Can I call a sub when a user clicks on the little red x in the top right corner?

Hi there everyone. I have this student point prog, and I would like to be able to call a sub
SaveStudentBANKACC

when the user clicks on the little red x in the top right corner.

I know there is a form load event where I can call subs, but can I call it when the red x is clicked?

Thank you so much!!! :D
