Vista - i love powershell

today i wanted to an audit of a bunch of machines, to see what thye had
for their autostart


$ourerrors = new-Object system.Collections.ArrayList
$machines[1..200] | % {$comp = $_.ip; $_.ip } |
% {write-Host "working on $comP";trap {Write-host "**********error with
$comp" ; $ourerrors.Add($comp);continue } ;
[Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey("Localmachine",$comp
).opensubkey("software\microsoft\windows\currentversion\run").GetValueNames()
|
Select-Object (as comp, {$comp}, name , {$_} , val,
{[Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey("Localmachine",$mach
).opensubkey("software\microsoft\windows\currentversion\run").getvalue($_)})

}



works great.. learnt the best way to use trap is embed it in the scope
i am wanting to trap..

b.t.w if you are wanting my AS function..

#region setup AS function
function new-selectexpression
{
if ($args.count -eq 1) { $theargs = $args[0] } else {$theargs= $args }
if ($theargs.count -gt 1)
{
for($loop=0;$loop -lt ($theargs.count-1);$loop+=2)
{
@{Name=$theargs[$loop];Expression=$theargs[$loop+1]}
}
}
if (!($theargs.count % 2) -eq 0)
{@{Name=$inputs[$inputs.count-1];Expression= invoke-Expression "{}" } }
}
set-Alias as new-selectexpression
#endregion

Very interesting stuff, I like the idea of your 'as' function!
But I have one thing to add, I think there is a small bug in your script:
Those $inputs at the end, aren't they supposed to be $theargs instead, is
that correct?
I changed it the way I think it was meant and also added @( ) at several
places to correctly handle the case that there is only one element in the
parameter array.
The scriptblock that will be used in case that there is an odd number of
elements is now {$_}. I think this makes sense. Tell me what you think.

for($loop=0;$loop -lt (@($theargs).count-1);$loop+=2)
{
@{Name=@($theargs)[$loop];Expression=@($theargs)[$loop+1]}
}
}
if (!(@($theargs).count % 2) -eq 0)
{
@{Name=@($theargs)[@($theargs).count-1];Expression= invoke-Expression '{$_}'
} }
}
set-Alias as new-selectexpression
