I have slightly modified this PowerShell script for my work with DOCX files but would like to edit the DOCX file in place.
After running the script, the terminal displays the error message: "You cannot call a method on a null-value expression" in reference to line 43, $document.Save().
I am not sure the reason for the error as the path to $document is already defined earlier in the script. What am I missing?
Here is the whole script:
Param ([string]$path = $(throw "-path is required."))

$runs = Invoke-GenericMethod -InputObject $MainDocumentPart.Document -MethodName Descendants -GenericType DocumentFormat.OpenXml.Wordprocessing.Run
foreach ($run in $runs) {
if ($run.RunProperties.Languages.Val) {
<#[String]$value = $run.InnerText#>
[String]$language = $run.RunProperties.Languages.Val
'{{$span xml:lang="{0}"$}}{1}{{$/span}}$' -f $language, $run.InnerText
}
}
$document.close()
Update:
After modifying the script, I now no longer have the problem with "You cannot call a method on a null value expression" error. The problem is that I am not sure how to save results to the file.
This may be a duplicate of this thread.
Can anyone suggest a method for saving the changes to the file?
Variable names in PowerShell are NOT case-sensitive. You destroy your "document" with this line I think:
[DocumentFormat.OpenXml.Wordprocessing.Document]$Document = $document.Document
Because $Document is the same variable as $document.

function-name | ConvertTo-CSV -NoTypeInformation | Add-Content -Path $($af_fp)
Above is the generalized (and abbreviated) script contents for a powershell script.
Every time I run the script in this way, I get the following error:
Add-Content : Could not find a part of the path 'C:\Users\timeuser\Documents\'.
At C:\Users\timeuser\Documents\get_software.ps1:231 char:51

+ FullyQualifiedErrorId : GetContentWriterDirectoryNotFoundError,Microsoft.PowerShell.Commands.AddContentCommand
When I run
Get-Variable -Scope global
after running the script and seeing the error, the variable af_fp contains exactly the information I am seeking for the file name, however, the error shows the variable contents ending in ':String'.
To confuse me even more, if I comment out the lines containing '$global:...' and re-run the same script, IT ACTUALL RUNS AND SAVES THE FILE USING THE LINE
function-name | ConvertTo-CSV -NoTypeInformation | Add-Content -Path $($af_fp)
AS INTENDED. Of course, I had to run the script and watch it error first, then re-run the script with the global variable declaration and update commented out for it to actually work. I want to run the script ONCE and still get the same results.
FYI, I am a complete noob to powershell, but very familiar with the concept of variable scope.....but why is this global not working when initially created and updated, but then work the second time around, when, as far as I can tell, the CONTENT AND SCOPE of the global remains the same...…. any assistance to finding a solution to this small issue would be greatly appreciated; I have tried sooooo may different methods from inquiries through here and on Google...…..
EDIT: not sure why this will matter, because the script ran before as intended when I explicitly typed the parameter for -Path as 'C:\path\to\file'. The ONLY CHANGES MADE to the original, working script (below) were my inclusion of the global variable declaration, the update to the contents of the global variable (near the end of the function), and the attempt to use the global variable as the parameter to -Path, that is why I omitted the script:

IGNORE FORMATTING PLEASE- HAD TROUBLE MAKING INDENTS CORRECTLY FROM COPY-PASTE AND RESTRICTIONS ON SITE FOR CODE BLOCKS.....
NOTE: the ONLY changes I made, that I am asking about, are the global declaration, the global variable update in the function, and the attempt to use the global variable for the -Path parameter....script otherwise runs and will even run WITH THE LAST LINE AS IS if I ran it and errored the first time.....not sure how the addition script will help in any way, shape, or form!
With a little effort, Nasir's solution worked! HOWEVER, I ran across a sample file that had a way of adding to a parameter that inspired me to make a change to my ORIGINAL, that also worked: remove global variable from script entirely and add this code the very end:
$file_suffix = '_AF.csv'
Get-Software | ConvertTo-CSV -NoTypeInformation | Add-Content -Path $env:COMPUTERNAME$file_suffix
In this way, I was able to accomplish exactly what I was setting out to do! Thanks Nasir for your response as well! I was able to also make that work as intended!
Global variables are generally frowned upon, since they often lead to poor scripts, with hard to debug issues.
It seems like your function returns some stuff, which you need to write to a file, the name of which is also generated by the same function. You can try something like this:
function function-name {
param($PathPrefix)
#do things
[pscustomobject]#{"DoThings_data" = $somevariablefromDoThings; "Filename" = "$($PathPrefix)$($variableFromDo_Things)_AF.csv"}
}
function-name -PathPrefix "C:\Path\to\folder\" | Foreach-Object { $_.DoThings_data | Export-Csv -Path $_.Filename -NoTypeInformation }
Or just have your function write the CSV data out and then return the data if you need to further process it outside the function.
Edit: this is just me extrapolating from partial code you have provided. To Lee_Dailey's point, yes, please provide more details.
I'm trying to create a Powershell script that will setup a brand new workspace in a temporary location, do a GetLatest on selected solutions/projects, and download the source code so that I can then trigger further build/versioning operations.
I think I have the script more or less right, but the problem is every time I run this, it tells me there were 0 operations... i.e. I already have the latest versions. This results in nothing at all being downloaded.
Can anyone see what I'm doing wrong?

