Specific Action For Clicking Of Close Button?

I have been developing my application for a while and need some advice on the closing. I want a code to be run when the close button is clicked but ONLY when it is clicked.

I have dried the form.disposed but that fires whenever the form is closed from the code. I just want it to do it when the close button is clicked.If you don't understand it I will give an example. I have a registation form that is the first thing a user who has not used the app before can see. When they click the close button I want the application to exit through Application.Exit(), however when they have registered the form is closed from the code through

formlogin.show()Me.close()However the Me.closE() triggers the form.disposed event and thus the application exits completely which I don't want. I know I can use the form.hide() but that keeps it running which makes the app more resource intensive.
