Editing Scripts with an App

PowerShell Universal

Product: PowerShell Universal
Version: 2026.1.5

Hi, I wanted to reach out to you again regarding a different issue. Is there a way in PowerShell Universal to adjust an existing target script from within an app, using predefined Forms variables (two UD-Selects and one textbox)? I would like to use this app as a basis to revise the parameters of the respective scripts. Example:

New-UDApp -Content {
    New-UDCard -Title "Test-App" -Content {
        New-UDDivider
        New-UDElement -Tag 'br'
        New-UDStack -Direction 'column' -Spacing 3 -Content {
            New-UDForm -Content {
                New-UDSelect -Id 'SelectArt' -Label 'Art Selection' -Option {
                    New-UDSelectOption -Name 'IT' -Value 'IT'
                    New-UDSelectOption -Name 'Sales' -Value 'Sales'
                    New-UDSelectOption -Name 'Manager' -Value 'Manager'
                } -DefaultValue 'Alle' -FullWidth

                New-UDSelect -Id 'SelectOU' -Label 'OU Selection' -Option {
                    $ADSystemOUs = Get-ADOrganizationalUnit -Filter * -SearchBase $Searchbase -SearchScope OneLevel  -Properties | Sort-Object Name
                    foreach ($ou in $ADSystemOUs) {
                        New-UDSelectOption -Name $ou.Name -Value $ou.DistinguishedName
                    }
                } -FullWidth -Multiple

                New-UDTextbox -Id 'TxtAdGroup' -Label 'AD-Group' -Placeholder 'AD-Group' -FullWidth
                New-UDElement -Tag 'br'
            } -OnSubmit {
                $Art = $EventData.SelectArt
                $OU = $EventData.SelectOU
                $Group = $EventData.TxtAdGruppe
            } -ButtonVariant outlined -SubmitText "Submit"
        } -FullWidth
    }
}

I would like to use the above-mentioned code, as described, to save an existing script (and others) with the data selected in the app. I know that I can use Get-PSUScript to call the respective scripts, but so far I have not found a way to pass information to them.

Can’t you invoke the script with the paramaters you’ve selected?

universal-docs/cmdlets/Invoke-PSUScript.txt at v5 · ironmansoftware/universal-docs

If you’re looking to save the script with hard parameters, you can use placeholders;

For example, if you created the script below in a file named test.ps1

# Filename test.ps1
Write-Output “Hello ~HelloWhat~”

Then did something similar to this with your app

# App Content
…
New-UDSelect -Id ‘HelloWhat’ -Label ‘HelloWhat’ -Option {
    New-UDSelectOption -Name ‘World’ -Value ‘World’
    New-UDSelectOption -Name ‘Kitty’ -Value ‘Kitty’
    New-UDSelectOption -Name ‘Sailor’ -Value ‘Saillor’
} -DefaultValue ‘Alle’ -FullWidth
…
(Get-PSUScript -Name test.ps1).Content -Replace “~HelloWhat~“, “$($EventData[0])” | Set-Content -Path NewFile.ps1

I’ve put that together off the top of my head and the syntax might not be quite right - but the method should work even though a bit of tweaking might be needed.

Hey there, the solution in my case would be set-psuscript. But, when i run the job, i ll get an error-message:

Set-PSUScript -Name $ScriptName -Content $UpdatedContent -AppToken $appToken -ComputerName $serverAddress

Status(StatusCode="Cancelled", Detail="No message returned from method.")

Thats the code I use

$ScriptContent = Get-PSUScript -Name $ScriptName -ComputerName $serverAddress -AppToken $appToken
$UpdatedContent = $ScriptContent.content.Replace('(\$Area\s*=\s*".*")','$Area = {0}' -f $newArea).Replace('(\$Target\s*=\s*".*")','$Target = {0}' -f $newTarget)
Set-PSUScript -Name $ScriptName -Content $UpdatedContent -AppToken $appToken -ComputerName $serverAddress

I have found the solution to my problem. I need to reference the Script ID in set-psuscript in order for the editing to be carried out.

Here is the final code:

# Replace Area
$UpdatedContent = $Script.Content -replace '(\$Area\s*=\s*".*")', ('$Area= {0}' -f $newArea)
# Replace Target
$UpdatedContent = $UpdatedContent -replace '(\$Target\s*=\s*".*")', ('$Target= {0}' -f $newTarget)

Set-PSUScript -id $Script.id -Content $UpdatedContent -ComputerName $serverAddress -AppToken $appToken
