In software development, efficiency and user experience are paramount. One powerful technique that can help achieve both is the use of type casting combined with iteration. By iterating through controls and casting them to specific types, developers can dynamically manipulate user interface elements, resulting in more responsive and interactive applications. In this article, we will explore the concepts of type casting and iteration within Xojo applications. We will break down a practical example to demonstrate how these techniques can be used to optimize form handling and enhance user interactions.

Comments closedA recent blog post, A Beginner’s Guide to Handling Text Files in Xojo, covered the basics of text file handling in Xojo. This post delves into advanced techniques for reading and writing large files in chunks. This method is crucial for managing large datasets efficiently, minimizing memory usage, and maintaining application performance.
1 CommentThere are many ways to develop with Xojo and use Database Servers. You might be working on a multi user Desktop Application that stores data in a Database. Or you’re creating a multi user Xojo Web Application that needed to be scaled up to a couple of running instances – and use a Database for data storage. Or maybe you’ve written a mobile application that connects to a Backend REST API – again possibly written in Xojo (e.g. with the open source Express, or with Xojo Web).
Comments closedAs developers, we often need to work with text files. This could be for reading configuration settings, parsing log files, or generating reports. Text files are a common part of software development, and knowing how to access and manipulate them is important for building strong and flexible Xojo applications. In this article, we will make use the key Xojo classes and techniques for working with text files. We will start by looking at how to read the contents of text files using the TextInputStream class. You will learn how to read an entire file into a string and how to process the file line-by-line.
1 CommentThis is not that common of an issue, but it happens – when searching for memory leaks, remember to check any cross-referenced objects. Cross-referenced objects are, well, just that, objects that need to reference each other. For example, when “ClassA” needs to know about “ClassB”, and “ClassB” needs to know about “ClassA”. Continue reading to see how this can cause memory leaks in your projects and how to use Xojo’s WeakRef to fix it.
