Handle error

[kristoff]

Hi,

I'm fighting with the error return code :

What is the error code returned by

$IP = TCPNameToIP($mnger)

If the $mnger is resolved, @error return 0

If the $mnger is NOT resolved, @error return 0

So I would to trigger an action wheter the $mnger is resolved or not.

if $mnger is resolved then

ACTION1

else

action2

Endif

So I worte this, an of course I'm stuck

#include <C:\scripts\autoit\311-beta54\include\GUIConstants.au3>

$mnger = "ciao2323"

TCPStartUp()
$IP = TCPNameToIP($mnger)
msgbox(0,"NAME ",$IP)
msgbox(0,"ERROR CODE ",@error)

if @error = 0 Then
$var = Ping($mnger,250)
    If $var Then 
    msgbox (0,"","================  " & $mnger & " is resolved to " & $IP & "================") 
    msgbox (0,"","================   Rountrip was : " & $var & "================")
; Connect to a Listening "SOCKET"
;==============================================
    $socket = TCPConnect( $IP, 8080 )
        If $socket = -1 Then
        msgbox(0,"PORT"," GO FISHING PORT IS CLOSED ") 
        msgbox (0,""," =============== PORT  IS CLOSED ========== ")
        else 
        msgbox(0,"PORT"," PORT OPEN ") 
        msgbox (0,""," =============== PORT IS OPEN ..========== ")
        Endif
    Endif
else
msgbox (0,"","================  " & $mnger & " is NOT resolved ================") 
msgbox (0,"","================   PLEASE ENSURE " & $mnger & "NETBIOS NAME IS CORRECTLY RESOLVED ================") 
Endif
TCPShutdown ( )

Anyone to explain me clearly what's happened here

Many thanks in advance

Hi,

Found the trick, by testing the IP value, if value is "" ( null ) or not.

cheers

in fact the @error is reset by your msgbox(..) you need to save @error in a variable just after the call and test later on the variable
