Thanks for this tip! Unfortunately, the few times I tried running it,
there wasn't any output
before crashing, but I'll keep at it and see if it turns up anything.

I think because it is an interface, makepy only generated these v_table entries:
IMbtQuotesNotify_vtables_dispatch_ = 0
IMbtQuotesNotify_vtables_ = [
(( 'OnQuoteData' , 'pQuote' , ), 1610678272, (1610678272, (),
[ (36, 1, None, None) , ], 1 , 1
, 4 , 0 , 12 , (3, 0, None, None) , 0 , )),
(( 'OnLevel2Data' , 'pRec' , ), 1610678273, (1610678273, (), [
(36, 1, None, None) , ], 1 , 1
, 4 , 0 , 16 , (3, 0, None, None) , 0 , )),
(( 'OnTSData' , 'pRec' , ), 1610678274, (1610678274, (), [
(36, 1, None, None) , ], 1 , 1 , 4
, 0 , 20 , (3, 0, None, None) , 0 , )),
(( 'OnOptionsData' , 'pRec' , ), 1610678275, (1610678275, (),
[ (36, 1, None, None) , ], 1 , 1
, 4 , 0 , 24 , (3, 0, None, None) , 0 , )),
]
Is the custom of passing an object that implements an interface as an
argument to a COM function an unusual one? I've searched for other
COM functions that do this, and have yet to find any. The most common
way of registering an event sink for most COM applications seems to be
overriding the callback functions on a COM object directly.
Thanks for all your help!
