Powershell change/edit value of Object in Variable - powershell

I create variables in a ForEach loop using data collected from a CSV file like this:
New-Variable -Name $FlexVPN.'IP-adress' -Value (New-Object PSObject -Property #{
IP = $FlexVPN.'IP-adress'
Information = $FlexVPN.'Information'
Priority = $FlexVPN.'Priority'
RegisteredUp = $RegisteredUp
RegisteredDown = $RegisteredDown
ResponseTime = $Result = try{ Test-Connection -ComputerName $FlexVPN.'IP-adress' -Count $FlexVPN.'Priority' -ErrorAction Stop | Select ResponseTime} catch [System.Net.NetworkInformation.PingException] { $_.exception | PingFailed }})
What I'm then trying to do is to change the values of RegisteredUp and RegisteredDown depending of the respond of the ping.
I doesn't understand the New-Member stuff which I have tried but faild using.
Now I tried Set-Variable but I don´t get how to only change a Object within the Variable?
Set-Variable -Name $FlexVPN.'IP-adress' -Value (New-Object PSObject -Property #{RegisteredDown = "TESTING"})
I don´t get any errors neither it´s working.
To explain further.
If no respond on ping set Get-Date in RegisteredDown for that Variable.
If respond on ping ser Get-Date in RegisteredUp for that Variable.
I then use if/else to use the result somehow in the next version ;)
Edit
# Clear variables after loop
Remove-Variable * -force -erroraction silentlycontinue
function PingFailed {
# Add date and time when IP-address first didn't responded
$FlexVPN.RegisteredDown = 'AnotherTest'
# If only error should be printed
if($PrintError -eq 'Yes'){Write-Host -ForegroundColor Red $FlexVPN.'IP-adress' "," $FlexVPN.'Information'}

"Information" = $FlexVPN.'Information'
"Priority" = $FlexVPN.'Priority'
"Response time" = $Result.ResponseTime
"RegisteredDown" = 'Test'
}}
}
}
My Second try above works fine until I catch an exeption during ping and goes to my function PingFailed.
I want to run that function when an IP-address doesn´t respond and add Get-Date to RegisteredDown in those cases.
The error I recieve is:

"Priority" = $FlexVPN.'Priority'
"Response time" = $Result.ResponseTime
"RegisteredUp" = $FlexVPN.RegisteredUp
"RegisteredDown" = $FlexVPN.RegisteredDown
}
}
This code if I understand correctly reuse the same variable for each row in my CSV file.
I want to create one variable for each row (name them the IP-address) so that I can reuse the values stored for as long as the script i running.

Looks like you are overcomplicating things. You can create a new variable (object) like this
$FlexVPN = [PSCustomObject] #{
Information='Test'
}
Show the value of Information
$FlexVPN.Information
Change the value of Information
$FlexVPN.Information = 'AnotherTest'
Show the changed value of Information
$FlexVPN.Information
a valid use case for using new-variable would be if you dynamically create/use variables
Edit
your intent is not actual clear to me but following testbed might get you some new ideas to proceed from
# Mimick importing a csv
$FlexVPN = #'
IP-Adress,Information,Priority
1.1.1.1,FlexVPN,1
2.2.2.2,FlexVPN,2
'# | ConvertFrom-Csv
$FlexVPN.GetType() # Object[]
$FlexVPN[0].GetType() # PSCustomObject
($FlexVPN[0] | gm -MemberType NoteProperty).Count # 3 Noteproperties
$FlexVPN | % {
Add-Member -InputObject $_ -NotePropertyName 'RegisteredUp' -NotePropertyValue 1 -Force
Add-Member -InputObject $_ -NotePropertyName 'RegisteredDown' -NotePropertyValue 1 -Force
}
($FlexVPN[0] | gm -MemberType NoteProperty).Count # 5 Noteproperties

