You delete a software metering rule, in Microsoft System Center Configuration Manager 2007, by loading the instance of the software metering rule that is identified by the software metering rule ID and calling the delete method.

To delete a software metering rule

Set up a connection to the SMS Provider.
Load the software metering rule object by using the SMS_MeteredProductRule class and a known software metering rule ID.
Delete the software metering rule by using the delete method.

Example

The following example method shows how to delete a software metering rule by loading an instance of the software metering rule that is identified by the software metering rule ID and calling the delete method.

Important

The rule ID corresponds to the value stored in the property RuleID. The Configuration Manager 2007 console displays a Rule ID column, which actually corresponds to the value stored in the property SecurityID.

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

' Delete a software metering rule.
 Sub DeleteSWMRule(connection,                  _
                   existingSWMRuleID)                         

    ' Get an existing software metering rule to delete. 
    Set existingSWMRule = connection.Get("SMS_MeteredProductRule.RuleID='" & existingSWMRuleID & "'")  
    
    ' Get file name for output.
    fileName = existingSWMRule.FileName
       
    ' Delete the software metering rule.
    existingSWMRule.Delete_
    
    ' Output a success message.
    Wscript.Echo "Deleted SWM rule: " & existingSWMRuleID
    Wscript.Echo "Rule name: " & fileName
                                   
 End Sub

public void DeleteSWMRule(WqlConnectionManager connection,
                          string existingSWMRuleID)
{
    try
    {
        // Get the specific SWM Rule to delete.

        IResultObject existingSWMRule = connection.GetInstance(@"SMS_MeteredProductRule.RuleID='" + existingSWMRuleID + "'");

        // Get file name for output message.
        string fileName = existingSWMRule["FileName"].StringValue;

        // Delete the software metering rule.
        existingSWMRule.Delete();

        // Output a success message.
        Console.WriteLine("Deleted SWM rule: " + existingSWMRuleID);
        Console.WriteLine("Rule name: " + fileName);
    }

    catch (SmsException ex)
    {
        Console.WriteLine("Failed to delete the software metering rule. Error: " + ex.Message);
        throw;
    }
}

The example method has the following parameters:

Parameter	Type	Description
Connection	Managed: WqlConnectionManager VBScript: SWbemServices	A valid connection to the SMS Provider.
existingSWMRuleID	Managed: String VBScript: String	Identifies a specific software metering rule. In this case, identifies the specific software metering rule that will be deleted.
