Microsoft Windows provides several methods for transferring data between applications. One way to transfer data is to use Windows dynamic data exchange (DDE). DDE is a message protocol for data exchange between Windows programs. It allows software developers to design applications that share data and thereby provide the user with a more integrated Windows environment.
For complete information about DDE, see the documentation for the Microsoft Windows Software Development Kit (SDK). This appendix describes the DDE formats that Microsoft Excel versions 5.0 and later support, and provides detailed information about the high-performance XlTable DDE format.
