Summary: TypeError: 'unicode' object is not callable

Initial Comment:
python 2.3.5
pythonwin 204
using dynamic binding

Have TypeError: 'unicode' object is not callable while 
calling COM object function. Because 
CDispatch.__getattr__ returns empty unicode string 
instead of callable.

I made some dirty fix, please, see attach, there is some 
comments inside 

It is win32com\client\dynamic.py 

Pity I can't supply COM object to reproduce because it 
is proprietary.

The problem here is that Python tries to check if the
attribute name is a method or property by requesting a
property and handling the error that results.  Even though
Python asks specifically for a property
(INVOKE_PROPERTYGET), the object is treating it as a
function call and returning a string.  pythoncom therefore
assumes it is a simple property.  VB does it correctly as
its syntax prevents using functions as objects (eg, you
can't assign an object method to a variable).

There are 2 choices:
* Change the object to honour the invoke flags correctly.
* Call obj._FlagAsMethod("Method1", "method2", ...)

    And you will then be able to say

    obk.Method1()

Note: Visual Basic calls functions of that COM object 
correctly
