The variable types library assembly is referenced in both the publisher and subscriber classes. Could you please expalin how to implement this functionality. Thank you Serge

you can create a custom event args class like this: public class EventArgs : EventArgs { public EventArgs(T value) { m_value = value; } private T m_value; public T Value { get { return m_value; } } } and then use it to pass your value around like with the sample classes: public class Broadcaster { private event EventHandler EventArgs String >> m_handler; public event EventHandler EventArgs String >> Triggered { add { m_handler += value ;} remove { m_handler -= value ;} } public void FireEvent() { if ( null != m_handler) m_handler( this  new EventArgs string >( My Value ); } } public class Listener { public void OnEvent( Object sender EventArgs String > args) { string val = args.Value; // do something with value here; } } I hope this helps -Matt
