Write Output of a function in powershell window

Question

_{Wednesday, July 10, 2019 8:24 PM}

I have a GUI and it calls a function depending on the button pressed. I would like for the output of the function to show in the powershell command window when I run the GUI. The code below contains 5 buttons, when I run the powershell script and click on any of the 5 buttons, nothing happens and it just hangs, until i close out of it.

Write-Output $ping

[void]$Form.ShowDialog()

This is as close as you can get.  Normally we output to a textbox in the form.

This is how to post code in a forum.

Add-Type -AssemblyName System.Windows.Forms

$formTest = New-Object system.Windows.Forms.Form
$formTest.Size = '406,414'
$formTest.StartPosition = 'CenterScreen'
$formTest.text = "Post DC Patching Checker"

$buttonPing = New-Object system.Windows.Forms.Button
$formTest.Controls.Add($buttonPing)
$buttonPing.text = "Ping Servers / Workstations"
$buttonPing.Size = '340,50'
$buttonPing.location = '16, 97'
$buttonPing.Font = 'Microsoft Sans Serif,10'
$buttonPing.Add_Click({
    $this.Enabled = $false
    'google.com', 'test1', 'test2' |
    ForEach-Object{
        Try{
        Test-Connection $_ -Count 1 -ErrorAction Stop| 
            Out-String | 
            Write-Host -ForegroundColor green
        }
        Catch{
            Write-Host $_ -fore Red
        }
    }
    $this.Enabled = $true
})
$formTest.ShowDialog()

You cannot display output while a GUI is displayed.   PowerShell does not allow this.  The closest you can come is to use Write-Host which will output to a console window while the GUI is displayed.

Please edit you original post and post the code using the code posting tool provided.  When posted as you have done the code cannot be correctly copied.  It is also hard to read in many browsers.

There is also a very simple GUI method to display results:

'google.com','xxxx','www.msn.com','omega' | 
      Test-NetConnection  | Out-GridView
