QUIC network layer: Automatic update and sleep mode
Our development of the QUIC network layer continues, and with 4D 20 R4, we now have the sleep mode and the automatic update. Let’s take a closer look at these enhancements and see how they compare to the way they work with other network layers.
4D keeps your selections of records consistent regarding deletion of records
Deletion of data should be handled with care. To prevent issues, we can use transactions or rely on backups and logs.
Some improvements have been made in 4D 20 R4 to make your selections of records stable and consistent regarding potential deletion of records in this selection.
Keep reading to learn how your 4D code will be so safe out of the box.
Create a Client/Server Application with Build4D tool
Introducing the latest iteration of the Build4D component, now accessible on GitHub. In previous blog posts, we discussed the possibilities with a compiled project, a component, and a standalone application.
Now you can create a script for your Client/Server application from A to Z. And easily integrate it with continuous integration tools.
Let’s see how.
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.
