Special Topic:
Different ways to access and display 4D data – Christophe Flament – Ponga Consulting, Inc.

4D is constantly evolving adding new concepts and features.  As 4D developers, we have to keep up.  Here is an opportunity to learn some of those new concepts.

In this demo, Christophe Flament will demonstrate how to access 4D data via HTTP requests, displaying it using ORDA: collection / object.  He will also explain some of the code techniques we can now use with 4D v18 R6.

Using a project database (Library-Demo) adapted from a v17 demo, Christophe will explain how you can display data into a form with a listbox loading it via an HTTP request.  This concept is useful, for example, if you want to create a Volume Desktop application that will run independently with no local data/ getting it from the 4D Server via HTTP request calls instead.  The same concept is also applicable to PHP code loading the 4D data into a web interface or using the Postman application for testing.

The presentation will explain:

Some of the latest commands available with 4D v18 R6 will be demonstrated:

A 4D Project on Github with some code examples will be made available.
