A good article is the one of CPearson.com However I'm still wondering if https://msdn.microsoft.com/en-us/library/5hsw66as.aspx the way 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 http://stackoverflow.com/questions/6028288/properly-handling-errors-in-vba-excel On Error Goto 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 6842816 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

On error handling encountering a run-time error, an On Error statement enables or disables an error-handling routine within a procedure. A Resume statement can only be used in an error-handling routine - it resumes execution at a sepcified point after the error-handline routine finishes. You can get information on the error from the properties of the Error object - this object is the Err excel vba error Object. In this section, we cover: VBA Erros & Error Handling In vba programming you can have Syntax Errors or Run-time Errors. An error handler determines what action is to be taken within a procedure, on the occurrence of a run-time error. A syntax error occurs when you enter a line of code which is not allowed or recognized by Visual Basic. You will encounter a syntax error on misspelling a keyword or a named argument, for incorrect punctuation (ex. not specifying a comma as a placeholder for the omitted argument), use an undefined procedure, and so on. These errors are easier to locate as the Code Editor points them out at the time you are writing your code. A run-time error occurs at the time during which your code is running, that is after you have created your macro. There could be an error in your programming due to incorrect logic used in your code that prevents it from doing what you intended and may stop code execution, for example, if your

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, then the execution stops by displaying the error message. As a developer, if we want to capture the error, then Error Object is used. Example In the below example, Err.Number gives the error number and Err.Description gives error description. Err.Raise 6 ' Raise an overflow error. MsgBox "Error # " & CStr(Err.Number) & " " & Err.Description Err.Clear ' Clear the error. Error Handling VBA Enables an error-handling routine and 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 abruptly. On Error { GoTo [ line | 0 | -1 ]
