The easiest way for you to obtain Xojo is to go to their website and download the correct installer for your system.
Download and install the software.
Note that to try Xojo out, and do many of the things in this guide, you DO NOT need to buy a license. The only time you will need to buy a license is if you want to build a stand alone executable program.
For this guide that will NOT be required.
So go ahead and download the latest version and install it.
Welcome to The Definitive Guide
Here I intend to guide you through Xojo ; how to use the IDE and how to write more effective code with it.
This guide should be treated as a 2025 update to Matt Neuburg’s excellent REALbasic : The Definitive Guide. While that book is nearly 25 years old much of what was written in it still applies to Xojo; REALbasic’s modern successor.
However in the intervening years many things have changed. Matt originally only had Desktop & Console applications to try & describe. Now Xojo targets Desktop, Console.Web, iOS & Android. And there are inherent differences between those project types and how they behave when executed.
I’ll do my best to point out similarities as well as differences.
