Why does a form displayed by PowerShell sometimes not show up?

Question

When I create a form (window) in PowerShell, I can usually display the form using .ShowDialog():

$form = New-Object System.Windows.Forms.Form
$form.ShowDialo         


        

Answer 1

My problem: When using ShowDialog() as part of a powershell logon script, the first form window would not show and powershell would seem to freeze up on logon. Symptoms were simular to the original post.

Solution I found: Instead of using $form.showDialog(), use:

[System.Windows.Forms.Application]::Run($form)

Works great for me now, and only the first form in the series needed the change. All my other forms that come up afterwards in the script still use showDialog.
