That works, thank you. I'm relieved to finally move forward with this. Revised example;

What you want is to > set it to a COM object - which `self` is not. So something like: > > > class Main: > _public_methods_ = ["pong"] > def __init__(self): > self.server = win32com.client.Dispatch("Minimal.Example") > self.server.parent = win32com.server.util.wrap(self) > self.server.Ping() > > def pong(self): > return "pong" > > works. Sadly another paper-cut here is that the server just sees this as > a plain IDispatch object rather than a `Dispatch` wrapper - so `Ping` > needs to look something like: > > def Ping(self): > parent_as_object = win32com.client.Dispatch(self.parent) > print(parent_as_object.pong()) > > I guess you could, say, change `parent` into `set_parent()`, or > intercept via __setattr__() and do the wrapping just once. > > HTH, > > Mark >
