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);
}
