tcp recieve data from existing connection?

[random667]

Lets say i have a chat program connected to yahoo chat,

can i use TCPRecv to get the same data the chat program is recieving?

i have been trying with this code, but doesnt seem to work.

;CLIENT!!!!!!!! Start SERVER First... dummy!!
#include <GUIConstants.au3>

; Start The TCP Services
;==============================================
TCPStartUp()

; Connect to a Listening "SOCKET"
;==============================================
$socket = TCPConnect( "216.155.193.142", "5050")
If $socket = -1 Then Exit

; Create a GUI for chatting
;==============================================
$GOOEY = GUICreate("my client - Server Connected",350,200)
$edit = GUICtrlCreateEdit("",10,40,330,150,$WS_DISABLED)
$input = GUICtrlCreateInput("",10,10,250,20)
$butt = GUICtrlCreateButton("Send",260,10,80,20,$BS_DEFPUSHBUTTON)
GUISetState()

$x = 0
Do
      $recv = TCPRecv($socket, 512 )
    GUICtrlSetData("Edit1", $recv)
    Until $x=1

Im listening!

GUICtrlSetData("Edit1", $recv)

What's this supposed to do? Is there an "Edit1" available? Or are you trying to set the data of "$edit"

Umm,?

yea, there is an edit,

$edit = GUICtrlCreateEdit("",10,40,330,150,$WS_DISABLED)

and i am trying to fill it with the data that is coming into a chat client which is connected to:

"216.155.193.142", "5050"

maybe i can simplify the code:

TCPStartUp()
$socket = TCPConnect( "216.155.193.142", "5050")
$x = 0
Do
    $recv = TCPRecv($socket, 512 )
    MsgBox(0, "title",$recv)
Until $x=1

my question is: can i use these Tcp commands to intercept the data that is comming into another program?

Answer: NO.

No way, you cannot connect to an already connected socket because the OS (Windoze) relays the data to the process that "owns" the socket (did first connect to it). This can only be one process at a time. What you need is a packet sniffer, but I think this cannot be done with AutoIT. You might be able to use WinPcpa, a packet capture library for Windows. See this link: WinPcap. You would have to DllCall some functions provided by packet.dll. But this is far beyond simple scripting....

EDIT: Just found this... This might help using WinPcap with AutoIT and VBScript... http://www.beesync.com/packetx/

There is also VBS sample code. BUT, even then, still a long way to go ...
