Hi,

I need to implement a login form in win form application.
My scenario is :- Login form should open first--> with correct user name and password user should be able to login--> then another page should open and login page should get closed.

Problem is:- Since log in page is the first page and it need to get put in Main() function like below.

static void Main()
{
   Application.EnableVisualStyles();
   Application.SetCompatibleTextRenderingDefault(false);
   Application.Run(new login());
}

After opening another form by formname.show() If I get exit from loginpage whole application will get exit.

Please how I can open another form without application exit and login form as my first form ?

The easiest way is to make the login form the first form.
Then, when they have correctly logged in, create an instance of your new form, and hook into the FormClosed event.

frmMain fm = new FrmMain();
fm.FormClosed += new FormClosedEventHandler(frmMain_FormClosed);

Show the new form with Form.Show() and use Hide on your login form.
When the FormClosed event fires, your handler can either re-display the login form with Show() or exit the application.

If you set the login form ShowInTaskbar to false then no icon will appear either.
