I meet another problem. After i create some ClientCreate instance and let the reactor run , it works ok. But how could I send message when reactor is running? Because there are not only one services that twisted provide. And when I need send the messages i have told above , perhaps there are other service running , using the same reactor(becaus it's global), and obviously I can't stop it , re-create ClientCreator, then call reactor.run() to send the message.

Does Client Creator load protocol's "connectionMade" automatically , same as factory?
ClientCreator is just a shortcut for creating the factory and so forth manually. The event handlers (connectionMade, dataReceived, connectionLost) on the resulting protocol will be invoked as normal.
So yes, connectionMade will be called (assuming a connection is made, if the connection fails the Deferred returned from ClientCreator.connectTCP will have an error instead), but this isn't really anything to do with ClientCreator: once the connection is established, ClientCreator is not involved.
Experimenting with the example at http://twistedmatrix.com/projects/core/documentation/howto/clients.html#auto... might be a good idea.
The source code for ClientCreator is quite simple. Perhaps it would be worth reading and understanding that, so you can see how little code is involved. The definition of ClientCreator is found in twisted/internet/protocol.py: http://svn.twistedmatrix.com/cvs/trunk/twisted/internet/protocol.py?view=auto&rev=14194
