Hi Roger,
Thanks for the help. So now the program looks like:
import win32com.client
class HelloWorld:
_reg_clsid_ = "{4E797C6A-5969-402F-8101-9C95453CF8F6}"
_reg_desc_ = "Python Test COM Server"
_reg_progid_ = "Python.TestServer"
_public_methods_ = ['Hello']
_public_attrs_ = ['softspace', 'noCalls']
_readonly_attrs_ = ['noCalls']
def __init__(self):
self.softspace = 1
self.noCalls = 0
def Hello(self, WL ):
# In VB this looks like Public Sub Hello(ByVal objWL As
WealthLab.IWealthLabAddOn3)
WL = win32com.client.Dispatch(WL)
self.noCalls = self.noCalls + 1
# insert "softspace" number of spaces
return "Hello" + " " * self.softspace + str(self.noCalls) +
str(WL.BarCount())
if __name__=='__main__':
import win32com.server.register
win32com.server.register.UseCommandLine(HelloWorld )
The Python Trace Collector gives me:
Object with win32trace dispatcher created (object=None)
in _GetIDsOfNames_ with '('Hello',)' and '2048'
in _Invoke_ with 1002 0 3 (<PyIDispatch at 0x3d91824 with obj at 0x32eea00>)

You ought to be able to do
win32com.client.Dispatch(WL)
to get a usable com object.

How do I get the instance of the interface to have its methods? The
