In the first and second episodes of this trilogy, we demonstrated the basics of ORDA using list boxes, entities, and entity selections. We also showed the way to use similar list boxes with distinct data sources and how to use Meta info expression to improve the list boxes’ graphics.
Today we’re going to have even more fun, with less code!
In the first episode of this trilogy, we demonstrated the basics of ORDA using list boxes, entities, and entity selections. Today, we’re going a bit deeper by running some queries that will take advantage of recursive relationships. We’ll also have a quick look at how to display list boxes nicely using the “meta info expression” property.
We can all agree that ORDA is a great 4D V17 feature. A kind of revolution in the way of thinking and programming. 4D databases will never be seen the same way as before.
ORDA allows you to conceive advanced applications in less time, with more readable and clean code. To show you the power of ORDA we’ve prepared a series of tips for you, divided into three episodes. In this first episode, we’ll demonstrate how links should now be considered more as entities and entity collections, and we’ll show you how listboxes can now be based on entity selections, rather than selections or arrays.
We couldn’t be more thrilled to announce that the wait is over and 4D v17 is now available!
This groundbreaking release can open lots of options for your next 4D-based application. Though by no means exhaustive, here is a list of features to whet your appetite for this release:
Do you need to create a 4D View Pro document using code, without any user interface? It’s possible! Because 4D View Pro documents are objects, it’s very easy to create off-screen documents. You can create a new document in a variable of object type and manipulate it through its properties. When your document is ready, you can register it in your database, in a file, or display it directly in a 4D View Pro area.
ORDA was one of the major announcements of 4D Summit 2018, opening a world of new possibilities in 4D. To learn more about ORDA and its benefits, check out this post to see how ORDA will change the way you work.
As 4D v17 approaches, it’s worth taking a moment to pause and think of all the possibilities 4D Write Pro has to offer. For those who have extensive 4D Write programming skills and are wondering if 4D Write Pro can compare, this blog post will answer this question and more! We’ll even give you a database example of a complex travel brochure to show you what 4D Write Pro is capable of and how it’s surpassed 4D Write in many areas! And if you’re still hesitant about whether or not to take the plunge, watch this 4D Write Pro video from the 4D Summit 2018 featuring Caroline Briaud, where she presents the capabilities of 4D Write Pro and how far you can go to create complex documents.
Imagine you have a list of formulas containing table names and some fields … then days later you decide to rename your tables. Now your formulas are no longer valid, which is totally understandable!
Well, good news: the new Parse formula command allows your formulas to remain valid when renaming 4D language or structure elements.
Objects are at it again, continuing to demonstrate their utility to ease your life as a developer.
Using time (or duration) values inside of objects is now smoother and more intuitive. Beginning with 4D v17, times inside objects are set as seconds – and not milliseconds!
We are pleased to announce the release candidate for 4D v17.
If you haven’t already downloaded it, it’s not too late! Now’s the time to run your applications on 4D v17, and take advantage of the many features this release has to offer.
