Hi,
Wondering if someone can give me any pointers with a problem. Trying
to call COM objects from inside an XML-RPC server which is using
Python's threading (via SocketServer.ThreadingMixIn in the standard
library). Gettings errors like;
pywintypes.com_error:(-2147221020, 'Invalid syntax', None, None)
If I use a single threaded server, no problem. Only getting this
problem in combination with SocketServer.ThreadingMixIn.
Example of the server looks like;
#----------------------------------------------------
import SimpleXMLRPCServer, SocketServer
import win32com.client
class ThreadedXmlRpcServer(SocketServer.ThreadingMixIn,
SimpleXMLRPCServer.SimpleXMLRPCServer):
pass
def listProcesses():
cses = win32com.client.GetObject("WinMgMts:").InstancesOf("Win32_Process")
vals = []
for cs in cses:
val = cs.Properties_("Caption").Value
vals.append(val)
return vals
if __name__ == "__main__":
print listProcesses() # This works...
# This also works, if used - no threads...
# server = SimpleXMLRPCServer.SimpleXMLRPCServer(("localhost", 8001))
# This doesnt...
server = ThreadedXmlRpcServer(("localhost", 8001))
server.register_function(listProcesses)
server.serve_forever()
#----------------------------------------------------
And a client if anyone want's to try;
#----------------------------------------------------
import xmlrpclib
server = xmlrpclib.Server('http://localhost:8001')
print server.listProcesses()
#----------------------------------------------------
Apologies in advance if there's something obvious I've missed (like
COM + threading is only possible via the win32api methods) - it's more
than possible I'm guilty of clueless newbieness.
Many thanks
