XPE SP2 Minlogon Shutdown

[Guest]

I'm trying to make my application, which is running under Minlogon, respond
to a Power Button press.

Initially I was only able to achieve a "hard shutdown" with no feedback from
my application. I reverted back to the original Minlogon component which
doesn't support the Power button and this keeps the application from shutting
down at all.

My application doesn't seem to be receiving any of the "normal" windows
power messages. What I do recieve is a message 0x218. Does anyone no where
I can get the interpretation for this message code? Or another way I can
have my application decide weather to allow the computer to shut down when
the power button is pressed.

Thanks.

mattb,

I am not sure what "normal" Windows power message you are looking for but 0x218 is the WM_POWERBROADCAST. (see winuser.h from
Platform SDK)
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/power/base/wm_powerbroadcast.asp

And you should use this message to define your application behaviour on shutdown.
Particularly, return BROADCAST_QUERY_DENY if wParam=PBT_APMQUERYSUSPEND if you want to "cancel" the shutdown.

Thank-you for pointing that out. That is the message I was looking for. My
confusion comes from the fact that my trace program "WinSight" does not agree
that 0x218 is WM_POWERBROADCAST. I wonder what else it is confused about.

Thanks.
