Build All The Things

As 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.

Guest Post: Part 1, Transparent Label Tip for Windows

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.  Wayne’s 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.

How I learned to stop worrying and love the debugger

Since 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.

Take A Core Dump: What to do when your app crashes on Linux

With 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.

Guest Post: A Few Little Xojo Code Performance Tips by Eric Gibbon

Eric Gibbon has been using Xojo to develop bespoke cross-platform applications for Mac and PC and for the web for 15 years. He lives in Stamford, England, and is an active member of the Xojo UK User Group.

There’s an old programmer’€™s saying: If it works, leave it alone.€ But sometimes we have to go back to code that works to make it go faster, because it’€™s too slow.

Over time I have picked up some tips on how to get better performance from Xojo code. I have used these tips to improve old code running on all platforms and have seen big improvements. They are quick and easy to do.

Time for a Reminder to Backup Your Data

If you work with computers, having backups of your data is essential. This particularly came to light recently with people testing out Apple Music and discovering that it could make a mess of your iTunes library. In fact, this happened to me!

But “luck favors the prepared” and I had backups, so this Apple Music glitch only proved to be an annoyance and not a catastrophe.

In my case, I just restored my iTunes library from my Time Machine backup. But I know far too many people that don’t even have any type of backup system in place. I’m here to help.
