[python-win32] win32com calling C++ COM interface

[Shad Muegge]

Hi,
 I've just started looking at Python. I am trying to resolve an issue a user
is having trying to access the COM interface in our application from Python.
 C++ code:
 STDMETHODIMP
CMyClass::Read(
const int x,
 VARIANT *indexlist, // IN: "safe" array of 4-byte integers
VARIANT *results)
  Python code:
  def read(self, x, addr):
try:
addr = buffer(array.array('L', addr))
data = self.__Api.Read(x, addr)
...
 x.read(0, 0x12345678)
 The variant that shows up on the C++ code is a safearray of 1-byte integers
with 4 elements: 12, 34, 56, 78.
 The API treats them each as individual "addresses"...
 Here's the COM definition from the .py file.
  def Read(self, x=defaultNamedNotOptArg, indexlist=defaultNamedNotOptArg,
results=pythoncom.Missing):
"""method Read"""
return self._ApplyTypes_(2, 1, (24, 0), ((3, 1), (16396, 1), (16396, 2)),
'Read', None,x
, indexlist, results)
 Thanks,
Shad
