====== Как получить информацию о локальных настройках системы ======

Delphi имеет функцию GetLocaleInfo, которая позволяет получать различную информацию о локальных настройках, таких как системный язык, символ валюты, количество десятичных знаков и т.д.

Далее приведена функция, которая возвращает значение в зависимости от параметра "flag":
<code delphi>
........ 
function TForm1.GetLocaleInformation(Flag: Integer): String; 
var 
  pcLCA:    Array[0..20] of Char; 
begin 
  if( GetLocaleInfo(LOCALE_SYSTEM_DEFAULT,Flag,pcLCA,19) <= 0 ) then begin 
    pcLCA[0] := #0; 
  end; 
  Result := pcLCA; 
end; 
........ 
</code>

Пример использования функции:
<code delphi>
........ 
procedure TForm1.Button1Click(Sender: TObject); 
begin 
  ShowMessage(GetLocaleInformation(LOCALE_SENGLANGUAGE)); 
end; 
........ 
</code>
"Flag" может содержать следующее значение (если посмотреть в Windows.pas):
