Welcome to Visual Basic 202, brought to you by VBLearningZone.com. I am your instructor, Richard Rost.

In today's class, we are going to make a hot dog stand application. We are running a hot dog stand, and I want to be able to track how many hot dogs I am selling - hot dogs, French fries, and soft drinks. I want to calculate the quantity of each sold, the price of each, and then figure out the extended price, the sales tax, and the order total.

Then, I am going to learn how to append to text files, so I can create a history log of all my sales. At the end of the day, I can load that information into Excel or Access and calculate my daily sales totals.

We are going to see how to print a receipt and format it using Notepad. We will learn a lot more about variables, user-defined types, arrays, modules, Sub Main, public subroutines, constants, and many miscellaneous functions.

The prerequisite for this class is Visual Basic 201. Before taking this class, I recommend you take 101 through 107, and then 201.

There is, of course, a web page for this class located at vblearningzone.com?geovb202. On this page, you will find sample project files, the course outline, and the student discussion forum. If you have any questions about the material covered in today's class, post them here on the discussion forum.

If you are watching this class in the Annecrane Video Player or online theater, you will see this page load up to the right of the videos. Join the discussion by posting your thoughts here in the student discussion forum.

In today's class, I will be using Microsoft Visual Basic 6.0. If you are using a different version of VB, such as VB.NET or VB205, you will find that the interface is different. However, most of the Visual Basic programming code will work just fine.

I strongly recommend you sit back, relax, and watch each video through once without doing anything. Then, replay the video again, and follow along with the examples, building each project as I do.

Do not try to apply what you are learning immediately to other projects that you might be working on. Instead, build the sample project in class with me.

Summary

Today's video from Visual Basic Learning Zone is Visual Basic 202. I'm Richard Rost, and I'll be guiding you through this session.

In this class, we'll build a hot dog stand application. Imagine you're running a hot dog stand and you need to track sales of hot dogs, French fries, and soft drinks. We will cover how to record the quantity sold for each item, calculate the individual prices, and then determine the extended price, sales tax, and the final order total.

We'll also explore how to append data to text files, which is useful for creating a history log of all your sales. At the end of your business day, you can then take this information and load it into Excel or Access to analyze your daily totals.

Printing a receipt and formatting it using Notepad will also be included in this class. This project serves as a practical way to learn more about key programming concepts in Visual Basic. We'll work with variables, user-defined types, arrays, and modules. I'll show you how to use Sub Main, public subroutines, constants, and other helpful functions.

To get the most out of this course, make sure you have already completed Visual Basic 201. It's also a good idea to take the earlier courses, 101 through 107, before starting 201 and this one.

There is a dedicated web page for this class at vblearningzone.com?geovb202. On the site, you can find sample project files, the course outline, and a student discussion forum. If any questions come up while working through the material, be sure to post them on the discussion forum.

If you are using the Annecrane Video Player or the online theater, the web page should appear next to the videos. This makes it easy to join in and interact with other students on the discussion forum.

During these lessons, I'll be working in Microsoft Visual Basic 6.0. If you happen to use a different version, such as VB.NET or VB205, you'll notice some differences in the interface, but nearly all the programming code and logic will still apply.

My suggestion is to watch each video completely one time through without doing any hands-on work right away. Then, watch it again and follow along, building the project step by step as I do. It's best not to try to adapt what you're learning immediately to other projects, but instead to focus on building the class project with me.

You can find a complete video tutorial with step-by-step instructions on everything discussed here on my website at the link below. Live long and prosper, my friends.
