SUMMARY

• Debugging is the process by which programmers identify, find, and correct software errors.

• Software bugs are generally grouped into one of three categories: syntax errors, runtime errors, and logic errors.

• The Visual Basic Environment includes many debugging features such as breakpoints, the Immediate window, the Locals window, and the Watch window.

• Breakpoints are used to pause program execution.

• The Immediate window can be used to ascertain variable and property values.

• Variable and property values can be altered in the Immediate window.

• Variable and property values within scope can be viewed and managed in the Locals window.

• Watch expressions can be created and managed in the Watch window.

• Input validation generally involves checking for numeric or nonnumeric data entered by the user.
