Blog about the Xojo programming language and IDE
Wikipedia defines Code Refactoring as:
the process of restructuring existing computer code â changing the factoring â without changing its external behavior. Refactoring improves nonfunctional attributes of the software.
Did you know that Xojo has a bunch of refactoring features that can help make this process more efficient?
The TSA was recently in the news for paying tens of thousands of dollars for a seemingly simple iPad app to direct people to different security lines. Now we obviously don’t know everything the app does, but it sure seems like it would be pretty straightforward to make such an app, especially using Xojo.

Comments closedYou don’t need to hook up your Pi to a physical display, keyboard and mouse. You can set up VNC on the Pi so you can remotely connect to it.
My Raspberry Pi 2 sits on my desk next to one of my speakers. It’s not hooked up to any display. I use a combination of SSH, SFTP and VNC when I need to work with it.
Comments closedIf you work at a desk all day, you should be thinking about your ergonomics.
Being comfortable while you work is important. It enables you to concentrate better, but more critically, it prevents you from injuring yourself. From Musculoskeletal to vision and hearing problems, yes, it is quite possible to injure yourself while working at a desk!
Comments closedI recently had someone ask me how to reorder the columns in a SQLite table. As you may be aware, the SQLite ALTER table does not have a lot of functionality compared to other databases and it certainly doesn’t have a way to do this.
Comments closedSometimes you’re going to need a data structure that is an array of classes and you’re going to want to sort them. The standard array Sort method can only sort simple types (Text, Integer, etc), so what do you do?
The traditional technique has been to use SortWith. You create a separate array of a simple type, populate it and then sort the temporary array using SortWith to sort the class array.
But there is an even slicker way to sort that was added in 2015 Release 3. You can now create your own custom comparison method and use that to sort the class. This custom method returns 0 if the values to compare are equal, a positive if the first value is greater than the second, and a negative value if the first value is less than the second.
Comments closedOn Monday February 29th, the Raspberry Pi Foundation announced the new Raspberry Pi 3. This updated Pi has some significant improvements over the Pi 2, including:
That last bullet point is notable because it means that Xojo is also fully compatible with the new Raspberry Pi 3!
