That application has to handle xml files and for that I'm using win32com with with MSXML.<br>> <br>> My problem is, that apache spawns a new process / thread (not sure wether ist a process or thread. I think it's a thread) per http request. So when multiple users generated requests "at the same time" (new request before the first one is returned) I have multiple threads running. And that's where my win32com code is crashing...<br>> <br>> Currently, for every request my code does the following (as an example):<br>> <br>> return win32com.client.Dispatch("Msxml2.DOMDocument.6.0")<br>> <br>> To get an empty MSXSML DOM object.<br>> <br>> For multiple requests at the same time I get the following error:<br>> <br>> File "C:\Program Files\Apache Software Foundation\Apache2.2\TCRExceptionManagerData\database_library\database.py", line 24, in __init__<br>> self.__configFileSchema = self.__XSDSchemaCache()<br>> <br>> File "C:\Program Files\Apache Software Foundation\Apache2.2\TCRExceptionManagerData\database_library\database.py", line 1774, in __XSDSchemaCache<br>> return win32com.client.Dispatch("MSXML2.XMLSchemaCache.6.0")<br>> <br>> File "C:\Program Files\Python25\lib\site-packages\win32com\client\__init__.py", line 95, in Dispatch<br>> dispatch, userName = dynamic._GetGoodDispatchAndUserName(dispatch,userName,clsctx)<br>> <br>> File "C:\Program Files\Python25\lib\site-packages\win32com\client\dynamic.py", line 98, in _GetGoodDispatchAndUserName<br>> return (_GetGoodDispatch(IDispatch, clsctx), userName)<br>> <br>> File "C:\Program Files\Python25\lib\site-packages\win32com\client\dynamic.py", line 78, in _GetGoodDispatch<br>> IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.IID_IDispatch)<br>> <br>> com_error: (-2147221008, 'CoInitialize has not been called.', None, None)<br>> <br>> I've read already a bit in this mailing list and someone mentioned that one need to call pythoncom.CoInitialize() and pythoncom.CoUninitialize(). But I don't know where exactly i should call those functions and wether that'll solve my problem... Also, when I do a 'import win32com.pythoncom' I get an error that the module 'pythoncom' does not exist!<br>> <br>> I would be really happy if someone could help me and tell me how to make my win32com work for multiple threads!<br>> <br>> Greetings<br>> Dominique<br>> <br>> _______________________________________________<br>> python-win32 mailing list<br>> python-win32@python.org<br>> http://mail.python.org/mailman/listinfo/python-win32<br><br /><hr />Get 5GB of online storage for free! <a href='http://skydrive.live.com/' target='_new'>Get it Now! </a></body>
