Create, Update, and Delete with Data Explorer

The Data Explorer is a powerful tool for visualizing data. Its capabilities allow administrators to effortlessly ensure data consistency. At the same time, developers can validate their code for creating, updating, or deleting data – all without the need to craft new forms.

Now, with 4D 20 R4, users have the ability not only to visualize but also to correct their data directly within the interface of the Data Explorer. That’s right! You can add, modify, or delete data directly in the Data Explorer interface.

A class for easy handling of your sub-forms

On the forum, several requests, tips, or questions have been asked about displaying a message, an hourglass, or some interface elements in the foreground of a form while blurring out the rest. You can create this type of interface with sub-forms and call forms. The code can get complicated if you’re working with a multi-page form.

To simplify your work, Vincent De Lachaux has prepared a class to simplify the management of sub-forms displayed in a multi-page form. It handles loading the sub-form on the fly, controlling it from a worker, and repositioning it if the main form is resized. You can focus on your dialogues without worrying about the mechanics.

Tailored Customization for Dates and Times

The manipulation of dates and times often requires specific formatting for various representations based on 4D’s internal resources or operating system settings.

While the default formats are usually all you need, there are scenarios in which custom formatting is essential, particularly for different geographical locations or unique requirements. In 4D v20 R4, significant advances have been made to meet this precise need

A New Way to Handle Errors

We’ve recently introduced a new error-handling mechanism using the new throw() command.
This marked the first step towards a new error handling system, positioned as close as possible to the code generating them.
In the next phase with 4D v20 R4, we’re expanding this approach to intercept errors during expression execution.
Let’s delve into the details.

Auto-Generated SSL/TLS Certificates for Client-Server Communications

To simplify the security of client-server communications, from 4D v20 R4 onwards, 4D Server generates its own SSL/TLS certificates instead of relying on the default certificates provided by 4D.

This update brings a significant advantage for both testing and production environments. You’ll experience heightened security measures without the necessity of providing your own certificates. Let me explain to you what will change.
