PowerShell Function form

Hello Techies,

I have created a form using PowerShell script which contain credentials on top and at the bottom contains other components. now the credentials and other functions in the form is working as expected. now the issue is when i enter the credentials and hit enter, the window (form) get closed, however login is successful, now my query is, i don't want the form to get closed once credentials are entered and login is successful. can we achieve it by either popping up another window or display a message at bottom that login is successful and can continue based on login authentication to the bottom contents.

Please suggest.

regards
Vinay
