Using DDE—Dynamic Data Exchange


Dynamic data exchange (DDE) is a method of exchanging data between multiple applications. One application sends data to a memory location that other applications access. A DDE application can function as a "client" that generally requests data or a "server" that generally provides data. DADiSP operates as both a DDE client and server. Although the functionality of DDE has largely been replaced by ActiveX, DDE still represents a useful technology for transferring data between applications.


When DADiSP acts as a DDE client, you can use DADiSP's built in DDE functions to:



Because DADiSP is also a DDE server, other applications can perform or request the same actions of DADiSP.
