Vanessa Talbot joined 4D Program team in June, 2014. As a Product Owner, she is in charge of writing the user stories then translating it to functional specifications. Her role is also to make sure that the feature implementation delivered is meeting the customer need.

Since her arrival, she has worked to define key features in 4D. She has worked on most of preemptive multi-threading new features and also on a very complex subject: the new architecture for engined application. Vanessa has a degree from Telecom Saint-Etienne. She began her career at the Criminal Research Institute as a developer for the audiovisual department. She has also worked in media and medical fields as expert in technical support, production as well as documenting new features.

Product New constants for the command Get 4D files

Easy access to log files

Automatically translated from English

Log files can be extremely useful for troubleshooting. They’re also a big help for finding the root cause of an incident. Logs let us track of where a problem occurred, and when. Before, with the Get 4D folder command, you could easily access the folder containing all the logs. Now, 4D v16 R6 makes easy to find a particular log file, thanks to the enhancement of the Get 4D file command.

Product Create dynamic forms

Discover the power of dynamic forms

Automatically translated from English

You’ve told us how much you want a feature to dynamically build forms fully adapted to your end users’ needs. Well, we heard you, and 4D v16 R6 now opens new opportunities with dynamic forms! Provided as a preview in 4D v16 R6, dynamic forms allow you to programmatically build your forms in an object or load them from a text file. But this only scratches the surface of what we’ve cooked up for you…

Images in absolute position in 4D Write Pro

Automatically translated from English

Pictures speak louder than words, or so they say. In fact, according to researchers the brain processes images 60,000 times faster than words. 4D Write Pro is constantly evolving, version after version, to support more and more picture-related features. After in-line pictures and background pictures, 4D v16 R6 gives you the full control over picture insertion at a specific position in a document, in front of or behind text, as well as anchored to the page or specific parts of the document (i.e., header, footer, sections).

Tips

Play videos with 4D

Automatically translated from English

We’re in the visual and interactive content era. It’s becoming increasingly more and more prominent. Take a look at digital community statistics and you’ll discover that YouTube is the second most popular social network.

At some point, most web developers want to include videos in their sites and coincidentally, databases frequently contain links to videos (either hosted locally or on the web). This post shows you two ways to include videos in your 4D applications.

Product New icons for Form wizard

Fresh icons for Form Wizard

Automatically translated from English

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.

Product The 4D WEB Server information by programming

New command to get Web Server information

Automatically translated from English

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.

Product 4D v16 R5 supports the JSON pointers

Working with JSON Pointers

Automatically translated from English

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.

Product Generate disgest, a new 4D command

Generate digest now supports SHA-2

Automatically translated from English

The digest functions are mathematical functions that compute a digest key for a document. Identical documents have the same digest key; if you change part of the document, the digest key is different. These functions are very useful for checking data integrity when you exchange or compare data. In 4D v16 R5, 4D has enhanced the Generate digest command to support SHA-2 algorithms following security recommendations.

Product New 4D Commands to create a hash password

Hash and verify passwords for web user login

Automatically translated from English

Security is becoming an increasingly important topic as business applications become more frequently accessible through the web and are, as a result, more vulnerable to threats. As 4D is closely paying attention to security matters, in 4D v16 R5 we are providing you with a couple of security improvements, and one of them relates to the web users’ password protection through password hashing.

By the way, if you want to know more about how 4D is helping you to protect your data and with the security in general, I recommend you to take a look at this blog post

Product Set the minimal TLS version for 4D Web Server

More security for your 4D Server

Automatically translated from English

Over the years, security has become a core topic for business applications. Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both frequently referred to as “SSL”, are cryptographic protocols that provide communications security over a computer network. The TLS version that your application is using for web or client/server connections, for instance, contributes to its security level.

4D supports all TLS versions: 1.0, 1.1 and 1.2. The protocol version used is negotiated between the server and the client when establishing the connection. To increase the security level, beginning with 4D v16 R5,  the default minimum supported version is TLS 1.2, older versions are rejected, as they could be unsecure.
