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 that VBScript does not support the concept of error handling by continuing execution at a label. https://msdn.microsoft.com/en-us/library/ms675540(v=vs.85).aspx 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 & ")" & "
" & _ " (NativeError: " & errLoop.NativeError & ")" & "
" If errLoop.HelpFile = "" Then strError = strError & _ " No Help file available" & _ "
" Else strError = strError & _ " (HelpFile: " & errLoop.HelpFile & ")" & "
" & _ " (HelpContext: " & errLoop.HelpContext & ")" & _ "

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 though a potentially fatal error has occurred. Ordinarily, all vbscript error handling 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 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 /