The "$/Client1/Project1" string smells. I would add a backtick before the dollar sign so it is not read as a variable or use single quotes.
Backtick
"`$/Client1/Project1"
Single quote
'$/Client1/Project1'
I have a text file that contains some text and end of the file
"Version"="1.3.0"
I would like to increment the build number "Version"="1.4.0".
in the same file, without affecting the other contents.
help needed in powershell please.
I assume you can parse the file to the point you get to similar content you give in your question. Additionally, my example is lacking in error handling.
Example
$fileContents = '"Version"="1.4.0"'
$parts=$fileContents.Split('=')
$versionString = $parts[1].Replace('"','')
$version = [Version]$versionString
$newVersionString = (New-Object -TypeName 'System.Version' -ArgumentList #($version.Major, ($version.Minor+1), $version.Build)).ToString()
$fileContents.Replace($versionString,$newVersionString)
Result
"Version"="1.5.0"
Thanks a lot #Matt && #TravisEz13 for your tips. with your help here is the another working version.
$Verfile = "C:\Work\Example\versionfile.reg"
$fileContents = (Get-Content $Verfile | Select -Last 1)

$version = [Version]$versionString
$newVersionString = (New-Object -TypeName 'System.Version' -ArgumentList #($version.Major, ($version.Minor+1), $version.Build)).ToString()
(gc $Verfile) -replace "$versionString", "$newVersionString" | sc $Verfile
I'm new at writing in powershell but this is what I'm trying to accomplish.
I want to compare the dates of the two excel files to determine if one is newer than the other.
I want to convert a file from csv to xls on a computer that doesn't have excel. Only if the statement above is true, the initial xls file was copied already.
I want to copy the newly converted xls file to another location
If the file is already open it will fail to copy so I want to send out an email alert on success or failure of this operation.
Here is the script that I'm having issues with. The error is "Expressions are only allowed as the first element of a pipeline." I know it's to do with the email operation but I'm at a loss as to how to write this out manually with all those variables included. There are probably more errors but I'm not seeing them now. Thanks for any help, I appreciate it!

You get this error when you are trying to execute an independent block of code from within a pipeline chain.
Just as a different example, imagine this code using jQuery:
$("div").not(".main").console.log(this)
Each dot (.) will chain the array into the next function. In the above function this breaks with console because it's not meant to have any values piped in. If we want to break from our chaining to execute some code (perhaps on objects in the chain - we can do so with each like this:
$("div").not(".main").each(function() {console.log(this)})
The solution is powershell is identical. If you want to run a script against each item in your chain individually, you can use ForEach-Object or it's alias (%).
Imagine you have the following function in Powershell:
$settings | ?{$_.Key -eq 'Environment' } | $_.Value = "Prod"
The last line cannot be executed because it is a script, but we can fix that with ForEach like this:
$settings | ?{$_.Key -eq 'Environment' } | %{ $_.Value = "Prod" }
This error basically happens when you use an expression on the receiving side of the pipeline when it cannot receive the objects from the pipeline.
You would get the error if you do something like this:
$a="test" | $a
or even this:
"test" | $a
I don't know why are trying to pipe everywhere. I would recommend you to learn basics about Powershell pipelining. You are approaching it wrong. Also, I think you can refer to the link below to see how to send mail, should be straight forward without the complications that you have added with the pipes : http://www.searchmarked.com/windows/how-to-send-an-email-using-a-windows-powershell-script.php
Using in PowerShell, how can I check if an application is locking a file?
I like to check which process/application is using the file, so that I can close it.
You can do this with the SysInternals tool handle.exe. Try something like this:
PS> $handleOut = handle
PS> foreach ($line in $handleOut) {
if ($line -match '\S+\spid:') {
$exe = $line
}
elseif ($line -match 'C:\\Windows\\Fonts\\segoeui\.ttf') {
"$exe - $line"
}
}
MSASCui.exe pid: 5608 ACME\hillr - 568: File (---) C:\Windows\Fonts\segoeui.ttf
...
This could help you: Use PowerShell to find out which process locks a file. It parses the System.Diagnostics.ProcessModuleCollection Modules property of each process and it looks for the file path of the locked file:
$lockedFile="C:\Windows\System32\wshtcpip.dll"
Get-Process | foreach{$processVar = $_;$_.Modules | foreach{if($_.FileName -eq $lockedFile){$processVar.Name + " PID:" + $processVar.id}}}
You should be able to use the openfiles command from either the regular command line or from PowerShell.
The openfiles built-in tool can be used for file shares or for local files. For local files, you must turn on the tool and restart the machine (again, just for first time use). I believe the command to turn this feature on is:
openfiles /local on
For example (works on Windows Vista x64):
openfiles /query | find "chrome.exe"
That successfully returns file handles associated with Chrome. You can also pass in a file name to see the process currently accessing that file.
You can find a solution using Sysinternal's Handle utility.
I had to modify the code (slightly) to work with PowerShell 2.0:
#/* http://jdhitsolutions.com/blog/powershell/3744/friday-fun-find-file-locking-process-with-powershell/ */
Function Get-LockingProcess {
[cmdletbinding()]

