ourselves here only with run time errors. Typical run 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 vba error handling 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 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.

I tried to write: If IsError(Cells(i, http://www.cpearson.com/excel/errorhandling.htm c) / curr) Then 'CODE BLOCK 1 else 'CODE BLOCK 2 end if But VBA tells me that I have division by zero error when it tries to run the if-statement. It throws me into debug. But this is just the type of thing I want to trigger CODE BLOCK 1! excel-vba share|improve this question asked Sep 1 '13 at 19:48 user1283776 1,85172755 1 Why do you not just check if curr is 0 ? –Alexandre P. Levasseur Sep http://stackoverflow.com/questions/18562252/if-iserror-in-vba 1 '13 at 19:54 But yes, VBA is notably bad at error handling. –Alexandre P. Levasseur Sep 1 '13 at 19:54 There can be other types of errors as well, like there being text in the numerator. The easiest would be to just check for any error. –user1283776 Sep 1 '13 at 19:55 1 I figured I would try LINE1: On Error GoTo ErrCurr LINE2: Cells(i, c) = Cells(i, c) / instanceCurrency LINE3: On Error GoTo 0. But strangely the division by zero error isn't sent to the error handler. It triggers the debug. Any idea why? –user1283776 Sep 1 '13 at 20:04 1 I found the reason. There were some earlier GoTo statements in the code (written by another guy) that caused problems. –user1283776 Sep 1 '13 at 20:20 | show 2 more comments 2 Answers 2 active oldest votes up vote 4 down vote accepted The usual way to handle this would be i = 0 On Error Resume Next n = 1 / i If Err.Number <> 0 Then 'Handle error - code block 1 Err.Clear On Error GoTo 0 Else On Error GoTo 0 ' No error - code block 2 End If share|improve this answer answered Sep 2 '13 at 6:37 chris neilsen 30.6k63967 add a comment| up vote 2 down vote You can call all worksheet functions using Application.WorksheetFunction.IsError(args) You could also try doi

Description The Microsoft Excel ISERROR function can be used to check for error values. The ISERROR function is a built-in function in Excel that is categorized as an Information Function. It can be used as a worksheet function (WS) in Excel. As a worksheet function, the vba if error ISERROR function can be entered as part of a formula in a cell of a worksheet. Syntax The syntax for the ISERROR function in Microsoft Excel is: ISERROR( value ) Parameters or Arguments value The value that you want to test. If value is an error value (#N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME? or #NULL), this function will return TRUE. Otherwise, it will return FALSE. Applies To Excel 2016, Excel 2013, Excel 2011 for Mac, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000 Type of Function Worksheet function (WS) VBA function (VBA) Example (as Worksheet Function) Let's look at some Excel ISERROR function examples and explore how to use the ISERROR function as a worksheet function in Microsoft Excel: Based on the Excel spreadsheet above, the following ISERROR examples would return: =ISERROR(A1) Result: TRUE =ISERROR(A2) Result: TRUE =ISERROR(A3) Result: TRUE =ISERROR(A4) Result: FALSE =ISERROR("www.techonthenet.com") Result: FALSE =ISERROR(3/0) Result: TRUE Example (as VBA Function) The ISERROR function can also be used in VBA code in Microsoft Excel.
