Test connection and output in GUI screen in Powershell-CodePudding

With the below code, my goal is to ping a hostname and have it return if successful or unsuccessful, and project that on the GUI screen itself. At the moment I am getting errors on the "-TargetName".

Add-Type -assembly System.Windows.Forms

# Create window form 
$main_form = New-Object System.Windows.Forms.Form
$main_form.Text = 'Device Info'
$main_form.Width = 600
$main_form.Height = 400
$main_form.AutoSize = $true

# Start of code
$Label = New-Object System.Windows.Forms.Label
$Label.Text = "Hostname"
$Label.Location = New-Object System.Drawing.Point(10, 30)
$Label.AutoSize = $true
$main_form.Controls.Add($Label)

# Adding textbox
$TextBox = New-Object System.Windows.Forms.TextBox
$TextBox.Location = New-Object System.Drawing.Point(90, 30)
$TextBox.Width = 300
$main_form.Controls.Add($TextBox)

# Adding check button
$CheckButton = New-Object System.Windows.Forms.Button
$CheckButton.Location = New-Object System.Drawing.Size(400, 30)
$CheckButton.Size = New-Object System.Drawing.Size(120, 23)
$CheckButton.Text = "Check"
$main_form.Controls.Add($CheckButton)

# Perform event when check button is clicked
$ComputerName = $TextBox.Text 

$CheckButton.Add_Click(
    {
        Test-Connection -TargetName $ComputerName -IPv4
    }
)

# Show Window
$main_form.ShowDialog()

CodePudding user response：

You need to grab the value from $TextBox.Text when the button is clicked, and then use the correct parameter name (-ComputerName rather than -TargetName)!

Change this:

$ComputerName = $TextBox.Text 

$CheckButton.Add_Click(
    {
        Test-Connection -TargetName $ComputerName -IPv4
    }
)

To:

$CheckButton.Add_Click(
    {
        $ComputerName = $TextBox.Text 
        Test-Connection -ComputerName $ComputerName -IPv4
    }
)
