Stopping popups when script fails

[alanwsg 0]

I have a simple script that I use to control my netgear router ...

$oXML = ObjCreate("Microsoft.XMLHTTP")

$oXML.Open("GET", "http://192.168.0.1/setup.cgi?todo=" & $CmdLine[1] & "&wan=1", True, "admin", $CmdLine[2])

$oXML.Send

I call the script from a Java application and provide the 'todo' option & password as command line options.

When it works it's fine. But if it can't contact the router it popups-up a box saying something like "Script failed at Line -2" and then hangs waiting for user input.

Can I somehow prevent it from generating the popup and hanging and just return an error code instead?

Check out the section in the help file Obj/COM Reference. There is a COM Error Handling section that'd be worth a read for you. Also search this site.

One thing you can do is if you know you're failing due to connection you could do a 'ping' first.

Ping("192.168.0.1")
If NOT @error Then 
    $oXML = ObjCreate("Microsoft.XMLHTTP")
    $oXML.Open("GET", "http://192.168.0.1/setup.cgi?todo=" & $CmdLine[1] & "&wan=1", True, "admin", $CmdLine[2])
    $oXML.Send
EndIf

Thanks for that,

found a solution with a bit of cut&pasting from the Obj/COM Reference help section.
