Because add-ins can only be programmed in C++, C# and VB.NET, I programmed one in C# as a work around for this limitation. The add-in monitors the PDM events, executes additional programs/scripts if required and provides them parameters that can only be read by the add-in when the event is fired. This makes it possible to execute further actions in any language, e.g. VBA, VBS, Autohotkey, etc. After finishing the programs/scripts, the returned ERRORLEVEL is evaluated by the add-in. If an error occurs, the process e.g. in PreEvents can be cancelled. I developed this add-in because I did not want to accept this limitation of programming languages.
What I want to say, you can solve almost every problem via API. Ask colleagues what improvements they would like to have. I think there will be some suggestions.
