Hello again,
After thinking about the previous discussed potential solution... it will be too complicated to work with an intermediate file, and it will not really cover our use case.
I need to explain a little bit more our application

We are writing a command-line program (.exe), which will be directly started from external programs, among other makefiles, without the need to open EA because :
1. EA takes too much time to start and
2. we can not install EA on any potential PC used in our company.
Moreover, our command-line program becomes several project-specific parameters which are dynamically prepared from the other programs, e.g. like a makefile does, depending of the project context, and its role is to extract specific data from the EAP-file - these dynamic generated parameters can not be known at modelling level in EA.
The command-line program just needs to read data - no model modification. It is intended to be used by System-integrators, System-testers and managers, which don't need (and don't know how) to use EA - this must remain transparent for such kind of people.
Only for the SW-Designers (who build the models), the command-line program will be integrated directly in EA via a menu / ribbon - so that they can check their modelling work output before releasing it.
Is there a way to use the EA-API without opening EA?
(I mean: not by using directly the ACCESS-DB queries)"
Regards,
Ankur
