Close form...

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.Run Dialog 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.

My WinForms application can have any number of top level forms open at a given time. If the user selects File|Exit, all of the forms are closed.

Hi, At a certain point in my application, I have access to a Form object. I want to close that form: form.Close(); There are any number of reasons why this form might not close. A common reason might be that the user answered "No" when the form's OnClosing() override asked him "Are you sure you want to close this form?"

I guess this is a simple one but I can't seem to get it to work. I want to refresh an open form "onClose" of another. I have a Close button on a form which has User Details on it. If I update the data on that from, I want it to automatically refresh the details which are shown on an open form.

I need help with code to close two forms at the same time, FormA and FormB. I need code that can be used from either form and needs to work with both a 'Close' button on each form as well as if the user clicks the 'X' in the control box. I have a function, IsObjectOpen, that can be used to check if a form is open. The function is used as follows: X = IsObjectOpen(FormName,2)

oForm.Close() vs this.Close() in a modal dialog. oFrom.Close() calls Form.Dispose() but this.Close() ,say in the click event of the Form, does not. I can think of the reason for this but is this documented and if so can someone give me the reference. And is this true for .net 1 and 2. Thanks
