PowerShell and Events: Object Events. Continuing in my little series on PowerShell and different types of events, I will go into working with Object events and how you can use those with the Register-ObjectEvent cmdlet.
Because the parameters are the same as Register-EngineEvent, I won’t re-hash what each parameter does, instead check out this article to learn about some of the parameters that you can use for Support events and Forwarding events. An object event is a .Net object that not only has the usual Properties and Methods in the object, but also has another member called Event,which you can register a subscription on using Register-EngineEvent that will fire every single time that the event happens. With a wide range of .Net objects out there, there will certainly be something that has an event that you will find useful! Finding Events So how do I know if a .Net object has an event or events associated with it?
Save the object as a variable and use Get-Member Or use the .GetEvents() method from the object type itself. Powershell and writing files (how fast can you write to a file? ) - Guillaume Bordier's blog. Quick-Hits: Find currently logged on users. I was recently tasked with locating all servers on our network and query for users that were currently logged onto each server, either through a terminal session or logged on via console session.
This got me thinking of what ways are available to make this happen. When it was all said and done, I came up with 4 ways to do this. The first method is to use the Win32_ComputerSystem and grab the UserName property. The thing that you keep in mind with is that this will only return the user that is logged on using a console session, meaning that they are locally logged onto the machine, not logged on via remote desktop. The second method involves another WMI query that will work for both console sessions and remote sessions. The third method is made using the query sessions command line, which is available in Vista and above OS’s and on systems running Terminal Servers. Script Edit $ENV:Path in Powershell.
