Hi,
Thank you for the follow up. Perhaps I did not express my need clearly
enough, so I made this minimal example;
# https://gitlab.com/-/snippets/2155778
<https://gitlab.com/-/snippets/2155778>
import pythoncom
import sys
import threading
import win32com.client
import win32com.server.util
from win32com.server import localserver
def init_server():
pythoncom.CoInitialize()
localserver.serve(["{D390AE78-D6A2-47CF-B462-E4F2DC9C70F5}"])
class Main:
def __init__(self):
self.server = win32com.client.Dispatch("Minimal.Example")
self.server.parent = self # TypeError: must be real number, not Main
That exception is very odd and I should look into it - but the problem
here is that you are trying to set an attribute on a COM object which is
a Python instance, which doesn't really make sense. 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
