How to determine needed permissions from JavaObject code
Now and then there are JavaObject code snippets posted in the forum. Usually there are permissions required listed together with the code, but not always. Which could be because none are needed. This is how one determines what permissions are required by a section of JavaObject code.

Inputlist with images
For one of my project, i needed an input list that includes images and i was thinking of using clv for that, but i really wanted to use the native input list so with CSBuilder it is very simple to archive.

Client IRC (Internet Relay Chat)
With the IRC Client complete the work started with the IRC Server. As already explained is a Basic version, to give only an idea of how it works, but it is not complete with all the commands, and does not interpret all the server commands. But it is fully functional. Limits are imposed, such as the possibility of entering only one channel at a time. But all that is missing can be inserted. The Server can be found in these two links: For B4A e for B4J

B4ATutorialPDF
Create PDF''s on an Android devices & send them to a B4J app
There are a lot of libs about creating pdf''s. With Erel''s example (https://www.b4x.com/android/forum/threads/printing-and-pdf-creation.76712/) how to create pdf''s on Android devices (it''s a build in function of Android 4.4+) I came to the idea to use a phone/tablet to create pdf''s and send them to a B4J app. How it works: B4A -> create 100 PDF''s -> convert to byte array -> AsyncStream -> B4J -> store PDF''s as files What is it good for? - Create PDF''s for free - usage of x devices as workers to create thousands of PDF''s very fast (100 takes about 6 secs) - you can use Firebase Messaging to trigger a device (not included in the example) to retrieve data form a server-db and create PDF''s from it. Send it back to the server (via OKHeetUtils or sockets), mail it to a customer, etc.
