Thanks Filipe for answering,

Yes, for sure a dll would be a very good solution, but my knowledge of making and using dll:s is zero.
Maybe it's not so difficult, but can I take whatever C or C++ program and make a dll of it?
I have - of course a legal - MS VC6.

What I would like to put my efforts on, is using some existing GA/NN (or FSM) 3DGS code, and - if possible - not kill my last brain cells by trying to make a dll of some other peoples C-program. That was why I tried EvolutionNo9 in the first place.

More comments anyone?
