win32com coclass_interfaces problem

[Cristian Hasbun from Chile]

I need a win32com guru please... 

i'm not python expert, but i understand mi trouble... 

Requirements: 
Hook EyesWeb 3.2.0 (http://www.eyesweb.org) COM Module with Python 
2.0.1 
i used win32com libraries and generate an early binding for module 
(using prog_id) 

the problem is the file generated has a Class EyeswebSystem that is a 
CoClassBaseClass with coclass_interfaces Like IEywApplication that is 
a DispatchBaseClass... 

after reading other post with similar problem i saw that the other 
problems are about coclass_interfaces with objects DispatchBaseClass 
only... 

i try 

""" 
import win32com.client 
Eyes=win32com.client.Dispatch('Eyesweb.Remotesystem') 
App=win32com.client.Dispatch(Eyes,resultCLSID='{clsid}') 
""" 

an have more accurate result 

""" 
>>> Eyes 
<COMObject Eyesweb.Remotesystem> 
>>> App 
<win32com.gen_py.EyesWeb System.IEywApplication instance at 
0x19740672> 
""" 

but i can't reach "EyesWeb System.IEywApplication.Methods()" yet 

with diferents try and error, i get com_errors like: 
'the server threw an exception' 
'invalid access to memory location' 

here is a link of my gen_py generated file, easy for understand class 
structure of the module with a browse class
