Errors and Error Handling When you are programming an application, you need to consider what happens when an error occurs. An error can occur in your application for one of two of reasons. First, some condition at the time the application is running makes otherwise valid code fail. For example, if your code attempts to open a table that the user has deleted, an error occurs. Second, your code may contain improper logic that prevents it from doing what you intended. For example, an error occurs if your code attempts to divide a value by zero. If you have not implemented error handling, Visual Basic halts execution and displays an error message when an error occurs in your code. The user of your application is likely to be confused and frustrated when this happens. You can forestall many problems by including thorough error-handling routines in your code to handle any error that may occur. When adding error handling to a procedure, you should consider how the procedure will route execut

This Microsoft Word Tips & Microsoft Word Help page a basic introduction to error handling and gives you some examples of error on error handling methods. A more detailed discussion of the material can be found in the VBA Help file under the topics "On Error Statement" and "Resume Statement." Why use error handling? VBA help puts it like this: "If you don't use and On Error Statement, any run-time error that occurs is fatal, that is, an error message is displayed and execution stops." What is a run-time error? A run-time vba on error error is an error that occurs when code is running. A run-time error results when a code statement attempts an invalid operation. There are lots of invalid operations. For a list of things that can cause a run-time error see: "Trappable Errors" in VBA Help. Using the following example macros you can produce some rather obvious run-time errors and then use On Error and Resume statements to illustrate some of the error handling methods. To use these examples, start with a new blank document and copy the example macros to the document VBA project. Or download the demonstration file using the link a the end of this page. See: Installing Macros for instructions on how to set up and use the macros provided in this Microsoft Word Help & Microsoft Word Tips page.
