Does anyone know how to capture PC locked events?

[Rigel]

I've tried looking at SystemEvents but I don't see anything that has to do with capturing an event if the user locks the PC. Does such an event handler exist in C#?

Thanks

Looks like it:

using System;
using Microsoft.Win32;

public class App
{
     static void Main()
  { 

     SystemEvents.SessionSwitch += SystemEvents_SessionSwitch;
     Console.ReadLine(); // block main thread
// !! detach the eventhandler when the application terminates, or you will
leak a handle.
     SystemEvents.SessionSwitch -= SystemEvents_SessionSwitch;
  }

     static void SystemEvents_SessionSwitch(object sender,   SessionSwitchEventArgs e)
  {
    if(e.Reason == SessionSwitchReason.SessionLock)
        {...}
  }
}

}

Awesome! Thank you, I cannot believe the answer was right under my nose. Still having some problems with this as the events do not get generated but I'm taking a look at the website link you gave for more clues. I think I'll find an answer soon. Thank you!

Did you every solve your issue of not capturing the events. I am having the same issue.

It has been a long day so I might be missing something. I will take another look in the morning.
