Re: [Wrapper-user] Detect user login

[Leif M. <le...@ta...>]

Catalin,
    The problem is that Windows does not provide an easy way to do 
this.  When a user
logs out, the OS will send a "user logged out" signal to all running 
processes.  The
Wrapper traps that and reports it.   This is done because most 
applications want to shut
down when the user logs out.   There is no such signal when a user logs in.

    Starting with version 3.1.1, you can call WrapperManager.getUser or
WrapperManager.getInteractiveUser to find out who is logged in at any given
time.  This is operation does require a bit of processing as it is done 
by scanning
the registry.  You would have a daemon process that would call it ever 
10 seconds
or so, then stop once a logged in user was found.  The loop could then 
be restarted
if the logged out signal is detected.
    The feature was actually added in version 3.1.0, but there was a 
memory leak in
the call.
    Due to a couple other bugs however, I would suggest using 3.1.2.  
That version
is very stable.

Cheers,
Leif
