Whether Software Developer is in your job description or not, you should understand the difference between 32-bit and 64-bit. Read on for a clear answer.

Xojo 2017 Release 1 includes support for running and debugging 64-bit apps right from the IDE for macOS and Linux. Windows support is noticeably absent. Why? The answer is a bit complicated but interesting.
Comments closedUsing the Remote Debugger means that you can run Xojo apps on the Pi for testing and development without have to first purchase a Xojo license.

Comments closedWant a quick and easy way to send notifications to your devices (iOS, Android and web browsers) from Xojo desktop and web apps? Perhaps you want to send a notification if a purchase is made, an error occurs or a long process has finished. If so, the free Pushover web service might be what you need!

Comments closedSooner or later your app will need to work with files, maybe to save the data generated with the app itself, to open the files created with other apps or because is the main purpose of the utility you are working on. Xojo gives you the class FolderItem fully loaded with a useful bunch of properties that allow you to examine the attributes of any file; for example, the creation or modification of dates, the file path (in several formats), if the file is an alias, etc. The FolderItem class also gives you the methods to do a lot of file operations without effort.
Comments closedWith all the Retina/HiDPI work done in the past few years, we’ve had to add some new features along with it. One of these newer features is the Graphics ScaleX and ScaleY properties. For the purposes of Retina/HiDPI, the scale factor is used when converting user space coordinates to backing store coordinates. While mostly integral on MacOS (unless originating from some code that’s probably not ours), it can vary on Windows, and perhaps arguably mostly fractional. This is because Windows allows you to set DPI scales at 125%, 150%, etc. So when dealing with fractional scales there are a few things to watch out for:
- Rounding issues
- Anti-alias effect
While the framework takes care of rounding issues, for the most part, the secondary issue of anti-aliasing is up to you.
Comments closedXojo is a modern, powerful programming language with an IDE that simplifies all kind of tasks related your project creation and deployment. One such helpful feature is the UI layout design; you can find it under the Library Panel, it’s a meaningful collection of graphic classes (Controls) ready to use in our apps. Probably one of the first and most used controls in apps design is the TextField, TextField simplifies the way an app can get the input from the user. Let’s see its main properties and how this control behaves when used in Desktop, Web (WebTextField) and iOS (iOSTextField) apps!
