Hello everyone, I actually started this project just for fun about 18 months ago, but I didn’t have the skill set to get it working correctly back then. As I was learning, I kept going back to this project, and now it’s working like a charm. Yes, I could have used an LLM to help me get it...

Hello everyone, After reading the post by @Giacomo, I thought the idea was good, but I didn’t really want to sit down and create it myself. Still, I knew it would make a great app. I was on my phone at the time, so I asked Gemini to create the code for me as a B4J B4XPages solution. I wasn’t...

Hi all, I spent the last weeks building a source-code security audit with a lens for B4X — B4A, B4i and B4J, including the inline Java and Objective-C inside your .bas modules. I'd like to share it here, and to be told where it falls short. A word on AI, since most of us now build with it...

Creating an Excel Ribbon add-in is usually not difficult because of one line of XML. The difficult part is the complete workflow: Editing RibbonX without breaking the XML. Finding a valid imageMso icon without memorizing hundreds of IDs. Embedding custom icons correctly inside the Office file...

Hello everyone, I'm just playing about with a AWS RDS library. The problem as I see it, is that there are hundreds of features that can be wrapped into the library, it's a complete pain in the rear end. Anyway, I'm currently integrating the very basics, everything is apparently working great...

Hello everyone, I've been playing around with Llama (my first attempt failed miserably, so I scrapped it) and here are the results after starting all over again. The model in the video is Phi-3-mini-4k, but I find that I received much improved results using Qwen2.5_14B. The latter does need at...

Hello everyone. At the beginning of this year, I came across OPC UA. At the time, I knew nothing about it, and there were only a couple of posts about OPC UA on the forum. I decided to look for libraries to wrap, but I had major problems working with them. I did find a few libraries, but they...

Hi everyone, I have a compiled B4J program that I distribute to eight users. I am distributing it with Java 11. It has been running fine on Windows 11 for all users except one. In this instance the program shows a main form startup toast message OK, but the main form won't display. I have...

I havn't been very active in the forum for a while, so here is my latest offering. Here is a B4X example which creates a widgit to display Thingspeak cloud data directly on the windows desktop. There is no icon in the takbar which is why I have included a close button. The widgit updates every...

Hi, I developed a small B4J Project for my license management. (Download). If I start the compilation to get a standalone package all went well with no error messages. After starting the installed exe in the C:\Programmfiles directory a window is flashing up shortly and thats all. I substitue...

I'm thinking about putting code on Github and using this library and my Quarts library (via a nice looking GUI and an icon in the notification area) to do everything for me synchronisation wise (which could be a bad idea). I'm not sure how many B4X developers use/upload their code to Github, but...
