>I could be wrong on this one, but odds are it was written in some flavor of C++.

I just emailed the vendor to find out what language...

If it ends up being C++, i will be puzzled. I couldn't get the DLL to work from VFP, so I wrote VB wrapper. When I asked them for the C declarations for the functions (they only gave VB declarations), the person I was dealing with wasn't able to give them to me (said he new C less than VFP).

Anyway, thanks for info,
