Changed my use of QAxObject to QAxWidget and now at least I'm getting 
error messages.  First one is:

     QAxBase: Error calling IDispatch member Open: Exception thrown by 

I suspect this is because I'm not suppling a full set of parameters to 
Open(). (I had assumed defaults would be used when parameters are 
omitted, as they are with win32com).  I'll test that theory next.

But, before moving on, ...

Why doesn't QAxObject work?   "ADODB.Stream" has no UI.

And, just as importantly, why does QAxObject fail silently?
