Vba Error Handling Best Practices
Visual Studio 2013 Visual Studio 2012 Visual Studio 2010 Visual Studio 2008 Visual Studio 2005 Visual Studio .NET 2003 Enables an error-handling routine and specifies the location of the routine within a procedure; can also be used to disable an error-handling routine. 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. For more information, see Try...Catch...Finally Statement (Visual Basic).Note The Error keyword is also used in the Error Statement, which is supported for backward compatibility.Syntax Copy On Error { GoTo [ line | 0 | -1 ] | Resume Next } PartsTermDefinitionGoTo lineEnables the error-handling routine that starts at the line specified in the required line argument. The line argument is any line label or line number. If a run-time error occurs, control branches to the specified line, making the error handler active. The specified line must be in the same procedure as the On Error statement, or a compile-time error will occur.GoTo 0Disables enabled error handler in the current procedure and resets i

Join them; it only takes a minute: Sign up Confused about Error Handling in VB6 and the use of On Error GoTo up vote 3 https://msdn.microsoft.com/en-us/library/5hsw66as.aspx down vote favorite 1 I'm needing to troubleshoot some old VB6 code and I'm confused about the use of "On Error". In the sample below, if I surround the specific line of code I want to test with the On Error GoTo and the ErrHandler1, is that the ONLY line that's tested. Or will the divide by Zero be included if it's in the same Sub? On Error GoTo ErrHandler1 If http://stackoverflow.com/questions/9035664/confused-about-error-handling-in-vb6-and-the-use-of-on-error-goto Not Exists(BaseDirectory + "\ARCHIVE") Then _ MkDir BaseDirectory + "\ARCHIVE" ErrHandler1: Call MsgBox(Err.Number & vbCrLf & Err.Description, vbExclamation, App.Title) intValue1 = 12 intValue2 = 0 intValue3 = intValue1 / intValue Thanks. vb6 error-handling share|improve this question asked Jan 27 '12 at 15:25 JimDel 2,05453369 add a comment| 3 Answers 3 active oldest votes up vote 8 down vote accepted The divide by zero will be included and handled, and it will probably create a loop in your sample... The correct approach is like that On Error GoTo ErrHandler1 If Not Exists(BaseDirectory + "\ARCHIVE") Then _ MkDir BaseDirectory + "\ARCHIVE" On Error Goto 0 'this will un-hook you error handler intValue1 = 12 intValue2 = 0 intValue3 = intValue1 / intValue 'this will be an un-managed error Exit Sub 'this make sure that msgbox is shown only when the error happens ErrHandler1: Call MsgBox(Err.Number & vbCrLf & Err.Description, vbExclamation, App.Title) share|improve this answer answered Jan 27 '12 at 15:48 Max 4,23511426 Thanks for the explanation! –JimDel Jan 27 '12 at 16:47 +1. The documentation explains this pretty clearly... msdn.microsoft.com/en-us/library/aa266173(v=vs.60).aspx –MarkJ Jan 27 '12 at 16:53 3 Wrong - the division by zero is only handled if the MkDir operation does not thrown an error –Matt Wilko Jan
three flavors: compiler errors such as undeclared variables that prevent your code from compiling; user data entry error such as a http://www.cpearson.com/excel/errorhandling.htm user entering a negative value where only a positive number is http://www.aprenderaprogramar.com/index.php?option=com_content&id=421:errores-visual-basic-on-error-resume-next-goto-objeto-err-errnumber-y-errdescription-clear-cu00353a&Itemid=61 acceptable; and run time errors, that occur when VBA cannot correctly execute a program statement. We will concern ourselves here only with run time errors. Typical run time errors include attempting to access a non-existent worksheet or workbook, or attempting to divide by zero. The on error example code in this article will use the division by zero error (Error 11) when we want to deliberately raise an error. Your application should make as many checks as possible during initialization to ensure that run time errors do not occur later. In Excel, this includes ensuring that required workbooks and worksheets are present and that on error goto required names are defined. The more checking you do before the real work of your application begins, the more stable your application will be. It is far better to detect potential error situations when your application starts up before data is change than to wait until later to encounter an error situation. If you have no error handling code and a run time error occurs, VBA will display its standard run time error dialog box. While this may be acceptable, even desirable, in a development environment, it is not acceptable to the end user in a production environment. The goal of well designed error handling code is to anticipate potential errors, and correct them at run time or to terminate code execution in a controlled, graceful method. Your goal should be to prevent unhandled errors from arising. A note on terminology: Throughout this article, the term procedure should be taken to mean a Sub, Function, or Property procedure, and the term exit statement should be taken to mean Exit
