saving details within application

Question

I am using a C# windows forms application. When I launch the project, a dialog box will appear with menus. In a particular menu, I choose Options and Options dialog box opens. Inside that, I need to enter a username and password and validate it against the DB. If credentials are correct, I should make a login form to display (I have login form as part of my project), upon closing the project and running it the next time. How do I go about doing this?

How and where should I store the result of the validation of username and password and make the project remember to launch the login form, when I launch the project next time???

Note that whatever method you choose, I recommend you don't store passwords in plain-text. In fact, coming up with your own mechanism for storing passwords at all (without a lot of "best practice" design input) is generally dangerous. — Merlyn Morgan-Graham, Nov 13 '11 at 02:02

You can try Project Properties > Settings option. VS will generate class for the settings and you can access them via Properties.Settings.Default.[PropertyName]

if(chkRememberMe.Checked)
{
Properties.Settings.Default.Username = txtUsername.Text;
Properties.Settings.Default.Password = txtPassword.Text;
Properties.Settings.Default.Save();
}

And while loading back

txtUsername.Text = Properties.Settings.Default.Username;
txtPassword.Text = Properties.Settings.Default.Password;

You should save the information into a file in any of the following directories:

ApplicationData
LocalApplicationData

See Environment.SpecialFolder.
