我正在尝试在Python的新线程中从dll创建一个COM对象 - 所以我可以在该线程中运行消息泵:

from comtypes.client import CreateObject
import threading

class MessageThread(threading.Thread):

    def __init__(self):
        threading.Thread.__init__(self)
        self.daemon = True

    def run(self):
        print "Thread starting"
        connection = CreateObject("IDMessaging.IDMMFileConnection")
        print "connection created"

a = CreateObject("IDMessaging.IDMMFileConnection")
print "aConnection created"
t = MessageThread()
t.start()

这是我得到的错误跟踪:

aConnection created
Thread starting
>>> Exception in thread Thread-1:
