those used with VBScript. The primary difference is 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 & "

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|im

For details, see the following two sections: Handling Errors Using ADO Handling Errors Using OLE DB Handling Errors Using ADO The OLE DB error objects returned by the SAS Data Providers are presented in the ADO interface as Error objects. Because it is possible for more than one error to be returned, the errors are stored in the vbscript on error Errors Collection. To retrieve complete error information, you iterate through the Errors Collection and output the information. In most cases, the Description and Number properties of the Error object provide the most helpful information. The Visual Basic, VBScript and ASP examples all show how errors can be handled using ADO. The VBScript and ASP examples perform the same tasks as the Visual Basic example but there are language differences between them. When reviewing the sample code, keep the following differences in mind: An ASP file typically embeds VBScript and delimits the VBScript with <% and %> . VBScript does not predefine the ADO Enumerated Constants, so you must code them as constants. In VBScript, you should create objects using the CreateObject syntax. VBScript usually provides different output than Visual Basic. Usually, Visual Basic programmers handle errors using the On Error Goto syntax. However, this syntax is not supported by VBScript, so the VBScript and ASP examples use a subroutine to handle error output. Note: Although the examples use the Debug.Print and MsgBox methods to display error information, applications can use other methods such as Document.Write or Response.Write. You can also write an application that traps errors rather than

If a WinHttpRequest connection timeout or error occurs, or the remote server responds with an error, the error details are returned instead of the content. To use the code in an ASP page instead of WSH, replace "Wscript.Echo" with "Response.Write" and "CreateObject" with "Server.CreateObject".
