Imagine a way of using your database with an object-oriented approach, without worrying about its physical structure. Imagine that you could maintain multiple current selections at the same time or that you could perform recursive queries in a single line of code. Well, this is now a reality thanks to ORDA! With 4D v17, your code can be written in an object-oriented mode, and you can easily navigate through your entire data model.
ORDA was one of the major announcements of 4D Summit 2018, opening a world of new possibilities in 4D. It’s now time to give you more details about the ORDA features available with 4D v17. To do so, we’ve prepared a series of blog posts dedicated specifically to ORDA core concepts and related features. And we’ll release them, one after another, day after day.
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.
Know what’s scary this Halloween?…Creating apps without 4D!
There are common user stories where there is a need to have a background image fill the entire printable area, such as paper-folding lines or a watermark. It’s also sometimes required by a company’s graphic charter.
Thanks to a newly added style for background images, it is now possible to create background pictures filling the full page in 4D Write Pro! You can control this attribute, by either the 4D language or standard actions, or even by using the 4D Write Pro widget.
Our own VP of Engineering, Laurent Esnault, explains exchanging information between multiple processes AND between processes and forms during his Break Out Session: Preemptive Multi-threading at 4D Summit 2016. Thanks to preemptive multi-threading, you can have more parallel processes, and thus add more and more users, for either desktop or web applications.

We are pleased to announce that 4D v16 R4 is the very first version where the whole 4D Windows 64-bit product line is no longer relying on the Mac2Win library from Altura! As announced in last April, in this strategy announcement post, we have done the work on 4D Server Windows 64-bit, which was the last step to reach.
Our Windows 64-bit product line can now fully take advantage of some modern technologies and make you benefit from it, such as support of Single Document Interface (SDI) windows for instance, also delivered with 4D v16 R4!
After the advanced list usage completely covered with 4D v16, 4D v16 R4 reaches a major step toward with 4D View Pro by providing our customers with the first step of our 4D View Pro spreadsheet solution, provided as a preview.
I am pleased to announce that the beta testing of 4D v16 R4 starts today! 4D v16 R4 is one of the feature-richest R-release ever delivered! There is so much to tell, I don’t know what to start with…
4D v16 R4 beta introduces 4 major product features, among others:
- A major 4D language enhancement with the object notation, making the developer’s life easier!
- Real tables in 4D Write Pro, answering the most-asked feature request for the old 4D Write.
- The Single Document Interface (SDI) mode making your Windows 64-bit application entering a new world where application windows are all independent!
- The first step of the 4D View Pro spreadsheet as a Preview, lifting the veil on a powerful spreadsheet solution for your 64-bit applications.
Upgrade now and benefit from the power of 4D v16 R3, available today for download!
Take advantage of our new features to optimize your programming productivity and easily design your custom 4D Write Pro interfaces in just a few clicks.
