VB How To Use Data Across Multiple Forms in Visual Basic VB.Net

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. We then Revisit the previous lesson Doctor Appointments Schedule, and create Unpaid Bill Email Text which can be displayed first in a Message Box, and then in a Pop Up Form. As part of enhancing the Doctor Appointments Schedule, we also review creating Unbound XML Files, Name Spaces, Node List Searches, and setting up and calling custom Fuctions. This lesson will be useful to anyone building a VB.Net Application which requires presentation of summary information in a "pop up" Form. In the Pop Up Summary Form, data can be accessed from other Forms, other Programs, and even from External Files. The "pop up" Form method could also be used for building Help Screens into a VB.Net Application. This lesson builds on our previous XML File Processing Functions Lessons. It is recommended, but not essential, that you have done our previous lessons about working with XML Files and creating Custom Functions. This is a long lesson, and so we recommend you use the YouTube "Tools Cog" on the payer bar to watch it at a speed of 1.5x or even 1.75x. If you are a Teacher watching this video 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 this video which goes through everything in full detail slowly step by step with repetition of examples. This is a detailed video, if you want to fast track learning about accessing data across Forms, then just Download and quickly read through the PDF of the Presentation using the Link given further down below. There is also a downloadable Word Document giving all of the Form Designs as well as the Full Program Code that goes behind each Form. Then for anything you do not fully understand in these two documents, simply use the Timeline Index below to go and watch the relevant section of Video explanation. If you have the time it will be extremely beneficial to watch the entire video to maximize learning outcomes.
