Widows Service Event for LogOff

[tariq_swl]

Have anybody information about Windows Service Events in vb.net.
as there already Events exist in vb.net like

onstart ()
onstop ()
onshutdown() etc.

But i need Event { on log off }.
Let me know is there such type of event exist by default?
or let me know how to write custome event in windows service i
vb.net.

Coz i need it urgently coz i m writing program of Log file maintaince.
This window service will record the user log in/log off informatio
like login time and date.
I hope to here u soon.
