How to Read a Configuration Manager Site Control File Embedded Property List

Applies To: System Center Configuration Manager 2007, System Center Configuration Manager 2007 R2, System Center Configuration Manager 2007 R3, System Center Configuration Manager 2007 SP1, System Center Configuration Manager 2007 SP2

In Microsoft System Center Configuration Manager 2007, you read an embedded property list from a site control file resource by getting the SMS_EmbeddedPropertyList object for the embedded object from the resources PropLists property array.

An embedded property list has the following properties that you can set. For more information, see SMS_EmbeddedPropertyList.

Value Description

PropertyListName

The embedded property name.

Values

An array of string values. Each array item represents a single property list item.

Warning

Making changes to the site control file can cause irreparable damage to your Configuration Manager 2007 site.

To read a site control file embedded property list

  1. Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.

  2. Using the connection object from step one, get a site control file resource. For more information, see About the Configuration Manager Site Control File.

  3. Get the SMS_EmbeddedPropertyList for the required embedded property list.

  4. Access the property list values by using the SMS_EmbeddedPropertyList object Values property array.

Example

The following example method populates the supplied values parameter with the Values array of the embedded property list (SMS_EmbeddedPropertyList) identified by the propertyListName parameter. true is returned if the embedded property list is found; otherwise, false is returned.

You can update the embedded property list values that are returned from this method by using the method in How to Write a Configuration Manager Site Control File Embedded Property List.

Function GetScfEmbeddedPropertyList(resource,  _
        propertyListName,               _
        ByRef values)

    Dim scfPropertyList

    If IsNull(resource.PropLists) = True Then
        GetScfPropertyList = False
        Exit Function
    End If    
    
    For each scfPropertyList in resource.PropLists
       if   scfPropertyList.PropertyListName = propertyListName Then
            ' Found property list, so return the values array.
            values = scfPropertyList.Values
            GetScfEmbeddedPropertyList = True
            Exit Function
        End If
     Next  
     
     ' Did not find the property list.
     GetScfEmbeddedPropertyList = False
End Function
public bool GetScfEmbeddedPropertyList(
    IResultObject resource,
    string propertyListName,
    out ArrayList values)
{
    values = new ArrayList();
    try
    {
        if (resource.EmbeddedPropertyLists.ContainsKey(propertyListName))
        {
            values.AddRange(resource.EmbeddedPropertyLists[propertyListName]["Values"].StringArrayValue);
            return true;
        }
    }
    catch(SmsException e)
    {
        Console.WriteLine("Couldn't get the embedded property list: " + e.Message);
    }
    return false;

}
