I doubt that you can do it in C but no worries, you can do it in C++. Check
out the example in the "external/ActiveX" directory in your IDL directory.

I checked the External Development Guide. The environment I am working
with is windows NT or XP. It seems that the simplest way to call C
from other program in Windows is "Including the IDLDrawWidget ActiveX
control in an application written in a language other than IDL." I
It is easy to do it in Visual Basic. VC++ also support ActiveX. But I
am not sure if C support ActiveX or not. Any one has some experience
on that?
Thanks,
Xiaoying

Yes, but probably not in the way that you want to. Callable IDL allows you
to call IDL from your C program but in a manner nothing like
"IDL_label_region(args);". Check out your options in the External
Development Guide, edg.pdf, found in IDL's help directory.
