4D Web Access and Angular2 Components
Julio Carneiro from Pascal Information Technology Ltd will show his “RESTlike” 4D V16 Component that provides CRUD functionality via HTTP access to any 4D Database, along with an Angular2 Typescript Component.
4D Developer Edition 64-bit for OS X (and for Windows, available starting with 4D v16 R2) offers a powerful feature allowing you to execute 4D code in preemptive processes. Thanks to this new feature, your 4D compiled applications will be able to take full advantage of multi-core computers so that their execution will be faster and they can support more connected users.

Making Client/Server Workers Work: A real world example using CALL WORKER & CALL FORM
John Baughman from BY’te DESIGN in Hawaii will present a strategy where 4D forms can subscribe to a worker process to monitor when tables are modified. Each table’s trigger reports to the worker any time it fires. The worker in turn passes the trigger’s report on to all the subscribers monitoring the table. The approach works client/server or standalone and is written in 4D v16 R4 using dot notation.

Code Coverage Component, Dani Beaubien
Dani Beaubien from Open Road Development will demo his new Code Coverage 4D v16 Component that can be used by 4D developers to gain a deeper understanding of what code is actually executed while testing. The component is able to track the specific lines of code that are executed and provide a summary window providing various statistics as well as the ability to go into each method and view the lines that were executed, or more importantly those that were not.

Five years ago today, we had our first user group meeting under the name Midwest 4D and Wakanda User Group. It has been a really exciting transition to what we have now, a global user group where we have participation from all reaches of the globe! Thanks again to the last 26 presenters at 4DMethod meetings for putting in the extra effort to share your time, your experience, and especially your code with us.
I am looking forward to growing the group in coming years and continuing to deliver valuable discussion and insight into 4D and Wakanda development. I hope you’ll consider contributing to the group by doing a presentation yourself or becoming a 4DMethod Patron! Regardless, here’s to another great 5 years with you all in the 4DMethod user group 🙂
A basic strategy for monitoring worker activity or for creating a job queue using Call Worker and Call Form…

Special Topic:
A Publish/Subscribe Component for 4D, David Adams
David Adams demonstrates a component, with source, that implements a “publish/subscribe” messaging system on top of CALL FORM and CALL WORKER. There are a ton of uses for this sort of system, and it is also a very different way of thinking about structuring your code and objects. With the infrastructure in place, it’s very, very easy to extend and reuse interface elements, even complex ones, without a lot of code or new bugs. All of this works within one process with one window, one process with multiple windows, or even multiple processes. Continue reading
