Use Get-LoggedOnUsers Function without needing the whole appdeploymenttoolkit


I have been looking for a function that will display all sessions on a machine. The function provided within PSADT has everything i need however i want to make it a standalone function without having to dot source the toolkit since i need to use it outside of application deployment.

I can see the function itself refers to the CS file which has all the commands in it.

Any help is most appreciated

Normally I wouldn’t help for non-PSADT related stuff but since you are not a new user and I saw this coming from Reddit, why not this one time.

It’s not trivial but you might find a way to shrink it some more.
CAVEAT: Not tested.

#TODO: path to AppDeployToolkitMain.cs
[String]$appDeployCustomTypesSourceCode = '<path to>\AppDeployToolkitMain.cs'

#CAVEAT: If you need to change AppDeployToolkitMain.cs you'll need to change the class name or reboot. I don't think you can remove Types.
## Add the custom types required for the toolkit
If (-not ([Management.Automation.PSTypeName]'PSADT.UiAutomation').Type) {
 # Not sure if you need these other assemblies, uncomment if it fails.
 #   [String[]]$ReferencedAssemblies = 'System.Drawing', 'System.Windows.Forms', 'System.DirectoryServices'
 #   Add-Type -Path $appDeployCustomTypesSourceCode -ReferencedAssemblies $ReferencedAssemblies -IgnoreWarnings -ErrorAction 'Stop'
	Add-Type -Path $appDeployCustomTypesSourceCode -IgnoreWarnings -ErrorAction 'Stop'

#region Function Get-LoggedOnUser
Function Get-LoggedOnUser {
Get session details for all local and RDP logged on users.

Get session details for all local and RDP logged on users using Win32 APIs. Get the following session details:
    NTAccount, SID, UserName, DomainName, SessionId, SessionName, ConnectState, IsCurrentSession, IsConsoleSession, IsUserSession, IsActiveUserSession
    IsRdpSession, IsLocalAdmin, LogonTime, IdleTime, DisconnectTime, ClientName, ClientProtocolType, ClientDirectory, ClientBuildNumber


You cannot pipe objects to this function.


This function does not return any objects.
