Autologoff from C# app

Hello-

I want to adapt the code here to present my program's logon dialog box after a period of inactivity.

This works, except that instead of Application.Exit(), I want to present my Logon form. I can't figure out how to kill the EventHandler from firing once my form loads.

ActivityMonitor.ActivityMonitor _am = new ActivityMonitor.ActivityMonitor();
_am.WarningMinutes = 0.9;
_am.MaxMinutesIdle = 1;
_am.Idle += new EventHandler(am_Idle); 

void am_Idle(object sender, EventArgs e)
{
    Application.Exit();
}

Open in new window

If I place anything other than Application.Exit() in this location, mulitple instances of my form are created, no matter what I do to try to dispose of the EventHandler.

Any ideas/suggestions are welcome

#1 - there's no enable property
#2 - oddly, I get the same result (the application quits, but then multiple instances are spawned when it reopens)

try one of these options.

Option 1:
void am_Idle(object sender, EventArgs e)
{
    _am.Idle -= new EventHandler(am_Idle); 
    //Start a new instance of the application
    System.Diagnostics.Process.Start(Application.ExecutablePath);
    //Close the current instance
    Application.Exit();
}

Option 2:

bool blnRestarting = false;

void am_Idle(object sender, EventArgs e)
{
   if (blnRestarting)
       return;
   blnRestarting = true;
    //Start a new instance of the application
    System.Diagnostics.Process.Start(Application.ExecutablePath);
    //Close the current instance
    Application.Exit();
}

nvm ksrsrinivasan, that works just fine.

Accidentally had moved the instantiation of the EventHandler inside a foreach loop. Ouch.

Thanks,
