Add a param block to the top of your function, declaring the two paths:

function chpecent {
param(
  [string]$Path1,
  [string]$Path2
)
...
}

and then replace all hardcoded paths with those:

    $form1_Load = {
        $inputpecentw1.Text = [xml](Get-Content $Path1) | ForEach-Object { $_.SelectNodes(' //FieldCostOptions/IncreaseCost') | ForEach-Object { $_.GetAttribute("Percent") } } | Out-String
        $inputpecentw2.Text = [xml](Get-Content $Path2) | ForEach-Object { $_.SelectNodes(' //FieldCostOptions/IncreaseCost') | ForEach-Object { $_.GetAttribute("Percent") } } | Out-String
    }

... and so on, and then finally call the function like:

PS C:\> chpercent -Path1 c:\program\MIK_Autokontinent.xml -Path2 c:\program\MIK_AutoPremium.xml

@danrather you need to dot-source (or "import") the function first. . .\path\to\script.ps1; chpercent -Path1 c:\program\MIK_Autokontinent.xml -Path2 c:\program\MIK_AutoPremium.xml

Mathias R. Jessen Over a year ago

Please read the actual error messages. Add-Type -AssemblyName System.Windows.Forms

Mathias R. Jessen Over a year ago

@danrather no, at the very top of your script

Mathias R. Jessen Over a year ago

@danrather read your error messages :) Try this
