In this lesson we show how to transfer data values from items on Screen Forms, and from Program Variables across multiple Forms by using Full Name Referencing.
This lesson will be useful to anyone building a VB.Net Application which requires a "pop Up" Form of Summary Data or needs pop up Help Text to be displayed.
We then Revisit the previous lesson Doctor Appointments Schedule, and create Unpaid Bill Data Text which can be displayed in a Message Box.
We then take the Unpaid Bill Data and use it to format an Overdue Bill Notice to the Patient in a Pop Up Form.
We strongly recommend that you purchase and download the resources pack for this lesson, as the code is fairly long and needs to be structured correctly. Also included in the Resources Download is the Patient Contacts XML File.
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.

Watch the following YouTube Video Tutorial about Using Data Across Different Forms.
We recommend you use the RESOURCE MATERIALS available below
to follow along step by step with the Tutorial Video.
The YouTube Video is free to watch as many times as you want, and the Lesson Build Guide including all required Images and full program code listing(s) are available at a small cost which can be paid for and downloaded using PayPal.
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.
