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 occur when VBA cannot correctly vba error numbers execute a program statement. We will concern ourselves here only with run time errors. Typical run on error vba time errors include attempting to access a non-existent worksheet or workbook, or 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 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 wait until later to encounter an error situation. If you have no error handling code and a run time error occurs, VBA will display vba on error msgbox 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

Err Object (Visual Basic) Visual Studio 2008 Other Versions Visual Studio 2005 Visual Studio .NET 2003 Contains information about run-time errors.RemarksThe properties of the Err object are set by the generator of an error—Visual Basic, an object, or the programmer.When a run-time error occurs, the properties of the Err object are filled with information that uniquely identifies the error and that you can use to handle the error or to learn more about it. To generate a run-time error in your code, use the Raise method.The properties of the Err object are reset to zero or zero-length strings ("") after an Exit Sub, Exit Function, Exit Property, or Resume Next statement in an error-handling routine. Using any form of the Resume statement outside of an error-handling routine will not reset the properties of the Err object. You can use the Clear method to explicitl

A good article is the one of CPearson.com However I'm still wondering if the way on error I used to do ErrorHandling was/is completely wrong: Block 1 On Error Goto ErrCatcher If UBound(.sortedDates) > 0 Then // Code Else ErrCatcher: // Code End If The if clause, because if it is true, it will be executed and if it fails the Goto will go into the Else-part, since the Ubound of an Array should never be zero or less, without an Error, this method worked quite well so far. If I understood it right it should be like this: Block 2 On Error Goto vba on error ErrCatcher If Ubound(.sortedDates) > 0 Then // Code End If Goto hereX ErrCatcher: //Code Resume / Resume Next / Resume hereX hereX: Or even like this: Block 3 On Error Goto ErrCatcher If Ubound(.sortedDates) > 0 Then // Code End If ErrCatcher: If Err.Number <> 0 then //Code End If The most common way I see is that one, that the Error "Catcher" is at the end of a sub and the Sub actually ends before with a "Exit Sub", but however isn't it a little confusing if the Sub is quite big if you jump vice versa to read through the code? Block 4 Source of the following Code: CPearson.com On Error Goto ErrHandler: N = 1 / 0 ' cause an error ' ' more code ' Exit Sub ErrHandler: ' error handling code' Resume Next End Sub Should it be like in Block 3 ? Thank you for reading my question Greetings skofgar excel vba share|improve this question edited Jun 28 '14 at 13:37 asked May 17 '11 at 8:38 skofgar 7042916 7 rather than risk throwing an error with If Ubound(.sortedDates)>0 use If IsArrayAllocated(.sortedDates) = TRUE –osknows May 17 '11 at 8:53 Wow! that was fast :-) - thank you, that makes the On Error Goto unnecessary here... –skofgar May 17 '11 at 8:56 But if it wasn't an array check.. though I can't of any other case.. I think my question is answered like this - there's no way to vote up your comment is there?, because it's
