Using DDE applications

progeCAD supports the DDE API, which allows you to execute progeCAD commands at the command line from an external application. progeCAD includes a sample command-line application that reads a script file and sends it to progeCAD for step-by-step execution.

To see a sample of DDE script execution

   1   Compile the source code of the DDESample project.

   2   Run progeCAD.

   3   Run the DDESample application with the sample script file that is included in the VC project.

progeCAD shows the results.
