Hi ChipWarrior, welcome to the forum!
Quick question - have you done much Visual Studio programming or C or C++ programming before?
Under the project properties, linker, additional dependencies setting you need to add 'bassmod.lib' - simplest thing to do is to copy this .lib file from the bassmod20\c file into your project folder.
You also need to #include "bassmod.h" from that folder into your project, though I guess you've probably done that.
If you can't get that to work, I'm sure one of our members will be along in a sec with a quick sample code.
Have you got a demo in the works, or is this something for yourself?
Cheers,
Jim
