Within the active error handler, you can determine the type of error that occurred and address it in the manner that you choose. When execution passes to an enabled error handler, that error handler becomes active. Instead it routes execution to an error handler, if one exists. When an error occurs in a procedure with an enabled error handler, Visual Basic doesn't display the normal error message. If there's no On Error statement, Visual Basic simply halts execution and displays an error message when an error occurs. The On Error statement directs execution in event of an error. The first step in routing execution to an error handler is to enable an error handler by including some form of the On Error statement within the procedure. When adding error handling to a procedure, you should consider how the procedure will route execution when an error occurs.

You can forestall many problems by including thorough error-handling routines in your code to handle any error that may occur. The user of your application is likely to be confused and frustrated when this happens. If you've implemented no error handling, then Visual Basic halts execution and displays an error message when an error occurs in your code. For example, an error occurs if your code attempts to divide a value by zero.

Second, your code may contain improper logic that prevents it from doing what you intended. For example, if your code attempts to open a table that the user has deleted, an error occurs. First, some condition at the time the application is running makes otherwise valid code fail. An error can occur in your application for one of two of reasons. When you are programming an application, you need to consider what happens when an error occurs. In this article Errors and error handling
