How do you format and organize your code? I’m here to tell you that your way is wrong and my way is right 🙂
Comments closedAs defined on Wikipedia, Automatic Reference Counting (or ARC) is a “memory management enhancement where the burden of keeping track of an object’s reference count is lifted from the programmer to the compiler.”
With object-oriented programming, each new object you create takes up space in memory. This memory needs to be managed somehow. In the beginning, this management of memory was left entirely to the programmer, such as with C++ or originally with Objective-C.

Comments closedDid you know that you can create scripts to control the Xojo IDE? And many of these scripts could be real time savers.
Comments closedFrom 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”.
Comments closedBjorn 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.
