Ok, I've downloaded and extracted the dll from the rar file in the above
url, and - no problems here (except that winzip doesn't handle rar
files):

>>> from ctypes import *
>>> windll.HelloWorldDll
<WinDLL 'HelloWorldDll', handle 860000 at 982800>
>>> windll.HelloWorldDll.SayHello
<ctypes._StdcallFuncPtr object at 0x009248C8>
>>> windll.HelloWorldDll.SayHello()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ValueError: Procedure probably called with not enough arguments (4 bytes missing)
>>> windll.HelloWorldDll.SayHello("Thomas")
1547976
>>> windll.HelloWorldDll.SayHello.restype = c_char_p
>>> windll.HelloWorldDll.SayHello("Thomas")
'Hello Thomas'
>>> ^Z

PS: I noticed you used the ctypes-devel list for this msg, ctypes-users
would be the 'correct' list to use ;-).
