C# Opening a new form and closing the other one

Question

In my program I show a login form before the main form, once the program detects a successful login I use this:

MainForm Main = new MainForm();
Main.Show();
         


        

Answer 1

Change the main form to be MainForm, and when the application launches, in your MainForm_Load launch login form as a dialogbox, so they cannot access the main form.

• If you need to be able to close the application from the login form, use Application.Exit(0);
• If you don't want them to see the main form lookup and override SetVisibilityCore and call it inside MainForm_Load.
