(this question is also posted in students)

i would like to ping a client  ,i tryed to use tIdIcmpClient ,the code i
wrote is..
void __fastcall TForm1::Button1Click(TObject *Sender)
{
IdIcmpClient1->Host=Edit1->Text;
  IdIcmpClient1->Ping();
Memo1->Lines->Add(IdIcmpClient1->ReplyStatus.MsRoundTripTime);

}well when i execute the code many times fast i get a 0 value returned ,is
this normal?
also if i am behind a proxy server how can i declare which is the gateway
?beacause i can only ping the computers in my lan
network,noone in the internet...

i have tried to use the code provided above in a previous question  the code
is  following:
void __fastcall TForm1::Button1Click(TObject *Sender)
{


   IdIcmpClient1->Host=Edit1->Text;
   AnsiString s;
   IdIcmpClient1->Ping();
   switch(IdIcmpClient1->ReplyStatus.ReplyStatusType)
   {
      case rsEcho:
   s = "Reply from " + IdIcmpClient1->ReplyStatus.FromIpAddress
         + (": bytes=" +
AnsiString(IdIcmpClient1->ReplyStatus.BytesReceived))
         + (" time=" +
AnsiString(IdIcmpClient1->ReplyStatus.MsRoundTripTime) + "ms")
         + (" TTL=" + AnsiString(IdIcmpClient1->ReplyStatus.TimeToLive));
         ShowMessage(s);
      break;

      case rsError:
         ShowMessage("Request Error");
      break;

      case rsTimeOut:
         ShowMessage("Request Timed Out");
      break;

      case rsErrorUnreachable:
         ShowMessage("Host Unreachable");
      break;

      case rsErrorTTLExceeded:
         ShowMessage("TTL Exceeded");
      break;
   Memo1->Lines->Add(s);
   }
}

the problem is that i receive a 0 value in time if i execute many times fast
and most important that the time i get is very big..
what i mean is..if i ping a computer in my lan a receive from dos a <1ms
time in my program a value around 16ms and withe the code above around
>36..its very strange indeed .is there any explaination?
