Without an On Error statement, any run-time error that occurs is fatal: an error message is displayed, and execution stops.Whenever possible, we suggest you use structured exception handling in your code, rather than using unstructured exception handling and the On Error statement.

Published on Feb 24, 2014By Andrew Gouldhttp://www.wiseowl.co.uk - Almost every procedure you write in on error goto VBA has the potential to go wrong at some point! Writing error handling code allows your procedures to fail gracefully instead of dumping the user out into the run time error dialog box. This video teaches you all about the On Error statement including how to ignore errors, how to trigger a custom error handler and how to resume running your code after an error has occurred. Towards the end of the video you'll also encounter the Err object which allows you to interrogate the error that has occurred and even raise your own custom errors.Visit www.wiseowl.co.uk for more online training resources in Microsoft Excel, Microsoft Access, Microsoft PowerPoint, Microsoft Word, Microsoft Project, Microsoft Publisher, Microsoft Visio, SQL Server, Reporting Services, Analysis Services, Visual Studio, ASP.NET, VB.NET, C# and more!

You can and should do all you can to prevent them, but when they happen you have to handle them. Introduction Trapping Errors at Run-Time Building Error Handlers Raising Your Own Errors Summary Introduction The various functions, statements, properties and methods available in Visual Basic and the components used in Visual Basic expect to deal with certain types of data and behavior in your applications. For example, the CDate() function can convert a value to a Date variable. The function is remarkably flexible in the type of information it can accept, but it expects to receive data that it can use to derive a date. If you provide input that it can't convert, it raises error number 13 - "Type mismatch" - essentially saying "I can't handle this input data." In an application, this type of error may be a program logic error (you simply passed the wrong data) or it may be a data entry error on the part of the user (you asked for a date and the user typed a name). In the first case, you need to debug the program to fix the mistake. However, there is no way for you to anticipate the behavior of the end users of the application. If the user enters data you can't handle, you need to deal with the situation. Dealing with errors at run-time is a two step process: Trap the Error Before you can deal with an error, you need to know about it. You use VB's On Error statement to setup an error trap. Handle the Error Code in your error handler may correct an error, ignore it, inform the user of the problem, or deal with it in some other way. You can examine the properties of the Err object to determine the nature of the error. Once the error has been dealt with, you use the Resume statement to return control to the regular flow of the code in the application. In addition to dealing with run-time errors, you may at times want to generate them. This is often done in class modules built as components of ActiveX server DLLs or EXEs. It is considered good programming practice to separate the user interface from the program logic as much as possible, so if a server component cannot deal with an error, it should raise the error in its client application rather than simply
