Designing a welcome screen in C#.net

Controls needed 

1. Progress bar

2. Timer control

Set the Maximum property of Progress bar to 110

and on timer1_Tick. Use the following code

private void timer1_Tick(object sender, EventArgs e)

        {

            progressBar1.Value = progressBar1.Value + 10;

            if (progressBar1.Value == 110)

            {

                timer1.Enabled = false;

                Login frm2 = new Login();

                frm2.FormClosed += new FormClosedEventHandler(frm2_FormClosed);

                frm2.Show();

                this.Hide();

            }

        } 

To close the parient form from child form use FormClosedEventHandler

 private void frm2_FormClosed(object sender, FormClosedEventArgs e)

        {

            this.Close();

        }
