A https://msdn.microsoft.com/en-us/library/5hsw66as.aspx good article is the one of CPearson.com However I'm still wondering if 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 http://stackoverflow.com/questions/6028288/properly-handling-errors-in-vba-excel method worked quite well so far. If I understood it right it should be like this: Block 2 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 ?

The first three columns of this table on error have text headings, the rest of them have dates as headings. I want to assign those dates, sequentially, to a Date-type variable, and then perform some operations based on the date To do this I am using a foreach loop on myTable.ListColumns. Since the first three columns do not have date headers, I have tried to set the loop up so that, if there is an error assigning the header string to the date-type variable, the loop goes straight to on error goto the next column This seems to work for the first column. However, when the second column's header is 'assigned' to the date-type variable, the macro encounters an error even though it is within an error-handling block Dim myCol As ListColumn For Each myCol In myTable.ListColumns On Error GoTo NextCol Dim myDate As Date myDate = CDate(myCol.Name) On Error GoTo 0 'MORE CODE HERE NextCol: On Error GoTo 0 Next myCol To reiterate, the error is thrown on the second round of the loop, at the statement myDate = CDate(myCol.Name) Can anyone explain why the On Error statement stops working? excel vba excel-vba for-loop error-handling share|improve this question asked Aug 17 '12 at 1:52 Swiftslide 41751828 Rather than using an error as your control structure, maybe an IF with an IsDate function would be more suitable in this scenario? –ray Aug 17 '12 at 2:29 1 If you are "blindly" handling the error - rather than taking specific action on an error type - then you should just use an On Error Resume Next outside your loop. At the moment you are using error handling afresh on each column. –brettdj Aug 17 '12 at 2:40 1 @brettdj, I don't think you can just resume next. The whole idea is to skip over the "more code here" code if the date conversion fails. So you need to go into a handler so that you c

I am refitting my code with error handling. However, there is a lot I don't understand. I especially need to know how to correctly use it in functions. I use Bovey's rethrow version of the error handler (at bottom). When I started, I was using the basic boolean (non-rethrow) method and turned my subroutines into boolean functions. (P.S. I am switching back to the boolean method based on the answer.) I need guidance on how to fit functions into this scheme. I want them to return their real values (a string or double, e.g., or -1 if they fail in some cases) so I can nest them in other functions and not just return an error handling boolean. This is what a typical subroutine call to bDrawCellBorders(myWS) would look like within an entry point. Sub calls seem to be working well. (I.e. it is a subroutine that was turned into a function only so it can return a boolean to the error handling scheme.) Sub UpdateMe() ' Entry Point Const sSOURCE As String = "UpdateMe()" On Error GoTo ErrorHandler Set myWS = ActiveCell.Worksheet Set myRange = ActiveCell myWS.Unprotect ' lots of code If Not bDrawCellBorders(myWS) Then ERR.Raise glHANDLED_ERROR ' Call subroutine ' lots of code ErrorExit: On Error Resume Next Application.EnableEvents = True myWS.Protect AllowFormattingColumns:=True Exit Sub ErrorHandler: If bCentralErrorHandler(msMODULE, sSOURCE,,True) Then ' Call a
