DDE - What is it?


  • OLE’s predecessor, Dynamic Data Exchange, is a method of dynamically moving data among applications in the Microsoft Win32 Application Programming Interface (API).


  • The DDE protocols send messages between applications that share data and use shared memory to exchange data.


  • Applications can use the DDE protocol for one-time data transfer and for continuous exchanges in which applications send updates to one another as new data become available.


  • Prior to OPC, hardware manufacturers that recognized the need for software connectivity to their hardware was limited in their ability to develop drivers—the choice was between DDE and a list of proprietary DDE derivatives. Selecting any of these had possible
    effects of limiting the user’s choice of software or preventing the acceptance of the hardware.


  • Due to OPC data exchange popularity, DDE is becoming less popular.
