Hello,
I'm having trouble catching events from my multi threaded app. I'm using 
wxpython and running several threads under the main wxApp thread. One of the 
threads creates a COM object for an OPC server.  I'm using dispatchWithEvents() 
to get the COM object. When I do this the server will post an event to the 
OnDataChange() method in my application. 
 
Everything runs wonderfully when I create the COM object within the main thread 
(wxApp). However if I create it from within a sub thread then the OnDataChange 
is not being called.
 
My understanding of how multithreaded applications work is basic. I'm using 
queue's and threading.locks to safely manage data. However I don't understand 
how messages and events are handled in multi threaded apps with different 
apartments. The COM object I created is a client to an OPC server. I suspect 
the server lives in a different apartment and that I must handle how messages 
and events are passed between different threads/apartments. 
 
Where should I start reading to learn more and/or is there a standard way to 
assure my events get posted across apartments/threads?
 
thanks,
Jeff
