$image\bookshls.gif$ Using DDE transactions through OLE Automation: Overview

You can call DDE Requests, Executes, and Notifications through OLE Automation. While this is not true object-oriented programming, it does allow you to use virtually all the DDE API functionality through OLE Automation instead of having to use DDEML.

To use DDE transactions through OLE Automation:

1. Get the Imagenation.Application object from the registry.
