Taking effect on May 25, the General Data Protection Regulation (GDPR) imposes new privacy restrictions governing the collection and use of personal data of European Union (EU) citizens.
And as a first step to help you get more insight into the GDPR law, we’re pleased to announce the first part of a GDPR dedicated guide: General Data Protection Regulation and 4D.
Like many other programming languages, 4D provides the ability to iterate over numbers with a For(…) / End for statement, or over a condition thanks to the While(…)/End while and Repeat/Until(…) keywords. These iterations (or loops) are very useful, but not the most appropriate way to iterate over advanced data types such as collections and entity selections. That’s why the new For each(…)/End for each iterator has been created, to help ease your coding!
4D v17 includes dynamic forms, initially introduced in 4D v16 R6, a powerful and flexible way to dynamically build forms fully adapted to your end users’ needs. The possibilities of dynamic forms are tremendous. In this post, we’ll see a concrete example of what you can do with these new forms.
4D Summit 2018 which took place in Paris and Washington DC recently, was filled with huge product announcements and a plethora of exciting sessions. It was a great experience for everyone who was able to attend! More than 450 attendees were on site to witness a lot of incredible revelations.
In this blog post, we’ll recap the highlights from this year’s 4D Summit.
In this latest addition to the ORDA series, we’ll look at how the new ORDA concepts can interact with existing objects and collections. In fact, it’s possible to turn entities and entity selections into objects and collections, as well as build entities and entity selections from objects and collections. By doing so, you can easily integrate ORDA code within your existing code. You can take full advantage of ORDA without needing to rewrite your code!
ORDA is a major innovation of 4D v17, this is why we’re dedicating an entire series of blog posts to ORDA. While ORDA has its own concepts that are very different from the classic approach, it’s still possible to mix ORDA with your existing code.
In a nutshell, this blog post will show you how you can update the current selection of a table from an entity selection and get an entity selection from the current selection of a table. It’ll allow you to smoothly integrate ORDA concepts into your existing 4D code, step by step.
Recently, 4D introduced of a new type of variable: collections, as well as a large set of methods to manipulate them. With 4D v17, the possibilities of collections is becoming larger by being able to easily display the content of a collection. How? List boxes of collection type!
After learning how you can create, update, and delete data, here is a new entry in the ORDA series. In this post, you will see how you can query your datastore in an object-oriented mode. With ORDA, queries are lighter, more readable, and you can navigate through the whole data model using object-oriented concepts !
On top of that, ORDA makes it possible to very easily query several related tables, manage recursive relations on the same table, and use several logical operators in a single query. Plus, you don’t have to worry about setting relations between tables … manually or automatically !
After introducing Perfect Forward Secrecy, the security level of 4D Web server has been increased again with the support of HTTP Strict transport Security (HSTS). Henceforth, 4D Web server is compliant with the very latest security protocols. Simply upgrade to 4D v17 and enable HSTS to get the A+ ranking (the highest level) from SSL Labs for your web sites!
Sometimes the information you include in your document is best displayed in columns. Not only can columns help improve readability, but some types of documents – newspaper articles, newsletters, flyers, etc. – are often written in column format. The good news is that with 4D v17, you can henceforth create multi-column documents with 4D Write Pro! And beyond document creation, you can also convert your existing 4D Write documents containing multiple columns.
As in the 4D Write plugin, it’s possible to define the number of columns for an entire document. But here’s a good example where 4D Write Pro exceeds 4D Write: you can also set a different number of columns … per section!
