Hello, I have a problem, I downloaded example of TCP Server and Client, but client doesn't work, It shows TCPConnect 10060 error (timeout), I tried to turn on two servers, I think server work, because one server show 10048 error(Address already in use) I don't know why it doesn't work, I edited that script, but it doesn't work still. I tried TCPConnect and TCPAccept from AutoIt3\Examples\Helpfile, but TCPConnect shows error 10060(timeout)... Anybody knows how to fix it? Thanks ; SERVER #include <Array.au3> TCPStartup() Dim $Socket_Data[1] $Socket_Data[0] = 0 $Listen = TCPListen(@IPAddress1, 1018, 500) If @error Then ConsoleWrite('!-->['&@Hour&":"&@MIN&":"&@SEC&'] TCPListen error. ( ' & @error & ' )' & @CRLF) Exit EndIf While 1 For $x = $Socket_Data[0] To 1 Step -1 $Recv = TCPRecv($Socket_Data[$x], 1000000) If $Recv Then MsgBox(0, 'Client Number ' & $x & ' with connected socket identifier ' & $Socket_Data[$x], "["&@Hour&":"&@MIN&":"&@SEC&"]"&' Recived msg from Client: ' & @CRLF & $Recv, 5) TCPSend($Socket_Data[$x], 'bye') TCPCloseSocket($Socket_Data[$x]) _ArrayDelete($Socket_Data, $x) $Socket_Data[0] -= 1 EndIf Next _Accept() WEnd Func _Accept() Local $Accept = TCPAccept($Listen) If $Accept <> -1 Then _ArrayAdd($Socket_Data, $Accept) $Socket_Data[0] += 1 EndIf EndFunc ;==>_Accept exit; CLIENT $Connected = False TCPStartup() ; Start TCP. $timespentconnecting = TimerInit( ) Do $Socket = TCPConnect(@IPAddress1, 1018) ; Connect to server. $nERROR = @error ; TCPConnect @error.

I have created a function that I hope will validate an IP address sent to it. I have searched the site for one but I wasn't able to find one that was bullet-proof from all the ones I have run up against here. This one will not only validate that the values are in the right range, but will also tell you what Class the IP address falls under. It will check for the invalid number ranges, 0.xx.xx.xx or 127.xx.xx.xx for example, as well as for the reserved ranges above 239.xxx. I've seen a lot of attempts with RegEx but I didn't find one that would correctly validate that all 4 octets are within the valid IPv4 range, most will check to see if the values are above 255 or below 0 or contain anything that isn't a number, but that doesn't validate an IP address it just validates whether the numbers look right. This will spit back an error if there are any non-numeric characters in the string, or you send it an IP address with less than all 4 octets. Or if your IP address is outside the valid class A-D ranges. Please beat this function up as much as you can so that I can tell if I missed something, and if there's anyone out there that understands the IPv4 standards that this function misses, please let me know so I can fix it. Thanks for looking.
