Is this a DLL or a static library?

Did you add the LIB file to your project?

Routines that use the __cdecl calling convent (C calling convent) are 
decorated with a leading score.

The underscore is added for you. You should not add it yourself. If you 
do, the linker will look for __MyFunctionName.

Make sure you are linking with the library. Also, open the header file 
for the library and look for any evidence of something like

extern "C"

It should be there, since your error message said "Unresvoled external 
_MyFunctionName" instead of "Unresvoled external 
_MyFunction??23Name@@45". The latter ugly version is a mangled C++ name. 
Since the error didn't contain any goofy characters, other than the 
underscore, the linker must be looking for the plain C function 
MyFunctionName. My guess, is that you didn't tell in the name of the 
library to look in.
