You possibly know these QRcodes that make your phone open a web site or add a contact. Unfortunately there is no such function on Windows Mobile and I just wrote a demo of such a functionality:
A demo app to show how these nifty QR barcodes are encoded to hold URLs, business cards, appointments or other data. Further on, the application shows how to use QR code reading and import or launch the appropiate application for the QRcode content. The demo uses ZXing.Net to encode text into a QRcode barcode image but ZXing or ThoughtWorks code to decode QRcode images as the latter was easier to use. Then there is a list of sample encodings to show you how to specify a vcard or SMS or others to be encoded into a readable QRcode.

After start of the app and then simply click in the type list at the top and select for example “vcard”. In the sample field you can see how a vcard is to be encoded:

Now click [decode&encode] and you get the QRcode image and the cleaned content:

Although I do not yet know a use case for this, here comes some code to make your smartdevice forms being moveable.

As default, Windows forms on mobile devices are created always as maximized forms. There may be situations, where you need a moveable form. The trick in compact framework is to use SetWindowLong with WS_CAPTION style and apply that to your form.

To enable you to experminet more with Window Styles there is another demo enabling to check all known window stlyes with a form. Be warned, setting WS_DISABLED or some other styles will make your form inaccessible.

This is a very simple application to show the values of GetSystemPowerStatusEx2 in live view.

That enables you to see how much power is drawn of the battery if you switch WiFi on or off for example.

On industrial devices you can also check the power consumption of special modules like a barcode scanner.

The attached web server offers some options to control the device or show informations about it. The web server runs on the device and enables direct control or delivers information about the device.

The project enclosed default web page offers all implemented commands. The following is a list of what is currently implemented:

• SystemInfo: get OS version info
• BEEP: let the device beep
• START: starts a process
• KILL: kills a process
• SETLED: light/unlight/blink a LED
• VIBRATE: special LED case, this sets a LED which is a placeholder for the vibrate motor
• SIP: show/hide the Software Keyboard
