PythonCOM Problem: Automating WinFAX from Python

[Stefan Schukat]

Hi Tino,

this is a property with an parameter. Since in Python is
no concept like call by reference. You have to use the
makepy generated wrapper (Either by makepy or EnsureDispatch) to call 
such a function. This wrapper translates the call to:

>>> Result, Status = appObj.GetAutoRecieve(Device, Status)

Why there is a typeerror depends on the implementing object.
I must have a look at the makepy wrapper to tell you more.

Hi Stefan!

Thanks a lot for your help! This really works now!
But it just raises the next question - maybe you or someone else can
help again? :-)

The function I want to use now on the "appObj" is "GetAutoRecieve()".
It's signature in C++ is

short GetAutoRecieve(LPCTSTR sDevice, short FAR * nStatus)

How can I code this in Python? How to emulate a pointer to an integer?

I tried

>>> nStatus = 0
>>> appObj.GetAutoReceive(u'MicroLink Office', nStatus)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "<COMObject <unknown>>", line 2, in GetAutoReceive
pywintypes.com_error: (-2147352571, 'Typkonflikt.', None, 2)
>>>

with or without unicode string and with/without using "id(object)"
(pointer type?) instead of the object itself. But I always get

 Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "<COMObject <unknown>>", line 2, in GetAutoReceive
pywintypes.com_error: (-2147352571, 'Typkonflikt.', None, 2)

Could you give me another hint?
Thanks a lot!
