[python-win32] COM and threading

[June Kim]

Running the following code results in an attribute error:

Exception in thread Thread-1:
Traceback (most recent call last):
  File "C:\Python25\lib\threading.py", line 486, in __bootstrap_inner
    self.run()
  File "testcom.py", line 10, in run
    print self.ie.locationUrl
  File "C:\Python25\Lib\site-packages\win32com\client\dynamic.py", line 500, in
__getattr__
    raise AttributeError, "%s.%s" % (self._username_, attr)
AttributeError: InternetExplorer.Application.locationUrl

It seems like the COM object isn't properly passed to the new thread.
Any roundabouts?


#testcom.py
from win32com.client import *
import pythoncom
import time, threading, sys


class Work(threading.Thread):
    def run(self):
        pythoncom.CoInitialize()
        print self.ie.locationUrl
        pythoncom.CoUninitialize()

ie=DispatchEx("InternetExplorer.Application")
ie.Navigate("http://www.google.com")
while ie.Busy:
    time.sleep(0.1)
print ie.locationUrl
w=Work()
w.ie=ie
w.start()
w.join()
