In Microsoft System Center Configuration Manager 2007, you can read user-defined status messages, on the site server, by querying the SMS Provider.

To read a user-defined status messages

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Query the provider for the SMS_StatusMessage instances you want. As part of the query get the insertion string values from SMS_SMS_StatMsgInStrings and the attribute value from SMS_StatMsgAttributes.

Example

The following example reads error message status messages for the sample created in How to Report User-Defined Status Messages. Make sure the MyPackageID and MyApplication values in the query match in both samples.

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

Sub ReadErrorStatusMesage(connection)

    Dim queryWQL
    Dim message
    Dim messageSet
    Dim statusMessage
    Dim insertionString
    Dim attributes

    queryWQL = "SELECT b.Component, b.MachineName, b.MessageType, b.MessageID, " & _
            "       c.InsStrValue, d.AttributeValue " & _
            "FROM SMS_StatusMessage b " & _
            "     JOIN SMS_StatMsgInsStrings c ON b.RecordID = c.RecordID " & _
            "     JOIN SMS_StatMsgAttributes d ON c.RecordID = d.RecordID " & _
            "WHERE b.Component = 'MyApplication' " & _
            "AND   d.AttributeID = 400 " & _
            "AND   d.AttributeValue = 'MyPackageID' "
    
    Set messageSet = connection.ExecQuery(queryWQL)
    
    For Each message in messageSet
        
        ' Get the message objects.
        statusMessage = message.Properties_.Item("b")
        insertionString = message.Properties_.Item("c")
        attributes = message.Properties_.Item("d")
        
        ' Display the message details.
        WScript.Echo "Message: " + insertionString.Properties_.Item("insstrvalue")
        WScript.Echo "Component: " + statusMessage.Properties_.Item("Component")
        WScript.Echo "Machine: " + statusMessage.Properties_.Item("MachineName")
        WScript.Echo "MessageID: " + Cstr(statusMessage.Properties_.Item("MessageID"))
        WScript.Echo attributes.Properties_.Item("attributevalue")
        WScript.Echo
       
    Next                        

 End Sub

public void ReadErrorStatusMessage(WqlConnectionManager connection)
{
    try
    {
        string queryWQL = "SELECT b.Component, b.MachineName, " +
                "       b.MessageType, b.MessageID, " +
                "       c.insstrvalue, d.attributevalue " +
                "FROM SMS_StatusMessage b " +
                "     JOIN SMS_StatMsgInsStrings c ON b.RecordID = c.RecordID " +
                "     JOIN SMS_StatMsgAttributes d ON c.RecordID = d.RecordID " +
                "WHERE b.Component = \"MyApplication\" " + 
                "AND   d.AttributeID = 400 " +
                "AND   d.AttributeValue = \"MyPackageID\" ";

        IResultObject query = connection.QueryProcessor.ExecuteQuery(queryWQL);
        foreach (IResultObject o in query)
        {

            ManagementBaseObject  statusMessage = (ManagementBaseObject)o["b"].ObjectValue;
            ManagementBaseObject insertionString = (ManagementBaseObject)o["c"].ObjectValue;
            ManagementBaseObject attributes = (ManagementBaseObject)o["d"].ObjectValue;

            Console.WriteLine("Message: " + insertionString["insstrvalue"]);
            Console.WriteLine("Component: " + statusMessage["Component"]);
            Console.WriteLine("Machine: " + statusMessage["MachineName"]);
            Console.WriteLine("MessageID: " + statusMessage["MessageID"]);
            Console.WriteLine(attributes["attributevalue"]);
            Console.WriteLine();
        }
    }
    catch (SmsException ex)
    {
        Console.WriteLine("Failed to read status message: ", 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. For more information, see About the SMS Provider in Configuration Manager.
