IronPython and COM Interface

Hello,

I'm new to IronPython and COM so please bear with me.

I have a COM interface provided to me. I need to implement this
interface and pass it to a method as a way of implementing
'callbacks'.

However it appears that the methods of my interface object are never
called.

As a alternative, I implemented the interface in C# and then extended
the C# class in IronPython. However, on running the code, methods of
my C# class rather than the IronPython class are being called.

Can anyone advise? Is this possible in IronPython?

The code is listed below.

Regards,
Divya

		#self.conn.EnableSplash(False)
		self.orders = self.conn.OrderClient
		self.quotes = self.conn.Quotes
		self.events = MBEvents()

	def login(self, host=demo_host, user=demo_user, passwd=demo_pass):
		self.conn.DoLogin(host, user, passwd, '')
		print self.quotes.RemoteAddress, self.quotes.RemotePort
		self.quotes.AdviseSymbol(self.events, 'EUR/USD', 1|2|3|4)