Managed what I wanted by doing like this:
# Clear variables after loop
Remove-Variable * -force -erroraction silentlycontinue
# Importing a csv
$FlexVPNList = Import-Csv -Path 'C:\Temp\Powershell scripts\PingIPEmail\PingIPEmail.csv' -Header 'IP', 'Information', 'Priority' -Delimiter ';' -Encoding UTF7
$FlexVPNList | % {
Add-Member -InputObject $_ -NotePropertyName 'RegisteredUp' -NotePropertyValue '' -Force
Add-Member -InputObject $_ -NotePropertyName 'RegisteredDown' -NotePropertyValue '' -Force
Add-Member -InputObject $_ -NotePropertyName 'ResponseTime' -NotePropertyValue '' -Force
}
Foreach($FlexVPN in $FlexVPNlist) {
$Ping = try{ Test-Connection -ComputerName $FlexVPN.IP -Count $FlexVPN.'Priority' -ErrorAction Stop | Select ResponseTime } catch [System.Net.NetworkInformation.PingException] { $_ }
if($Ping.ResponseTime -ge '0'){
$FlexVPN.RegisteredUp = Get-Date
$FlexVPN.ResponseTime = $Ping.ResponseTime
}
if($Ping.ResponseTime -eq $null){ $FlexVPN.RegisteredDown = Get-Date }
New-Variable -Name $FlexVPN.IP -Value (New-Object PSObject -Property #{
IP = $FlexVPN.IP
Information = $FlexVPN.Information
Priority = $FlexVPN.Priority
RegisteredUp = $FlexVPN.RegisteredUp
RegisteredDown = $FlexVPN.RegisteredDown
ResponseTime = $Ping.ResponseTime
})
[PSCustomObject]#{

"Priority" = $FlexVPN.Priority
"Response time" = $FlexVPN.ResponseTime
"RegisteredUp" = $FlexVPN.RegisteredUp

}
I can now do stuff If computer responded or not!

Trying to get all Teams with their owners, members and guest in a CSV using Powershell

I'm working on a script that allows me to fetch all of our Teams groups by their IDs and list the Id, Name, Owner(s), Member(s) and Guest(s).
The code works to a certain point, I get all the needed information, but it seems to be limiting it to 2 owners, 4 members and no guests...
When I run the code with adding it to a PSObject and simply do a write-host all the data is there, but I can't append it correctly to a CSV.
Code below, its either a limitation of the PSObject or I am doing something wrong/ missing something (hoping on the 2nd part ;) )
try

$host.Runspace.ThreadOptions = "ReuseThread"

Multi variable condition output

I'm seeing output issues within the 'Not Found' column, even when DisplayName is not null it's marking mailbox as 'Mailbox Not Found'. Seems ok for the first 5 output lines until until it hits the first 'Cloud' DisplayName then it fills every cell with 'Mailbox Not Found' in the 'Not Found' column.
****if (($mb1 -eq 'No Cloud Mailbox') -and ($mb2 -eq 'No Onprem Mailbox')) { $mb3 = 'Mailbox Not Found' }****
Am I missing something? Any help would be appreciated.

The code will become clearer if you introduce a few more variables so you are not re-using $mb1, $mb2 and $mb3.
The main problem with that is that once your variable $mb3 has been set to 'Mailbox Not Found', it will keep that value forever, since your last if does not state what it should become when the condition is not met.
Try this:
#================================
#Get date and read the users file

$date = Get-Date -format dd-MM-yy
$users = Get-Content D:\import\allrgs.txt

Hashtables and RunSpaces in powershell

I am having some problems with updating data in a list from the results of a hash table. I am 99% sure it is due to the lack of understanding of what i am doing.
I am generating a $list of servers from a CSV. the CSV contains Servername, domain, description, plus some additional blank columns for use later.
what i am trying to do in a nutshell: i need to pull the down processes from a list of remote servers. to do this i am throwing each server from the list and function into its own runspace, the Hashtable is updating as expected. But i can not update the original $list i have.
here is my code:
Function OpenFile ($FilePath) {
$OFDiag = new-object system.windows.forms.openfiledialog
$OFDiag.filter = 'CSV (*.csv) | *.csv'
$OFDiag.ShowDialog() | out-null
$OFDiag.filename
}
# Create Primary Variables
$FilePath = OpenFile
$list = (get-content $FilePath) -replace '\(',' -' #ALL Servers and Groups need to remove parenthesis
$list = $list -replace '\)' #finish up removing the parenthesis
$list = $list -replace ' Or WorkGroup'
$list = convertFrom-CSV $list | select 'Name', 'Computer_Description', 'Domain' #Need to convert the list into a CSV formatted table.
$list = $list | sort Name
$list | Add-Member -NotePropertyName 'LastReboot' -NotePropertyValue $null
$list | Add-Member -NotePropertyName 'LastDeployment' -NotePropertyValue $null
$list | Add-Member -NotePropertyName 'RebootStatus' -NotePropertyValue $null
$list | Add-Member -NotePropertyName 'DownProcess' -NotePropertyValue $null
$list | Add-Member -NotePropertyName 'EnabledStatus' -NotePropertyValue $null
$list | Add-Member -NotePropertyName 'RDP' -NotePropertyValue $null
$list | Add-Member -NotePropertyName 'SchedTask' -NotePropertyValue $null
$servers = $list | %{$_.Name} | sort #ALL SERVERS - ONLY Servernames
$ServProSel = {
#
# Checks for Running Services and Processes.
# This Makes a determination as to what service/process groups should be checked.
# The Information as to what processes to look for are sent to the ProSer_Check function
# information from there is sent to the ServerStatus Tab
#

