UDP crash test

[yair]

im trying to setup a simple crash detector.

my software will send an int every few seconds via udp socket

autoit3 should run in loop and trip on failed transmition.

i tried doing it like so

but am getting a brain freeze.

; Start The UDP Services
;==============================================
UDPStartup()
; Register the cleanup function.
OnAutoItExitRegister("Cleanup")
; Bind to a SOCKET
;==============================================
$socket = UDPBind("127.0.0.1", 65532)
If @error <> 0 Then Exit
While 1
$data=""
    $data = UDPRecv($socket, 50)
$msg="stop"
;my software send sa "3" and it apears as this...
    If $data == "0x696E74002C69000000000003" Then
        $msg="continue"
    EndIf
    sleep(1000)
if $msg == "stop" Then ExitLoop
WEnd
MsgBox("error","",1)
Func Cleanup()
    UDPCloseSocket($socket)
    UDPShutdown()
EndFunc

any help?

Probably you should wait to be sure you get some data...

what about something like this?

; Start The UDP Services
;==============================================
UDPStartup()
; Register the cleanup function.
OnAutoItExitRegister("Cleanup")
; Bind to a SOCKET
;==============================================
$socket = UDPBind("127.0.0.1", 65532)
If @error <> 0 Then Exit
While 1
    $data=""
    $data = UDPRecv($socket, 50)
    If $data <> "" Then ;wait until we get some data
        ;my software send as "3" and it apears as this...
        If $data <> "0x696E74002C69000000000003" Then
            ExitLoop ;if not expected data exit
        EndIf
    EndIf
    sleep(1000)
WEnd
MsgBox("error","",1)
Func Cleanup()
    UDPCloseSocket($socket)
    UDPShutdown()
EndFunc
