Looking for a PowerShelly way to set multiple values simultaneously on a multivalue ARS virtual attribute

You are most of the way there...

$strVaValue = @('value1' , 'value2' , 'value3')

$arSession = connect-qadservice -service <host> -proxy

foreach ($strVaValueItem in $strVaValue)

{

Set-QADComputer -Connection $ARSession -Identity $objComputer.DN -ObjectAttributes @{edsvaVirtualAttributeName=@{Append=@($strVaValueItem)}}

} # End of looping through $strVaValue list

Fixed the "foreach..." line...

Thanks for that JohnnyQ … that saved me from a self inflicted wound today ; )

from your example - the $strVaValue is set as an array - DOH! … it's not a string anymore.

I totally forgot about that collection of values - being an array inside the va.

so,  set my string value as an array and used the whole array inside objectAttributes .. and it worked! - in one pass without iteration … saving room in my change history database to boot.

Remembered - for the next time I fat finger my command line.

$myArray = @('value1','value2','value3')
Set-QADComputer -Connection $ARSession -Identity $objComputer.DN -objectAttributes @{edsvaVirtualAttribueName=@{Update=@($($myArray))}}

I used update here rather than append, because I wanted to erase the junk I had previously sent.

I didn't want to change your code too much but hey, regardless, I'm glad it worked out!

last question on the topic … Before I break something else on my testing box … is it your considered opinion that the same approach would work with this method - over the set-QADComputer commandlet way? 

$ADObj = [ADSI]("EDMS://" + $objComputer.properties.dstinguishedname)

$ADObj.putex(2,'edsvaVirtualAttributeName',@($($myarray)))

$ADObj.setinfo()

If you want to set using the array, your 2 should be a 3.

If you want to set using the array, your 2 should be a 3.

In this instance - I definitely needed the array - as my booboo replaced all existing values for a few hundred objects  with just the one add-on value.
oops.  I'd never considered this before - but RMAD doesn't include the ARS virtual attributes assigned to objects in AD ... What an enhancement that would be!
I was able to pull the prior value from change history - 'before' the after ... I wish the PS> commands would expose that too. Can I hear .. another enhancement?

Much appreciated Johnny Q! - thanks for sharing your knowledge.
