Add Timer.Start in your Forms LostFocus Event and in the Timer_Tick event calculate the time, if you find the time has exceeded 5 minutes close the form. — Searock, Feb 12 '13 at 08:14

write this.

    private void Form1_Activated(object sender, EventArgs e)
    {
        Timer.Enabled = false;
    }

    private void Form1_Deactivate(object sender, EventArgs e)
    {
        Timer.Enabled = true;
    }

Good, but what if form is active one, but I don't click it or move mouse over it? – Sergey Berezovskiy Feb 12 '13 at 08:36
thank you for your answer, but I don't mean when the form loses focus and is no longer the active form. I mean if the form stile on focus but not used by the system user – ahmed mohamady Feb 12 '13 at 08:38

Use the "Leave" event to manage your exit logic, like say trigger the timer.. The leave event gets fired on loosing focus.

@ahmedmohamady then how do you mean "not used by user"? You say, the form is active and there is no activity on the system? like no keyboard/mouse activity? – r.sumesh Feb 12 '13 at 08:46
you know the screen server method? I need some thing like this but the event will be closing the form – ahmed mohamady Feb 12 '13 at 08:47
