In Microsoft System Center Configuration Manager 2007, you write an embedded property to a site control file resource by either updating the property's SMS_EmbeddedObject object if it already exists, or by creating and adding a new SMS_EmbeddedObject object property to the resource's array of properties (Props parameter).

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

Value	Description
PropertyName	The embedded property name.
Value	An integer value
Value1	A string value
Value2	A string value

Warning

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

To write a site control file embedded property

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_EmbeddedProperty for the required embedded property or, if it does not exist, create the SMS_EmbeddedProperty object.
Populate the SMS_EmbeddedObject object.
Update the resources properties with the SMS_EmbeddedObject object.
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 property to a supplied site control file resource. The example works by finding the embedded property in the resource and then by updating the embedded property details. If the embedded property does not exist, it is created, and then added to the list of existing resource embedded properties.

            vProperty.Value = value

        ' If the props array does not exist, create it.
        If ISNull (resource.Props) Then
            resource.Props = array(embeddedProperty)
        Else   
            ' Grow the array and add the property.
            dim properties
            properties = resource.Props
            Redim Preserve properties(UBound(properties) + 1)
            Set properties(UBound(properties)) = embeddedProperty
            resource.Props = properties
        End If 
        resource.Put_,context
    End If
End Sub

public void WriteScfEmbeddedProperty(
    IResultObject resource,
    string propertyName,
    int value,
    string value1,
    string value2)
{
    try
    {

        // Properties
        Dictionary<string, IResultObject> EmbeddedProperties = resource.EmbeddedProperties;

        // Get the property, or create it.
        IResultObject ro;
        if (EmbeddedProperties.ContainsKey(propertyName))
        {
            ro = EmbeddedProperties[propertyName];
        }
        else
        {
            ConnectionManagerBase connection = resource.ConnectionManager;
            ro = connection.CreateEmbeddedObjectInstance("SMS_EmbeddedProperty");
            EmbeddedProperties.Add(propertyName, ro);
        }

        ro["PropertyName"].StringValue = propertyName;
        ro["Value"].IntegerValue = value;
        ro["Value1"].StringValue = value1;
        ro["Value2"].StringValue = value2;

        resource.EmbeddedProperties = EmbeddedProperties;

        // Commit the change.
        resource.Put();
    }
    catch (SmsException e)
    {
        Console.WriteLine("Failed to write property: " + e.Message);
        throw;
    }
}

The example method has the following parameters:

Parameter	Type	Description
Connection	Managed: WqlConnectionManager VBScript: SWbemServices	A valid connection to the SMS Provider.
swbemContex (VBScript)t	VBScript: SWbemContext	A valid context object.
Resource	Managed: IResultObject VBScript: SWbemObject	The site control file resource that contains the embedded property.
propertyName	Managed: String VBScript: String	The embedded property to be written to.
Value	Managed: Integer VBScript: Integer	The SMS_EmbeddedProperty class value property value.
Value1	Managed: String VBScript:String	The SMS_EmbeddedProperty class value1 property value.
Value2	Managed: String VBScript: String	The SMS_EmbeddedProperty class value2 property value.
