Whether 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.
If 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.
While 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

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.
