Re: How to add thousand separators

Here's a function I wrote that takes the locale into consideration. You
do have to make sure the buffer is as big as nSize)

e.g.,
TCHAR buf[30];
m_cTrackList.SetItemText(nItem,2,Comma(track.startBlock, buf, 29));

PTCHAR Comma(LONGLONG value,PTCHAR bufout, UINT nSize)
{
    TCHAR bufin[30]; // 30 digits is a really big number
    TCHAR dsep[5], tsep[5];
    NUMBERFMT fmt;
    fmt.NumDigits = 0;
    ::GetLocaleInfo(LOCALE_USER_DEFAULT,LOCALE_ILZERO,bufin,2);
    fmt.LeadingZero = _ttoi(bufin);
    fmt.Grouping = 3;
    ::GetLocaleInfo(LOCALE_USER_DEFAULT,LOCALE_SDECIMAL,dsep,4);
    fmt.lpDecimalSep = dsep;
    ::GetLocaleInfo(LOCALE_USER_DEFAULT,LOCALE_STHOUSAND ,tsep,4);
    fmt.lpThousandSep = tsep;
    ::GetLocaleInfo(LOCALE_USER_DEFAULT,LOCALE_INEGNUMBER ,bufin,2);
    fmt.NegativeOrder = _ttoi(bufin);

    _stprintf_s(bufin, _T("%I64d"), value);
    ::GetNumberFormat(LOCALE_USER_DEFAULT, 0, bufin, &fmt, bufout, nSize);
    return bufout;
}
