Hi,
I've been following this guide http://multyremotes.com/DC-motor-control-in-VC.htm making a program that will control a DC 12v motor through the computers LPT port.
But the problem is that when I try to build it I get 28 errors.
I really need to finish this!
If anyone got a spare minute to look through the code I would be really happy!
