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 ErrMyErrorHandler Dim objExcelApp Dim wb Dim ws Set objExcelApp = CreateObject("Excel.Application") Set
Vbscript On Error Goto Sub
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? Thank you. vbscript share|improve this question asked Jun 27 '11 at 7:45 Grigory 45911024 add a comment| 3 Answers 3 active oldest votes up vote 3 down vote accepted looks like you can not point custom label to error handler in VB Script. 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. Using your example, you'd really be trying to do something like this.

This documentation is archived and is not being maintained. Handling Errors in VBScript There is little difference between the methods used in Visual Basic and those used with VBScript. The primary difference is that VBScript https://msdn.microsoft.com/en-us/library/ms675540(v=vs.85).aspx does not support the concept of error handling by continuing execution at a label. In other words, you cannot use On Error GoTo in VBScript. Instead, use On Error Resume Next and then check both Err.Number and the Count property of the Errors collection, as shown in the following example: Copy

Do you guys have like a template Error Handing Sub Routing, or Function.. someting that you use throughout your scripts to make them robust and to make the code more efficient?? If any of you guys do, please post something.. lead me in the right direction. Or even a good way to display the error.. Would be much appreciated.

For file and directory manipulations, always use FileExists or FolderExists methods of FSO to determine if they are always there. Comprehensive error handling does add complexity to the script itlself, but I think it's worth it, espcially for larger scripts. #3 Bushmen Total Posts : 122 Scores: 0 Reward points : 0 Joined: 2/4/2005Location: Status: offline Re: Runtime Error Handing in Vbscript Sunday, February 20, 2005 2:59 AM (permalink) 0 thanks guys. i've just noted, some people use On Error Resume Next.. or On Error Goto 0 or on Error GoTo "SubName" and i wasn't sure when to use what.. or if there is a better one to use.. i guess the question is too vague. Thanks
