For example, On Error Resume Next 'Do Step 1 'Do Step 2 'Do Step 3 When an error occurs on step 1, I want it to log that error (or perform other custom functions with it) then resume at step 2. Is this possible? and how can I implement it? EDIT: Can I do something like this? On Error Resume myErrCatch 'Do http://stackoverflow.com/questions/157747/vbscript-using-error-handling step 1 'Do step 2 'Do step 3 myErrCatch: 'log error Resume Next vbscript error-handling share|improve this question edited Oct 1 '08 at 14:13 asked Oct 1 '08 at 14:04 apandit 2,50611831 1 Dylan's response is about as good as VB gets in the Error handling department. This is why I always used Javascript when I could get away with it. –wcm Oct 1 '08 at 14:23 add a comment| 2 Answers 2 active oldest votes up vote 103 down vote accepted VBScript has no notion of throwing or catching exceptions, but the runtime provides a global Err object that contains the reuslts of the last operation performed. You have to explicitly check whether the Err.Number property is non-zero after each operation. On Error Resume Next DoStep1 If Err.Number <> 0 Then WScript.Echo "Error in DoStep1: " & Err.Description Err.Clear End If DoStep2 If Err.Number <> 0 Then WScript.Echo "Error in DoStop2:" & Err.Description Err.Clear End If 'If you no longer want to continue following an error after that block's completed, 'call this. On Error Goto 0 The "On Error Goto [label]" syntax is supported by Visual Basic and Visual Basic for Applications (VBA), but VBScript doesn't support this language feature so you have to use On Error Resume Next as described above. share|improve this answer edited Oct 1 '08 at 14:

VbScript on error resume next in vbscript with example VBScript has no notion of throwing or catching exceptions, but the runtime provides a global Err object that contains the reuslts of the last operation performed. You have to explicitly check whether the Err.Number property is non-zero after each operation. Example On Error Resume Next DoStep1 If Err.Number <> 0 Then WScript.Echo "Error in DoStep1: " & Err.Description Err.Clear End If DoStep2 If Err.Number <> 0 Then WScript.Echo "Error in DoStop2:" & Err.Description Err.Clear End If Although Microsoft? Visual Basic? Scripting Edition (VBScript) provides the Err object, and that object exposes the same methods and properties available in the VBA Err object, writing error handlers using VBScript is not the same as in Visual Basic for Applications (VBA). The primary limitation is due to the limited functionality of the On Error statement in VBScript. In VBScript, you cannot branch to an error handler by using the familiar On Error GoTo ErrorHandler syntax. You can only enable error handling in VBScript by using the On Error Resume Next syntax. The following code excerpt shows the error-handler portion of a script. The script performs simple division and then immediately checks to see if an error occurred and responds accordingly: intResult = intNumerator/intDenominator ' Check for errors as a result of the division. If Err <> 0 Then Select Case Err.Number Case DIVIDE_BY_ZERO If Len(txtDenominator.Value) = 0 Then strErrorResultText = "Missing!" Else strErrorResultText = "'" & txtDenominator.Value & "'" End If strErrorMessage = "Error: " & Err.Number & _ vbCrLf & vbCrLf & "The value you entered in the " _ & "text box was: " & strErrorResultText txtDenominator.Focus Case Else strErrorMessage = "Error: " & Err.Number & _ vbCrLf & vbCrLf & "Unrecognized error!" End Select MsgBox strErrorMessage, CRITICAL_ERROR MSGBOX_OKONLY, _ "Error Type = " & Err.Description End If Tweet Related TopicsMost Viewed Delays, wait, sleep in VbScript with example getElementById in vbscript with ex
