[HELP] Zeitschleife

[JackTheRipper]

Hey,

Ich bin es mal wieder. Sorry das ich euhc mit meinen NewBee Fragen stresse

Also ich bin gerade am Proggen eines Programms das alle 30 Min ein Ping raussendet und
das in einem Memo rausgibt. Doch wie bau ich eine Zeitschleife hab schon die suche benutzt
und nix gefunden. Google hatte auch seine Probleme.

Delphi-Quellcode:

unit Superping;

interface

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

type
  TForm1 = class(TForm)
    Button1: TButton;
    Memo1: TMemo;
    Button2: TButton;
    Button3: TButton;
    Button4: TButton;
    Edit1: TEdit;
    Label1: TLabel;
    Label2: TLabel;
    Edit2: TEdit;
    Panel1: TPanel;
    Panel2: TPanel;
    procedure Button1Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
    procedure Button4Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}
