Catalina (macOS 10.15) is now available and Apple has announced that the notarization of software distributed outside of the App Store has become a requirement. This may raise a few questions: what if my 4D application isn’t notarized? Will I be able to notarize it? How? Don’t panic! We’ve got you covered and this blog post provides the answers.
Less than a month to go before one of 4D’s most sensational releases goes beta! 4D v18, a major product release bursting with upgrades, enhancements, and exciting new features to make your coding a breeze.
A few weeks ago, we introduced action parameters so you could better interact with your 4D for iOS apps. They let you add, edit and delete records from your iOS device using edition forms. Well things are becoming even more interesting in 4D v17 R6, because now you can add pictures!
There have been requests to modify the 4D Server administration dialog, with some customers wanting to remove information and others wanting to add customized information. This AdminWindow component shows you how to do just that. You can use it “as is” or modify it to fit your needs.
Have you ever executed an action, nothing seemed to happen, and you didn’t know if you should click again or continue waiting? There’s no feedback provided, even if the application is performing an action in the background? Perhaps the action requires some time to return a result? As you may know, 4D already provides a built-in progress bar component that makes execution time more tolerable, but if you want something with a more web like design then keep reading, because that’s what the AJUI_Progressbar gives you!
iOS 13, first launched at the Apple’s annual Worldwide Developers Conference (WWDC 2019), to be released today, September 19. And we couldn’t be more thrilled to announce that some of the features Apple has unveiled for their latest iOS, will be available in 4D for iOS with the release of the v18! Here’s everything you need to know about the advances we have in store for you:
Want to recreate the 4D Server Administration Window with a web interface? Want to conveniently check what’s happening in the 4D Server without needing to go to the server room, to use a remote desktop, or to consume a 4D Client license? It’s now possible to view all of 4D Server’s main parameters(e.g., memory usage, drive space, users, processes, and even the real-time monitor) via the web.
In this blog post, we’ll walk you through a set of commands that 4D delivered over various R-releases to build your own web-based server administration dialog. Additionally, the regional technical manager of 4D Hispano (Angelo Caroprese) has provided a complete component to be used right in your applications.
Blog post by guest author Cannon Smith, a 4D developer from southern Alberta, Canada:
The introduction of collections and entities has dramatically changed the landscape in 4D, giving developers new ways to map business rules to code. Just recently I refactored several thousand lines of code that were central to the business rules of our application, resulting in a significant speed improvement (5xs faster) which our users are very happy about. This refactoring was largely about moving from old code constructs to objects, collections, and ORDA.
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!
Ever need to analyze the traffic of your ORDA requests between a client and the 4D server? Sometimes it may take a while to receive a response from the server, which can make you wonder if it’s due to network traffic or to an unoptimized request you’ve written! Thankfully, 4D v17 R6 makes it possible to determine the likely reason(s) for this latency with the new ORDA methods available on the ds object. They’re not only debugging functions, they also allow you to optimize your ORDA code with a better understanding of the sent requests.
