Hi, use "WTSRegisterSessionNotification()" to register your window to receive the notification "WM_WTSSESSION_CHANGE" which has "WTS_SESSION_LOCK" & "WTS_SESSION_UNLOCK" parameter to identify that. Best Regards Raj

Implement the ISensLogon interface. The DisplayLock() and DisplayUnLock() methods are of interest to you.
