Question

I am planning a develop an application, which starts up with windows (a service perhaps) and silently records User’s Login, Logout and System Lock/Unlock events..

It would be awesome if someone can give a me a tip to record their total idle time (the time where no system activity was performed by user)

I am looking for a pre-developed library or something which can help me smoothly complete the project.

try it out the below code….

private enum WTS
{
        CONSOLE_CONNECT = 1,
        CONSOLE_DISCONNECT = 2,
        REMOTE_CONNECT = 3,
        REMOTE_DISCONNECT = 4,
        SESSION_LOGON = 5,
        SESSION_LOGOFF = 6,
        SESSION_LOCK = 7,
        SESSION_UNLOCK = 8,
        SESSION_REMOTE_CONTROL = 9
 }

protected override void WndProc(ref System.Windows.Forms.Message m)
{
    switch (m.Msg) {
        case WM_WTSSESSION_CHANGE:
            switch (m.WParam.ToInt32) {
                case WTS.CONSOLE_CONNECT:
                    //MessageBox.Show("A session was connected to the console session.");

                    break;
                case WTS.CONSOLE_DISCONNECT:
                    //MessageBox.Show("A session was disconnected from the console session.");

                    break;
                case WTS.REMOTE_CONNECT:
                    break;
                //MessageBox.Show("A session was connected to the remote session.");
                case WTS.REMOTE_DISCONNECT:
                    break;
                //MessageBox.Show("A session was disconnected from the remote session.");
                case WTS.SESSION_LOGON:

                    break;
                //MessageBox.Show("A user has logged on to the session.")
                case WTS.SESSION_LOGOFF:
                    //MessageBox.Show("A user has logged off the session.");

                    break;
                case WTS.SESSION_LOCK:
                    //MessageBox.Show("A session has been locked.")

                    break;
                case WTS.SESSION_UNLOCK:
                    //MessageBox.Show("A session has been unlocked.")

                    break;
                case WTS.SESSION_REMOTE_CONTROL:
                    MessageBox.Show("A session has changed its remote controlled status. To determine the status, call GetSystemMetrics and check the SM_REMOTECONTROL metric.");
                    break;
            }

            break;
    }

    base.WndProc(m);
}
