1 CommentCategory: Database
All posts related to using databases.
Using databases with web apps is not much different than using them with desktop apps, but there are a few things to keep in mind. The most important thing to note is that a web app allows multiple users. This means you’ll want your database connection to be unique for each user that connects to the web app, rather than global to the app itself (as is common in desktop apps). The simplest way to ensure this is to create the connection to your database in the WebSession.Open event handler, saving a reference to the connection as a property that you add to WebSession.

Available since 1998, Xojo was one of the first languages to use Automatic Reference Counting (ARC), something that other languages such as Swift and Objective-C now use. Xojo is type-safe and fully object-oriented making it easy to learn and use, but it also has advanced features such as namespaces, extension methods, exception handling, introspection, delegates and more.
