Re: Converting Language IDs

Yes. You should use EnumSystemLocales and in the callback procedure do
GetLocaleInfo(...) with LOCALE_SABBREVLANGNAME option to get all available
abbreviations until you 'll get the desired one.
Note, however, that this EnumSystemLocales API was very poor designed (it
doesn't have any User defined parameter to pass in) so you will, probably,
need to use some global/static variables...
I did it something like:

class CMyLocaleInfo
{
public:
  CString GetAbbreviationFromLocaleID(DWORD localeID);
.....
 CMyLocaleInfo();
 virtual ~CMyLocaleInfo();

private:
 static BOOL CALLBACK EnumLocalesProcAbbr(LPTSTR lpLocaleString);
 static CString s_strAbbrev;
 static DWORD s_localeID;
};
........

DWORD CMyLocaleInfo::s_localeID = 0;
CString CMyLocaleInfo::s_strAbbrev = _T("");

CString CMyLocaleInfo::GetAbbreviationFromLocaleID(DWORD localeID)
{
 CString strAbbrev;
 int nChar = GetLocaleInfo(localeID, LOCALE_SABBREVLANGNAME, NULL, 0);
 if(nChar)
 {
  nChar = GetLocaleInfo(localeID, LOCALE_SABBREVLANGNAME,
strAbbrev.GetBuffer(nChar), nChar);
  strAbbrev.ReleaseBuffer();
 }
 if(nChar == 0)
 {
  // error
  CString strErr;
  DWORD dwErr = ::GetLastError();
  switch (dwErr)
  {
  case ERROR_INSUFFICIENT_BUFFER:
   strErr.Format(_T("Buffer = %ul"), nChar);
   break;
  case ERROR_INVALID_FLAGS :
   strErr.Format(_T("Flags = %ul"), LOCALE_SABBREVLANGNAME);
   break;
  case ERROR_INVALID_PARAMETER :
   strErr.Format(_T("Locale_ID = %ul"), localeID);
   break;
  default:
   ASSERT(0);
  }
  LPVOID lpMsgBuf;
  FormatMessage(
      FORMAT_MESSAGE_ALLOCATE_BUFFER |
      FORMAT_MESSAGE_FROM_SYSTEM |
      FORMAT_MESSAGE_IGNORE_INSERTS,
      NULL,
      dwErr,
      MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
      (LPTSTR) &lpMsgBuf,
      0,
      NULL );
  CString strMess = (LPTSTR) lpMsgBuf;
  // Free the buffer.
  LocalFree( lpMsgBuf );
  // add message with dll name:
  strMess += _T("\r\n\'GetLocaleInfo\':\r\n") + strErr;
  AfxMessageBox( strMess, MB_OK | MB_ICONEXCLAMATION );
 }
 return strAbbrev;
}

BOOL CALLBACK CMyLocaleInfo::EnumLocalesProcAbbr(LPTSTR lpLocaleString)
{
 LPTSTR lp;
 // get language abbreviation
 CString strAbbr;
 DWORD locID = _tcstoul(lpLocaleString, &lp, 16);
 int nChar = GetLocaleInfo(locID, LOCALE_SABBREVLANGNAME, NULL, 0);
 if(nChar)
 {
  nChar = GetLocaleInfo(locID, LOCALE_SABBREVLANGNAME,
strAbbr.GetBuffer(nChar), nChar);
  strAbbr.ReleaseBuffer();
 }
 if(nChar == 0)
 {
  // error
  CString strErr;
  DWORD dwErr = ::GetLastError();
  switch (dwErr)
  {
  case ERROR_INSUFFICIENT_BUFFER:
   strErr.Format(_T("Buffer = %ul"), nChar);
   break;
  case ERROR_INVALID_FLAGS :
   strErr.Format(_T("Flags = %ul"), LOCALE_SABBREVLANGNAME);
   break;
  case ERROR_INVALID_PARAMETER :
   strErr.Format(_T("Locale_ID = %ul"), locID);
   break;

  AfxMessageBox( strMess, MB_OK | MB_ICONEXCLAMATION );