# This is the actual function that is run on the remote system to check
# for processes and services.

$chkres += $chk
}
}

$chkres = "All Processes Up"}
Return $chkres
}

$grpName = $computer.'Computer_Description'
$cred = $(get-Variable "$Domain" -valueOnly)
#Create the powershell instance and supply the scriptblock with the other parameters
if(!$(Get-Variable "TEST_$domain" -ValueOnly)){
CredCheck $computer.name $cred
}
#SendToRunSpace $scriptBlock $computer $domain $global:hash
SendToRunSpace $ServProSel $computer $cred $grpName $global:hash
}
I am running this in PowerShell ISE so i can edit on the fly and test things. When i run this code i generate the $list and $hash items. Ultimately i would like to grab the value out of the $hash for the server and update the corresponding server information in the $list object.
or is there a better way to do this? is the Hashtable the only way to Synchronize data from the runspaces to the current process?

Assign local variable within scriptblock

I can't tell exactly what you want to do so I'll guess it's "pass a variable to scriptblock being invoked on a remote machine". If this is the case, you can either add parameters to the scriptblock or use the $using: qualifier as in:
$using:row.DNSChangeStatus = 'Change Needed'
Note that you can't "return" anything that way so you'd have to actually return the modified object from Invoke-Command.
$row = Invoke-Command -ComputerName $Computer.Name -ScriptBlock {
and add
$row
as the last line of the scriptblock.

Powershell script to see currently logged in users (domain and machine) + status (active, idle, away)

I am searching for a simple command to see logged on users on server.
I know this one :
Get-WmiObject -Class win32_computersystem
but this will not provide me the info I need.
It returns :
domain
Manufactureer
Model
Name (Machine name)
PrimaryOwnerName
TotalPhysicalMemory
I run Powershell 3.0 on a Windows 2012 server.
Also
Get-WmiObject Win32_LoggedOnUser -ComputerName $Computer | Select Antecedent -Unique
gives me not the exact answers I need.
I would love to see as well the idle time, or if they are active or away.
In search of this same solution, I found what I needed under a different question in stackoverflow:
Powershell-log-off-remote-session. The below one line will return a list of logged on users.
query user /server:$SERVER
Since we're in the PowerShell area, it's extra useful if we can return a proper PowerShell object ...
I personally like this method of parsing, for the terseness:
((quser) -replace '^>', '') -replace '\s{2,}', ',' | ConvertFrom-Csv
Note: this doesn't account for disconnected ("disc") users, but works well if you just want to get a quick list of users and don't care about the rest of the information. I just wanted a list and didn't care if they were currently disconnected.
If you do care about the rest of the data it's just a little more complex:

