Write your own methods for objects

Automatically translated from English

A new command is at your disposal allowing you to use formulas in your code. You can now encapsulate them in objects and call them when needed. There’s no more need to write your code as text. Now you can just pass your formula in your command and that’s it! This is a great addition, since your code isn’t text, you can benefit from Syntax highlighting and all the other advanced functionalities of the code editor!

Automatically translated from English

Developing an application is often a very collaborative job, involving many people. In this case, you may want store your development in a source control repository, or have a history of the work done during the day, or send your database to a colleague and see the changes when they’re done working on it.

All of the above scenarios are now possible! Beginning with v17 R3, you can export the .4DB file into multiple text files. This offers you many new possibilities.

Compatibility settings – Use period and comma as placeholders (Part 2)

Automatically translated from English

We’ve started a series of blog posts on compatibility settings and the secret options that can drastically help you improve the performance and the behavior of your applications. The first post was about QUERY BY FORMULA.

The second part of the compatibility series is about international usage of your business applications. This could mean selling to other countries – or having coworkers coming from other countries to work for a while, but using their local systems.

If you’ve ever seen or gotten reports like “the numbers are displayed as >>>>>>>>>”, this blog post is for you.

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!

Compatibility settings – or driving with the parking brake on(Part 1)

Automatically translated from English

In code kitchens, I usually spend some time with the database settings, especially with the Compatibility settings. Often certain settings don’t follow best practices and during discussions with the application developer, I hear “oh, I never changed these” or “I’m not sure about the impact, so better not touch them”.

Since they could drastically impact the performance or behavior of your applications, we’ve begun a series of blog posts to discuss some of these “secret” settings.

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.

Flash news about 4D Write Pro and anchored images

Automatically translated from English

Flash news: 4D Write Pro anchored images now support 4D Expressions!

Since 4D v16 R6, it’s been possible to add anchored images to 4D Write Pro documents. Once inserted, these images were static, either defined with a picture variable (or field), or by a picture path. Today, you have more flexibility: a valid 4D expression can also be associated to an anchored picture!
