Access form object values by programming
An increasing number of developers are using the Form command to link their form objects and many of you require easy programming access to the values of those objects. So, to help you access the value of a form object, regardless of its variable or expression, we’ve added two new commands: OBJECT Get value and OBJECT SET VALUE.
Let’s see how to use them!
4D for iOS: Email authentication
Monitoring access to your mobile app is a very important capability that deserves further consideration. Email validation is one of the simplest and most secure ways to determine the authenticity and legitimacy of the person trying to log into your app. 4D for iOS enables you to easily handle this validation process by verifying that an email comes from whom it claims to be sent from, and by allowing you to block harmful uses of the email.
4D View Pro: Offscreen Areas
Want to dynamically generate 4D View Pro documents on a server and, for example, send them by email or calculate values? 4D v18 R4 introduces a new command to manipulate 4D View Pro commands in an offscreen area: VP Run offscreen area.
ORDA Classes to handle your data model
In a previous blog post, we introduced you to the world of ORDA data model classes. Now it’s time to get our hands dirty and learn more!
You already know that ORDA‘s structure (datastore, dataclass, entity, entity selection) is made up of objects. But they’re not just objects, they’re strongly-typed objects linked to specific ORDA classes. This means that you can write functions to hide the complexity of your data’s physical implementation.
Welcome to the world of ORDA classes
ORDA was a revolution with 4D v17. It opened a whole new world of possibilities and took you to another programming dimension. A dimension where you can easily develop applications using an object-oriented approach.
We didn’t stop there! We continued to add enhancements to ORDA through a set of features in each subsequent feature release. Now with 4D v18 R4, we’re thrilled to be going another step further with the availability of ORDA data model classes. Classes dedicated to your data model.
This will greatly elevate your code. Your applications can now easily expose services, be more manageable and easier to maintain, and seamlessly integrate with other applications.
This is another big feature made possible thanks to the projects!
Project by default. Binary on demand
Projects were introduced in 4D v17 R5. An architecture representing a giant evolution for 4D applications, projects opened the 4D world to source control tools, collaborative programming, code sharing, modularity, and much more! To make things even better (and simpler), 4D v18 R4 creates new projects by default, while developers – if they choose to do so – can continue to create binary databases via a simple setting.
4D v18 R4 Beta Starts Today
4D is pleased to announce the launch of beta testing for 4D v18 R4.
4D v18 R4 is one of the best Feature Releases ever delivered! I’m so thrilled to share all of the advances we’ve added to the ever-growing list of 4D features.
Without further ado, let’s get a sneak peek at the 20+ new functionalities waiting for you:
- ORDA classes make their first appearance to enable business-oriented code so you can hide complexity, reduce errors, and speed up the development process.
- A CryptoKey class is available to protect the confidentiality of your data, as well as verify the integrity of messages and the authenticity of senders.
- The 4D developer toolkit is bursting with additional features including a new declaration syntax for intuitive autocompletion, easy access by code to the values of form objects, and the ease of developing and debugging server code in project applications … just to name a few.
- More exciting features are included with 4D for iOS for even more engaging apps, more UI possibilities, and more control over access to your app.
- You asked for it, you got it! 4D Write Pro can import and export different document formats via the widget, as well as direct export to PDF while supporting hyperlinks, image size optimization, and more.
- You no longer need a 4D View Pro license to use pro list box features. They’re now FREE!
- 4D View Pro also has a whole new set of commands to give you further control over your documents.
- To make things even better (and simpler), 4D v18 R4 creates new projects by default, while developers – if they choose to do so – can continue to create binary databases via a simple setting.
- And much more (see below).
