As a 4D developer, you’ve probably already created and used formulas. They can be created via two commands, Formula and Formula from string. The latter has just been enhanced in 4D V20 R3 to be used without limits from components!
With 4D v20 R3, a new feature has been introduced to enable better journal management. This feature concerns the “Use log file” option, which can now be overridden like other backup parameters.
In this blog post, we’ll explain why this is useful and show you how to use it.
In 4D Write Pro documents, formulas are crucial and contribute significantly to their functionality. Previously, these formulas could be represented as values, expressions, or symbols.
However, to further enhance the user experience and improve readability, an exciting new feature with 4D v20 R3 has been introduced: the ability to assign names to formulas. This latest enhancement allows users to quickly identify and comprehend the purpose of each formula within the document.
Customizing WebSocket client headers lets you inject specific information, preferences, or requirements into the WebSocket connection establishment process.
From 4D v20 R3, you can transmit security information, application-specific data, or other data relevant to the server connection through websocket client headers.
Here is everything you need to know!
Starting with 4D v20 R3, you can wave goodbye to the days of writing multiple lines of code for variable declarations and assignments. Now, you can streamline your code, eliminate redundancy, and easily boost efficiency.
Here is how!
As we continue to integrate the Gmail API into 4D Netkit, we’re bringing you a comprehensive set of commands to seamlessly manage your emails.
With 4D v20 R3, we’re introducing new commands that empower you to effortlessly retrieve the list of labels, get emails, and efficiently remove them.
Let’s learn more!
PHP has played a crucial role in web development, and it was introduced into 4D v12 to offer features not readily available in the native language, such as zip, hash, or LDAP functionality. Over time, 4D has incorporated many of these PHP features into its core functionality. As a result, we decided to remove the built-in PHP interpreter in 4D v20 R3 and begin the deprecation process for PHP commands in v21.
While we won’t entirely remove the PHP commands from 4D, we strongly encourage you to use the system workers to execute PHP code in the future.
This blog post will guide you through this transition process, demonstrating how to use an external interpreter through PHP Execute and explaining how to execute PHP code effectively with a system worker.
In this blog post, we’re thrilled to introduce a powerful method to revolutionize how you manage and track changes within your data store. We’ll unveil the concept of a “stamp”, a specialized marker designed to streamline your data modification monitoring and show you how to tailor these stamps to your unique requirements.
4D offers powerful features to work with object collections. For example, you can create a collection of cities with their associated countries and continents. Manipulating these collections with built-in functions like sort, order, and filter becomes a breeze.
4D v20 R3 introduces the new multiSort() function to simplify this process. With this function, you can now easily sort and synchronize multiple collections.
