Blog about the Xojo programming language and IDE
These days everyone has a great idea for an app. Maybe you have an idea that would save you time at work, or maybe you’ve been thinking of an app that would automate something you do at home. Not sure where to start? One of your first steps is choosing a development tool that is right for you and for your project.
Here are five questions to guide your decision:
Comments closedSome of the most interesting web services you can use with Xojo through remote API calls are related to Artificial Intelligence. There are many different APIs provided by the main players in the AI sector, but IBM’s Watson is by far the most well known.
I’m going to show you how to connect to IBM’s Watson services with REST APIs and how to use them with Xojo projects to identify images. This is just one example, of course, of the many ways to utilize Watson and AI in your Xojo apps.

Comments closedWhether you are using Xojo to create your very first application or if you are coming from other languages, like C# or VisualBasic, customized UI controls are probably one of those things you have in your to-do list. For multiplatform Desktop apps, you will find that the Canvas class offers everything you need. In order to show you how easy it can be, follow this tutorial to recreate the ImageWell UI class control, provided by default in the Xojo framework. Our customized ImageWell will be able to proportionally display any JPEG file dropped by the user on the control, centering it on the available surface.
Comments closedIf you spend enough time trying to predict the future, you learn that the more variables there are, the more difficult it becomes to determine a future. Take the weather for example. It’s not hard to predict tomorrow’s weather because there’s not much that will change over the next 12 hours or so. Try to predict the weather 7 days from now, 7 months or worse, 7 years from now, and your results will begin to vary dramatically.
This is certainly the case when it comes to writing apps. The bigger any one particular feature is, the more variables there are that affect it and thus the more difficult it becomes to predict how long it will take to finish. You don’t have to work in the software business very long to figure this out. Like most people in the software industry, we’ve been trying (with varying degrees of accuracy) to do this not just for our own internal planning but because we know you want, and need, to know as well.
Comments closedWhile working on an app I found myself in an unexpected situation when a piece of code that had been working fine began to throw an OutOfBoundException. After a bit of debugging I found that the culprit was the length of an array passed to the AddRow method of a ListBox instance.
You can call into Win32 APIs (aka WinAPI) to use methods and properties that are not built into the framework by using the Declare command. To create a Declare statement you first need to track down the API you want to use using Microsoft’s documentation: Microsoft Developer Documentation.
