Hi Brian!
Agree that one shouldn't reinvent the wheel. I also find the API rather complex and I havn't had need to use much of it.
I would expect you should stand a better chance in pure
VB/C++ communities to find explanations of/links to the API.
I'm not sure that I have any specific links but I'll have a look when I get home from work and post what I may find. I think I have some German, but the code is of cause universal.
