Usage notes

To use the DDE Server functionality, the Service Manager Windows client must be started and a user should be logged in. DDE does not automatically start the server (as OLE does). The user must be logged in so that the environment is set up for the Service Manager user.

The DDE server can also handle DDE client transactions that perform:

  • Requests: Get the value of a named item and return it as a string
  • Pokes: Set the value of a named item
  • Executes: Ask the GUI to execute a transaction or set the focus to a named item

Use this functionality to script user interaction for common operations such as closing a record, which may require several fields to be filled in and several transactions to be made.
