TSGames Posted November 18, 2009 Share Posted November 18, 2009 Hello all, I'm using AutoIt to create a small Network application, based on TCP. I created a server and a client code, the server uses TCPListen("",65432,100) to accept connections. The Client uses TCPConnect("Ip-Address",65432) to connect to the server. Well, everything works fine if i try it on Windows XP. It also works if I start the server on a Windows XP Machine and connect from a Windows 7 pc. But I run into problems when I start the server on the Windows 7 pc and try to connect from XP. When Using the TCPConnect() command it always returns -1. I've disabled the firewall, run as administrator, but it doesn't seems to work for me. I also tried to disable the ip-v6 protocol on the Windows 7 machine, but still I don't get any connection. I also tried to compile the script with the latest Autoit Beta (3.3.1.5) - same error. I hope that someone can give me a hint. Thanks for any suggestions!

Richard Robertson Posted November 18, 2009 Share Posted November 18, 2009 Are you able to connect to Windows 7 from Windows 7? If not, then you may have another issue. Link to comment Share on other sites More sharing options...
TSGames Posted November 18, 2009 Author Share Posted November 18, 2009 Thanks for your fast answer! No, I also can't get any connection if i try to connect to "127.0.0.1" on the Windows 7 machine. It also returns -1 at TCPConnect() Regards TSGames Link to comment Share on other sites More sharing options...
Richard Robertson Posted November 18, 2009 Share Posted November 18, 2009 That's interesting. Have you tried a different port number to see if that's the problem? Like just try this pair of scripts. TCPStartup() $socket = TCPListen("", 12345, 10) While True $newsocket = TCPAccept($socket) If $newsocket != -1 Then MsgBox(0, "Connected", "Connected") Exit EndIf Sleep(100) WEnd TCPStartup() $socket = TCPConnect("", 12345) MsgBox(0, "", "Socket = " & $socket) Link to comment Share on other sites More sharing options...
TSGames Posted November 18, 2009 Author Share Posted November 18, 2009 (edited) Well, now I found out something interesting. If i create a Socket to Listen on the Windows 7 machine as in your example TCPListen("",12345,10) it returns -1 and sets @error to 1 (On the windows xp machine it returns an id and no error). So, if I enter an ip which is allowed to connect to, as 127.0.0.1, it returns an id and succeed. If I now connect using TCPConnect("127.0.0.1",12345) it works fine, but only if I actually connect from this ip. For example, if I call TCPConnect with the own LAN-IP, it doesn't work But how can I get it work to connect regardless of the client's ip? [EDIT] TCPListen(0,12345,10) seems to work. May should be documented in future versions? Thanks TSGames Edited November 18, 2009 by TSGames Link to comment Share on other sites More sharing options...
Richard Robertson Posted November 19, 2009 Share Posted November 19, 2009 0 might be better to use than the empty string. Or perhaps "0.0.0.0". I'm not sure what the problem is exactly, but using 0 seems to work for you so go with that. Link to comment Share on other sites More sharing options...
