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

Language Elements by Category B. VBScript Constants C. Operators Index Colophon Error Handling Error handling does not involve finding errors in your scripts. Instead, use error handling techniques to allow your program to continue executing even error trapping though a potentially fatal error has occurred. Ordinarily, all runtime errors that are generated by the VBScript engine are fatal, since execution of the current script is halted when the error occurs. Error handling allows you to inform the user of the problem and either halt execution of the program or, if it is prudent, continue executing the program.The On Error Resume Next StatementThere are two main elements to error handling in VBScript. The first is the On Error statement, which informs the error trapping vbs VBScript engine of your intention to handle errors yourself, rather than to allow the VBScript engine to display a typically uninformative error message and halt the program. This is done by inserting a statement like the following at the start of a procedure:On Error Resume NextThis tells the VBScript engine that, should an error occur, you want it to continue executing the program starting with the line of code which directly follows the line in which the error occurred. For example, in the simple WSH script:On Error Resume Next x = 10 y = 0 z = x / y Alert za “Cannot divide by Zero” error is generated on the fourth line of code because the value of y is 0. But because you’ve placed the On Error statement in line 1, program execution continues with line 5. The problem with this is that when an error is generated, the user is unaware of it; the only indication that an error has occurred is the blank Alert box (from line 5) that’s displayed for the user.TipA particular On Error statement is valid until another On Error statement in the line of execution is encountered. This means that if Function A contains an On Error statement, and Function A calls Function B, but Function B does not contain an On Error statement, the error handling from Function A is still valid. Therefore, if an error occurs in Function B, it is the On Error statement in Func
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 example jquery fixed header with scroll jQuery Image Slider With An Accordion getElementById in vbscript with example endswith, startsWith, contains functions in Javascript Please enable JavaScript to view the comments powered by Disqus. facebook Subscribe Enter Email address : google connect Category AnimalsArtCars MotorcycleEducationKidsGalleryFunny
