Do you need to build a customized 4D connection dialog? Interested in connecting your client application to different servers? These are two scenarios that 4D v18 lets you to handle. This blog post is for you if you want to create a custom remote connection dialog and connect it to merged 4D servers. Keep reading!
4D Write Pro – Insertion and deletion of rows and columns
You already know that 4D Write Pro allows you to create tables and append rows to them. With 4D v18, we’ve got more thrilling news! We’re excited to announce that managing the insertion and deletion of rows and columns is not only possible, it’s also very easy. This can be done either by programming, thanks to four new commands, or by using the interface (via the widgets or the contextual menu). Keep reading for more details!
C_VARIANT to store different type of values
Sometimes you want to write code being able to work with different variable types, this is especially true for generic coding. Using pointers can make code more difficult to read and debug. Sometimes it’s not possible at all, for example when you want to assign a generic variable to a form object as the data source.
A new command is now at your disposal to let you to declare a variable that can store different types of values. Say hello to the new C_VARIANT command!
4D Write Pro and tables- Easily resize columns
4D v16 R4 made your dreams come true with the delivery of a huge feature: tables. Real tables where text automatically wraps to fit the column size and don’t “break” when your data changes! Since then, you’ve been able to create tables with as many rows and columns as desired. Plus, you can define the style of the table, each row, column, or cell, including the width of the columns. Most of these operations were achieved by programming, but what if we told you that with 4D Write Pro v18, the width of columns can be resized by end users?
4D Write Pro: Style sheets are here
For 4D Write Pro, 4D v18 brings good news: the arrival of style sheets! We’re thrilled to announce that you can now manage your own style sheets for paragraphs or characters.
Frightening season. Delightful release ?
What is your disguise costume for this Halloween? Are you a witch? Have you turned yourself into a vampire? A hungry zombie looking for brains? Or perhaps Dr. Jekyll and Mr. Hyde is your thing?
Deployment made easy with 4D v18
4D v18 introduces a new architecture for files and folders to keep your deployed macOS package and Windows application folders intact. In a nutshell, the logs folder and all user-based settings, including 4D backup settings, are now stored next to the data file. In fact, the settings exist twice; one next to the structure to use as default settings for new data files, and one beside the data file, storing user changes.
As a result, the folder containing the structure can be read-only, since nothing is modified inside (*). Deployment becomes easier because the structure folder can simply be replaced, nothing within it needs to be copied beforehand.
(*) only in project databases. In binary databases the user & password tables are stored in the structure, so the folder must not be read-only.
Headless 4D applications
As a 4D developer, you may have already encountered a need to develop applications without a graphical user interface (GUI), otherwise known as a headless applications. Previously in 4D, this wasn’t entirely possible to do …. until 4D v18! In this blog post, we’ll go through some of the newly available capabilities so you can make your applications “headless”!
Why create headless applications? There are several use cases such as simulating Windows behavior on macOS, or having the Windows service behavior without using the service manager, and so on. But above all, it opens new opportunities such as developing bots with 4D.
4D v18 beta starts today
Beta testing for 4D v18, our most spectacular release yet, is starting today! And we couldn’t be more thrilled to share all the novelties we’ve prepared for you. More than +90 advances, including major enhancements to existing features, as well as new ones that were designed to ease your development journey and take your applications to new heights. And in case you want to have an overall idea on this release full potential, we’ve put together this extensive library of examples (HDIs).
Buckle up and let’s discover some of what 4D v18 Beta has to offer:
- Project database – Version control: a solution for collaborative programming. Enabling you to store your code in a source control system (e.g., Github, Perforce, etc.) in plain text files.
- Built-in encryption: protection at its finest with built-in data encryption on a per-table basis.
- 4D for iOS: a product fully integrated into 4D to extend your business applications to mobile with ease.
- ORDA: enhanced commands, enhanced performance … and then there is remote datastore.
- 4D language: extra 4D commands to enlarge your programming capabilities.
- 4D Write Pro: Style Sheets. Tables. Toolbar. Word Export. And much more.
- 4D View Pro: Ribbon Toolbar. Excel import/export. And the list goes on.
- And much more (see below).
4D v17 R6 is here
4D v17 R6, the latest R-release of one of 4D’s most groundbreaking major releases, is now available!
Here’s a sneak peek of what this R-release has to offer:
- Increased interactivity with your 4D for iOS apps thanks to the ability to create, edit and delete your app content using parameters.
- Advanced debugging capabilities at your disposal, such as the ability to retrieve the current execution call chain and a powerful new tool to analyze debug logs.
- Even more ORDA methods to build more sophisticated search criteria and optimize your coding.
- New functionalities have been added to the ever-growing list of 4D View Pro features: from customizing styles, to using collections to read and write values and formulas.
This list is far from exhaustive, see all the blog posts for 4D v17 R6!
