Building services with 4D Mobile, Alex Heilmann, Edinburgh Bicycle Cooperative

Rightly enough, Wakanda is usually marketed as an “app factory”, bundled as a full stack framework in order to develop web applications.  But if you single out the Wakanda server from that bundle and look at its extensive API, you can start seeing Wakanda as a “services factory”.

New 4D Write Pro features that end users will love and give developers a new level of programatic document editing.
Roland Lannuzel

4D applications that work heavily with documents often rely on templates to generate invoices, reports, orders and more. Templates can be tricky to produce. Building them requires an advanced end user or developer.  With 4D v16 plus 4D Write Pro, your applications and 4D code gain access to the new concept of bookmarks.

Goodnight MosesWalker

Posted on December 5, 2016 by 4DMethod

Redirect your bookmarks!  After years of operating under the GitHub account named MosesWalker, I decided to rename it to 4DMethod to avoid confusion and make it easier to find.   All previous example code and demos are still available at https://github.com/4dmethod.

Cloud based storage with 4D and S3 – Bruno Legay

With Amazon’s Simple Storage Service (S3), it is possible to give your 4D application a taste of the cloud!  S3 can be used to store files, images, blobs, objects, and whatever else makes sense for your application.  S3 is cheap, resilient and flexible and can be accessed via a REST API.  In the demo, we will look at a component which makes it easy to integrate S3 in your 4D environment.  The component is free and provided with source.

Special Topic:
Messaging with 4D v16 –Thomas Maul.

Let’s chat about messaging and how to communicate. No, this isn’t about Snapchat, WhatsApp, emoji or digital stickers. This is about building your application with a modern multithreaded architecture using commands that reduce the problem down to a straightforward approach. Out is the concept of polling your variables for a change of status. Messaging uses a push architecture delivering state changes to your modularly built application.  4D VP of Product Strategy, Thomas Maul, will demonstrate how message passing commands are an approachable way for your application code to use the full processing power available to it.  Learn the details of Call Form and Call Worker, the new commands introduced with 4D v15 R5.  These key features will be available to everyone with the launch of 4D v16 and will revolutionize how you choose to write 4D applications.
