Review and Preview
We continue our look at the Visual Basic environment and learn some new controls and new BASIC statements. As you work through this class, remember the three steps for building a Visual Basic project: (1) place controls on form, (2) assign properties to controls, and (3) write event procedures. In this class, you will examine how to find and eliminate errors in your projects, learn about the label and text box controls, and about BASIC variables. You will build a project that helps you plan your savings.
Debugging a Visual Basic Project
No matter how well you plan your project and no matter how careful you are in implementing your ideas in the controls and event procedures, you will make mistakes. Errors, or what computer programmers call bugs, do creep into your project. You, as a programmer, need to have a strategy for finding and eliminating those bugs. The process of eliminating bugs in a project is called debugging. Unfortunately, there are not a lot of hard, fast rules for finding bugs in a program. Each programmer has his or her own way of attacking bugs. You will develop your ways. We can come up with some general strategies, though, and that’s what we’ll give you here.
