Windows Mobile Development and usage
Archive for the ‘Tips’ Category.
Hello
I want to summarize the role of function keys in Windows Mobile, former Pocket PC, as I got several questions each week on how to use or enable Function keys in this or that application.
Here is a simple information about how function keys work in Windows Mobile.

Hi
there are now more and more full VGA rugged devices coming. And some customers are still using Remote Desktop Mobile to run there application on the small screens. Unfortunately some of the coders use application screen layouts hard coded to QVGA (240×320). Now with a VGA capable Windows Mobile device they get weird screens on the device.
The client (Remote Desktop Mobile) sends the server information about there screen sizes. As a VGA device can display 480×640 pixels, the hard coded 240×320 applications only use a quarter of the screen. The texts are very small and more or less unreadable.

Recently I stumbled about this great article about ASCII, 7 and 8 Bit, codepages, Multi byte, Wide byte and unicode: http://www.joelonsoftware.com/articles/Unicode.html
If you ever get in trouble with wrong encoding display of chars, give this article a try to know the backgrounds.
As you know, Windows CE and Windows Mobile is always unicode except for serial and socket communication. But the truetype fonts available on Windows Mobile devices mostly support only common chars, there file size is about 600K. The file size of Arial Unicode MS is about 22MB.

Although I dont recommend this, it may be usefull if your kiosk mode app watches and manages the battery level: you can disable the low battery warning. Sometimes such hacks are hard to find, now there is one more location in internet.
In the registry find the key
[HKEY_CURRENT_USER\ControlPanel\Notifications\{A877D663-239C-47a7-9304-0D347F580408}]
This is the entry responsible for low battery warnings
Add a new REG_SZ key: “Default” with for example the text “Low Battery Warning”
"Default"="Low Battery Warning"
This entry is used to display the notification in the list of notifications in Start-Settings-Sounds&Notifications. To disable the notification itself it is not really necessary, but easier to control.
The Options entry in the registry defines which options your selected in Start-Settings-Sounds&Notifications, for example play a sound or display a user notification. Set Options to REG_DWORD=0×00 and there will be no notification when the battery goes down to 10% (depends on the device) and lower.
Here is the change in full:
REGEDIT4
[HKEY_CURRENT_USER\ControlPanel\Notifications\{A877D663-239C-47a7-9304-0D347F580408}]
"Options"=dword:00000000
"Default"="LowBattWarning"
You need to reboot the device after the change!
Only a small tipp
