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.

Error Handling In Vbscript Tutorial
only takes a minute: Sign up VBScript — Using error handling up vote 58 down vote favorite 13 I want to use VBScript to catch errors and log them (ie on error "log something") then resume the next line of https://msdn.microsoft.com/en-us/library/53f3k80h(v=vs.84).aspx the script. 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?

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 102 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 14:36 answered Oct 1 '08 at 14:11 Dylan Beattie 33.3k2095154 9 :( ...

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!"
