Need some help in TCp

[Alexxander]

Hi all

i had posted before my first try (which was terrible) that must detect if the other side is online or not 

i'm trying to make a script that i can know if the other PC is connected to the internet or not

here's my second try

sender

TCPStartup()
$TCPcon = TCPConnect (@IPAddress1, 1234)
TCPSend($TCPcon, "on")

receiver 

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

GUICreate("Form1", 615, 227)
$Mainlist = GUICtrlCreateList("", -1,-1, 615, 1)
GUISetState()

TCPStartup()
$MainSocket = TCPListen(@IPAddress1, 1234)

While 1
    $TCPAccept = TCPAccept($MainSocket)
    $TCPRecv = TCPRecv($TCPAccept, 9999999)
    If $TCPRecv = "on" Then GUICtrlSetData($Mainlist , $TCPRecv)
    If $TCPRecv <> "on" Then GUICtrlSetData($Mainlist , "")
WEnd

this is working fine if i runned the sender code multiple times and fast enough i'll see it in my list

but i can't get it to always send the "on" message

i tried this 

TCPStartup()
$TCPcon = TCPConnect (@IPAddress1, 1234)
While 1
TCPSend($TCPcon, "on")
WEnd

but it doesn't worked

any ideas ?

TCPaccept() shouldn't be in your loop.

Thanks a lot buddy i really appreciate your help

your script is perfect

but may i ask a little question ?

when i remove the  _TCPAccept() from line 11 nothing change 

if i removed it wont affect anything right ?

and also the ContinueLoop is useless here  ?

please correct me if i'm wrong
