We’re pleased to announce the launch of beta testing for 4D v18 R3! So what advances do this feature-release have to offer?
- We strive to evolve the 4D language for a seamless and intuitive coding experience. For this, the 4D language has taken a giant leap with the introduction of Classes.
- Never be at a loss when trying to determine which operation causes a server to be slow. A new command is at your disposal to help you detect operations exceeding a specified duration.
- ORDA also has its shares of features, for example, two new member methods. The first allows you to extract data from an entity selection, and the second enables you to immediately get refreshed data from the server.
- More than 40+ standard actions have been added to the 4D write Pro interface, extending development possibilities even further.
- As for 4D for iOS, 40+ ready-to-use templates are now at your disposal (accessible from the project editor.) A single click is all it takes to install the template of your choice.
- And much more (see below).
We’re pleased to announce that 4D v18 R2 is now available!
Here’s a sneak peek of what’s in store for you:
- The Form Editor‘s UX has been greatly enhanced to instantly let you know when views are used and provide many actions to simplify form design (add view, delete a view, select all objects in the view, etc.). The cherry on top? A redesigned layout and flat icons for a fresh overall look.
- Full control over your work area is available to prevent an application’s interface from being covered by the macOS dock/menu or the Windows taskbar. And a list box builder is up and running to simplify your life when building entity selection list boxes.
- 4D Write Pro ships with additional features, for example, managing formulas inside your documents and the ability to delete pictures in a snap.
- What about your 4D View Pro documents? There’s now a whole set of commands to help you add and remove rows and columns, as well as define their size, visibility, and header labels.
- Plus, the first part of a feature to receive emails is accessible, allowing you to locally download emails and remove them from your email server.
And more awaits you.
Although 4D Summit 2020 had to be canceled, it would be a shame to waste all of the content and demonstrations from multiple speakers. This year, 4D Summit has gone digital … FREE and accessible for the entire 4D Community! All you need is an internet connection and a browser to discover new product announcements in technical keynotes and explore 40+ breakout sessions. There’s even a special session by Laurent Ribardière – President and Founder at 4D SAS, in which he gives an exclusive peek into the future of 4D.
One of the most interesting features delivered with 4D v18 was remote datastores. They opened a whole world of possibilities and in this blog post we’ll show you a practical use case:
Sharing the source code of 4D components lets you customize them and make them your own! With project databases and the ability to share an application’s source code via a source control system, we’ve converted our 4D internal components into project databases and pushed the source code to the 4D GitHub account. It’s open to everyone, all you need to take advantage of it is an account on Github. Why did we do this? To make your life easier by keeping track of changes and modifications to both code and forms.
In a previous blog post, we showed you how to get started with the 4D REST server. We walked you through different CRUD operations using Postman and pointed you to the full REST documentation. In this blog post, We’ll explain how sessions work in 4D. This understanding will ensure that you’ll be able to build a session-based authentication system using the 4D REST server.
Want to retrieve data that isn’t available via REST or Web Services? What if it’s only available on a website? The data is easy enough for a human to read, but reading HTML data with a programming language isn’t so simple. Some developers try to use Position and Substring, others try Regex, but it’s unpleasant and time-consuming. A very different approach is to convert the HTML into an object and get the data via object notation. Table rows are handled as collections and are easy to loop through!
This blog post describes how to use this approach and provides some handy tips.
