I tried to use the code of this post.
When I use this code directly on PowerShell terminal it run correctly.
Add-Type -AssemblyName presentationCore
$filepath = "C:\Temp\test\Wildlife.wmv"
$wmplayer = New-Object System.Windows.Media.MediaPlayer
$wmplayer.Open($filepath)
Start-Sleep 2
$duration = $wmplayer.NaturalDuration.TimeSpan.Seconds
$wmplayer.Close()
start playing
$proc = Start-process -FilePath wmplayer.exe -ArgumentList $filepath -PassThru
But when I run the code on .bat file, a cmd window appears and disappears in a few seconds and without further action.
If I run the .bat file on CMD, this errors appear:
enter image description here
The code inserted in .bat file is:
Add-Type -AssemblyName presentationCore
$filepath = [uri] "C:\Users\??????\Desktop\small.mp4"
$wmplayer = New-Object System.Windows.Media.MediaPlayer
$wmplayer.Open($filepath)
Start-Sleep 2 # This allows the $wmplayer time to load the audio file
$duration = $wmplayer.NaturalDuration.TimeSpan.TotalSeconds
$wmplayer.Play()
Start-Sleep $duration
$wmplayer.Stop()
$wmplayer.Close()
I would be most thankful if you could help me solving this problem.
Thanks.
You are attempting to run PowerShell commands within a .bat file (as a result the PowerShell engine isn't being used to execute the code so the commands fail).
You need to save the script as a .ps1 file, then execute it from the command-line either via it's full path name or by changing to the directory where the script exists and entering:
.\scriptname.ps1
Where scriptname is the name you saved the file at.
If you want to execute the script via a .bat file, you still need to save it as a .ps1 and then create a .bat file with the following content:
Powershell.exe -File C:\path\to\my\script\myscript.ps1
Obviously correcting the path accordingly. Note there is no advantage to running the script this way, but one reason you might use a .bat file is if you needed to change the execution policy to allow script execution (I don't think you do in your case) as follows:
Powershell.exe -executionpolicy unrestricted -File C:\path\to\my\script\myscript.ps1

I'm trying to automate the execution of a simple PS script (to delete a certain .txt file). Obviously, I'm new to powershell :)
When I run the code in shell, it works flawless. But when i save the code as a .ps1 and double-click it (or execute it remotely), it just pops up a window and does nothing.
I've tried to save the code as a .bat file and execute it on Windows command line, but it behaves the same: Works by coding directly on prompt, but doesn't Works by executing the .bat file.
$Excel = New-Object -ComObject Excel.Application
$Workbook = $Excel.Workbooks.Open('H:\codes\test1.xlsm')
$workSheet = $Workbook.Sheets.Item(2)
$str_name = $WorkSheet.Cells.Item(2,1).Text
Remove-Item -Path "H:\text files\$str_name.txt" -Force
I expected it to work by double-clicking it, just as it does by running in shell, or in the command line, but i can't figure out why it doesn't.
Create a batch file which points at your .ps1 file. You may be required to run the batch file with elevated permissions, depending on your access levels (the logged in account will be used for execution).
E.g.:
Powershell.exe -executionpolicy remotesigned -File "C:\Path\script.ps1"
If this still isn't working, please execute your batch file via CMD (copying the path, wrapped in quotation marks, into CMD) and let me know the response.
There are several ways to run a .ps1 file. The simplest way is to right-click the file and choose 'Run with PowerShell'.
As others have suggested, you can also run your .ps1 file using powershell.exe either in command prompt or from a BATCH or CMD file. As follows:
powershell.exe -File C:\Script.ps1
If you are still having problems it could be the execution policy. For this, simply add -ExecutionPolicy Bypass to your command as follows:
powershell.exe -File C:\Script.ps1 -ExecutionPolicy Bypass
To change your execution policy you can use:
Set-ExecutionPolicy
I have a powershell script, p.ps1, which runs a batch-file, b.bat. The batch file runs an application MyApp.exe. I also have a log file saved in local variable $LogFile.
Is there a way to configure the PowerShell script in a way that all nested applications including MyApp.exe will write to the same log file, without changing b.bat and MyApp.exe?
I've already tried:
Start-Process "cmd.exe" "/c b.bat" -Wait | Add-Content $LogFile
And
Start-Process "cmd.exe" "/c b.bat" -Wait | Out-File $LogFile -Append
Expected Results:
All outputs will be written to $LogFile, I don't care whether outputs will be written to another log file, configured by the code of MyApp.exe.
Actual Results:
All outputs of b.bat were written to $LogFile, but the outputs from MyApp.exe were written to another log file, configured by the code of MyApp.exe.
