[python-win32] Implementing a python com server that is used by a python client

[Ulrich Mierendorff]

Hi,

I have implemented a simple com server called "TestServer" using the 
following mail as an example
http://markmail.org/message/vheujc2lijgwhhju#query:+page:1+mid:4lgd7lzzokglsckc+state:results
(but without multi-threading support)

Now I want to write a python client that should be able to connect to 
"TestServer" via COM and receive events. Connecting to the server and 
calling methods is easy: I just use win32com.client.Dispatch(..).

As far as I know I have to use DispatchWithEvents if I would like to 
receive events. This requires makepy registration, so I created an 
idl-file for the server, compiled it with midl to a tlb file and 
compiled this with makepy to a python file.

Now I thought everything should work. But it doesn't:

Z:\extension\test>testclient.py
<COMObject testproject.TestServer>
Traceback (most recent call last):
  File "Z:\extension\test\testclient.py", line 28, in <module>
    server = 
win32com.client.DispatchWithEvents("testproject.TestServer", 
TestServerEventHandler)
  File "C:\Python26\lib\site-packages\win32com\client\__init__.py", line 
256, in DispatchWithEvents
    raise TypeError("This COM object can not automate the makepy process 
- please run makepy manually for this object")
TypeError: This COM object can not automate the makepy process - please 
run makepy manually for this object

(I've attached a simple example client and server including the file 
generated by makepy)

Others seem to have similar problems

but I can't find a solution. Is it impossible? If yes, is there another 
way to connect a python client to a python com server with events?
