How to set a timer in Windows application when user is idle

Question

I have a question in Windows Forms on setting timer when the user is idle or Inactive. I need the timer to set even on any Mouse Events. If the user makes any moment then I need to reset the timer. So this is the requirement. Here goes the code.

using System;
using System.Windows.Forms;
using Timer = System.Windows.Forms.Timer;
namespace FormsTimerSetup.Globals
{
public class SetApplicationTimeOut : Form
{
#region
///
/// Private Timer Property
///
private static Timer _timer;
///
/// Timer Property
///
public static Timer Timer
{
get
{
return _timer;
}
set
{
if (_timer != null)
{
_timer.Tick -= Timer_Tick;
}
_timer = value;
if (_timer != null)
{
_timer.Tick += Timer_Tick;
}
}
}
#endregion
#region Events
public event EventHandler UserActivity;
#endregion
#region Constructor
/// Default/Parameterless SetApplicationTimeOut Constructor
public SetApplicationTimeOut()
{
KeyPreview = true;
FormClosed += ObservedForm_FormClosed;
MouseMove += ObservedForm_MouseMove;
KeyDown += ObservedForm_KeyDown;
}
#endregion
#region Inherited Methods
protected virtual void OnUserActivity(EventArgs e)
{
// Invoking the UserActivity delegate
UserActivity?.Invoke(this, e);
}
public void SetTimeOut()
{
// postpone auto-logout by 30 minutes
_timer = new Timer
{
Interval = (30 * 60 * 1000) // Timer set for 30 minutes
};
Application.Idle += Application_Idle;
_timer.Tick += new EventHandler(Timer_Tick);
}
#endregion
#region Private Methods
private void ObservedForm_MouseMove(object sender, MouseEventArgs e)
{
OnUserActivity(e);
}
private void ObservedForm_KeyDown(object sender, KeyEventArgs e)
{
OnUserActivity(e);
}
private void ObservedForm_FormClosed(object sender, FormClosedEventArgs e)
{
FormClosed -= ObservedForm_FormClosed;
MouseMove -= ObservedForm_MouseMove;
KeyDown -= ObservedForm_KeyDown;
}
private static void Application_Idle(object sender, EventArgs e)
{
_timer.Stop();
_timer.Start();
}
private static void Timer_Tick(object sender, EventArgs e)
{
_timer.Stop();
Application.Idle -= Application_Idle;
MessageBox.Show("Application Terminating");
Application.Exit();
}
#endregion
}
}

I have implemented the code but unsure whether it is the right way of doing it.

 

Any leads would be appreciated. Thanks for going through the post and STAY SAFE!
