Thanks so much! This is really helpful.@RoyalArt As you have seen B4X syntax is similar to VB.NET. Pay attention to the events and functionality that exists inside B4X. When you declare a variable you can see the associated methods for each library. You can also access these by typing Sub (press spacebar then Tab) to learn about the many events. Members of the community always try to help as much as possible, and you click "like" as a sign of gratitude and respect for the time being spent to help you progress with your private projects.
