Windows DDE Support

Description of Windows® DDE support.

Important: This feature is deprecated, its use is discouraged although not prohibited.

Dynamic Data Exchange (DDE) is a form of inter-process communication implemented by Microsoft™ for Windows platforms. DDE uses shared memory to exchange data between applications. Applications can use DDE for one-time data transfers and for ongoing exchanges in applications that send updates to one another as new data becomes available.

Please refer to your Microsoft documentation for DDE compatibility between existing versions. As an example, DDE commands were changed between Office 97 and Office 98.

We provide a DDE interface as a Front-End Extension: WinDDE.DLL.

Note: The front calls using Microsoft DDE/COM/Mail technologies are deprecated. To manipulate Microsoft Office documents, use freeware alternatives such as the Apache POI Java library. For an example, see Java Interface: Example 2.
