Don't know, but common sense tells me it's not a good idea! > However, now I will try to run the two instances on separate machines > and to synchronize them via network. Do you know how to start a second instance on a second machine over the network in python/COM (DCOM)? Is this possible directly with the win32com > package in python or do I have to install an additional package? Well, funnily enough, you use exactly the same call, but with a machine name on the end: <code> import win32com.client xl = win32com.client.DispatchEx ( "Excel.Application", "other_machine" ) </code> The trouble now is that, to use COM/DCOM effectively, you really need to know what to do, not just be a dabbler like me. On a recent thread, Alex Martelli recommended Don Box's "Essential COM" which I've noted down but haven't read: http://groups.google.com/group/comp.lang.python/msg/f95a2d51b6e84091?hl=en& That said, this is Python so even without using DCOM directly, you have a whole slew of across-the-network possibilities for interacting between apps on two machines. Just ask this list and sit back and wait for the variety of replies! TJG -- http://mail.python.org/mailman/listinfo/python-list
