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.

This is a security feature. If the Admin web page has not been accessed for some time the router disables the access completely. Router does still work, ping is OK, WLAN and WWAN connections are working, you just can not access the admin web page.
As I am running a Linux server I decided to make a hourly cron job that simply accesses the router admion web page every hour. So I can access the admin web all time without the need to cycle it’s power
I added a cron.hourly bash script to access the admin page every hour:
wget -O - -q -t 1 --user=<adminusername> --password=<yourpassword> http://<yourrouterip>
Replace the user name, password entry and ip with the ones of your router and copy that bash shell script to /etc/cron.hourly. Don’t forget to make it executable (chmod a+x ).
Update: although the above is running the web admin page could not be reached after some days. Odd security mechanism

Added a file browser activity: a class named item to hold file informations, a FileChooser class and a FileArrayAdapter. Then the needed layout files are added.

This is the description of my btPrint demo app to print demo files to portable bluetooth label/receipt printers. I already did the same app for android and now wanted to do the same for windows phone 8.
The app starts with the main screen where you select a bluetooth printer, connect, select a demo file and let it print.

As I needed a tool to test the maximum MTU size for a network, I needed a ping tool where I can define the packet size and the DF (Do Not Fragment-Flag). As I did not find such a tool, I wrote PingNG.
It is a simple tool but the code had to avoid some pitfalls.
