Hi, Guys Scanning through the forum it appears that (using V4B 8.3+) it is OK to define global variables in the Starter Server (in the sub Process_Globals) as it will not be removed by the OS whilst the App is running, Question - is that correct? Also, would I be safe to store global variables...

I develop the XUI version of the ScrollView2D library that created @Informatix. I did not base myself on its code but developed everything from scratch. It is still unripe, but it works well and is not very heavy. Clearly for iOS already the native ScrollView is 2D as well as for Desktop...

Hi, I am trying to write XOR encoding/decoding for B4X (I need to use it as a light weight and fast encoding/decoding cross plateforme solution with B4I, B4A, B4J and Lazarus/FPC). I know XOR is not the best/strongest encryption solution but it should be ok for my needs). The following code...

Hi Erel, I have some suggestions about B4X and, given that for necessity I had to move away from B4A/B4I and jump ship to Ionic and soon Flutter, this is my feedback I can offer so that B4X could be a valid alternative to those environments especially for many of us who are a 1 man show and...
