Marco,
1. AFAIK, you cannot access routines inside an exe file from IDL. I suggest
that you put the routines/functions of question inside a dll, which you can
access from IDL and you can link you exe against. This way you only have one
set of routines.
2. You need to read on "Callable IDL" in the external developers guide. I
have never used it and the manual states something like that this is "hard",
but then again that is what I thought about DLM programming as well. And in
the end this wasn't so bad. However, you will not be able to use IDL debug
with any external code (wouldn't that be nice). So you are stuck with the
visual studio tools.
Cheers,
Haje
