Errors happen, even in the absence of programmer error. You need to protect your programs and your data from the adverse effects of errors by practicing error handling.
Error handling (also known as
error trapping ) is the process of intercepting Jet's or Visual Basic for Applications' (VBA's) response to an error. It enables the developer to determine the severity of an error, and to take the appropriate action in response. This chapter shows you the techniques required to successfully implement error handling within your applications.
