4D Write Pro: Handle view properties by programming
4D Write Pro documents can be displayed in different modes (draft, page and embedded), each with their own viewing options. For example in Page view mode, you can choose to hide both the vertical and the horizontal rulers, but keep the headers and footers visible. The same goes for many other display properties such as zoom, spell check, page frames, etc. Thirteen different viewing options can be defined. The good news is that rather than handling all of these properties manually, it can now be done programmatically.
N to One relations with 4D for iOS
As of 4D v17 R5, 4D for iOS supports N to One relations so you can use descriptive relation names and simplify defining your project structure. You can visualize all of your table relations directly in the Structure section of the Project Editor.
New 4D commands to work with encrypted data
In a previous post, we discussed how to get started with data file encryption. Now we’re going to discuss an additional way to work with encrypted data files: New 4D commands. These commands are designed to support most encryption requirements and allow you to deliver an encrypted solution to your customers.
Concurrent merged clients from the same computer
You asked for a way to run multiple clients on the same computer AND simultaneously connect them to the same 4D Server. We not only heard you, we’re giving you even more with 4D v17 R5! Each connection now includes a separated cache folder containing the connection’s IP address, port, and a hash code. Thanks to this, you can now also connect several clients from the same machine to multiple servers on different machines. There’s no configuration necessary, just launch and watch it work!
Add values to your generic ORDA queries
By now you’ve surely noticed that ORDA queries are not only light and readable, they also make it easy to navigate through the entire data model using object-oriented concepts! In this blog post, we showed you how to write powerful and easy-to-maintain queries. One of the methods recommended was providing the query and values separately via placeholders. 4D v17 R5 takes placeholders a step further by allowing you to write generic ORDA queries: say hello to named placeholders for values!
Improved performance: up to 8xs faster (no, that’s not a typo)!
Scalability is one of our primary concerns and 4D v17 R5 brings good news in this area, particularly for those with a heavy process load on their 4D Server. You’ll notice significant improved performance speeds when remote clients (one, two, or even hundreds) are connected to your server.
4D’s internal architecture has been enhanced and now processor usage is fully optimizedopens in a new tab) in preemptive mode and simultaneous read/write accesses on the same table. As a result, you could see performance 4 to 8xs faster!
64-bit support brings new opportunities
Without sugarcoating it, 4D v17 R5 is 64-bit only! It’s no secret that many features, such as preemptive processes, new cache manager, 4D View Pro, and more are already only available in 64-bit. The bright side is that focusing on 64-bit systems makes it possible for us to incorporate more modern technologies and feature sets, as well as update many libraries. This change also brings new opportunities and in this blog post we’ll focus on the updated libraries and the positive impact on your 4D applications.
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!
Links in 4D Write Pro documents
As a developer or end user, you know how convenient hyperlinks can be. Without them, you would need to know the URL for every page on the internet! They let you turn your text or pictures into links to allow easy transitions from one place (e.g., a 4D Write Pro document) to another (typically a website).
What if links could offer more? What if they could launch the execution of 4D code or simply move the cursor to a different area in the same document? They can!
Pull to refresh with 4D for iOS
With v17 R5, 4D for iOS is shipped with a cool feature: Pull-to-refresh. It’s a very useful gesture, since all you need to do, to refresh your data, is scrolling to the top of the screen, then sliding your finger down. With this very intuitive feature, your app content is updated in a snap.
