Object Oriented Programming (OOP) puts in our hands the ability to create apps in a flexible and powerful way. Xojo embraces that philosophy in the Xojo language itself, allowing us to implement code in a flexible way for reuse, extension and maintainability that reduces the development cycles. One of these language tools is, in fact, common in other low level programming languages: Casting or type conversion. If you are interested in this (and you should be), continue reading and discover what it is, why you should be interested in it and how can you use it in your next Xojo app!

The last post covered optimization in general. In this post you’ll look at a specific optimization called “loop unrolling”.

Like his father, my teenage son loves video games. The single player games where you take a character through some kind of adventure are the ones I like most. These usually have a fair number of AI-controlled enemies that must be defeated. My son, on the other hand, prefers to play against other human beings. When I asked him why, he said, “The AIs are so predictable.” To prove this to me, he took over when I was having trouble defeating a particularly difficult enemy and quickly dispatched him, narrating his strategy as he went and barely being scratched in the process. My son is an elite player compared to me partially because he puts a lot more time into it than I do but also because he loves video games far more than I do.
Just as people have varying levels of skill and interest in video games, the same is true of app development. There are those that are happy to devote enormous amounts of time to learning everything they possibly can. They don’t care how long it takes. They want to have control over everything and are willing to do whatever is necessary to make that happen. I’m so glad those people exist because there’s a lot of great software that might not otherwise have been created without them. I’m not one of those people. I really want to focus mostly on what makes my application unique, abstracted from the nitty-gritty of app development.
That’s why I have always been attracted to tools like Xojo. I am a citizen developer. Of all the job titles I have had over the years, all of them in tech, none have ever included words like programmer or engineer. I do some software development but it’s just a part of my job. It’s something I do to help me in my work or to help my co-workers.

In honor of Pi Day 2018, Xojo Pi licenses will be free! Xojo Pi licenses allow you to build console apps for Linux ARM for use with Raspberry Pi 2 and Raspberry Pi 3.
Comments closedEvery once in a while we get a question or post like this one that wonders why a loop might turn into an infinite loop or why it doesn’t behave as expected and stop when the loop reaches the limit.

As developers, we often like to have things set up and configured in our own way and our favorite IDE itself, Xojo, is certainly no exception. Xojo allows you to customize it in lots of way but today I want to talk about theming the IDE, or specifically the code editor.
Xojo has always had the ability to customize colors of tokens in the code editor. For example, you can open up Xojo’s Preferences and change the colors of keywords, strings, comments and much more, as well as the font and font size. Other than making things look pretty, there are practical reasons for doing all of this. You may find certain themes are easier on your eyes, especially as you age. Or you may want to have one color scheme for daytime, such as a light background with bright colors for the tokens, and a different color scheme for late night coding, such as a dark grey background with more subdued token colors.
Comments closedLast week the 2018 Xojo Developer Conference sold out! We are very excited about the enthusiasm for this event, and for it being held in Denver. We received the most early registrations we have ever had for XDC, the final list includes attendees traveling from 12 countries. Registration for this year is higher than that of 2015 and 2016, and there is already a growing waiting list! You can be added to the waiting list here.
Even if you aren’t able to join us in Denver for XDC this year, there are still some ways you can stay in touch with attendees, hear major Xojo announcements and leverage the content from the conference.

As the old joke goes, “There are 10 types of people, those that understand how binary numbers work and those that don’t.” Let’s get you into the “understand” group.

A wonderful perk of Xojo’s virtual office is getting to spend the day with our favorite people, and by people I mean pets.
Having a pet in your office provides a friendly, positive diversion, which is excellent for employee morale, pets can also increase productivity and their presence in the workplace has been proven to reduce stress. Pets help us working-from-home workaholics step away and take a sanity break. So take a minute and have some eyebleach on us. Meet the Xojo office pets!
Comments closedA recent thread on the forums discussed why a particular bit of code would not compile he felt the error message seemed less than helpful: “CRghtColr As Color = Color.RGBA(000,061,255,208)”.
