attempting to divide by zero. 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 vba on error exit sub 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 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 on error goto vbscript 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 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

Error handling is important because in case of any unexpected exceptions your code doesn’t break. Even if any fatal unexpected error occurs in the code then also you should ensure that the code should terminate gracefully. http://www.cpearson.com/excel/errorhandling.htm Definition of VBA On Error Statement: On Error statement instructs VBA Compiler, what to do in case any runtime exception are thrown.

For example: Try line 1 line 2 line 3 line 4 ( here the exception is thrown and jumps to the catch) line 5 <-- i would like the program to continue its execution loging the error line 6 Catch ex as Exception log(ex.tostring) End Try Thanks. vb.net exception-handling share|improve this question edited Nov 13 '12 at 12:56 gabsferreira 1,45941848 asked Jul 29 '10 at 20:24 carlos 3832623 add a on error goto comment| 8 Answers 8 active oldest votes up vote 8 down vote accepted If you're doing something that you know how to recover from or that isn't vital, you're supposed to wrap just that line in the try/catch with a specific catch. e.g. Try line 1 line 2 line 3 Try line 4 ( here the exception is throw and jumps to the catch) Catch iox as IOException ' or whatever type is being thrown 'log it End Try line 5 <-- i would like the program to continue its execution after loggin the error line 6 Catch ex as Exception log(ex.tostring) End Try share|improve this answer edited Nov 13 '12 at 13:01 gabsferreira 1,45941848 answered Jul 29 '10 at 20:36 Nikki9696 4,3241618 add a comment| Did you find this question interesting?
