Recommended Posts

Ontosy

I have this code:

    do
        $a=OnLine3()
        msgbox(0, "aaaa", $a)
    until $a=0
i'm offline and receive:

@error=4

i go online and every receive

@error=4

i stop script and restart i receive

@error=0

Do it is a bug? how to solve?

To less script info also you want to Ping something right? °-° just do

$IP = 'SomeIPorDomain.com'
$Ping = Ping($IP)
Consolewrite($IP & ' has been pinged your ms to ' & $IP & ' is ' & $Ping & 'ms')

Sorry I was writing the precise example.

I go offline and execute:

do
        Ping("www.google.com", 250)
        $a=@error
        msgbox(0, "aaaa", $a)
    until $a=0

msgbox wait ping and return 4

then i go online and click ok in the previous msgbox

msgbox not wait ping and return every 4 instead of 0.

it is as if the ping is cached and it is not rerun.

think you just need to slow your loop, this works

Do
$ret = ping("www.google.com")
$err = @Error
$out = $err > 0 ?  msgbox(0, '' , "Error #" & $err & "- still down   :( ") : msgbox(0, '' , $ret & "ms")
sleep(1000)
Until $err = 0

Is not a sleep problem, msgbox self create a sleep.

If you try also your example have same defect.

Go offline

execute your script and return error

Go online

click msgbox, again it return error

Mine does not return an error when i go back online.  It returns the round trip time and exits the loop.

Are you waiting long enough to make sure your computer is actually online? It usually takes at least a few seconds after plugging the network cable in, or reenabling a network adapter before you're actually online.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Please do not create a bug report until we have made a conclusion here.

Please run this script and do your "go offline" and back On line and tell me how the RC and @Error changed.

While 1
    $rc=Ping("www.google.com")
    ConsoleWrite('@@ Debug : $rc = ' & $rc & '   Error code: ' & @error & @CRLF) ;### Debug Console
    Sleep(1000)
WEnd

My mod is only trying to test if UDP is working fine or not, as Ping is using ICMP.
I was hope that this small change:

_NTP_GetTime_PL()
    If @error Then
        ConsoleWrite('UDPOpen also have issue' & @CRLF)
    Else
        ConsoleWrite('UDPOpen works correctly' & @CRLF)
    EndIf

is not so big.

Ok, i now have timed better.

The script work but after 34 seconds.

Instead via dos ping it is instantaneous, when just go online.

Please be exact. The script does work all the time but tell me exactly what the returned status is as I requested, before, directly after you disable, and the Enable and then after 34 seconds. ;)
