I'm working in an aplication for a Smart Device that need to "talk" with a printer continuosly through the serial port. I'm trying to use the John Hint's sample code "Use P/Invoke to develop a .NET Base Class Library for Serial Device Communication" but I'm new with VC# and need some basic rules because I have a lot of compilation errors. Where should I create my inherited class? Thank you
