Banking app tutorial with 4D for iOS
ORDA – Genealogy – Episode two
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.
Find which Apple Developer Program you need
Your iOS app is complete and you’re ready to deploy? Now it’s time for you to choose the appropriate Apple Developer Program. Apple provides various programs for you to choose from: for App Store deployment, in-house deployment, or just for testing.
Don’t panic, we’ve got you covered! If you’re still wondering which Apple Developer Program best fits your needs, then keep reading.
Check out the Code Editor enhancements
The 4D Code Editor just got more user friendly! Say hello to character completion for quote marks “ ”, parentheses ( ), brackets [ ], and curly braces { }, as well as command blocks (For…End for, If … End if, etc.). But that’s not all, bracket matching has also been added to help you manage your collections, and the syntax for user methods is now displayed in the status bar just like a 4D command syntax!
New look for file and folder dialogs on Windows
The dialog boxes created by Select folder and the dialog box opened by 4D have now been updated with the latest version of Windows File Explorer. The overall user experience is improved, as you can now easily select your file or folder from different sources such as your computer, network or even your OneDrive account!
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.
4D Write Pro: A new bar is born!
We couldn’t be more thrilled to announce the birth of a new element in the 4D Write Pro Family: a new toolbar for 4D Write Pro!
Thanks to a design on point, the user experience is even better for creating documents.
Flash news about 4D Write Pro and anchored images
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!
Change the properties of several methods at once by code
We know that sometimes you want to change the properties of multiple methods without having to open the property dialog for each method.
For example, you want to set all methods to “Can be run in preemptive mode” status, then compile your database. So with compilation errors, you get an overview of the methods to modify to be preemptive.
Using the METHOD GET NAMES command to retrieve the list of methods from your database, and then using the METHOD SET ATTRIBUTES command to modify the attributes, lets you modify them all at the same time!
It’s time to fire up your first 4D for iOS project!
