From time to time we see the issue raised where floating point values are not exact like we can write in the code editor or on paper. Usually the confusion or complaint is worded like “I can’t get my double value to be precise like in the string” or “It’s not the same as I get doing it by hand”.

Bjorn at Einhugur has created a bunch of tutorials for projects you can create using Xojo and a Raspberry Pi.
Comments closedAs you may have heard, Xojo 2015 Release 3 added the long-awaited ability to create 64-bit apps. And it also added the ability to create Raspberry Pi 2 apps (Linux ARM). This now means there are lots more apps that can get built.
Comments closedRead Part 1 for a simple solution to set up a transparent label in Windows.
Xojo has three default project types on Windows (four on OS X with iOS).
Wayne Golding has been a Xojo developer since 2005. He operates an IT Company Axis Direct Ltd www.axisdirect.nz which primarily develops applications using Xojo that integrate with Xero www.xero.com. Wayneâs hobby is robotics where he uses Xojo to build applications for his Pi2 often implementing IoT for remote control.
When developing for Windows, it’s not immediately clear how to set up a transparent label. If you change the background colour of your Window, you could end up with that ugly gray label. And of course I always forgot to set the transparency until after the debug run. But I’ve found a simple solution.
Comments closedSince we are all good programmers we never make mistakes, right ? 🙂
But for those times when you write some code and you just can’t figure out why its not behaving, there is always the Debugger!
The best part is the Debugger is very easy to use and it can help you sort out a lot of common issues. Its covered in the Xojo User’s Guide, specifically see the Using the Debugger section.
Comments closedThe first classes in the new Xojo Framework have been available for all project types since Xojo 2015 Release 2. Here are some of my favorite features.
Comments closedSince the release of Xojo for iOS, people have been asking if Xojo apps can be listed in the App Store.
The answer is simple: Absolutely.
Comments closedWith many things in life, more choices means more freedom of expression. We can pick and choose what we like personally as a way to express ourselves. Such is the world on Linux. The myriad of different Linux distros along with all the different Desktop managers and Window managers available are daunting. While more choices is nice (in general anyway), it can also cause more confusion. As a cross-platform developer, you’re probably aware that every operating system has their own way of dealing with crashes and crash reports. On Linux this is no different, but it is more confusing because not every Linux distro plays by the same configuration. This blog will answer some fundamental questions you may have about what happens when your application crashes on Linux.
Comments closedI’ve been working with JSON in the new Xojo framework quite a bit lately and wanted the ability to format the JSON text so it is more readable.
A little Internet research turned up a set of classes for .NET (in C#) that can do this. I took a few minutes to port these three classes over to a single Xojo class that can format JSON for you.
