Hi Guenther,
I'm facing several problems getting your example to work:
1. When opening the project, B4A complains about a missing file prodinfo.db(x)
2. I had to comment out the #CustomBuildAction Robocopy-Script that want's to copy a "..\..\Shared Files" folder, which I don't have.
After that the app compiles and starts, but when I touch any day in the calendar, nothing happens...
Thanks for your help !
