For an event object, the event's source object at the time the event occurred. Note that the state of the object might be different from its prior or current state. To get the state of the source object prior to the event, use the OriginalObject property on subclasses of IObjectChangeEvent that provide this property.

For ICmSweepResult, the object that a sweep running in preview mode selected as a candidate for processing, or that a sweep running in normal mode failed to process.

Property SourceObject As IIndependentObject

IIndependentObject SourceObject { get; set; }

property IIndependentObject^ SourceObject {
	IIndependentObject^ get ();
	void set (IIndependentObject^ value);
}

function get_sourceObject();
function set_sourceObject(value);
