As I understand it, one must use the .dll netload in order to make use of the .NET functions available in AutoCAD... as per the original author's question, is it possible to configure a script or something that does the following?
1) Opens AutoCAD
2) Performs the appropriate netload (perhaps not necessary if in the Registry, as auto-load)
3) Calls the appropriate command in the .DLL to start your application...
Thanks!
