VB Bob's Burgers Pt1 - Food Ordering in Visual Basic VB.Net

In this lesson we show how to build the first parts of a Food Ordering System for "Bob's Burgers". This lesson builds on the work we have done previously on Data Tables, Data Grid Views, Group Boxes, Radio Buttons, Custom Functions, and Input Validations including Regex. New learning in the Lesson is How to Setup and Use VB Checked Listboxes, How to setup and Read CSV Files, and How to Search a Data Table using the "Select" statement. This lesson will be useful to anyone building a VB.Net Application which requires Items to be selected and added to a Customer Order. This lesson builds on our previous Lessons on IO Streamreader, Custom Functions, Data Tables, and Data Grid Views. It is recommended, but not essential, that you have done our previous lessons about working with Data Tables, Data Grid Views, User Input Validation including Regex, Text 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 Ordering Systems, 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.
