On Error Statement Enables or disables error-handling.Syntax Copy On Error Resume Next On Error GoTo 0 RemarksIf you don't use an On Error Resume Next statement anywhere in your code, any run-time error that occurs can cause an error message to be displayed and code execution stopped. However, the host running the code determines the exact behavior. The host can sometimes opt to handle such errors differently. In some cases, the script debugger may be invoked at the point of the error. In still other cases, there may be no apparent indication that any error occurred because the host does not need to notify the user. Again, this is purely a function of how the host handles any errors that occur.Within any particular procedure, an error is not necessarily fatal as long as error-handling is enabled somewhere along the call stack. If local err
a tutorial example on how to use 'On Error GoTo 0' to turn off the error handling flag
Vbscript Error Handling Best Practices
in a procedure to catch the first runtime error. As if err number 0 then you can see from the previous section, my last VBScript example reported the last runtime error, not on error resume next vbscript w3schools the first one. If you want to catch the first runtime error is a large section of code, you need to: Enter the "On Error Resume Next" https://msdn.microsoft.com/en-us/library/53f3k80h(v=vs.84).aspx statement in the main code to turn on the error handling flag for the main code. Put that section of code into a new subroutine procedure. Enter the "On Error Goto 0" statement in the new procedure to turn off the error handling flag for that procedure. Check the Err.Number property right after calling that http://www.herongyang.com/VBScript/Error-Handling-On-Error-GoTo.html procedure. Here is the modified VBScript example to catch the first runtime error in a section of code:

Be very cautious using it. –Nate Feb 4 '10 at 20:22 2 It makes more sense now. After some functions that can end on error resume up in error. They have a function called checkError after them. –Omar Feb 4 '10 at 20:37 add a comment| 6 Answers 6 active oldest votes up vote 56 down vote accepted It basically tells the program when you encounter an error just continue at the next line. share|improve this answer answered Feb 4 '10 at 20:19 David 2,2601523 add a comment| up vote 24 down vote It's worth noting that even when On Error Resume Next is in effect, the Err object is still populated when an error occurs, so you can still do C-style error handling.

Sometimes, the On Error follows the Goto label to alter the flow of execution, something like this in a Sub code block, now you know why and how the usag

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 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 so
