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.

Happy 5th Birthday, 4DMethod!!!

Posted on September 18, 2017 by

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 🙂

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.

Special Topic:
4D ACME Client – A Lets Encrypt client in native 4D code, Tim Penner
It is becoming increasingly important to use encrypted channels for web communications (HTTPS).

It is advised to use a signed certificate from a credible certificate authority. But, then it can become an administrative task to keep the SSL certificate up to date, not to mention the additional cost.
