LinkTest

LinkTest - DDE Command Tester is a free utility that allows you to test all WinWedge DDE commands or test DDE commands that can be sent to other programs.

To test any WinWedge DDE commands, the Wedge must be running and activated in either "Test Mode", "Normal Mode", or "Virtual Instrument Mode". LinkTest provides two text boxes where you specify the Application Name and DDE Link Topic for the application that you want to send a DDE command to.
