Go the distance with the best of 4D
Things have been really exciting for us here at 4D, but also in our community. Especially with 4Dv17 and its R-releases containing many groundbreaking features such as ORDA, 4D for iOS, 4D Write Pro, 4D View Pro, dynamic forms, and much more. Now there’s even more good news … we’re hitting the road to share all of these great advances with you in person! We’re hosting events where you can meet the 4D team face to face and gain in-depth knowledge about 4D technologies: 50+ countries and 44 cities around to introduce you to the latest 4D innovations!
4D Write Pro now supports virtual structures!
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!
Name your ranges and formulas in 4D View Pro
4D v17 R4 is on the way with a cool new 4D View Pro feature: named ranges and formulas. If you need to use formulas with references to cell(s) or constant(s), this feature can be a great help!
With these new commands, your formulas are more readable and easily accessible with 4D View Pro’s automatic completion.
Restricted queries with 4D for iOS
With 4D v17 R4, embedding and displaying filtered content in your 4D for iOS app is a piece of cake! With this R-release, you’ll be able to filter the data to be displayed in your mobile app.
Get coordinates in a 4D Write Pro document
By now, you should be familiar with the WP Get position command. At the very least you’ve read about it in this blog post. Introduced with v17, it helps you get information about the location of elements within your 4D Write Pro documents.
4D v17 R4 spices things up … now, it also returns coordinates!
Easily synchronize your processes
Preemptive processes are very useful for performing extensive calculations in parallel, using all of the cores in your CPU, but sometimes you need to delegate tasks to a cooperative process (e.g., using a non-preemptive command). With the New signal command, you can pause a process and wait for the response from another process!
New server administration commands
4D continues to deliver features to help you create your own applications to monitor your servers. From programmatically retrieving information about sessions, processes, and the application server, to getting information about the web server.
Having already provided you commands to read about statuses, 4D v17 R4 now gives you the ability to change statuses. You can now create your own administration interfaces as dialogs on the server, client, or even as HTML pages for web access. It’s up to you. These commands allow you to perform the same actions as the standard 4D administration interface. For example, you can send a message to your users to notify them of scheduled maintenance, or block new connections to the application server while you perform an operation on it.
Create a custom data formatter in 4D for iOS
With 4D v17 R3, we introduced basic data formatters for dates, percentage, time, etc. 4D v17 R4 takes things a step further by providing you the ability to create your own data formatters and use them directly from the Project Editor.
