Re: [perl-win32-gui-users] Service with Trayicon and Popup-menu

[Jason P. <jp...@un...>]

Geoffrey, j.,

The problem is not that the program is running as a service, but that =
the
Win32::GUI::Dialog() function *DOES NOT RETURN* until told to do so... =
Minor
problem for a service :).=20

Geoff, you are right about Win32::GUI::DoEvents()! DoEvents() runs a =
single
cycle of messages off the windows message stack, and then returns =
control to
the calling routine. This can be used to nicely tell the message stack =
"Hey,
I've got like 5 seconds, make it quick" versus "Yo, message stack, what =
up"
and chatting for an hour. I've used it in the past as a method to
"demi-thread" and application (an IRC-type administrative bot) for =
socket
communication and GUI control. Ok, so if the message stack gets VERY =
VERY
LONG it might choke the service a bit, and if the service is performing =
some
ridiculously heavy task, the menu isn=92t going to respond at all, but
DoEvents is your function of choice without going into threading and =
message
passing. (Which doesn=92t sound hard... but its not the worlds prettiest =
site
in Win32::GUI, even if it does work nicely [THX ROB ;)])

I'm not exactly clear on how you go about adding a tray icon with a
Win32::Daemon since, if I understand correctly, the daemon runs in the
background before a user is even logged in (which I'd assume is also
the reason the daemon can't call Win32::GUI::Dialog).

Is it possible to call Win32::GUI::DoEvents() in your daemon when it's
needed and stop the loop that's calling it when your daemon is going
back to acting like a daemon?

Or would it make sense (it does to me, but then I'm a UNIX person by
background) to have a completely separate process that handles user
interaction with the daemon, which itself just runs in the background
with no UI of its own?
