Hi all,
I found a thread that it similar to what I'm looking for:
http://mail.python.org/pipermail/python-win32/2002-November/000562.html
but I couldn't come up with a solution...
I have a C++ server with a COM interface, which I can access via JScript
without any problem, but when it comes to Python, it seems impossible to
pass an array from the server to the Python script by reference.
C++ method declaration (the method just copies BufIn into BufOut):
STDMETHODIMP CoServer::EchoArray(
VARIANT BufIn,
VARIANT * BufOut,
ULONG* retVal)
IDL:
[id(1), helpstring("method EchoArray")] HRESULT EchoArray(
[in] VARIANT BufIn,
[out] VARIANT* BufOut,
[out,retval] ULONG* retVal);
for this one, I tried to replace "[out] VARIANT* BufOut" by "[in,out]
VARIANT* BufOut" or by "[in] VARIANT BufOut" without any success.
Python script:
import win32com.client
import time
import os
Server = win32com.client.Dispatch("MyObject.Server")
ans = [1,2,3]
Server.EchoArray([0x11,0x22,0x33], ans)
print ans
# I am expecting ans=[0x11,0x22,0x33]
# but ans remains as defined earlier ans=[1,2,3]
Does anyone know how to pass an array by reference from a COM
interface to a Python script?
Thank you!
Ben
