whats this puppy mean?? thing.obj : error LNK2001: unresolved external symbol "void __cdecl overwriteoptionpartb(void)" (?overwriteoptionpartb@@YAXXZ) i get this error when building.. it compiles it... no errors....but when it links this happens.. i have a function called overwriteoptionpartb

that means that the compiler can''t find the declaration for that function... it''s either in a .cpp file or a library that you need to include in your project.

probably thing.cpp
