Handling events with PowerShell?

Question

How can you handle events thrown by .NET object using PowerShell v2? Can someone point me to a simple code sample?

Answer 1

Look at the docs on the Register-ObjectEvent cmdlet. Be sure to use the -full parameter. It has some good examples of usage including this one:

$timer = New-Object Timers.Timer
$timer.Interval = 500
$timer.Start()
$job = Register-ObjectEvent -inputObject $timer -eventName Elapsed `
       -sourceIdentifier Timer.Random `
       -Action {$random = Get-Random -Min 0 -Max 100; $random}
Receive-Job $job
