I developed a Windows mobile application using C#. I want when I install my application on mobile to prevent this mobile from going to sleep mode, I found that SystemIdleTimerReset() function does that. BUT I don't know where to put and how to let it be called every 30 seconds ???

and the most important thing... will it work if I press sleep mode button?

Sorry for the delay, I only got notified when you changed my answer:

Not that familiar with CE3, but it should just be a case of:

    Timer tim = new Timer();
    tim.Interval = 30000;
    tim.Tick += new EventHandler(tim_Tick);
    }
void tim_Tick(object sender, EventArgs e)
    {
    SystemIdleTimerReset();
    }

As for your sleep button, On sleep disable the timer, on wakeup restart it.

SystemIdleTimerReset is there to prevent the mobile device from going into sleep mode to preserve the battery power. If you continually call it, the battery is going to go flat quite quickly. If you must do this, set up a Timer with a thirty second interval, and call SystemIdleTimerReset from that. As a user though, I would get extremely fed up if an app ignored my power-down settings and flattened my battery!
