proper exception handling routines to catch and tackle every possible error. Error handling is important because in case of any unexpected exceptions your code doesn’t break.

But as it usually happens I have to write a small script to check something. It opens Excel, writes something to it and closes it. But that's not the point. The point is that I cannot manage to write code for error handling. This script: Sub Work() On Error GoTo on error goto ErrMyErrorHandler Dim objExcelApp Dim wb Dim ws Set objExcelApp = CreateObject("Excel.Application") Set wb = objExcelApp.Workbooks.Add(True) Set ws = wb.Sheets(1) ws.Cells(1,1).Value = "Hello" ws.Cells(1,2).Value = "World" wb.SaveAs("c:\test.xls") objExcelApp.Quit() Exit Sub ErrMyErrorHandler: MsgBox Err.Description, vbExclamation + vbOKCancel, "Error: " & CStr(Err.Number) End Sub Work() gives this error: Line 2 is the line with the On Error statement. What am I doing wrong?

You can only use on error goto 0 '(raises exceptions) on error resume next '(ignores exceptions) if you use the second syntax, you can catch occruing exceptions via Err global variable: if Err.Number <> 0 then MsgBox "Exception occured: " & Err.Decscription share|improve this answer edited Jun 27 '11 at 8:43 answered Jun 27 '11 at 7:48 heximal 7,46822149 add a comment| up vote 3 down vote Heximal is correct that VBScript does not allow custom labels for error handlers.

October 22, 2015 AnalystCave Leave a comment Writing VBA code is hard, but properly debugging code is even harder. Sounds like non-sense? Well I dare say developers spend more time debugging code than writing it. Looking for errors is what developers do most of the time! A critical part of debugging is proper error handling (VBA error handling in our case). Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. — Brian W. Kernighan However, today I don't want to expand on debugging VBA. That I covered in this post. No - today let's learn how to properly handle errors The Mouse Trap Analogy What is error handling? Take this analogy: Say you have a mouse (an error) in the house which turns up every now and then in the least expected moment as slips from your hands (an uncaught exception if you prefer). Without knowing where the mouse is and when it (the exception/error) will appear (in which line of code) you would need to search entire house to catch it (run through the entire code in our case). Obviously a better approach is setting mouse traps in several critical places in the house (corridors etc.) and waiting for the mouse to fall into your trap. So what is our mouse trap when speaking about VBA error handling? The On Error do this statement! Using VBA On Error The VBA On Error statement - tells VBA what it should do from now on, within the vicinity of the current block of code (Function or Sub), when an error/exception is raised. It is like setting a mouse trap - with the difference that you can tell it to drop the mouse off the dumpste
