Excel Vba On Error Resume
working inside For-Loop up vote 7 down vote favorite 1 I'm trying to cycle through a table in excel. The first three columns of this table 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 on error goto doesn't work second time 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 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

frequent questions I come across relates to the situation where an active and enabled error handler section handles the first error as expected but then fails to handle any subsequent errors. (An enabled error handler is one that is turned on by an On Error http://excelmatters.com/2015/03/17/on-error-wtf/ statement and an active error handler is an enabled handler that is in the process of handling an error.) Here's the explanation (it's a little long, but bear with me!): The On Error statement is the heart of VBA error-handling. https://msdn.microsoft.com/en-us/library/5hsw66as.aspx Without an On Error statement, any run-time error that occurs will display an error message, and code execution will stop. There are 4 distinct On Error options: On Error Resume Next On Error GoTo some_label/line_number On Error Goto 0 On on error Error Goto -1 On Error Resume Next This is the simplest error handling option but also the most dangerous and most often misused. It ensures that when a run-time error occurs, control simply goes to the statement immediately following the statement where the error occurred, and execution continues from that point. There is no message to alert the user as to the fact that an error has occurred, or to what it might be. A typical good use of this structure on error goto is when there is a predictable error that you want to override – often assigning an object that may or may not exist to a variable. For example, when testing for the existence of a worksheet in a workbook, you can loop through all the worksheets checking the name of each one, or you can employ an On Error Resume Next statement like this: Dim ws as Worksheet On Error Resume Next Set ws = activeworkbook.worksheets("some name") If not ws is nothing then ' do stuff End If The danger of this is if you do not remember to reset error handling (by either simply disabling it with On Error Goto 0 or enabling an error handler – see below) all further errors in your code will be suppressed, which can make problems very hard to locate and debug – you may not even notice them until your code is already in real use, which is never a good thing! I frequently see people simply put On Error Resume Next at the top of their procedures when they can't figure out why an error is occurring – THIS IS NOT A GOOD IDEA!! On Error GoTo some_label/line_number Enables the error-handling routine that starts at the specified line label or number. If a run-time error occurs, control passes to that specified line, making the error handler active. (The specified line must be in the same procedure as the On Error s
