In Microsoft System Center Configuration Manager 2007, you write an embedded RegMultiString list to a site control file component or configuration resource by creating a SMS_Client_Reg_MultiString_List and adding it to the resource's RegMultiStringLists array property.

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

To write a RegMultiString 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_Client_Reg_MultiString_List for the required embedded property.

  4. Update the embedded property.

  5. Commit the changes to the site control file. For more information, see About the Configuration Manager Site Control File.

Example

The following example method writes an embedded RegMultiString list to a supplied site control file resource component or configuration resource (resource). The example works by finding the embedded RegMultiString list (valuetName) in the resource and then by replacing the existing values array (ValueStrings) with the supplied values array (valueStrings). If you want to add an item to an existing property values array, you must first get the array, resize it, and the add the new array element.

If the embedded property list does not exist, it is created and then added to the list of the existing resource embedded property list.
