GetNumberFormat

The GetNumberFormat function formats a number string as a number string customized for a specified locale.

int GetNumberFormat(
  LCID Locale,                // locale for which string is to be formatted
  DWORD dwFlags,              // bit flag that controls the function's operation
  LPCTSTR lpValue,            // pointer to input number string
  CONST NUMBERFMT *lpFormat,  // pointer to a formatting information structure
  LPTSTR lpNumberStr,         // pointer to output buffer
  int cchNumber               // size of output buffer
);

static NUMBERFMT nFmt = { 0, 0, 3, ",", ".", 0 };
CString CMainFrame::GetNumberFormatFileSize(int nFileSize)
{
    TCHAR    szVal[32];
    TCHAR    szOut[32];
    CString  strReturn = _T("");
    wsprintf ( szVal,"%d",nFileSize/1000 );
    GetNumberFormat ( NULL, NULL, szVal, &nFmt, szOut, 32 );
    strReturn.Format ( "%sKB", szOut); 
    return strReturn;
}
