Program and help file download (current version is 0.8.78): Controlling Lynx6
Extract the .7z archive using 7-Zip.
Errors when trying to run? You might be missing some OCX, DLL, or TLB files the program needs, so...
OCX, DLL, TLB Files download: Controlling Lynx6 Support Files
Extract the OCX files to the same folder as where you extracted the program to.
Then when you run the program it should be OK.
Source code download: Controlling Lynx6 Source
As I said, the full source code is available. It should help you understand controlling the Lynx6 in many ways, and also MCI (for playing the music).
The entire thing is commented so much that if you took the comments out, there would probably only be 2 or 3 lines of code left. In fact, it turns into more of a novel than a program at points... it was not exactly intended to be released as it is now.
