Mobile Development: Subclass foreign Window using injectDLL

Recently we needed to show and hide the SIP (Software Input Panel) inside a full screen Remote Desktop Mobile session.

The first challenge is to control the SIP without having a menu bar with the SIP symbol inside. To get this working you can assign a hardware keyboard button, it must be an App button, to show the SIP. See Settings>Personal>Buttons and assign “<Input Panel>” to the hardware key.

Android development: btPrint4 prints demos and files to Bluetooth receipt and label printers

This is an update to my btPrint4 android application. The app now supports ‘printing’ of files. You are no longer tied to the provided demo files. ‘Printing’ here means it sends the file as is to the printer. So, watch your step and do not send files that your printer does not understand.

btprin4_file_main  btprint4_file_selected  btprint4_file_browse

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.

Windows Phone 8: print demo for bluetooth label/receipt printers

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.
