Close form...

[Fabio Negri Cicotti]

Hi.

Imagine a scene where the user input the username and password in a "Login"
form and when press the confirm button, another window is opened with the
"Main" form. After that, the "Login" form is "closed" automatically.

How can I do to close the "Login" form? If I use Login.Close() on the
button_click event, both forms are closed.


Thanks a lot.

Fabio,

I would just run two message loops. The code that VS.NET produces for
you looks like this:

// Run the message loop with a form.
Application.Run(new Form1());

There is nothing that stops you from doing this:

// The login form.
LoginForm pobjLoginForm = new LoginForm();

// Show the login form.
Application.Run(pobjLoginForm);

// Apply some logic here, based on the properties of the form, like if the
user succeeded in logging in or not.

// Run the main form here.
Application.Run(new MainForm());

Hope this helps.

Thanks for your reply Nicholas.

I have tried to do what you said, but I didn't get successful. I'm taking
the follow error message:

"Additional information: It is invalid to start a second message loop on a
single thread. Use Application.RunDialog or Form.ShowDialog instead."


Any help is appreciated,

Hi, Fabio

that's exactly what you need - ShowDialog for login form.
What stops you to use it before doing Application.Run for main form?

Fabio,

Interesting, what version of the framework are you running on? I am on
1.1, and it doesn't prevent me from doing this.
