I did another search for an older version of the Microsoft Platform SDK that has documentation on those functions. Microsoft has a link to a company that still has CDs containing earlier versions that I might be able for only the cost of shipping, (The current oldest one they offer themselves requires at least Windows 2000) . We'll see whether its useful.
In the meantime, I'm using the same compiler I used in school, but it had a number of visual components I could drag and drop onto a form. (I've never liked the drag-and-drop style of programming), and I couldn't find those components. So I went digging through the help files, and after a bunch of trial and error, found how to tell my compiler to use them, so I'm a bit happier about that.