# Define the path to Handle.exe
# //$Handle = "G:\Sysinternals\handle.exe"
$Handle = "C:\tmp\handle.exe"
# //[regex]$matchPattern = "(?<Name>\w+\.\w+)\s+pid:\s+(?<PID>\b(\d+)\b)\s+type:\s+(?<Type>\w+)\s+\w+:\s+(?<Path>.*)"
# //[regex]$matchPattern = "(?<Name>\w+\.\w+)\s+pid:\s+(?<PID>\d+)\s+type:\s+(?<Type>\w+)\s+\w+:\s+(?<Path>.*)"
# (?m) for multiline matching.
# It must be . (not \.) for user group.
[regex]$matchPattern = "(?m)^(?<Name>\w+\.\w+)\s+pid:\s+(?<PID>\d+)\s+type:\s+(?<Type>\w+)\s+(?<User>.+)\s+\w+:\s+(?<Path>.*)$"
# skip processing banner
$data = &$handle -u $path -nobanner
# join output for multi-line matching
$data = $data -join "`n"
$MyMatches = $matchPattern.Matches( $data )
# //if ($MyMatches.value) {
if ($MyMatches.count) {
$MyMatches | foreach {
[pscustomobject]#{
FullName = $_.groups["Name"].value
Name = $_.groups["Name"].value.split(".")[0]
ID = $_.groups["PID"].value
Type = $_.groups["Type"].value
User = $_.groups["User"].value.trim()
Path = $_.groups["Path"].value
toString = "pid: $($_.groups["PID"].value), user: $($_.groups["User"].value), image: $($_.groups["Name"].value)"
} #hashtable
} #foreach
} #if data
else {
Write-Warning "No matching handles found"
}
} #end function
Example:
PS C:\tmp> . .\Get-LockingProcess.ps1
PS C:\tmp> Get-LockingProcess C:\tmp\foo.txt

toString pid: 2140, user: J17\Administrator, image: WINWORD.EXE

Type File

PS C:\tmp>
I was looking for a solution to this as well and hit some hiccups.
Didn't want to use an external app
Open Files requires the local ON attribute which meant systems had to be configured to use it before execution.
After extensive searching I found.

This seems to be pure powershell and .net / C#
You can find for your path on handle.exe.
I've used PowerShell but you can do with another command line tool.
With administrative privileges:
handle.exe -a | Select-String "<INSERT_PATH_PART>" -context 0,100
Down the lines and search for "Thread: ...", you should see there the name of the process using your path.
Posted a PowerShell module in PsGallery to discover & kill processes that have open handles to a file or folder.
It exposes functions to: 1) find the locking process, and 2) kill the locking process.
The module automatically downloads handle.exe on first usage.
Find-LockingProcess()
Retrieves process information that has a file handle open to the specified path.
Example: Find-LockingProcess -Path $Env:LOCALAPPDATA
Example: Find-LockingProcess -Path $Env:LOCALAPPDATA | Get-Process
Stop-LockingProcess()
Kills all processes that have a file handle open to the specified path.
Example: Stop-LockingProcess -Path $Home\Documents
PsGallery Link: https://www.powershellgallery.com/packages/LockingProcessKiller
To install run:
Install-Module -Name LockingProcessKiller
I like what the command prompt (CMD) has, and it can be used in PowerShell as well:
tasklist /m <dllName>
Just note that you can't enter the full path of the DLL file. Just the name is good enough.
I've seen a nice solution at Locked file detection that uses only PowerShell and .NET framework classes:
function TestFileLock {
## Attempts to open a file and trap the resulting error if the file is already open/locked
param ([string]$filePath )
$filelocked = $false
$fileInfo = New-Object System.IO.FileInfo $filePath
trap {
Set-Variable -name filelocked -value $true -scope 1
continue
}
$fileStream = $fileInfo.Open( [System.IO.FileMode]::OpenOrCreate,[System.IO.FileAccess]::ReadWrite, [System.IO.FileShare]::None )
if ($fileStream) {
$fileStream.Close()
}
$obj = New-Object Object
$obj | Add-Member Noteproperty FilePath -value $filePath
$obj | Add-Member Noteproperty IsLocked -value $filelocked
$obj
}
If you modify the above function slightly like below it will return True or False
(you will need to execute with full admin rights)
e.g. Usage:
PS> TestFileLock "c:\pagefile.sys"
function TestFileLock {
## Attempts to open a file and trap the resulting error if the file is already open/locked
param ([string]$filePath )
$filelocked = $false
$fileInfo = New-Object System.IO.FileInfo $filePath
trap {
Set-Variable -name Filelocked -value $true -scope 1
continue
}
$fileStream = $fileInfo.Open( [System.IO.FileMode]::OpenOrCreate, [System.IO.FileAccess]::ReadWrite, [System.IO.FileShare]::None )
if ($fileStream) {
$fileStream.Close()
}
$filelocked
}
