Below mentioned code is giving error, and I'm not able to troubleshoot issue. Can anyone please help, we are just passing SourceFile and DestinationFile location to this function...
ProcessDocumentsData "D:\Files\Scan1.doc","D:\Files\Scan1.csv"
Clear-Host
function ProcessDocumentsData {
Param(
[string]$SourceFile,
[string]$DestinationFile
)
$DestinationFileName = $DestinationFile
$SourceFileName = $SourceFile
$tableNum = 13
$delimiter = ','
$objWord = New-Object -Com Word.Application
$objWord.Visible = $false # $false
$objDocument = $objWord.Documents.Open($SourceFileName)
$LETable = $objDocument.Tables.Item($tableNum)
$LETableCols = $LETable.Columns.Count
$LETableRows = $LETable.Rows.Count
$RawCSV = for($r=1; $r -le $LETableRows; $r++) {
$content= #()
for($c=1; $c -le $LETableCols; $c++) {
#Write-Host ("R:{0},C:{1}" -f $r,$c)
$content += ("`"{0}`"" -f $LETable.Cell($r,$c).Range.Text -replace "(`r|`n|`t)|$([char]7)?")
}
$Content -join $delimiter
}
$Csv = $RawCSV | ConvertFrom-Csv
$objDocument.Close()
$objWord.Quit()
# Stop Winword Process
$rc = [System.Runtime.Interopservices.Marshal]::ReleaseComObject($objWord)
$Csv
$Csv | Export-Csv $DestinationFileName -NoTypeInformation
}
I'm getting the following error:

In PowerShell, when calling a function multiple parameters are delimited by a whitespace.
Try to call the function like that:
ProcessDocumentsData "D:\Files\Scan1.doc" "D:\Files\Scan1.csv"

I have a PowerShell script that goes out grabs the currently logged in user on a remote computer and gets the total size of their local profile C:\users\USERNAME\documents, pictures, music, etc. I have confirmed that the remote computer is online and the user is logged in. While the script is working, in the sense that it gets the folder size, it returns this message:

I'm confused because if I'm reading the message correctly it shouldn't be able to grab the username thus not get the correct folder and the size.
Here is the code that I'm running
foreach ($system in Get-Content "C:\net_view.txt")
{
$colItems = 0
$user = Get-WmiObject Win32_ComputerSystem -ComputerName $system |
Select-Object -ExpandProperty UserName
$pos = $user.IndexOf("\")
$user = $user.Substring($pos+1)
$path = $system +"\c$\users\" + $user
$colItems = (Get-ChildItem $path -Recurse -ErrorAction SilentlyContinue |
Measure-Object -property length -sum)
"{0:N2}" -f ($colItems.sum / 1MB) + " MB"
Add-Content C:\users\administrator\desktop\profile_size.txt ($colItems.sum / 1MB)
Add-Content C:\users\administrator\desktop\profile_size.txt $system
}
$commonElementsLocation = ((Get-Location).Path + "\FolderMatchingCommonWords.txt")
if ($commonElementsLocation) {
$result += Start-Job -InitializationScript {
$commonElements = Get-Content -Path $commonElementsLocation
} -ScriptBlock $testScriptBlock -ArgumentList "testing" | Wait-Job | Receive-Job
}
Not sure what I am doing wrong here - probably a stupid mistake, but I put a condition around the Start-Job statement, and powershell still gives the following error:
Get-Content : Cannot bind argument to parameter 'Path' because it is null.

You have already used a variable for a script block once with $testScriptBlock. You could just do that again for -InitializationScript?
$anotherSB = [scriptblock]::create("$commonElements = (Get-Content -Path $commonElementsLocation)")
$result += Start-Job -InitializationScript $anotherSB -ScriptBlock $testScriptBlock -ArgumentList "testing" | Wait-Job | Receive-Job
I have a working powershell script, but when it cannot find a hostname, it throws a non-terminating exception and writes to the screen that that hostname was unable to be found. I want to catch that exception and simply write to the screen: Not Found. Then I want the script to carry on like normal.
Here is the script:
$listOfComputers = IMPORT-CSV test.txt
$b = "2013-09-11"
ForEach($computer in $listOfComputers){
$name = $computer.Name
Write-Host $name -NoNewLine
try{$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $name)}
catch [Exception] {write-host " Not Found" -foreground blue}
$key = $reg.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\WindowsUpdate\\Auto Update\\Results\\Install")
$a = $key.GetValue("LastSuccessTime")
$a = $a.Substring(0,10)
if($a -le $b){Write-Host " " $a -foreground magenta}
else{Write-Host " " $a}
}
Here is the output:
PS C:\PowerShell Scripts> .\windowsUpdates.ps1

Any help is appreciated.
Skip the try/catch altogether, and instead test for connectivity before attempting to access the registry. This should speed your script up, as you won't be waiting for a timeout from OpenRemoteBaseKey on systems that are offline.
$listOfComputers = IMPORT-CSV test.txt
$b = "2013-09-11"
ForEach($computer in $listOfComputers){
$name = $computer.Name
Write-Host $name -NoNewLine
if (-not (Test-Connection -computername $name -count 1 -Quiet -ErrorAction SilentlyContinue) {
write-host " Not Found" -foreground blue;
continue;
}
$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $name)
$key = $reg.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\WindowsUpdate\\Auto Update\\Results\\Install")
$a = $key.GetValue("LastSuccessTime")
$a = $a.Substring(0,10)
if($a -le $b) {
Write-Host " " $a -foreground magenta
}
else {
Write-Host " " $a;
}
}
You could also test connectivity in bulk before hitting the main loop, filtering any computers that aren't accessible out of your list. See my answer over here for a way to do that.
I have code that uses ProcessStartInfo and Process to invoke another script, and to return the output of that script.
Unfortunately, I am getting errors, and I am unsure how to troubleshoot them.
#script1.ps1
$abc = $args
$startInfo = $NULL
$process = $NULL
$standardOut = $NULL
<#Previously created password file in C:\Script\cred.txt, read-host -assecurestring | convertfrom-securestring | out-file C:\Script\cred.txt#>
$password = get-content C:\Script\cred.txt | convertto-securestring
$startInfo = New-Object System.Diagnostics.ProcessStartInfo
$startInfo.FileName = "powershell.exe"
$startInfo.Arguments = "C:\script\script2.ps1", $abc
$startInfo.RedirectStandardOutput = $true
$startInfo.UseShellExecute = $false
$startInfo.CreateNoWindow = $false
$startInfo.Username = "DOMAIN\Username"
$startInfo.Password = $password
$process = New-Object System.Diagnostics.Process
$process.StartInfo = $startInfo
$process.Start() | Out-Null
$standardOut = $process.StandardOutput.ReadToEnd()
$process.WaitForExit()
# $standardOut should contain the results of "C:\script\script2.ps1"
$standardOut
The errors I get are:
Exception calling "Start" with "0" argument(s): "Logon failure: unknown user name or bad password"

How can I fix this problem?
It's pretty much spelled out to you, isn't it?:
"Logon failure: unknown user name or bad password"
(first error line).
Note that DOMAIN should be provided in separate property:
$startInfo.Username = "Username"
$startInfo.Domain = "DOMAIN"
