4D Write Pro now supports virtual structures!

Automatically translated from English

Understanding end user needs and creating user-friendly interfaces are high priorities for every application developers.

And as you may know, the 4D language lets you alias table and field names in order to make them more readable for end users. This allows easier translating and readability in standard dialogs (query, sort, and formula editors), but also filtering out any table or fields that should be kept away from end users sight. 

During 4D Summit 2018, we had requests to extend this feature to 4D Write Pro. Well, we listened and it’s now available with 4D v17 R4!

4D Write Pro – Say hello to Vertical ruler

Automatically translated from English

We’re pleased to announce that a new feature has been added to 4D Write Pro. In page mode, a vertical ruler can be displayed on the left side of the page! This lets you graphically manage the vertical margins. And if your document contains headers or footers, the spaces between them and the body of your document can be modified easily thanks to this ruler.

Improving databases tests

Automatically translated from English

As a developer, you’re aware that improving the quality of your developments is often based on unit tests. In order to launch these tests, developers and QA teams need tools to launch 4D databases in different modes (single user / client-server) and distinct environments (Macintosh / Windows).

4D products can already be launched using command line parameters to allow automatic testing or deployment. What if you want to create your own update mechanism or you need to handle a server farm with hundreds of 4D Servers running? Maybe you want to specify which database file to use – or pass parameters on launch …

Migrate 4D Write documents stored in picture fields

Automatically translated from English

4D Write Pro has become a mature product with a lot of functionalities, surpassing the 4D Write plug-in in many areas (tables and bookmarks, for example). Furthermore, 4D Write Pro is 64-bits compliant, which is great since most operating systems will soon be 64-bits only. Migrating your documents from 4D Write to 4D Write Pro is a “must do”. In order to help you and your customers’ migrations, we’ve simplified the migration process with a ready-to-use component!

ORDA – Genealogy – Episode three

Automatically translated from English

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!

Tips

ORDA – Genealogy – Episode two

Automatically translated from English

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.

ORDA – Genealogy – Episode one

Automatically translated from English

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.
