Powershell UI - DialogResult - PropertyAssignmentException - powershell

Question

I am creating a powershell UI for some Script.
Now I am running in an error. But first, here is my code of my form:
$form_appBase = New-Object System.Windows.Forms.Form
$form_appBase.Text = 'APP Policy creator'
$form_appBase.Width = 350
$form_appBase.Height = 150
$form_appBase.AutoSize = $true
$label_appFilename = New-Object System.Windows.Forms.Label
$label_appFilename.Location = '10,10'
$label_appFilename.Size = '200,15'
$label_appFilename.Text = 'Program'
$Textbox_appFilename = New-Object System.Windows.Forms.TextBox
$Textbox_appFilename.Location = '10,30'
$Textbox_appFilename.Size = '200,25'
$label_appVersion = New-Object System.Windows.Forms.Label
$label_appVersion.Location = '220,10'
$label_appVersion.Size = '100,15'
$label_appVersion.Text = 'Version:'
$Textbox_appVersion = New-Object System.Windows.Forms.TextBox
$Textbox_appVersion.Location = '220,30'
$Textbox_appVersion.Size = '100,25'
$label_appProgPath = New-Object System.Windows.Forms.Label
$label_appProgPath.Location = '10,60'
$label_appProgPath.Size = '130,15'
$label_appProgPath.Text = 'Path to PROG Policy'
$textbox_appProgPath = New-Object System.Windows.Forms.TextBox
$textbox_appProgPath.Location = '150,60'
$textbox_appProgPath.Size = '170,25'
$Radio_appBaseSW = New-Object System.Windows.Forms.RadioButton
$Radio_appBaseSW.Location = '10,90'
$Radio_appBaseSW.Size = '100,15'
$Radio_appBaseSW.Text = "Software"
$Radio_appBaseSW.DialogResult = [System.Windows.Forms.DialogResult]::SW
$Radio_appBaseHW = New-Object System.Windows.Forms.RadioButton
$Radio_appBaseHW.Location = '10,110'
$Radio_appBaseHW.Size = '100,15'
$Radio_appBaseHW.Text = "Hardware"
$Radio_appBaseHW.DialogResult = [System.Windows.Forms.DialogResult]::HW
$Button_appConfirm = New-Object System.Windows.Forms.Button
$Button_appConfirm.Location = '220,95'
$Button_appConfirm.Size = '100,30'
$Button_appConfirm.Text = "Create"
$form_appBase.Controls.Add($label_appFilename)
$form_appBase.Controls.Add($Textbox_appFilename)
$form_appBase.Controls.Add($label_appVersion)
$form_appBase.Controls.Add($Textbox_appVersion)
$form_appBase.Controls.Add($label_appProgPath)
$form_appBase.Controls.Add($textbox_appProgPath)
$form_appBase.Controls.Add($Radio_appBaseSW)
$form_appBase.Controls.Add($Radio_appBaseHW)
$form_appBase.Controls.Add($Button_appConfirm)
$form_appBase.AcceptButton = $Button_appConfirm
$dialogResultSHW = $form_appBase.ShowDialog()
}
$Button_appConfirm.Add_click(
{
if ($dialogResultSHW -eq "SW"){$appSHW = "SW"}
elseif ($dialogResultSHW -eq "HW"){
$appSHW = "HW"
$appFilename = $Textbox_appFilename.Text
$appVersion = $Textbox_appVersion.Text
$appProgPath = $textbox_appProgPath.Text
$appUNCPath = "\\zen\netlogon\applocker\Output + '\' + $appSHW + '-' + $appFilename + '-' $appVersion + '.' + 'xml' "
Write-Host "$appFilename"
Write-Host "$appVersion"
Write-Host "$appProgPath"
Write-Host "$appSHW"
Write-Host "$appUNCPath"
powershell.exe -file \\zen\netlogon\applocker\applockerwork.ps1 -application -in $appProgPath -out $appUNCPath
}
}
)
After checking everything, I get the following error:
Powershell_Error
Can anyone help me to find out why this error persists? I tried many Ideas I found on the WWW but nothing seemed to work.

First of all, the [System.Windows.Forms.DialogResult] enum does not have values like "SW" or "HW"..
Remove the lines $Radio_appBaseSW.DialogResult = ... and $Radio_appBaseHW.DialogResult = ... because as guiwhatsthat commented, the RadioButtonClass does not have such a property.
Also change $dialogResultSHW = $form_appBase.ShowDialog() into [void]$form_appBase.ShowDialog()
Then, in your $Button_appConfirm.Add_click({..}) event, do
$appSHW = if ($Radio_appBaseSW.Checked) { "SW" } elseif ($Radio_appBaseHW.Checked) {"HW"}
and use the value of $appSHW do perform the different actions, or simply do
if ($Radio_appBaseSW.Checked) {
# perform action for choice Software
}
elseif ($Radio_appBaseHW.Checked) {
perform a different action for choice Software
}
else {
# no radiobutton was touched... Alert the user to select either the Software or the Hardware radio button
}
Finally, do not forget to remove the form from memory when you are done with it with $form_appBase.Dispose()
