How to close an existing form after opening another form?
0
new to c# wandered how i can use a form to open a new form whilst also closing that initial form. I have a form that a user needs to fill out and click login on to move forward which at this point if the information is correct should open the next form and close the current one. All i seem to get is both forms closing. i can do it without closing the initial form but then it is obviously still open in the background. The form i'm trying to open is form encryption and the one 'im trying to close is form1 any help is much appreciated.
here's my code:
if (maskedTxtLogin != null)
FormEncryption Encryption = new FormEncryption();
Encryption.Show();
this.Close();
else
MessageBox.Show("Please input your initials");

it depend on whether your "initial" form is the application form (or the Main form). You cannot close the Main form (which is the Application form) and expect the child still running. The this could be referring to your Main form.

The initial form is the login form. The main form is the one that is opened by the initial form. Is their any way around this child form issue? maybe have it open from the beginning but invisible and then becomes visible when the other one is closed? do you think this could work? cheers for any help

According to Windows, the main form is the initial form. Whichever is the first form to open must stay alive for the whole life of the application. So yes, what you describe would work better.

You can control when your application closes by using a custom ApplicationContext. TheApplication.Run(new Form1())statement inProgram.Maincreate a defaultApplicationContextwithFormas its main form. By using a custom ApplicationContext and overriding theOnMainFormClosedmethod, you can redefineMainFormas it is just a property of the context. You start the application usingApplication.Run(new CustomApplicationContext).
