To make it invisible use this code:

this.Hide();

BUT if you are hiding your main form, then you will have to use Application.Exit(); when you want to shut down the application. Otherwise it will still run and cause problems. If it's not the main form of your application (by that I mean Form1), then use this.Close(); to just simply get rid of the form.

Hope this helps
