Using a C++ DLL in a Visual Basic 6 project

This week I have had to make a VB6 project interface with a 3rd party API packaged as a DLL and written in C++. Specificly, I am working on interfacing Embtrak, the leading embroidery order management software to Veristitch. I've learned several things along the way, some of them not well-documented on the Internet, as far as I can tell. Thanks to Sid Kaspar and RKerr on the microsoft.public.vb.general.discussion group for their part in helping me sort this out.
