atoi() will work as long as you are not using Unicode (or MBCS) strings. In this case, you need to use _wtoi()

Actually, use _ttoi and then the compiler will work out the UNICODE / Ansi string issues for you.

CString str = "123";
int i = _ttoi(str);

Even though the points have been awarded, heres how you do it using atoi().

int i = atoi(str.operator LPCTSTR());

*This works b/c LPCSTR is a "char*"
