OCX and PythonWin....

[andy.smith at iname.com]

Hi All,

I'm trying to use Pythonwin to host an OCX which provides realtime stock
quotes.

The code I've been using to access the OCX is based on
the 'webbrowser.py'
file in the pythonwin ocx demos directory. The OCX returns quotes to the
application by calling an 'OnDynamicQuoteResponse' method, in response
to a
call to ''SubmitDynamicQuote'. I thought I could catch the event by
mimmicking the way the webbrowser demo catches an 'OnBeforeNavigate2'
event.
Unfortunately though, my 'OnDynamicQuoteResponse' method is not getting
called.

When the OCX is initialised, it requires that the application 'register'
with it. An initial call to the IsRegistered() method returns 0. After
this,
my script calls the Register("MYAPP") method. After this, a further
call to
IsRegistered() returns a one, which signifies that the application has
successfully registered for service. I guess this means that the OCX is
correctly functioning, as I can successfully call its methods, it looks
like
it's just return events that aren't being caught.

Can anyone help?!

Cheers,

Andy.
