Errormode

[jaswicki]

I am writing some code to do a WMI call and on machines with corrupted WMI it is erroring out. Is there a way to supress all errors like the errormode(@OFF) command in Winbatch so that I can capture and do my own error handling? The second line below is the one throwing the error. It works fine on a machine without WMI issues.

$objWMI = ObjGet("winmgmts:\\localhost\root\CIMV2")
$objItems = $objWMI.ExecQuery("SELECT * FROM Win32_SystemEnclosure", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly)

Since this is an Object you can use ObjEvent("AutoIt.Error", ... to catch the error.

Try some error checking.

$objWMI = ObjGet("winmgmts:\\localhost\root\CIMV2")
If IsObj($objWMI) Then
    $objItems = $objWMI.ExecQuery("SELECT * FROM Win32_SystemEnclosure", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly)
Else
    MsgBox(0, "Error", Unable to get the object")
EndIf

Also look in the Help file under Obj/Com reference, about 2/3 of the way down the page there is a good example of error handling.

EDIT: Another common problem with WMI is that the service is disabled. You should check for that as well and if it's disabled then enable it.

Thanks for the quick relpies!