I take it a step farther and give you a very clean object on my blog.
I ended up making this into a module.
There's no "simple command" to do that. You can write a function, or take your choice of several that are available online in various code repositories. I use this:
function get-loggedonuser ($computername){
#mjolinor 3/17/10
$regexa = '.+Domain="(.+)",Name="(.+)"$'
$regexd = '.+LogonId="(\d+)"$'
$logontype = #{
"0"="Local System"
"2"="Interactive" #(Local logon)
"3"="Network" # (Remote logon)
"4"="Batch" # (Scheduled task)
"5"="Service" # (Service account logon)
"7"="Unlock" #(Screen saver)
"8"="NetworkCleartext" # (Cleartext network logon)
"9"="NewCredentials" #(RunAs using alternate credentials)
"10"="RemoteInteractive" #(RDP\TS\RemoteAssistance)
"11"="CachedInteractive" #(Local w\cached credentials)
}
$logon_sessions = #(gwmi win32_logonsession -ComputerName $computername)
$logon_users = #(gwmi win32_loggedonuser -ComputerName $computername)
$session_user = #{}
$logon_users |% {
$_.antecedent -match $regexa > $nul
$username = $matches[1] + "\" + $matches[2]
$_.dependent -match $regexd > $nul
$session = $matches[1]
$session_user[$session] += $username
}
$logon_sessions |%{
$starttime = [management.managementdatetimeconverter]::todatetime($_.starttime)
$loggedonuser = New-Object -TypeName psobject
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Session" -Value $_.logonid
$loggedonuser | Add-Member -MemberType NoteProperty -Name "User" -Value $session_user[$_.logonid]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Type" -Value $logontype[$_.logontype.tostring()]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Auth" -Value $_.authenticationpackage
$loggedonuser | Add-Member -MemberType NoteProperty -Name "StartTime" -Value $starttime
$loggedonuser
}
}
Maybe you can do something with
get-process -includeusername
If you want to find interactively logged on users, I found a great tip here :https://p0w3rsh3ll.wordpress.com/2012/02/03/get-logged-on-users/ (Win32_ComputerSystem did not help me)
$explorerprocesses = #(Get-WmiObject -Query "Select * FROM Win32_Process WHERE Name='explorer.exe'" -ErrorAction SilentlyContinue)
If ($explorerprocesses.Count -eq 0)
{
"No explorer process found / Nobody interactively logged on"
}
Else
{
ForEach ($i in $explorerprocesses)
{
$Username = $i.GetOwner().User
$Domain = $i.GetOwner().Domain
Write-Host "$Domain\$Username logged on since: $($i.ConvertToDateTime($i.CreationDate))"
}
}
Here is my Approach based on DarKalimHero's Suggestion by selecting only on Explorer.exe processes
Function Get-RdpSessions
{
param(
[string]$computername
)
$processinfo = Get-WmiObject -Query "select * from win32_process where name='explorer.exe'" -ComputerName $computername
$processinfo | ForEach-Object { $_.GetOwner().User } | Sort-Object -Unique | ForEach-Object { New-Object psobject -Property #{Computer=$computername;LoggedOn=$_} } | Select-Object Computer,LoggedOn
}
Another solution, also based on query user, but can handle variations in culture (as far as I can tell) and produces strongly-typed results (i.e. TimeSpan and DateTime values):
# Invoke "query user", it produces an output similar to this, but might be culture-dependant!
#
# USERNAME SESSIONNAME ID STATE IDLE TIME LOGON TIME

# pietje 4 Disc 49+01:01 4/14/2021 9:26 AM
$result = (&query 'user' | Out-String -Stream)
# Take the header text and insert a '|' before the start of every HEADER - although defined as inserting a bar after
# every 2 or more spaces, or after the space at the start.
$fencedHeader = $result[0] -replace '(^\s|\s{2,})', '$1|'
# Now get the positions of all bars.
$fenceIndexes = ($fencedHeader | Select-String '\|' -AllMatches).Matches.Index
$timeSpanFormats = [string[]]#("d\+hh\:mm", "h\:mm", "m")
$entries = foreach($line in $result | Select-Object -Skip 1)
{
# Insert bars on the same positions, and then split the line into separate parts using these bars.
$fenceIndexes | ForEach-Object { $line = $line.Insert($_, "|") }
$parts = $line -split '\|' | ForEach-Object { $_.Trim() }
# Parse each part as a strongly typed value, using the UI Culture if needed.
[PSCustomObject] #{
IsCurrent = ($parts[0] -eq '>');
Username = $parts[1];
SessionName = $parts[2];
Id = [int]($parts[3]);
State = $parts[4];
IdleTime = $(if($parts[5] -ne '.') { [TimeSpan]::ParseExact($parts[5], $timeSpanFormats, [CultureInfo]::CurrentUICulture) } else { [TimeSpan]::Zero });
LogonTime = [DateTime]::ParseExact($parts[6], "g", [CultureInfo]::CurrentUICulture);
}
}

Team!
I have pretty nice solution to get local session as [PSObject].
Function Get-LocalSession {
<#
.DESCRIPTION
Get local session. Pasre output of command - 'query session'.
#>
[OutputType([PSObject[]])]
[CmdletBinding()]
Param(
)
try {
#region functions
#endregion
$Result = #()
$Output = . query.exe 'session' | select-object -skip 1
#use regex to parse
$pattern = '^(?<This>.)(?<SessionName>[^\s]*)\s*(?<UserName>[a-z]\w*)?\s*(?<Id>[0-9]*)\s*(?<State>\w*)\s*((?<Type>\w*)\s*)?(?<Device>\w*)?'
foreach ( $line in $output ){
$match = [regex]::Matches( $line, $pattern )
if ( $match ){
$PSO = [PSCustomObject]#{
This = $match[0].groups['This'].Value
SessionName = $match[0].groups['SessionName'].Value
UserName = $match[0].groups['UserName'].Value
Id = $match[0].groups['Id'].Value
State = $match[0].groups['State'].Value
Type = $match[0].groups['Type'].Value
Device = $match[0].groups['Device'].Value
}
$Result += $PSO
}
Else {
write-host "Unable to process line [$line] in function [Get-LocalSession]!"
}
}
}
catch {
#Get-ErrorReporting -Trap $PSItem
write-host $PSItem
}
return $Result
}
#Run it
$SessionObject = Get-LocalSession
$SessionObject | format-table -autosize -property *
I have edited mjolinor script to remove duplicate records, and dummy account names such as system, network services,...etc
If you want to get all users
function get-loggedonuser ($computername){
$regexa = '.+Domain="(.+)",Name="(.+)"$'
$regexd = '.+LogonId="(\d+)"$'
$logontype = #{
"0"="Local System"

"8"="NetworkCleartext" # (Cleartext network logon)
"9"="NewCredentials" #(RunAs using alternate credentials)
"10"="RemoteInteractive" #(RDP\TS\RemoteAssistance)
"11"="CachedInteractive" #(Local w\cached credentials)
}
$logon_sessions = #(gwmi win32_logonsession -ComputerName $computername)
$logon_users = #(gwmi win32_loggedonuser -ComputerName $computername)
$session_user = #{}
$logon_users |% {
$_.antecedent -match $regexa > $nul
$username = $matches[1] + "\" + $matches[2]
$_.dependent -match $regexd > $nul
$session = $matches[1]
$session_user[$session] += $username
}
$logon_sessions |%{
$starttime = [management.managementdatetimeconverter]::todatetime($_.starttime)
if ($session_user[$_.logonid] -notin $loggedonuser.user -and $session_user[$_.logonid] -notlike "*$*"){
$loggedonuser = New-Object -TypeName psobject

$loggedonuser | Add-Member -MemberType NoteProperty -Name "Auth" -Value $_.authenticationpackage
$loggedonuser | Add-Member -MemberType NoteProperty -Name "StartTime" -Value $starttime
$loggedonuser
}
}
}
if you want to have only domain users
function get-loggedonuser ($computername){
$HST= hostname
$regexa = '.+Domain="(.+)",Name="(.+)"$'
$regexd = '.+LogonId="(\d+)"$'
$logontype = #{

"9"="NewCredentials" #(RunAs using alternate credentials)
"10"="RemoteInteractive" #(RDP\TS\RemoteAssistance)
"11"="CachedInteractive" #(Local w\cached credentials)
}
$logon_sessions = #(Get-WmiObject win32_logonsession -ComputerName $computername)
$logon_users = #(Get-WmiObject win32_loggedonuser -ComputerName $computername)
$session_user = #{}
$logon_users |ForEach-Object {
$_.antecedent -match $regexa > $nul
$username = $matches[1] + "\" + $matches[2]
$_.dependent -match $regexd > $nul
$session = $matches[1]
$session_user[$session] += $username
}
$logon_sessions |ForEach-Object{
if ($session_user[$_.logonid] -notin $loggedonuser.user -and $session_user[$_.logonid] -notlike "*$*" -and $session_user[$_.logonid] -notlike "*$HST*"){
$loggedonuser = New-Object -TypeName psobject
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Session" -Value $_.logonid
$loggedonuser | Add-Member -MemberType NoteProperty -Name "User" -Value $session_user[$_.logonid]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Type" -Value $logontype[$_.logontype.tostring()]

$loggedonuser | Add-Member -MemberType NoteProperty -Name "StartTime" -Value $starttime
$loggedonuser
}
}
}
This is what I just figured out and works out great!
Get-Process -IncludeUserName | Select-Object -Unique | Where-Object {$_.UserName -notlike 'NT AUTHORITY\SYSTEM' -and $_.UserName -notlike 'NT AUTHORITY\NETWORK SERVICE' -and $_.UserName -notlike 'NT AUTHORITY\LOCAL SERVICE'} | Format-Table -Wrap -AutoSize
