Error-handling options are set in the development environment with the Options
dialog box. From the Visual Basic menu, choose Tools and then Options. The Options
dialog box appears. The errorhandling options are on the General tab, as shown
in Figure 11.1.
FIGURE 11.1 The error-handling options available
The first option for error handling in the development environment is to Break
on All Errors. If this option is selected and a runtime error occurs in your application,
the program will stop immediately. Execution will stop regardless of any error-handling
procedures you have in your code (discussed later in "Handling
Errors in Code"). The program stops regardless of whether the code that caused
the error is in a class module that is part of your Visual Basic environment.
Remember that these options are in effect only when you are running your code
in the Visual Basic development environment, not for Executables. Breaking on
All Errors is usually used when you have very little error handling in your procedures
and you expect some runtime errors to occur. It enables you to find and correct
the errors while you run your project interactively.
