Visual Basic for Applications Reference Visual Studio 6.0 On Error Statement See Also Example Specifics 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. Syntax On Error GoTo line On Error Resume Next On Error GoTo 0 The On Error statement syntax can have any of the following forms: Statement Description On Error GoTo line Enables the error-handling routine that starts at 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 line, making the error handler active. The specified line must be in the same procedure as the On Error statement; otherwise, a compile-time error occurs. On Error Resume Next Specifies that when a

a negative value where only a positive number is acceptable; and run on error goto 0 vba time errors, that occur when VBA cannot correctly execute a program statement. We will concern ourselves here only on error resume next not working 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 example code in this article https://msdn.microsoft.com/en-us/library/aa266173(v=vs.60).aspx 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 required names are defined. The more checking you http://www.cpearson.com/excel/errorhandling.htm 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 Sub, Exit Function, or Exit Property. The term end statement should be taken to mean

On Error GoTo -1 clears the error handling and sets it to nothing which allows you to create another error trap. Example: On Error GoTo -1 After the first error is raised, it will GoTo ErrorFound which will then clear the routine's error handling and set a new one, which will GoTo AnotherErrorFound when an error is found. Sub OnErrorGotoMinusOneTest() On Error GoTo ErrorFound Err.Raise Number:=9999, Description:="Forced Error" Exit Sub ErrorFound: On Error GoTo -1 'Clear the current error handling On Error GoTo AnotherErrorFound 'Set a new one Err.Raise Number:=10000, Description:="Another Forced Error" AnotherErrorFound: 'Code here End Sub Example: On Error GoTo 0 After the first error is raised, you will receive the error as error handling has been disabled.

If it is used properly, "On Error Resume Next" is a valid method of dealing with errors - but it is a method that needs to be used appropriately for the situation. While using it means that you don't get any 'annoying' error messages that stop your program, it can easily cause much bigger problems than that, such as: If one error happens, then the code after that point is likely to have errors too (especially if the first error occurred while doing something like setting the value of a variable). The follow-up error(s) that occur may be simple and 'safe', such as getting the wrong result displayed on screen (but not knowing it is wrong)... or they could be much more serious, such as accidentally deleting an important file, because you had an error getting the name of the file that you wanted to delete. If you have made any coding mistakes (such as putting a text value into an Integer variable) then your code wont do what it is supposed to do, and you wont know why. Not only is the problem hidden from you, but so is the location of it. If you are running within VB, you would normally get the line highlighted
