I checked out the client-server API in the source code to use the compiler dll as suggested by adrpo.
However, this is way above my head and I guess I would have a hard time getting even a reference to these dll's from within VB.

Are there any easier ways to get interactive with the omc process ?

This thread talks about popen (python ?) and even named pipes:
https://openmodelica.org/forum/default- … -api#p3629

Is this an option to establish a fairly easy communication with the omc process?
How does this works with named pipes?

Could you give any rough example?

Hello Akram,

I'm also trying to get an interactive communication with the OMC compiler, from visual basic (VBA).

have you made any progress on this issue?
Could you send some results if available?


Best regards,

Yes, basically the client-server command API.
A similar functionality as OMShell but from within Visual Basic.

Can VB connect to an interactive OMC compiler via CORBA ?
Can the old interactive OMC (non CORBA) still be used in latest version of OM? If so, could I connect to this via sockets?

Is there documentation on how to interact directly with the compiler dll ?
Is there a COM wrapper for the compiler?

I found a similar project that connected Excel with Modelica, via Dymola.
I believe Dymola had a COM wrapper, so communication was easier...

Hi,

I was hoping to interact with OM compiler from within Excel, via visual basic.

I have a hard time getting interactive with OMC from within VB. (I would like to get compile information interactively).

I tried a few things:
1) Run OMC in interactive (only CORBA still seems to be available) and then communicate:
no joy, I can't find anything useful that allows CORBA use from within VB. The only thing that pops up is VbOrb, but nearly no documentation.

2) Run OMShell and trying to get it's standard output back: have tried to read StdOut directly (via WshShell.Exec.StdOut), redirect it to file, ... . doesn't work.


Is there a way to connect OMC with VB ?
Or alternatively, can I redirect all standard output and errors from OMshell to files?

I know the use of mos files, but OMC terminates when the mos is done, thereby losing all loaded classes. It would be very slow to always have to reload classes if I need some extra info on them.

Any help would be most appreciated.

Regards,

GeertD
