when i try and compile using the hashing.h and cpp files i get link errors. ive even made a completely blank program and included hashing.h and still same link errors:
[code]

Debug/main.exe : fatal error LNK1120: 3 unresolved externals
Error executing link.exe.

main.exe - 4 error(s), 0 warning(s)

[/code]

Make sure you include "Version.lib"

(If you're using VC++ go to Project -> Settings [Alt + F7] -> Link)

aha!

Or you could write this in Hashing.cpp.
[code]
#pragma comment(lib, "version.lib")
[/code]
