HI GUYS, FIRST OF ALL THANKS FOR THE REPLY..... ISN'T IT POSSIBLE TO CALL SOME WINDOWS API THAT CAN DO THIS JOB FOR ME? BUT I DONT HAVE ANY IDEA OF WHICH API OR HOW? OR JUST PUT IT THE OTHER WAY... HOW DOES Windows SCREENLOCK WORK? ANY IDEA?

Hi! The corresponding Win32 function is called LockWorkStation and located in user32.dll. You can simply use this code:

using System.Runtime.InteropServices;
public class ScreenLock
{
[DllImport("user32.dll")]
public static extern bool LockWorkStation();
}

thanks mav. But how do I know the system idle time? Does the API does it by itself(I hope no).....? If I use Application.Idle definitely its not gonna to work. Is there anything like System.Idle :D ? thanks once again for the help & still look forward to you suggestions...
