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

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.

Caution
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

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Using the connection object from step one, get a site control file resource. For more information, see About the Configuration Manager Site Control File.
Get the SMS_EmbeddedPropertyList for the required embedded property list.
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.

To view code that calls these functions, see How to Read and Write to the Configuration Manager Site Control File by Using Managed Code or see How to Read and Write to the Configuration Manager Site Control File by Using WMI.

The sample method has the following parameters:

Parameter	Type	Description
Resource	Managed: IResultObject VBScript: SWbemObject	The site control file resource that contains the embedded property.
propertyListName	Managed: String VBScript: String	The embedded property list to be read.
Values	Managed: String array VBScript: String array	The SMS_EmbeddedProperty class Values property. An array of string values.
