When working on a form, it often happens, for a reason or another, that you insert new objects within a group of existing objects in your form. In that scenario, the resulting object entry order often becomes illogical, and would let the user enter information in an awkward manner. This is where you need to restore the entry order to a logic one, and it can be a tedious task…
Over the years, security has become a core topic for business applications. As a 4D developer, you are constantly facing customers who pay close attention to the level of security in the solutions they use for running their everyday businesses.
To help you answer your customers’ security-related questions, we are pleased to announce the release of the 4D Security Guide.
This reference document describes all the built-in tools and techniques involved in creating a secured environment for your business applications: from authentication and TLS encryption, to data access system and data protection. Now it’s time for you to check it out!
There is an old saying: “Old is gold” meaning that new ways are not as good as the old ones. But the new way to say is “Old is gold but new is platinum“. We are not referring to jewelry here but two of 4D commands: MODIFY SELECTION and DIALOG.
Check out our video showing how easy it is to create an elegant brochure with 4D Write Pro, including the painter’s bio (his life, references and so on), as well as a collection of his paintings accompanied by descriptions. Finally, you’ll learn how to easily add a different front and back cover to complete the brochure.
Of course, creating other kinds of brochures, i.e. for real estate agencies, pharmaceutical laboratories, travel agencies, etc… is just as simple. So take a look and start coding now!
Sometimes little things can have a big impact … and it turns out that these little things we call icons are kind of important when it comes to today’s interfaces. That’s why 4D v16 R5 comes with a fresh set of icons available with the Form Wizard. These simple, flat and modern icons adapt perfectly to the macOS and Windows platforms.
The Get process activity command, added with 4D v16 R4, makes it possible to retrieve a list of running processes and connected users. With 4D v16 R5 we’ve further enhanced the command to make parsing the results easier. In addition to that, a new systemID attribute has been added to uniquely identify any process, whatever its type: user, 4D or spare.
This feature is another way of providing you the ability to create your own server administration dialog. Following the ability to retrieve information for all processes (added in 4D v16 R4), we are now offering you a new command which returns, as a whole, all runtime information about 4D Web server.
With 4D v16 R5, retrieving web server information has never been easier, thanks to a single command: WEB Get server info.
This blog post explores a 4D Write Pro-related functionality which will help you with the creation of complex documents, programmatically. Documents that can be either printed or sent by email.
An expression can now be a Picture! Handling pictures in your 4D Write Pro documents is becoming easier, offering vast possibilities. From now on, any expression returning a picture can be inserted. The most obvious cases are fields and variables, but it goes also for 4D functions and, last but not least, your own methods!

In 4D v16 R4, we enriched object commands so you can validate JSON objects. 4D v16 R5 is going even further by introducing the support of JSON pointers. Great – but what is a JSON pointer and what can I do with it?
Just like you don’t store company details for each employee in a database record (using a link to the company record instead), it can be really useful to structure a JSON document with parts that can be reused in a number of places.
For instance, let’s take an example of a website order; the customer enters the shipping address and designates the billing address as the same. Instead of duplicating the address information, we can define the shipping address as a reference to the the billing address.
