Question

I try to convert the last char of a CString to int using CString::GetAt() and _tstoi() but the compiler returns me error C2065: '_tstoi' : undeclared identifier. I guess i have to include a header file, i’ve tried #include "tchar.h" with no succes.

    CString str = "something2";
    int index = 0;

    if (!str.IsEmpty())
    {
        index = _tstoi((char*)str.GetAt(str.GetLength() - 1));
    }

EDIT: I use VC++ 6.0

Answer 1

This function under VC6 is _ttoi rather than _tstoi (still included in the header ‘tchar.h’)
