Close button

I created a simple basic4ppc program. Where I have 4 forms.

1st form) Dash board (Menus)- Student - Teachers - etc
2nd form) Add Student
3rd form) View Student
4th form) Edit Student

I went to View Student , then I went to Add Student and Edit Student.

And I have a button to reach Dash board form.
I reached in dashboard form. and I closed the dashboard window form. But I got old Add Student - Edit Student- View Student forms (ie previously opened all forms).

So I wish , When I pass from one form to other form I need to close the previous one automatically. How can I do ?

Can you say any suggestion ?
:sign0085:

I think you want to close the App when you close the Dash board form, so you can use "AppClose" in the Close event.

What form do you show first ?
The first Form shown is the main form, closing this one closes the application.
Or you have the solution suggested by Pachuquin.

Best regards.
