How to fire an event on form close

Question

I think I'm missing something in the syntax. I have two win forms. One is Login and the other is Main. Upon successful login, Login form gets hidden and Main is shown. When I quit the Main, Login is still active in the background so the app is still running. How to fire an Application.Exit() when Main gets closed, I've tried a bunch of functions but none seem to do the trick?

Answer 1

that mean to:

login form for button "OK" put:
me.hide()
mainform.show()

mainform for button "Close" put:
me.close()

Answer 2

did you try to put in the login form
main.show()
me.hide()

Answer 3

if you are using visual basic in the login form this code will work

me.hide()
Mainform.show()

you can use "me.close()" in the Mainform and it will close the application.

this.hide() // this is not defined in visual basic

Answer 4

No, it's called from Login form -
on button click if user / pass OK then
this.hide
MainForm.show

But I don't know what is the event that is triggered when I close the Main form, so I can put Application.Exit() inside it.
