Own the source code for Lightning and see how the magic happens. Lightning is a 4D Component that you can install into a new or existing 4D v13 through 4D v16 database to create a Web 2.0 application. Facilities are provided for controlling user access, designing forms, validating data entry and much more. Lightning is designed for the beginner, intermediate and advanced 4D developer. With Lightning, you are only required to have basic experience in programming html to get your 4D application up and running on the web. You can continue to write your code in the 4D Method Editor “comfort zone”, and let Lightning do the rest, it’s that easy.
