Follow-up comment from the OP:
VB
Private Sub SystemEvents_SessionSwitch(ByVal sender As Object, ByVal e As Microsoft.Win32.SessionSwitchEventArgs)
 Try
  Select Case e.Reason
    Case Microsoft.Win32.SessionSwitchReason.SessionLock
      ClientStatus(MBSMessage.ClientStatus.Locked)
      UserLockUnlockSettingUPdate(MBSMessage.ClientStatus.Locked)
      timerMessageRecurrance.Stop()
      Exit Select
    Case Microsoft.Win32.SessionSwitchReason.SessionUnlock, Microsoft.Win32.SessionSwitchReason.ConsoleConnect, Microsoft.Win32.SessionSwitchReason.RemoteConnect
      timerMessageRecurrance.Start()
      ClientStatus(MBSMessage.ClientStatus.Login)
      UserLockUnlockSettingUPdate(MBSMessage.ClientStatus.Login)
      Exit Select
    Case Microsoft.Win32.SessionSwitchReason.SessionLogoff
      ClientStatus(MBSMessage.ClientStatus.LogOff)
      timerMessageRecurrance.Stop()
      Exit Select
    'added this logon case for DISPLAY_ALERT_DELAY_DURATION feature to work
    Case Microsoft.Win32.SessionSwitchReason.SessionLogon
      timerMessageRecurrance.Start()
      ClientStatus(MBSMessage.ClientStatus.Login)
      Exit Select
    Case Microsoft.Win32.SessionSwitchReason.RemoteDisconnect
      ClientStatus(MBSMessage.ClientStatus.LogOff) timerMessageRecurrance.Stop()
      Exit Select
  End Select

I already tried the following :

Private Sub SystemEvents_SessionSwitch(ByVal sender As Object, ByVal e As Microsoft.Win32.SessionSwitchEventArgs)
Try
Select Case e.Reason
Case Microsoft.Win32.SessionSwitchReason.SessionLock
ClientStatus(MBSMessage.ClientStatus.Locked)
UserLockUnlockSettingUPdate(MBSMessage.ClientStatus.Locked)
timerMessageRecurrance.Stop()
Exit Select
Case Microsoft.Win32.SessionSwitchReason.SessionUnlock, Microsoft.Win32.SessionSwitchReason.ConsoleConnect, Microsoft.Win32.SessionSwitchReason.RemoteConnect
timerMessageRecurrance.Start()
ClientStatus(MBSMessage.ClientStatus.Login)
UserLockUnlockSettingUPdate(MBSMessage.ClientStatus.Login)
Exit Select
Case Microsoft.Win32.SessionSwitchReason.SessionLogoff
ClientStatus(MBSMessage.ClientStatus.LogOff)
timerMessageRecurrance.Stop()
Exit Select
'added this logon case for DISPLAY_ALERT_DELAY_DURATION feature to work
Case Microsoft.Win32.SessionSwitchReason.SessionLogon
timerMessageRecurrance.Start()
ClientStatus(MBSMessage.ClientStatus.Login)
Exit Select
Case Microsoft.Win32.SessionSwitchReason.RemoteDisconnect
ClientStatus(MBSMessage.ClientStatus.LogOff)
timerMessageRecurrance.Stop()
Exit Select
End Select

Yuck, that's obviously the other C#, known as VB :)

That's nice and well. You can handle SessionSwitchEvents. But without some component ever raising the event this will do nothing.

every session is raising but logon event is not raising, that is what bothering me.
please do let me know if any other way is der to raise logon event.

Thanks,
Ram
