Windows Mobile 6 Unattended Mode

Hi,

I recently read an article (and video) on MSDN about making a Windows Mobile
device enter unattended mode instead of suspended mode when the the
standby/power button is pressed. This allows applications to continue to run
instead of effectively pausing them when the screen is turned off. This is
achieved by PInvoking PowerPolicyNoti fy.

I have been developing a WM (PocketPC) application for a while now and
testing it on my HTC Touch Dual but it has never paused when turning the
screen off. Am I right in saying that there must be some software supplied
by HTC or Orange (my service provider here in the UK) which is calling
PowerPolicyNoti fy already? Or is there a registry setting that controls this?

Also relating to unattended mode, the article I read suggested that the
audio subsystem does not work in unattended mode but the audio player
supplied as part of my HTC Touch Dual still plays when I turn the screen off.
Does anyone know why?

I'm using .NET Compact Framework 2.0 and C#, my HTC Touch Dual is running
WM6.1.

Apologies if I've posted this in the wrong place, I can't find a managed
newsgroup for mobile (.NET Compact Framework) development.

Thanks in advance,

Colin

Hi,

It might be possible that the device itself is calling it for your
self, not only that as this is a phone you cannot turn off the audio
when the screens is off, if you do so either you lose the calls when
the screen is off or you have to have the screen on all the time.

There is a NG for compact framework that is very active, it's

Hi, I am making my first Windows Mobile app, a simple countdown timer for my Windows Mobile 6.1 Pocket PC (in C#). The alarm works fine in general. However, if I've let my Pocket PC sit idle for more than 1 minute and the display turns off, then the alarm will not sound until I press the "power" button to wake it back up. This makes the timer pretty much useless: for example, what if I want to be woken up after a 30-minute nap? When I...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
