tcp connection, identifier, string definition

[qwertylol]

If I connect multiple clients to the same port on the sever side of au3 codes,

do I identify between the clients with the data they send?

the data I send is stored in a variable beforehand right? and it has to be a string?

is the string created with function_string?

$var = String (hello world! this is alpha!)

TCPSend ( mainsocket, $var )

is this right?

also,

what should I do if I want au3 to connect to a domain name, like google, and send stuff to the search window and click search?

thank you !

thank you !

this might give you hints ....

#include <IE.au3>

_GoogleSearch("autoit beta")

Func _GoogleSearch($sString)
    $sString = StringReplace($sString, " ", "+")
    ShellExecute("www.google.com/search?q=" & $sString) 
EndFunc

There can be multiple sockets on the same port, each time you use tcpconnect() it shoudl give you a unique one.

does it mean that the tcp functions themselves grants no way where the connection it from, and I have to find out what my ip is and include it in my "data" to the server, and vice versa,

also, I have to start a listening socket on both side to talk to each other right ?

humm don't quite understand you... but i'll say yes. Have you read the sample in the help file yet? You may find this snippet helpfull-

Func SocketToIP($SHOCKET)
    Local $sockaddr = DLLStructCreate("short;ushort;uint;char[8]")

    Local $aRet = DLLCall("Ws2_32.dll","int","getpeername","int",$SHOCKET, _
            "ptr",DLLStructGetPtr($sockaddr),"int_ptr",DLLStructGetSize($sockaddr))
    If Not @error And $aRet[0] = 0 Then
        $aRet = DLLCall("Ws2_32.dll","str","inet_ntoa","int",DLLStructGetData($sockaddr,3))
        If Not @error Then $aRet = $aRet[0]
    Else
        $aRet = 0
    EndIf

    $sockaddr = 0

    Return $aRet
EndFunc

Which returns the IP adress from the socket

um, what is a structure?

That is irrelevant for now. Don't look inside the function, only learn how to use it. Edited April 16, 2007 by Manadar
