Obtener grupo de trabajo / Dominio de un PC - Delphi
Lenguaje de programación Borland Delphi



Este código obtiene el grupo de trabajo/dominio de un PC:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)

    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation
