COM Objects while working in a background job - powershell

Trying to create a table in word and would like to speed up the process a bit, without jobs this works fine but it's just slow. When I run this script everything works fine except when the script gets to
$Table.Cell($x,<column>).Range.Text = <string>
It gives the error
You cannot call a method on a null-valued expression.
+ CategoryInfo : InvalidOperation: (Cell:String) [],
RuntimeException
+ FullyQualifiedErrorId : InvokeMethodOnNull
and when it gets to
$table = $doc.tables.item(1)
It gives the error
You cannot call a method on a null-valued expression.
+ CategoryInfo : InvalidOperation: (item:String) [], RuntimeException
+ FullyQualifiedErrorId : InvokeMethodOnNull
I'm guessing it has something to do with
[System.Runtime.InteropServices.Marshal]::GetActiveObject('Word.Application')
not taking all of the document's information...
Here's my code

EDIT: I am running this script on Posh V2 with Office Word 2007

This is a scoping issue. You aren't passing in all of the necessary objects (e.g. at least and most specifically, the Word COM object) into your scriptblock. PowerShell jobs actually create completely separate instances of the powershell process. Go ahead and check:
Start-Job -ScriptBlock { start-sleep -Seconds 20 }
Start-Job -ScriptBlock { start-sleep -Seconds 20 }

Coding with powershell

I'm new with powershell and i would like to use a loop to ping several Printers on my network.
My problem is : once i'm in the loop of pinging , i can't go out of the loop ...
I tried several things from google but without success ( start-stop , Timer ) . Does anybody have any idea?
Here is the code :
$BtnStartPingClicked = {
if ($LblFileSelectPing.Text -eq "*.txt") {
Add-Type -AssemblyName PresentationCore,PresentationFramework
$ButtonType = [System.Windows.MessageBoxButton]::OK
$MessageIcon = [System.Windows.MessageBoxImage]::Error
$MessageBody = "Please select a list of printer first"
$MessageTitle = "Error"
$Result = [System.Windows.MessageBox]::Show($MessageBody,$MessageTitle,$ButtonType,$MessageIcon)
Write-Host "Your choice is $Result"
}
else {
do {
$IPList = Get-Content ($LblFileSelectPing.Text)
$snmp = New-Object -ComObject olePrn.OleSNMP
$ping = New-Object System.Net.NetworkInformation.Ping
$i = 11
$j = 1
foreach ($Printer in $IPList) {
try {
$result = $ping.Send($Printer)
} catch {
$result = $null
}
if ($result.Status -eq 'Success') {
$((Get-Variable -name ("GBMachine"+$j+"Ping")).value).Visible = $True
$j++
test-Connection -ComputerName $Printer -Count 1 -Quiet
$printerip = $result.Address.ToString()
# OPEN SNMP CONNECTION TO PRINTER
$snmp.open($Printer, 'public', 2, 3000)
# MODEL
try {
$model = $snmp.Get('.1.3.6.1.2.1.25.3.2.1.3.1')
} catch {
$model = $null
}
# Serial
try {
$serial = $snmp.Get('.1.3.6.1.4.1.1602.1.2.1.8.1.3.1.1').toupper()
} catch {
$Dns = $null
}
# progress
$TBMonitoringPing.SelectionColor = "green"
$TBMonitoringPing.AppendText("$Printer is Pinging")
$TBMonitoringPing.AppendText("`n")
$mac = (arp -a $Printer | Select-String '([0-9a-f]{2}-){5}[0-9a-f]{2}').Matches.Value
# OPEN SNMP CONNECTION TO PRINTER
$((Get-Variable -name ('LblMach' + $i)).value).Text = "IP : $Printerip"
$i++
$((Get-Variable -name ('LblMach' + $i)).value).Text = "Model : $Model"
$i++
$((Get-Variable -name ('LblMach' + $i)).value).Text = "MAC : $mac"

Get-Content ($LblFileSelectPing.Text) | Where-Object {$_ -notmatch $Printer} | Set-Content ("C:\_canonsoftware\out.txt")
$i = $i+7
$snmp.Close()
Start-Sleep -milliseconds 1000 # Take a breather!
}
else {
$TBMonitoringPing.selectioncolor = "red"
$TBMonitoringPing.AppendText("$Printer not pinging")
$TBMonitoringPing.AppendText("`n")
Start-Sleep -milliseconds 1000 # Take a breather!
}
}
$LblFileSelectPing.Text = "C:\_canonsoftware\out.txt"
} until($infinity)
}
}
thanks for your answers...
1 - part of my object are indeed not declared in the code because they are in my other PS1 file....
2 - I do a do until infinity because i don't want to stop the code before i decide it...
3 - I didn't explain my problem correctly ( excuse my poor english ) ... i would like to be able to go out of the loop do until at the moment i click on a stop button ... but apprently the windows doens't respond while in the loop ... i have to stop the script with powershell ... which is annoying because i'd like to make an executable with it ... and not have to go out of my program ...
thank you for your ideas

Timestamp of finished Powershell task

I have a basic script, which will shutdown Windows services and generate a report about their shutdown processes. I also want to include two more columns into my output variable ($table), which will be timestamp values i.e. when shutdown tasks were launched and when they finished. I have no idea how to implement this into my report.
$processlist = #('SQLTELEMETRY$TESTDB', 'MSSQL$TESTDB', 'SQLWRITER')
$get = ''
$table = #{ }
$failed = 0
foreach ($proc in $processlist) {
stop-service -name $proc -force
}
#start-sleep -s 120
foreach ($proc in $processlist) {
$get = get-service $proc -Erroraction ignore
if ($get.Status -eq 'Running') {
$table += #{$proc = 'Running' }
}
else {
$table += #{$proc = 'Stopped' }
}
}
foreach ($value in $table.GetEnumerator()) {
if ($value.Value -eq 'Running') {
$failed += 1
}
}
if ($failed -gt 0) {
$err = 'FAILED'
}
else {
$err = 'SUCCESS'
}
$table.GetEnumerator() | Select-Object -Property Name, Value | export-csv appreport.csv -delimiter ";" -force -notypeinformation
(HTML part here...)
Instead of adding stuff into a Hashtable, I think it would be a lot easier to build an array of objects and write that as CSV file.
Something like this:
$serviceList = 'SQLTELEMETRY$TESTDB', 'MSSQL$TESTDB', 'SQLWRITER'
$maxAttempts = 10
# $result will become an array of PsCustomObjects you can easily pipe to Export-Csv
$result = foreach ($service in $serviceList) {
$shutStart = Get-Date
$svc = Get-Service -Name $service -ErrorAction SilentlyContinue
if ($svc) {
for ($attempt = 0; $attempt -lt $maxAttempts; $attempt++) {
$shutResult = 'Failed'
Start-Sleep -Milliseconds 100
$svc | Stop-Service -Force -ErrorAction SilentlyContinue
# test if the service has stopped. If so exit the loop
if (($svc | Get-Service).Status -eq 'Stopped') {
$shutResult = 'Success'
break
}
}
[PsCustomObject]#{
'ServiceName' = $svc.Name
'ServiceDisplayName' = $svc.DisplayName
'ShutDownStart' = $shutStart
'ShutDownEnd' = Get-Date
'Result' = $shutResult
}
}
else {
[PsCustomObject]#{
'ServiceName' = $service
'ServiceDisplayName' = ''
'ShutDownStart' = $shutStart
'ShutDownEnd' = Get-Date
'Result' = "Failed: Service '$service' could not be found."
}
}
}
# output on screen
$result
# output to CSV
$result | Export-Csv 'D:\appreport.csv' -Delimiter ";" -Force -NoTypeInformation
The output on screen will look like this:
ServiceName : SQLTELEMETRY$TESTDB
ServiceDisplayName :
ShutDownStart : 22-8-2019 16:47:40
ShutDownEnd : 22-8-2019 16:47:40
Result : Failed: Service 'SQLTELEMETRY$TESTDB' could not be found.
ServiceName : MSSQL$TESTDB
ServiceDisplayName :
ShutDownStart : 22-8-2019 16:47:40
ShutDownEnd : 22-8-2019 16:47:40
Result : Failed: Service 'MSSQL$TESTDB' could not be found.
ServiceName : SQLWRITER
ServiceDisplayName : SQL Server VSS Writer
ShutDownStart : 22-8-2019 16:47:38
ShutDownEnd : 22-8-2019 16:47:39
Result : Success
Hope that helps
I don't really know when you want to capture the time stamp for the services, but I suggest you take advantage of the below property and add it in the loop where you think its suitable.
(Get-Process -Name $proc).StartTime
Also you can use the below properties :
UserProcessorTime
TotalProcessTime
ExitTime
I hope this will help you to capture to time.

