Question

这两天我开始编写一些使用Delphi XE5 ping其他设备的代码。令我高兴的是，我发现有一个名为IcmpClient的组件可用于ping。这是代码，主要来自一些网络资源。

unit main;

interface

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

type
  TfrmPing = class(TForm)
    edtHost: TEdit;
    btnPing: TButton;
    ICMP: TIdIcmpClient;
    Label1: TLabel;
    Panel1: TPanel;
    spnPing: TSpinEdit;
    lstReplies: TListBox;
    procedure btnPingClick(Sender: TObject);
    procedure ICMPReply(ASender: TComponent; const ReplyStatus: TReplyStatus);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  frmPing: TfrmPing;

implementation

{$R *.dfm}

procedure TfrmPing.btnPingClick(Sender: TObject);
var
  i: integer;
begin
  ICMP.OnReply := ICMPReply;
  ICMP.ReceiveTimeout := 1000;
  btnPing.Enabled := False; try
    ICMP.Host := edtHost.Text;
    for i := 1 to spnPing.Value do begin
      ICMP.Ping;
      Application.ProcessMessages;
    end;
  finally btnPing.Enabled := True; end;
end;


procedure TfrmPing.ICMPReply(ASender: TComponent; const ReplyStatus: TReplyStatus);
var
  sTime: string;
begin
  // TODO: check for error on ping reply (ReplyStatus.MsgType?)
  if (ReplyStatus.MsRoundTripTime = 0) then
    sTime := '<1'
  else
    sTime := '=';

  lstReplies.Items.Add(Format('%d bytes from %s: icmp_seq=%d ttl=%d time%s%d ms',
    [ReplyStatus.BytesReceived,
    ReplyStatus.FromIpAddress,
    ReplyStatus.SequenceId,
    ReplyStatus.TimeToLive,
    sTime,
    ReplyStatus.MsRoundTripTime]));
end;

end.

在解决了错误＃10013的问题后（通过授予管理员权限），我遇到了第二个错误＃10040。

根据这里的一篇文章，有人说在从xe3升级到xe4后发生了，而Remy Lebeau说它正在修复。但几个月后，我们仍然遇到了XE5的错误。

我应该放弃Indy 10并寻找PING的其他方式，还是等待修复？
