Statement (Visual Basic) Visual Studio 2015 Other Versions 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 statemen
three flavors: compiler errors such as undeclared variables that prevent your code from compiling; user data entry error such as a user entering a negative value where only a positive number is acceptable; and run time errors, that on error goto 0 vba 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. on error goto errorhandler The 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 https://msdn.microsoft.com/en-us/library/5hsw66as.aspx run time errors do not occur later. In Excel, this includes ensuring that required workbooks and worksheets are present and that 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 http://www.cpearson.com/excel/errorhandling.htm 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 Sub, Exit Function, or Exit Property. The term end statement should be taken to mean End Sub , End Function, End Property, or just End. The On Error Statement The heart of error handling in VBA is the On Error statement. This statement instructs VBA what to do when an run time error is encountered. The On Error statement takes three forms. On Error Goto 0 On Error Resume Next On Error Goto

On Error Resume Next P: n/a bob.needler I know On Error Resume Next is generally https://bytes.com/topic/access/answers/464909-error-resume-next considered lazy. But can someone tell me why the resume next in Exit_Handler does not seem to work? It generates the typical unhandled runtime error message from Access. If I comment out the 1st On Error Resume Next and the x = 1 / 0 on the next line there is no difference, i.e. ther same unhandled error on the same line. I included these 2 lines of code to demonstrate that On Error Resume on error Next does work in some cases. Anyone know why its "not working" in Exit_Handler? Private Sub Command44_Click() Dim x% On Error Resume Next x = 1 / 0 On Error GoTo Error_Handler x = 1 / 0 Exit_Handler: On Error Resume Next x = 1 / 0 'runtime error here is not ignored (i.e. not "skipped") by the resume next On Error GoTo 0 Exit Sub Error_Handler: GoTo Exit_Handler End Sub Mar 6 '06 #1 Post on error goto Reply Share this Question 3 Replies P: n/a Matthew Wells The error handler can only handle one error at a time. So when you triggered the first error, there is still an active error when you triggered the error in Exit_handler. You must first "handle' the error in err_handler by using the "resume" statement. If you change "goto exit_handler" with "resume Next" you'll see it works.
