I am trying to expose a couple Numpy functions to excel. Namley
Numpy.linalg.inv and Numpy.array.dot. I have successfully accessed
the following com server from within excel with CreateObject
========================================================================
test_com.py
========================================================================
from numpy.linalg import inv
from numpy import asarray
from win32com.client import Dispatch
class NevcoModule:
_public_methods_ = [ 'MInverse', 'MMult', "TestInstall" ]
_reg_progid_ = "Nevco.Modules"
_reg_clsid_ = "{79D06C97-331A-4BF8-824A-8DA3B618F8DB}"
def TestInstall(self):
return "Yes"
def MInverse(self,arg):
myarg = asarray(arg)
i = inv(myarg)
return i
def MMult(self,M1,M2):
mM1 = asarray(M1)
mM2 = asarray(M2)
x = mM1.dot(mM2)
return x
if __name__=='__main__':
import win32com.server.register
win32com.server.register.RegisterClasses(NevcoModule)
interp = Dispatch("Nevco.Modules")
raw_input("Leave running and then press enter to exit.")
win32com.server.register.UnregisterClasses(NevcoModule)
========================================================================
I then have a function in VBA inside excel which accesses this server
with Obj = CreateObject("Nevco.Modules"). I would like to share this
code with a couple coworkers who are not interested in learning
python, so I would like to create an executable to start the server
for them. My py2exe setup.py look like
========================================================================
setup.py
========================================================================
from distutils.core import setup
import py2exe
setup(
name="Nevco Excel",
version="0.1",
description='Functions to use inside excel.',
author='Bill Purcell',
author_email='bpurc...@nevco.com',
com_server=["win32com.servers.interp"],
options = {'py2exe': {'includes': 'numpy'}},
)
========================================================================
Unfortunately when I run the test_com.exe generated from python
setup.py py2exe, I get a "Cannot Create Object" error. I can't
remember the exact error but that is pretty close. When I run the
function excel just hangs and a console displays with the text about
installing the "Nevco.Modules" object. What is the right approach to
exposing com servers to be accessible via py2exe to VBA?
Also, I would like to eventually move towards maybe writing an
Add-in. Does anyone have any "Hello World" excell Add-in tutorials
for Python?
I know these topics are slightly redundant in the list but I couldn't
find any good answers.
Regards,
Bill
