Python COM server

[Dave]

I have been trying an example from the Python Programming on Win32 book on the lastest versions of python (2.3.3) and win32all (build 163). I create the COM object and try to call it from VB but i can't seem to create the child.

debugging = 1
if debugging:
from win32com.server.dispatcher import DefaultDebugDispatcher
useDispatcher = DefaultDebugDispatcher
else:
useDispatcher = None

class Parent:
_public_methods_ = ['CreateChild', 'KissChild']
_reg_clsid_= "{E8F7F001-DB69-11D2-8531-204C4F4F5020}"
_reg_progid_ = "PythonDemos.Parent"

def CreateChild(self):
child = Child()
print "Our Python child is", child
wrapped = wrap( child, useDispatcher=useDispatcher )
print "Returning wrapped", wrapped
return wrapped

def KissChild(self, child):
print "KissChild called with child", child
dispatch = win32com.client.Dispatch(child)
print "KissChild called with child named", dispatch.Name

child = umwrap(child)
print "The Python child is", child

class Child:
_public_methods_ = []
_public_attrs_ = ['Name']
def __init__(self):
self.name = "Unnamed"

if __name__ == '__main__':
import win32com.server.register
win32com.server.register.UseCommandLine (Parent, debug=debugging)


This is the error in the Python Trace Collector:

The COM object always seems to fail whenever I call a subclass saying that its not defined. I'm not to sure what the problem is. Any help would be appreciated.

Thanks
