpose is to exchange data between applications. In fact, DDE was the first technology to automate the transfer of data between Windows applications. For users of Windows 3.x applications, DDE was usually the technology of choice for application-data-exchange.

An example of a typical DDE application might have been to integrate some data retrieved out of a database into a document in order to produce a sales report or an earnings report. In this application, Microsoft Word might be used to develop the document, and Word would use DDE to retrieve information from the application storing the data, perhaps a Microsoft Excel spreadsheet, a Microsoft Access database, or an in-house built application.
