On Error Resume Next Vbscript
"log something") then resume the next line of 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? On Error Resume myErrCatch 'Do step 1 'Do step 2
On Error Goto Line
'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 14:36 answered Oct 1 '08 at 14:11 Dylan Beattie 33.

This documentation is archived and is not being maintained. Handling Errors in VBScript There is little difference between the methods used in Visual Basic and those used with VBScript. The primary difference is https://msdn.microsoft.com/en-us/library/ms675540(v=vs.85).aspx that VBScript does not support the concept of error handling by continuing execution at a label. In other words, you cannot use On Error GoTo in VBScript. Instead, use On Error Resume Next and then check both Err.Number and the Count property of the Errors collection, as shown in the following example: Copy
Error Handling Example (VBScript)
<% Dim cnn1 Dim errLoop Dim strError On Error Resume Next ' Intentionally trigger an error. Set cnn1 = Server.CreateObject("ADODB.Connection") cnn1.Open "nothing" If cnn1.Errors.Count > 0 Then ' Enumerate Errors collection and display ' properties of each Error object. For Each errLoop In cnn1.Errors strError = "Error #" & errLoop.Number & "" & _ " " & errLoop.Description & "
" & _ " (Source: " & errLoop.Source & ")" & "
" & _ " (SQL State: " & errLoop.SQLState & ")" & "

Operators Index Colophon Error Handling Error handling does not involve finding errors in your scripts. Instead, use on error error handling techniques to allow your program to continue executing even 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 on error goto elements to error handling in VBScript. The first is the On Error statement, which informs the 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 Functio
