Hello,

          Errr, worked it out by reading the PyDoc in the source file.  
I'm using getevents to create an object (still unsure about the 
DispatchWithEvents - pass in a class definition : how do I get a 
reference to the instance?).

    Anyways - I have a new problem, the object for the events - the 
events are not being fired on this instance, ie the methods on mt event 
object instance are not being called.  Needless to say I've created the 
same implementation using other methodologies to check if the ActiveX 
component works (VB6) and I'm having no problem.  Don't know if it 
matters but the component is an Out Of Process component (ie an exe).

    Thanks for listening.

Cheers,

Neil
