<H2>Description</H2>

This class encapsulates the basic logic behind a service application. It
takes care of installing, removing and starting a service as a console
application.

I'm just a simple little NT programmer. Most of the work I do is remote controlling equipment in real time. I started out using Windows 3.0. Then came 3.1 and then NT. I started using NT but unfortunately, Microsoft didn't. I started using MFC but unfortunately, Microsoft didn't (and still doesn't) put any real support for NT into MFC so I wrote a bunch of C++ classes to make my life easier. Like all class libraries, mine grew. Now I'm giving it away, I call it Win32 Foundation Classes.
