To write to the Configuration Manager 2007 site control file by using the managed SMS Provider, you get the site definition file by querying for the required resource or component. You then update the embedded property, embedded property list, or multi-string list as required.

Note

You can also use connection manager GetInstance to get the required resource or component.

The managed Configuration Manager 2007 manages the connection session to the site control file automatically for you. Therefore you treat the IResultObject objects returned from the query in the same way as you treat IResultObject objects retrieved from the SMS Provider.

To read and write to the site control file

Set up a connection to the SMS Provider. For more information, see How to Connect to an SMS Provider in Configuration Manager by Using Managed Code.
Use the Connection Manager QueryProcessor object ExecQuery or GetInstance method to get the required site control file resource or component IResultObject object.
Using the IResultObject update the site control file.
Use the IResultObject object Put method to commit the changes.

Example

The following C# example accesses the client agent component of the site control file and creates a dummy property, property list and multi-string list. It then removes the updates that were made. The example demonstrates how to query the site control file, make updates, and commit changes to the site control file. The methods that are used to update the various embedded property types are documented in the following topics.
