Automatic Refresh of OEM Build Licenses
4D automatically refreshes development licenses when they reach their expiration date. However, OEM build licenses (4D Server OEM and OEM XML keys) still need human intervention to be updated. This was causing issues on automated build chains and, in general, a loss of time.
4D 20 R9 extends the automatic refresh of licenses to OEM build licenses. This blog post will describe the different scenarios in which it will happen.
New class to handle incoming TCP connections
In 4D 20 R8, we introduced the TCPConnection class, allowing you to initiate TCP connections to remote servers. With 4D v20 R9, we’re excited to bring you the TCPListener class—your key to handling incoming TCP connections and building a TCP server directly in 4D.
With these two classes—TCPConnection and TCPListener—you now have full control over TCP communication, both client- and server-side.
Let’s walk through how to use them together.

Here we go with another set of tips and tricks.
The 4D Knowledge Base is a library of information about 4D technology where weekly tech tips and monthly tech notes are actively published. If you missed the last tips on the KB, that’s fine; here is a compilation from the past few weeks.
This blog post covers 15 tips:
Unlock the Power of AI with 4D AIKit: Automate, Create, and Innovate
We’re excited to introduce 4D AIKit, the first in a series of AI-powered features designed to bring intelligent capabilities directly into your 4D projects. As a built-in component, AIKit enables seamless integration of OpenAI’s state-of-the-art models into your development environment reinforcing our commitment to putting AI at the heart of innovation in 4D.
With just a few lines of code, you can enrich your applications with intelligent features like image generation, content moderation, advanced visual analysis, and conversational chatbots. This is just the beginning! The possibilities are wide open, enabling you to create smarter, more dynamic, and more responsive solutions than ever before.
Formulas in Label Wizard
Starting with 4D 20 R9, the Label Wizard component has received update to enhance your experience with formulas. This improves security by preventing the creation of malicious formulas. It also improves quality by avoiding the creation of incorrect formulas. Let’s dive into the improvements!
Enhancing macOS Privacy and Security with Application UUID
With the Sequoia update, macOS now relies on the UUID of applications for various privacy and security controls, such as network access. This new feature of macOS could cause issues on the end-user side, such as having to often re-authorize the built 4D applications. To address this, starting from 4D 20 R9, each 4D application built for macOS now has its own application UUID. This change ensures better-tuned access controls. Let’s delve into the details.
4D NetKit: Get Google and Microsoft 365 calendar events
Managing calendars and events is crucial for many applications, especially when integrating with popular services like Google Calendar and Microsoft 365. Starting with 4D 20 R9, you can easily retrieve and access calendars and events from these platforms with the new 4D NetKit commands. Whether you’re synchronizing schedules, building calendar-based features, or simply fetching event details, these commands enable seamless integration with Google and Microsoft 365 services.
Use class in embedded web area with $4d
With 4D 20 R9, 4D introduces new commands that allow developers to define an object context for $4d, ensuring only specific functions are exposed. Previously, using $4d meant exposing 4D methods to the web area, but now, you can define and use class functions instead. This improvement allows for better organization, encapsulation, and security when integrating 4D functionalities into web areas.
4D View Pro: Import callback ensures custom functions are fully resolved
Importing documents is a common task when working with 4D View Pro. However, when these documents contain custom functions, it can be challenging to determine when all calculations are completed before performing actions like printing or saving. To solve this, 4D 20 R9 makes sure that the callback formula of import commands is done only after all custom functions have been fully dealt with. This improvement gives more control and reliability when working with imported 4D View Pro documents.