How to set timeout to a PowerShell function?

I have a script which is fetching the disk space information of many machines in a call center. However, sometimes this function takes too long. I need to create a time out for that function and have been unable to. I tried using start-job but to be honest, I don't fully understand it and so I am not getting the desired results.
try {
$timeoutSeconds = 30
$code = {
param($currentPCname, $activeDriveTypes)
// Function which takes computer name as input and outputs the ComputerName,DeviceID, Size, Freespace and DriveType (3 = local)
function get-FDS {
[cmdLetBinding()]
Param([string]$hostName)
Get-WmiObject Win32_LogicalDisk -ComputerName $hostName |
Where-object {$_.DriveType -in $activeDriveTypes} |
select-Object #{Name="ComputerName";Expression={$hostName}}, #{Name="Date";Expression={Get-Date}}, DeviceID, Size, Freespace, DriveType
}
get-FDS($currentPCname) -errorAction stop
}
$processTime = measure-command {
$j = Start-Job -ScriptBlock $code -Arg $currentPCname, $activeDriveTypes
if (Wait-Job $j -Timeout $timeoutSeconds) { $tempData = Receive-Job $j }
$jobState = $j.state
Remove-Job -force $j
}
if ($jobState -ne 'Completed') {
$pcTurnedOn = $false
$errorMessage = "ERROR talking to $currentPCname : Query timed-out"
$query = "CALL sp_fds_insert_log(" + $currentRunID + ", '" + $errorMessage + "', '" + $scriptName + "');"
$cmd = new-object mysql.data.mysqlclient.mysqlcommand($query, $conn)
$cmd.executenonquery()
}
} catch {
$pcTurnedOn = $false
$errorMessage = "ERROR talking to $currentPCname : $_"
$query = "CALL sp_fds_insert_log(" + $currentRunID + ", '" + $errorMessage + "', '" + $scriptName + "');"
$cmd = new-object mysql.data.mysqlclient.mysqlcommand($query, $conn)
$cmd.executenonquery()
}
The main point of the code above is that if the line below which is calling the $code segment
$processTime = measure-command {
$j = Start-Job -ScriptBlock $code -Arg $currentPCname, $activeDriveTypes
if (Wait-Job $j -Timeout $timeoutSeconds) { $tempData = Receive-Job $j }
$jobState = $j.state
Remove-Job -force $j
}
takes more than 30 seconds which is the $timeoutSeconds, the last IF statement would be called, if the line above does not work for some reason, the catch statement would be called and if it works in less than 30 seconds, nothing would be called.
If the job finished before the timeout is reached, Wait-Job will return the job itself - if the timeout is exceeded it won't return anything:
$timeout = 2
$job = Start-Job { Start-Sleep -Seconds 3 }
$done = $job |Wait-Job -TimeOut $timeout
if($done){
# It returned within the timeout
}
else {
# Nothing was returned, job timed out
}

sql failed jobs export to csv with powershell

I am battling with a PowerShell script that captures all SQL Failed jobs for the past day and exports it to .CSV
Please view code below.
param (
#[string]$serverInstance = '03RNB-VSQLPRD4\SQLPRD04
)
begin {
[void][reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")
}
process {
try {
Write-Verbose "List failed SQL Server jobs using SMO..."
$serverInstance = Get-Content "C:\MountSpaceCollector\SQLJobFailures\servers2.txt";
$server = new-object Microsoft.SqlServer.Management.Smo.server $serverInstance
$results = #()
$reasons = #()
$jobs = $server.jobserver.jobs | where-object {$_.isenabled}
# Process all SQL Agent Jobs looking for failed jobs based on the last run outcome
foreach ($job in $jobs) {
[int]$outcome = 0
[string]$reason = ""
# Did the job fail completely?
if ($job.LastRunOutcome -eq "Failed") {
$outcome++
$reasons += "Job failed: " + $job.name + " Result: " + $job.LastRunOutcome
# Did any of the steps fail?
foreach ($jobStep in $job.jobsteps) {
if ($jobStep.LastRunOutcome -ne "Succeeded") {
$outcome++
$reasons += "Step failed: " + $jobStep.name + " Result: " + $jobStep.LastRunOutcome
}
}
}
if ($outcome -gt 0) {
$jobFailure = New-Object -TypeName PSObject -Property #{
Name = $job.name
LastRunDate = $job.lastrundate
LastRunOutcome = $reasons
}
$results += $jobFailure
}
}
Write-Output $results | Export-CSV -Path 'C:\MountSpaceCollector\SQLJobFailures\SQLJobFailures.csv' -Delimiter '|'
}
catch [Exception] {
Write-Error $Error[0]
$err = $_.Exception
while ( $err.InnerException ) {
$err = $err.InnerException
Write-Output $err.Message
Write-Output $results
}
}
}
But It Exports all except the last field (LastRunOutcome). It only displays "System.Object[]"?
Can anyone please assist with this as I do not know what I am doing wrong?
It's because $Reasons is an object, more specifically an array. You need to format the reasons differently, as a string for instance, to be able to have it appear in the CSV normally.
Perhaps you meant to use the string $Reason that you declare, but don't use?