I think I found the solution:
From the powershell file:
$command = "& 'b.bat' 'arg1' 'arg2'"
Invoke-Expression $command | Add-Content $LogFile
From the myApp code, writing in C#:
Trace.WriteLine(msg);
This way, the c# program wrote everything to the screen. The powershell script caught the output and added it to the log file using Add-Content command.
I am not a programmer and my parents' Windows 10 PC tends to loose its start menu and cortana processes, resulting in start menu not showing up at all when the start icon is clicked.
I made a quick search and found + tested this Powershell command and it worked:
Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -verbose }
I wish to turn this command into a shortcut/batchfile that executes the command and restarts the PC whenever the desktop icon is double clicked, in order to avoid explaining to my parents what to do to fix the problem. Can any one help me out please?
Thank you in Advance.
you can encode the command and put the whole thing into a single batch file (no .ps1 necessary)
details here
https://blogs.msdn.microsoft.com/timid/2014/03/26/powershell-encodedcommand-and-round-trips/
or you can use this function
https://github.com/gangstanthony/PowerShell/blob/master/Encode-Text.ps1
first, either use Get-Content or Get-Clipboard (copy your whole script to the clipboard) to encode your desired script
PS> Encode-Text (Get-Clipboard | out-string)

then you can use that in your batch file like so
powershell -encodedcommand RwBlAHQALQBBAHAAcAB4AFAAYQBjAGsAYQBnAGUAIAB8ACAAJQAgAHsAIABBAGQAZAAtAEEAcABwAHgAUABhAGMAawBhAGcAZQAgAC0ARABpAHMAYQBiAGwAZQBEAGUAdgBlAGwAbwBwAG0AZQBuAHQATQBvAGQAZQAgAC0AUgBlAGcAaQBzAHQAZQByACAAIgAkACgAJABfAC4ASQBuAHMAdABhAGwAbABMAG8AYwBhAHQAaQBvAG4AKQBcAEEAcABwAHgATQBhAG4AaQBmAGUAcwB0AC4AeABtAGwAIgAgAC0AdgBlAHIAYgBvAHMAZQAgAH0ADQAKAA==
You could execute the PowerShell script via a batch file.
Batch file:
set powerscriptPath=C:\Example.ps1
PowerShell.exe -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""%powerscriptPath%""' -Verb RunAs}"
This will bypass the execution policies on the computer allowing the script to run in Administrator mode too. NOTE: You will need to edit the powerscriptPath to point to your PowerShell script location, I just used C:\Example.ps1 as an example.
You will want to add Restart-Computer -Force to the end of your PowerShell script to restart the computer
Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -verbose }
Restart-Computer -Force
Make a bat file which executes powershell with that file. Then add a shortcut to the bat file
I am really unsure why you would run a batch file just to call a powershell script! Talk about hokey approaches to a non-problem.
To call a powershell script is really no different than calling a batch script:
It's simply path to PowerShell, and the script path as a parameter:
"%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe" "C:\users\austinfrench\desktop\example.ps1"
You can also use the exact same format as the target for a desktop shortcut.
I created a small aws.bat script and then in PowerShell I navigated to the script directory.
But when I type aws then I get an error message and it does not execute the script. Is there a special thing I should be doing?
Here's what I have tried:
PS C:\G> .\aws.bat
C:\G>$BucketName = "ab-user"
'$BucketName' is not recognized as an internal or external command,
operable program or batch file.
The very first and every othre command has a similar message.
You can't just enter the name on its own, with or without file extension, you first have to tell powershell what to do with it.
You can call it as follows:
& .\aws.bat
If you need the LastExitCode returned in powershell to check if the bat file worked (0 usually means it worked, anything else usually means it didn't), use Start-Process as follows:
$batch = Start-Process -FilePath .\aws.bat -Wait -passthru;$batch.ExitCode
And if you want the batch file to be hidden when it is run by powershell do this:
$batch = Start-Process -FilePath .\aws.bat -Wait -passthru -WindowStyle Hidden;$batch.ExitCode
I am fairly new to powershell and I am trying to create a script that executes a .exe file. I can execute them on my machine no problem because the folder path is hard coded. The problem is that if I shift this script to another computer, the .exe it calls might be located in a different folder structure. Example
My computer:
D:\Folder1\subfolder\RunMe.exe
Client computer might be
D:\RunMe\subfolder\RunMe.exe
I just need it to execute the RunMe.exe no matter where it is. Is there a way to do this in powershell?
# 1. Get the location of RunMe.exe
$RunMe = Get-ChildItem -Path d:\* -Include RunMe.exe -Recurse;
# 2. Invoke RunMe.exe
Start-Process -FilePath $RunMe[0].FullName -Wait -NoNewWindow;
