On Error Resume Next Vbscript
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 have to write a small script to check something. It opens Excel, writes something to it and closes it. But that's not vbscript error handling best practices 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

Error Handling - on error goto Label? MCubitt (Programmer) (OP) 5 Nov 03 03:52 Within VBS, is it possible to provide my own error handling, such:..on error goto myerrorhandle..quitmyerrorhandle:if Err.Number=3 thenecho "Oh no, not good"elseecho "Not so bad, but not great."end ifquit RE: Error Handling - on error goto Label? tsuji (TechnicalUser) 5 Nov 03 04:55 Hello MCubitt,Vbs does not support On Error Goto Label directive. Instead, it is not difficult to implement the functionality. Something like this illustrate the idea.set fso=createobject("scripting.filesystemobject")on error resume nextset f=fso.opentextfile("nonexisting.txt")errcode=err.numbererr.clearselect case errcodecase 53call errorhandle_53'case etc...case elsemsgbox err.number & vbcrlf & err.description'do something / call some routine
a tutorial example on how to use 'On Error GoTo 0' to turn off the error handling flag in a procedure to catch the first runtime error. As you can see from the previous section, my last VBScript example reported the last runtime error, not 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" 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 procedure. Here is the modified VBScript example to catch the first runtime error in a section of code:
Run this modified example code in IE, you will get: There is no error at this time. Before statement: x = 1/0 A runtime error has occurred: Err.Number = 11 Err.Description = Division by zero Err.Source = Microsoft VBScript runtime error What heppened was: When the first runtime error occurred on statement, x = 1/0, in the CodeToBeMonitored() procedure, execution stopped for that procedure, because the error handling flag was turned off for that procedure. Execution control was transferred back to the main code with the runtime error. Back in the main code, the execution continued because the error handling flag was turned on for the main code. When CheckError() was called at the end, Err.Number is 11, indicating that the runtime error occurred was a "Division by zero" error. Now this example code
