A ready-to-use component for easy Mobile Session Management
In a previous blog post, we introduced the concept of Mobile Session Management. A concept that allows you to keep track of users after their initial user request. In this blog post, we’ll provide you with a component to help you easily manage your mobile users.
How to Beta Test iOS Apps Using TestFlight
TestFlight is a free solution provided by Apple which allows you to send a testable version of your app to specific beta users. This way you can manage feedback from beta testers and apply any modifications (if needed) before your app is released on the App Store. In this blog post, we’ll explore how to take advantage of TestFlight for a bug-free production app.
ORDA – Genealogy – Episode three
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)
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.
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.
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.
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!
Create a 4D View Pro document offscreen
Do you need to create a 4D View Pro document using code, without any user interface? It’s possible! Because 4D View Pro documents are objects, it’s very easy to create off-screen documents. You can create a new document in a variable of object type and manipulate it through its properties. When your document is ready, you can register it in your database, in a file, or display it directly in a 4D View Pro area.
