Question

Can we show the windows form for just some specific time span, say 1 minute, then close it automatically?

Answer 1

Add a Timer control from Toolbox.
Set some attributes.

    this.timer1.Enabled = true;
    this.timer1.Interval = 60000;
    this.timer1.Tick += new System.EventHandler(this.timer1_Tick);

and define Tick event handler

    private void timer1_Tick(object sender, EventArgs e)
    {
        Close();
    }
