Hello,
I am using VS.net 2003 and trying to build a very simple console c++
application. But got the
Console error LNK2020: unresolved token (0A00000D) MyString.__dtor
Console fatal error LNK1120: 1 unresolved externals

I have 3 files, one is Console.cpp and the other two are MyString.h and
MyString.cpp.

Anyone Can help me out?
Thanks a lot.
