Submitted by rinvizle on Thursday, February 9, 2017 - 19:01.
In this tutorial, we will teach you on how to create a Login, Register and Update User Profile Using Action Script 3.0. This project is very known in mobile applications. This application creates a Login form and a registration form for every user, each user can access and update their profile. Every data that the user fill in it will automatically save to the database.

Sample Code
