What I would do to get it working in borland c++ builder would be to first build a lib file using implib.exe under borland then by using the example atisp.h file under flip construct my own calls to the dlls. I did something similar to this when I build an applet for my logitech g15 keyboard lcd. It's been a long time since I did any programming in visaul basic. It use to be my main stay, but know I do everything in C,C++ or C#. After looking thru the source files, think there is enough info there to make it work in either vb6 or C++.
