[twsocket] Bug with ICS and PING?
Having an interesting problem with TPing, and the replies under certain circumstances Here is my code I'm using: Ping1.Address := '10.110.12.1'; Memo1.Lines.Add(IntToStr(Ping1.Ping)); Memo1.Lines.Add(IntToStr(Ping1.ErrorCode)); Memo1.Lines.Add(IntToStr(Ping1.Reply.RTT)); If the address 10.110.12.1 Responds, I see the results 1, 0 and then the ms of the reply in my Memo1 - this is good. If the address 10.110.12.1 Does not respond, (DOS PING shows Request timed out) I see the results 0, 11010 and 0 in Memo1 - this is also good. If however you are trying to ping a device on the local subnet which is not there (DOS PING shows Destination host unreachable.) , the application returns 1, 0 and then the Reply.RTT shows the correct time it took to fail. It seems to me that this is a bug because the flag returned from ping indicates a success, and the ErrorCode also indicates no errors.

The success means the ICMP request packet has been sent. -- François Piette -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Bug with ICS and PING?
Are you suggesting that there is no bug? That's fine, but how does one differentiate then from a successful ping and an unsuccessful one (where CMD PING would reply Destination host unreachable.)

I've just answered my own question :) There is also TPing.Reply.Status - a zero is good, a non-zero is bad (seemingly). Thanks all.
