The only way I can think of is to hide the parent form instead of closing
it. You can close the other forms but not the main form.

I am making a multi windows-form application where the parent form is the
login form.I want every current form to close when I go on to the next form
and not hide it or let it remain there.but when I close the parent form the
entire application closes.is there a way to do what I want to do? Thank  you
