On Error 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.

and VBA On Error Statement is an easy way for handling unexpected exceptions in Excel Macros. A well vba error number written macro is one that includes proper exception handling routines to catch and tackle every possible error. Error handling is important because in case of any unexpected exceptions your code doesn’t https://msdn.microsoft.com/en-us/library/5hsw66as.aspx break. Even if any fatal unexpected error occurs in the code then also you should ensure that the code should terminate gracefully. Definition of VBA On Error Statement: On Error statement instructs VBA Compiler, what to do in case any runtime exception are thrown. Syntax of On Error Statement: Basically there are three types of On Error statement: On Error Goto http://www.exceltrick.com/formulas_macros/vba-on-error-statement/ 0 On Error Resume Next On Error Goto

Which version do I have? More... You https://www.tutorialspoint.com/vba/vba_error_handling.htm can use the OnError macro action in Access to specify what should happen when an error occurs in a macro. Note: The OnError macro action isn't available in Access web apps. Setting The OnError macro action has the following arguments. Action argument Description Go to Specify the general behavior that should occur when an error is encountered. Click the drop-down arrow and on error then click one of the following settings: Setting Description Next Access records the details of the error in the MacroError object but does not stop the macro. The macro continues with the next action. Macro Name Access stops the current macro and runs the macro that is named in the Macro Name argument. Fail Access stops the current macro and displays an error message. Macro Name If the Go to argument is set to Macro Name, type vba on error the name of the submacro to be used for error handling. The name you type must match a submacro name in the current macro; you can't enter the name of a different macro object. In the example below, the ErrorHandler sub macro is contained in the same macro object as the OnError macro action. This argument must be left blank if the Go to argument is set to Next or Fail. Note: The macro design window was changed in Access 2010. If you are using Access 2007, the name of the macro to be used for error handling must match a name in the Macro Name column of the current macro. Remarks The OnError macro action is usually placed at the beginning of a macro, but you can also place the action later in the macro. The rules established by the action will take effect whenever the action is run. If you set the Go to argument to Fail, Access behaves the same way it would if there were no OnError action in the macro. That is, if an error is encountered, Access stops the macro and displays a standard error message. The main use for the Fail setting is to turn off any error handling that you established earlier in a macro. Example The following macro demonstrates the use of the OnError macro action. In this example,

Syntax errors Syntax errors, also called parsing errors, occur at interpretation time for VBScript. For example, the following line causes a syntax error because it is missing a closing parenthesis: Function ErrorHanlding_Demo() dim x,y x = "Tutorialspoint" y = Ucase(x End Function Runtime errors Runtime errors, also called exceptions, occur during execution, after interpretation. For example, the following line causes a runtime error because here syntax is correct but at runtime it is trying to call fnmultiply, which is a non-existing function: Function ErrorHanlding_Demo1() Dim x,y x = 10 y = 20 z = fnadd(x,y) a = fnmultiply(x,y) End Function Function fnadd(x,y) fnadd = x+y End Function Logical errors Logic errors can be the most difficult type of errors to track down. These errors are not the result of a syntax or runtime error. Instead, they occur when you make a mistake in the logic that drives your script and you do not get the result you expected. You can not catch those errors, because it depends on your business requirement what type of logic you want to put in your program. For example, dividing a number by zero or a script that is written which enters into infinite loop. Err Object Assume if we have a runtime error, t
