You handle synchronous errors, in Microsoft System Center Configuration Manager 2007, by inspecting the SWbemLastError object when an error occurs. An error has occurred when the error object Number property is non-zero.

Note

In VBScript you should declare that you want to resume running the script if an error occurs. Otherwise, the script will end when an error condition occurs. To do this, use the On Error Resume Next declaration in your script.

Example

The following VBScript example displays the most recent error information that is available from the SWbemLastError object. You can use the following code, which tries to get an invalid SMS_Package package to test it. For more information about getting the connection parameter, see How to Connect to an SMS Provider in Configuration Manager by Using WMI.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

Sub ExerciseError(connection)

    On Error Resume next

    Dim packages
    Dim package
    
    ' Run the query.
    Set package = connection.Get("SMS_Package.PackageID='UNKNOWN'")
    
    If Err.Number<>0 Then
        Call DisplayLastError
    End If
   
End Sub    

Sub DisplayLastError
    Dim ExtendedStatus
    
    ' Get the error object.
    Set ExtendedStatus = CreateObject("WbemScripting.SWBEMLastError")
     
    ' Determine the type of error.
    If ExtendedStatus.Path_.Class = "__ExtendedStatus" Then
        WScript.Echo "WMI Error: "& ExtendedStatus.Description            
    ElseIf ExtendedStatus.Path_.Class = "SMS_ExtendedStatus" Then
        WScript.Echo "Provider Error: "& ExtendedStatus.Description
        WScript.Echo "Code: " & ExtendedStatus.ErrorCode
    End If
End Sub
