In this lesson we show how to combine a VB User Login Screen with an external XML File of User Details so that we can authenticate User ID and Password.
Authenticated Users are then taken to the Main Menu Screen for our Application.
First we create an XML User Authentication File containing User IDs and Passwords.
The Final Application we build for this lesson consists of three interlinked Screen Forms.
We also show how to add Hide / Show Password Eye Icon Button functionality to the Login Screen Form.
The Step by Step Guide which is available below for this lesson, shows exactly what needs to be done.
This Guide has all of the Design Principles and Theory behind what is being done at each stage of application development.
Included in the Resources Download for this lesson are Visual Basic Code Listings, as well as Form Designs and Images.
If you are a Teacher or Instructor we suggest you click the downloads link below and get the lesson materials for your students.
Give these resources to your students and we think you will find that some of them will "get it" very quickly.
The other students need to watch the video for this lesson which goes through everything in full detail slowly step by step with repetition of examples.
Note that the example Lesson Images shown on this web page are basic Printscreens, whereas the actual original Images are of perfect clarity and quality in the downloadable PDF Guide for this lesson.

Before purchasing and downloading the following resources, check first with your Teacher or Instructor, as they may already have copies of these documents to give to you.
Our Programming Learning Modules are designed for complete beginners, and they have been extensively trialled with High School students learning Programming for the first time. They have a proven track record of being able to get everyone up and running with Microsoft Visual Basic - the world's most popular Beginner Programmer's language.
We highly recommend using the Step by Step Summary Guide as well as the other support materials to maximise learning outcomes.
Our students have found the Summary Guide to be far more useful than re-watching the Video, when it comes time for them to apply their newly acquired skills to Application Build tasks.

One known issue is that if you PayPal buy using Mircosoft Edge, it often displays prices with A's around them like: A$2.50A.
The Edge purchase will work okay, but it is probably best to do Pay Pal purchases using Google Chrome as your browser.
