I'm trying to write a Ruby extension to access some C++ drivers that are 
part of the project I'm working on. I could really use a simple Visual 
Studio example or walk-through on the basic process.

The code itself shouldn't be a problem, but I haven't been able to build 
and use even a simple example (e.g., 
http://www.rubygarden.org/ruby?WritingExtensionInCpp). 

Any pointers or advice would be most appreciated.
