   ---------------------------------------------------------------------------

unit Unit2;

interface

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

type
  TfrmLogin = class(TForm)
    Edit1: TEdit;
    Edit2: TEdit;
    Button1: TButton;
  private
    { Private declarations }
  public
    { Public declarations }
    class procedure GetLoginInfo (var Username, password : String);
  end;

var
  frmLogin: TfrmLogin;

implementation

{$R *.DFM}

{ TfrmLogin }

class procedure TfrmLogin.GetLoginInfo(var Username, password: String);
var
  tmp_form : TfrmLogin;
begin
  tmp_Form := TfrmLogin.Create(Application);
  with tmp_Form do
    begin
      if ShowModal = mrOK then
        begin
          UserName := Edit1.Text;
          Password := Edit2.text;
