Vbscript Error Message

like you, helping each other. Join them; it only takes a minute: Sign up Error in On Error statement up vote 2 down vote favorite I am totally not a VBScript developer. But as it usually happens I https://technet.microsoft.com/en-us/library/ee692852.aspx 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 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 http://stackoverflow.com/questions/6489941/error-in-on-error-statement 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. Sub Work On Error Resume Next 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() If Err.Number <> 0 Then ErrMyErrorHandler End Sub Sub ErrMyErrorHandler MsgBox Err.Description, vbExclamation + vbOKCancel, "Error: " & CStr(Err.Number) End Sub Work() But you should really underst

Syntax errors Syntax errors, also called parsing errors, occur at interpretation time for VBScript. For example, the following line causes a syntax error because it is missing a closing parenthesis: Runtime errors Runtime errors, also called exceptions, occur vbscript on error during execution, after interpretation. For example, the following line causes a runtime error because here syntax is correct but at runtime it is trying to call fnmultiply, which is a non-existing function: Logical errors Logic errors can be the most difficult type of errors to track down. These errors are not the result of a syntax or runtime error. Instead, they occur when you make a mistake in the logic that drives your script and you do not get the result you expected. You can not catch those errors, because it depends on your business requirement what type of logic you want to put in your program. For example, dividing a number by zero or a script that is written which enters into infinite loop. Err Object Assume if we have a runtime error, then the execution stops by displaying the error message. As a developer, if we want to capture the error, then Error Object is used. Example In the below example, Err.Number gives the error number and Err.Description gives error description.
