Password Reset with GUI Improvements - powershell

Question

I am working on a Password Reset Script with a GUI and have 3 questions If any body is able to help me :) the premise is that when I user scans their card it will show their username and password, it functions as it should be I want to develop it further.
If the box is empty and ‘okay’ is selected then it uses every row in the CSV, is there a way to set it up so the OK button can't be pressed until something is entered. The RFID scanner used always hits a return.
After the pop box has been displayed I want to add a timer for 15 seconds before it closed and then when the pop-up box disappears it then asks for the next person to scan their card. As it stands at the moment, when the message box appears it closes the original form. Is there any way for me to keep the entry form open rather than it shutting, and show the message box over the top of the form? I basically want to reset the form after the user has been given their details.
When I have the form created at the top I can style it. Am I able to do the same for the message box so it can be styled? Thank you so much in advance.
Any help would be massively appreciated. I am still learning the basics of PowerShell

Hopefully, below (read the inline comments) explains your questions 1 and 2.

# remove the next line if you want the mainform to stay open

$okButton.Add_Click({

if($targetUser){

}
# reset the form by clearing out the textbox

})
$form.AcceptButton = $okButton
$form.Controls.Add($okButton)

})
$form.Controls.Add($textBox)
$form.Topmost = $true
$form.Add_Shown({$textBox.Select()})
$result = $form.ShowDialog()
# Important, remove the form from memory when done
$form.Dispose()
I'm not really sure what you mean with the third question though: "Am I able to do the same for the message box so it can be styled?"
Since you're using a System.Windows.MessageBox, there is nothing you can do about its default appearance, since A message box is a prefabricated modal dialog box that displays a text message to a user.
If you want a self-styled messagebox, you'll have to create one yourself.
