Hi I am building a very basic GUI form in powershell to ask a user for a new password but I am having trouble setting the cancel button to go to the end of the script and not run anything if the cancel button or close icon in the top right is pressed or if no password in entered. Any help and if possible some pointers / explanations would be very welcome. Thanks in advance and see attached script

  $result =  $form1.ShowDialog()
will store the button text in $result. You can check against that, e.g.
  if ($result -eq 'Cancel') { exit }

Thanks I have added that to the end of the script and it exits correctly when cancelled is pressed but
1. when text is not entered and ok is pressed it displays the box again, then continues to run the script after ok is pressed again
2. Box is now displayed twice when entering data
Maybe I got its position wrong here is the end of the script

# Scriptblock to deturmine function of Ok & Cancel buttons
$okb1 = {
$form1.DialogResult = 1
$form1.Hide()
}
$cnb1 = {
$form1.DialogResult = 0
$form1.Hide()
}
$cancelled1 =  $form1.ShowDialog()
if ($cancelled1 -eq 'Cancel') { exit }
#Show Form 1
$form1.ShowDialog()
# Create variable from text input by user in $text1
$result1 = $text1.Text
$result1
Get-ChildItem -Path C:\nso

Yes, you called the form twice. Each ShowDialog will, of course, show the form.
# Scriptblock to deturmine function of Ok & Cancel buttons
$okb1 = {
$form1.DialogResult = 1
$form1.Hide()
}
$cnb1 = {
$form1.DialogResult = 0
$form1.Hide()
}
$btn =  $form1.ShowDialog()
if ($btn -eq 'Cancel') { exit }
# Create variable from text input by user in $text1
$result1 = $text1.Text
$result1
Get-ChildItem -Path C:\nso
