DDE Support

Dynamic Data Exchange (DDE) is an old communication technology that allows DDE-enabled applications running under Microsoft Windows to dynamically exchange data with another via a defined link between them. The communication between such applications is referred to as a conversation.

The application that initiates the link, thereby starting the conversion, is called the Client. The application that responds to the client is called the Server. An application can act as the client in some conversions and as the server in others.

Uniface can act as both a DDE server and client. Uniface provides procedures to request, send, and execute DDE transactions using the activate ProcScript statement.

Note: Microsoft applications, such as Word and Excel, no longer support DDE. Consult your application documentation to see if it supports DDE.
