4D for iOS: Email authentication

Automatically translated from English

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.

ORDA Classes to handle your data model

Automatically translated from English

In a previous blog post, we introduced you to the world of ODRA 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

Automatically translated from English

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

Automatically translated from English

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.

Download your emails in MIME format with POP3

Automatically translated from English

Do you need to store all business emails, for example, for legal or fiscal purposes? These documents must be stored as they are. That is, how they were received … in their original, unconverted formats. 4D v18 R3 answers this need by providing you with a new method allowing you to get emails in their original MIME format.

ORDA: an up-to-date datastore without restarting

Automatically translated from English

We’re thrilled to announce that 4D v18 R3 includes an enhancement that will have a huge impact on the developer’s experience. A feature many of you have requested, and 4D delivers!

When you work in 4D standalone mode during the development phase (writing and testing your code), you’re no longer required to restart your database in order to have an up-to-date datastore (ds) when the structure is updated!

Now you don’t need to restart the database each time you need a new attribute or a new table in your code! It’s all automatic!

When you call the ds command, you get an up-to-date datastore object. This means that several versions of this datastore object are handled at the same time … depending on when you updated your structure … without breaking running processes.

If you work in client / server mode, this works fine for code running on the 4D Server.

For remote clients, you simply need to restart the client requiring the structure’s update.

Use 4D Write Pro documents as input forms

Automatically translated from English

Do you want to avoid users accidentally modifying a particular 4D Write Pro document (fully or partially)? Are you interested in keeping some parts of a document untouched (e.g., giving users the ability to fill in fields in a non-disclosure agreement while ensuring that none of the information in the document is altered or changed in any way)? If you’re nodding your head, then keep reading! 4D v18 R3 lets you keep parts of your documents protected, or in other words: “non-editable“.
