I’m thrilled to announce that 4D v18 R3 is now available!
4D v18 R3 is one of the most jam-packed feature-releases ever delivered. It also marks the beginning of a very important step in the world of 4D programming with the addition of object-oriented programming.
To whet your appetite, here’s a sneak peek of what’s in store for you:
- The 4D language has taken a giant leap with the introduction of classes which allow you to write modular, reusable, and easily maintainable code.
- ORDA is brimming with new advances as well: for example, you don’t need to restart your database in order to have an up-to-date datastore when the structure is updated. Additionally, a single line of code is all you need to select rows for an entity selection.
- 4D Server’s monitoring set has been enhanced with an additional feature so you can get all operations executing beyond a specified time and other useful information.
- The development possibilities have been expanded even further with additional standard actions for the 4D Write Pro interface.
- 4D for iOS provides you 40+ ready-to-use templates. You only need a single click to download them directly from the project editor and get started making the perfect custom app for your needs.
- Run multiple web servers in a single 4D instance, take advantage of new method and components documentation, use an offscreen web area on a headless server, explore the advances we’ve brought to XPath, more options to customize 4D View Pro worksheets, this is all just a glimpse of what’s available in 4D v18 R3 for you.
When developing an application, it can be very useful to have quick access to the details of a method (e.g., an explanation of what it does, its syntax, and a definition of the parameters passed to it). This becomes even more important when using a compiled component. You can’t look at the content of the method, so you can only rely on its documentation to understand how to use it.
The Explorer’s dialog has been enhanced and documentation is now available in 4D v18 R3 for project databases.
In a previous blog post, we introduced a very important concept in object-oriented programming: Classes. Now we’ll go through another core concept: Inheritance, the mechanism that allows a class to acquire the behavior of another class.
When it comes to ORDA, 4D v18 R3 is full of good news! New member methods are at your disposal to further enhance your coding experience.
For starters, extracting data from an entity selection has been greatly enriched allowing you to build a fully customized collection with your entity selection data.
In addition, we’re providing you a way to indicate to an entity selection that its data needs to be refreshed from the server immediately, invalidating cached data.

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).
4D v17 R3 is now available!
To whet your appetite, here’s an overview of what this R-release has to offer:
- Create your own object methods and move one step closer towards classes in the 4D language.
- More 4D for iOS features for a customized mobile application with data formatters, personalized templates, and the ability to add your own icons.
- The ability to export the .4DB file into multiple text files as a first step towards full source control support – coming in a future release.
- 4D Write Pro is getting more feature-rich with new commands and attributes to create complex and beautiful documents.
- Import and export Microsoft Excel documents (.xlsx format) with 4D View Pro.
All of this and more awaits you!
Do you need to access your 4D data from a web page but don’t have a designer in your team? Are you uncomfortable designing the pages yourself because deep down you believe that it’s full of complicated and unwritten rules? Well, have you ever thought about Bootstrap?
In this blog post, we’ll look at how to take advantage of Bootstrap’s framework to design web pages in no time! We’ll also provide you with a database example to see how it can be combined with 4D transformation tags.
