Power of objects and dot notation
With 4D v17 R5, we showed you how easy it is to manipulate an object to retrieve the attributes of a file or folder. Things have gotten even easier thanks to object notation! In this blog post, we’re providing you an HDI with a user interface to manage files and folders. This isn’t new in 4D since you could do it with classic 4D commands, but now you can do it easier and with fewer lines of code!
4D Write Pro: a new way to set TABS!
We’re thrilled to announce an exciting enhancement in 4D Write Pro! In addition to the features we’ve rolled out so far, 4D v17 R5 also includes a new feature for tabs.
Placeholders for attribute paths in ORDA queries
The ORDA features keep coming with 4D v17 R5! In a previous blog post, we showed you how to create generic queries with named placeholders for values. This post will focus on how to use placeholders for attribute paths (field names in tables).
Object notation to handle files and folders
4D already provides commands to handle files and folders, but what about new commands that take advantage of the power of object notation?
Objects have changed the way many 4D developers write code, making it more generic, flexible, easier, and faster. Now this wave of change is extended to files and folders. In this blog post, we’ll show you how easy it is to manipulate an object in order to retrieve the attributes of a file or folder (rather than calling several commands and storing the information in multiple variables). Things are getting a lot easier!
4D v17 R5 Beta starts today
We’re pleased to announce the launch of beta testing for 4D v17 R5.
4D v17 R5 is one of the most feature-rich R-releases ever delivered, and we couldn’t be happier to share all the advances we’ve added to the ever-growing list of 4D features:
- New built-in data encryption for your 4D databases is available, adding another level of security that is completely transparent, safe, and fast.
- Actions, incremental data synchronization, and N to one relations are now available for 4D for iOS.
- The SQL engine has been updated to allow reading 4D objects.
- More email features: Logging SMTP conversations, custom mail headers, and legacy charset support are ready and waiting for you.
- Additional advances in the 4D language and ORDA for better readability, efficient code maintenance, and optimized performance.
- In addition to commands being extended or renamed, you can also invoke a method from your 4D application, thanks to the power of 4D Write Pro.
- A powerful new ribbon-style toolbar to enhance the 4D View Pro user interface is at your disposal.
- And much more (see below).
2018 in Review: Our top 10 blog posts of the year!
It’s that time of the year where we take a look back at ten of our most-read posts. What a year it’s been! From ORDA to help you write code in an object-oriented mode, to 4D for iOS to extend your existing business applications to mobile devices, and much more. 2018 was filled with huge product announcements and a plethora of exciting features! Let’s take a look at the topics that grabbed your attention in 2018:
Compatibility settings – all the rest (Part 4)
We began a series of blog posts on compatibility settings and the secret options that can drastically help improve the performance and behavior of your applications (QUERY BY FORMULA, Transactions and period and comma). This final post of the series will give an overview of the remaining settings.
ORDA – Genealogy – Episode one
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.
Times inside objects… (and everywhere else)
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!
How to create a dynamic form from a table in 3 steps!
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.
