I want to have one int variable which is global to all the c++ files

1) in some header: extern int myvar;
2) in any *.cpp: int myvar;
3) in every *.cpp where you need to use myvar: #include "that_header's_name.h"

But this will become a local variable for every c++ file.

char* pszFoo = "C-Style Hello";
CString strFoo = "CString Hello";

InitInstance() {

    //...