Powershell Timeout After two Seconds

I'm new to powershell. I read some lines on www.powershell.com. Now I need your help to solve a problem. I want to read the UUID from clients in the Network. Therefore I created a document "pcs.txt" where all PCs are stored.
$pc = Get-Content pcs.txt #Read content of file
$cred = Get-Credential “domain\user”
for ($i=0; $i -lt $pc.length; $i++) {
$Result=test-connection -ComputerName $pc[$i] -Count 1 -Quiet
If ($Result -eq 'True')
{
$uuid = (Get-WmiObject Win32_ComputerSystemProduct -ComputerName $pc[$i] -Credential $cred).UUID
$Ausgabe=$pc[$i] + ';'+$uuid
$Ausgabe
}
else
{
$Ausgabe=$pc[$i] + '; UUID nicht erhalten'
$Ausgabe
}
}
First I test if the ping works. When the ping works I try to get the uuid.
Sometimes I don't get the uuid even if the ping worked. So I would like to code a timeout, which say -> go to next pc when you don't have the uuid after 2 seconds.
Can you help me please?
Alas, there is no timeout parameter for Get-WmiObject commandlet. There is a feature request in MS Connect, but it is from 2011 and still open.
A workaround, which I haven't tested is available by using System.Management. I'll copy-and-paste it here in case the link goes dead. (And I hate SO answers that only contain links to resouces that may or may not exist...)
Function Get-WmiCustom([string]$computername,[string]$namespace,[string]$class,[int]$timeout=15){
$ConnectionOptions = new-object System.Management.ConnectionOptions
$EnumerationOptions = new-object System.Management.EnumerationOptions
$timeoutseconds = new-timespan -seconds $timeout
$EnumerationOptions.set_timeout($timeoutseconds)
$assembledpath = "\\" + $computername + "\" + $namespace
#write-host $assembledpath -foregroundcolor yellow
$Scope = new-object System.Management.ManagementScope $assembledpath, $ConnectionOptions
$Scope.Connect()
$querystring = "SELECT * FROM " + $class
#write-host $querystring
$query = new-object System.Management.ObjectQuery $querystring
$searcher = new-object System.Management.ManagementObjectSearcher
$searcher.set_options($EnumerationOptions)
$searcher.Query = $querystring
$searcher.Scope = $Scope
trap { $_ } $result = $searcher.get()
return $result
}
I found a good workaround!
http://theolddogscriptingblog.wordpress.com/2012/05/11/wmi-hangs-and-how-to-avoid-them/
Here my working code:
$pc = Get-Content pcs.txt #FILE FROM THE HARDDISK
$cred = Get-Credential “DOMAIN\USER” #
for ($i=0; $i -lt $pc.length; $i++)
{
$Result=test-connection -ComputerName $pc[$i] -Count 1 -Quiet
If ($Result -eq 'True')
{
$WMIJob = Get-WmiObject Win32_ComputerSystemProduct -ComputerName $pc[$i] -Credential $cred -AsJob
$Timeout=Wait-Job -ID $WMIJob.ID -Timeout 1 # the Job times out after 1 seconds.
$uuid = Receive-Job $WMIJob.ID
if ($uuid -ne $null)
{
$Wert =$uuid.UUID
$Ausgabe=$pc[$i] + ';'+$Wert
$Ausgabe
}
else
{
<#$b = $error | select Exception
$E = $b -split (:)
$x = $E[1]
$Error.Clear() #>
$Ausgabe=$pc[$i] + '; got no uuid'
$Ausgabe
}
}
else
{
$Ausgabe='PC not reached through ping.'
$Ausgabe
}
}
I hope I can help somebody with that
