IdICMPClient.Ping

[holger_barntrup]

Was mache ich hier falsch?

Delphi-Quellcode:

unit Unit3;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, IdIcmpClient, IdBaseComponent,
  IdComponent, IdRawBase, IdRawClient, Vcl.StdCtrls;

type
  TForm3 = class(TForm)
    Button1: TButton;
    IdIcmpClient: TIdIcmpClient;
    procedure IdIcmpClientReply(ASender: TComponent;
      const AReplyStatus: TReplyStatus);
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form3: TForm3;

implementation

{$R *.dfm}

procedure TForm3.Button1Click(Sender: TObject);
begin
   IdICMPClient.ReceiveTimeout := 5000; // Timeout 5000 ms
   //IdICMPClient.Host := edtAddress.Text;
   IdICMPClient.Host := '172.17.1.130';
   IdICMPClient.Ping();
end;

procedure TForm3.IdIcmpClientReply(ASender: TComponent;
  const AReplyStatus: TReplyStatus);
begin
   ShowMessage('Received ' + IntToStr(AReplyStatus.BytesReceived) + ' ' +
               'Bytes from ' + AReplyStatus.FromIpAddress + ' ' +
               'after ' + IntToStr(AReplyStatus.MsRoundTripTime) + ' ms.');
end;

end.

Ist ein Beispiel aus dem Netz. Ich erhalte dies zurück:
