Lockdown and Idle events

[Guest]

Hi all
I would like to run my app (C# 3.0 Win application) on the following XP
pro/home events:
Enter and exit idle mode (peripherals don't get input for few minutes)
Station lockdown and entrance (winkey + L or alt+ctrl+del -> lock computer)
I can create windows C# service that periodically check (if its possible)
the different situations, but I don’t want to add load to the station.

Please advice,

Sharon

FYI i found some win32 entry :

Private Declare Sub LockWorkstation Lib "User32.dll" Alias
"LockWorkStation" ()

Private Declare Function OpenDesktop Lib "user32" Alias "OpenDesktopA"
(params) as Long

Private Declare Function CloseDesktop Lib "user32" (ByVal hDesktop As Long)
As Long

I will try to use them.
Thank you
Sharon
