How to Handle Configuration Manager Asynchronous Errors by Using WMI

In Configuration Manager, when an error occurs in an asynchronous call, the error object is passed as the second parameter to the OnCompleted method. Inside your OnCompleted implementation, you check the error object the same as you would for a synchronous call.

You determine if there is an error by checking the HResult parameter of the OnCompleted method.

Example

This VBScript sample displays error information if there is a error during an asynchronous operation. To test, change the query to an invalid query such as Select * From ?????.

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

Sub sink_OnCompleted(HResult, oErr, oCtx)  
    WScript.Echo "All collections returned"  

    if HResult <> 0 Then   
    ' Determine the type of error.  
        If oErr.Path_.Class = "__ExtendedStatus" Then  
            WScript.Echo "WMI Error: "& oErr.Description              
        ElseIf ExtendedStatus.Path_.Class = "SMS_ExtendedStatus" Then  
            WScript.Echo "Provider Error: "& oErr.Description  
            WScript.Echo "Code: " & oErr.ErrorCode  
        End If  
    End If      
    bdone = true  
End sub  

.NET Framework Security

Using script to pass the user name and password is a security risk and should be avoided where possible.
