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.

I’ve heard it several times: how can I export to PDF from Xojo? Sure, there are lots of answers pointing to a bunch of resources, including excellent plug-ins from third parties. But can you accomplish the same thing using an already available API? Yes, there is a remote API for that! The requirement is that your Xojo app will need to have access to Internet … and, of course, you’ll need to do just a bit of coding.
Comments closedViruses continue to be a big problem on Windows. As a result, anti-virus software can be a bit over-zealous about detecting what it believes to be apps that have viruses embedded within them. We have had reports over the years that apps made with Xojo are sometimes falsely identified as being infected with a virus. This sometimes occurs because the 32-bit Xojo compiler puts executable code in a location where the anti-virus software doesn’t expect to find it. We’ve seen this occur even when users are debugging apps from the IDE. Fortunately in that case, there’s a fairly easy solution.
Comments closedAdmit it – this is one of those questions that, sooner or later, arise to every Xojo newcomer: How can I add new UI controls to the Window at runtime? And if you are considering this too, then the good news is that the answer is more simple than you probably expect… sitting right there on the Inspector under the Attributes tab. Yes, this is all about the Control Set!
Comments closedThe Xojo community is vibrant and active, with all kinds of clever, open-source software being created for iOS, desktop, web and Raspberry Pi. By my latest count, there are at least 80 open-source projects for Xojo on GitHub and other places!

Of course you want an iMac Pro! But do you really need one for your development work? Most of the iMac Pro videos and reviews seem to focus on video and audio editing, which are certainly tasks that make use of the many cores that are available (8-18).
But software development is also a Pro task. What benefits does an iMac Pro bring to a software developer?
Typically most people will opt for a computer that probably has four cores such as found in the i5 and i7 series. These are used in the popular Macbook Pro and iMac models, for example. Four cores sure sounds like a lot so why would a developer need more?
Comments closedMany years ago, the Window Functionality Suite (WFS) library was created by Aaron Ballman. This library was a collection of Win32 Declares (and a few other things) for accessing Windows-specific functionality that was not directly provided by the Xojo framework.
WFS is still available on GitHub, but it has languished over the years. For example, it has lots of legacy code in it for older versions of Windows that is no longer needed since Xojo only supports Windows 7 and later. WFS is also not really compatible with 64-bit projects since the Declares mostly assume 32-bit or bust.
To that end, I’ve started a new open-source project called WinAPILib that is now available on GitHub.
Comments closedThe other day I saw this article on Dev.To: A Universe in One Line of Code with 10 PRINT
It talks about how you could make a maze-like structure on a Commodore 64 with just this one line of code:
10 PRINT CHR$(205.5+RND(1)); : GOTO 10
The author then goes on to show you how you might do something similar using Python and pygame.
I love all things retro and this seemed like fun, so I thought I would whip up the same thing in Xojo.

In today’s world, the only way to be sure you are reaching all your potential customers is to target multiple platforms. But cross-platform development is crazy-hard, right? Perhaps, if you are using tools like Java, Qt, Delphi or Xamarin it certainly can be. But with Xojo, cross-platform apps are simple to create.
In fact, Xojo lets you easily cross-compile desktop apps for Windows, macOS, Linux and Raspberry Pi. Plus, you can use the same Xojo language to create web and iOS apps too (Android coming soon!).
Comments closedIf you are just starting the development of your first web app you may be wondering if you need to get a Xojo Cloud server right away. In most cases, the answer is no. You can develop your application on your own computer and sign up for a Xojo Cloud server when you are getting close to deployment and are ready to test in as close to a real world situation as possible.
There are differences of course between how a web app will execute on your computer with a single user (you) versus on a server that is anywhere from hundreds to thousands of miles away with many users connected all at the same time. For the most part, you don’t have to think very much about this but there are areas where you should.
Keep the following 3 things in mind when developing without a cloud server.
