How to connect Tableau with 4D

Automatically translated from English

In 4D Webinar – How to Connect Tableau with 4D, William Taylor (Technical Account Manager, 4D US) gave an overview of the Tableau tool and how it could be used to visualize your 4D data. In this blog post, we’ll dig into the technical details to give you a deeper understanding of how it works. This will allow you to build, for example, a visual showing the highest invoice total with nothing more than 4D REST and Tableau!


4D Webinar – 4D Write Pro: Create a Lightweight Email Composer

Automatically translated from English

Even during the lockdown, 4D continued to foster a sense of community through engaging content, interactive communications, and virtual gatherings such as webinars.

If you haven’t noticed, many of the 4D webinars presented by Will Taylor (Technical Account Manager, 4D US) have been made public on our Youtube channel

The most recent one is related to 4D Write Pro and how you can create a lightweight email composer:


Project by default. Binary on demand

Automatically translated from English

Projects were introduced in 4D v17 R5. An architecture representing a giant evolution for 4D applications, projects opened the 4D world to source control tools, collaborative programming, code sharing, modularity, and much more! To make things even better (and simpler), 4D v18 R4 creates new projects by default, while developers – if they choose to do so – can continue to create binary databases via a simple setting.


4D v18 R4 Beta Starts Today

Automatically translated from English

4D is pleased to announce the launch of beta testing for 4D v18 R4.

4D v18 R4 is one of the best Feature Releases ever delivered! I’m so thrilled to share all of the advances we’ve added to the ever-growing list of 4D features.

Without further ado, let’s get a sneak peek at the 20+ new functionalities waiting for you:


  • ORDA classes make their first appearance to enable business-oriented code so you can hide complexity, reduce errors, and speed up the development process.
  • A CryptoKey class is available to protect the confidentiality of your data, as well as verify the integrity of messages and the authenticity of senders. 
  • The 4D developer toolkit is bursting with additional features including a new declaration syntax for intuitive autocompletion, easy access by code to the values of form objects, and the ease of developing and debugging server code in project applications … just to name a few.
  • More exciting features are included with 4D for iOS for even more engaging apps, more UI possibilities, and more control over access to your app.
  • You asked for it, you got it! 4D Write Pro can import and export different document formats via the widget, as well as direct export to PDF while supporting hyperlinks, image size optimization, and more. 
  • You no longer need a 4D View Pro license to use pro list box features. They’re now FREE!
  • 4D View Pro also has a whole new set of commands to give you further control over your documents.
  • To make things even better (and simpler), 4D v18 R4 creates new projects by default, while developers – if they choose to do so – can continue to create binary databases via a simple setting.
  • And much more (see below).

4D v18 R3 is Here

Automatically translated from English

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 modularreusable, 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.

4D v18 R3 Beta starts today

Automatically translated from English

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 v18 R2 is here

Automatically translated from English

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.


A better understanding of 4D REST sessions

Automatically translated from English

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.


Test the powerful 4D REST server with Postman

Automatically translated from English

4D provides a powerful REST server that enables direct access to data stored in your 4D databases. This makes it possible, for example, to build an API to use with a modern front-end technology (e.g., Angular, React, etc.). In this blog post, we’ll provide the first introduction to the 4D robust REST server. You’ll see how to configure it and test the create, retrieve, update, and delete (CRUD) operations using the API testing tool, Postman.
