The "struct" module is a very helpful tool when you're doing Win32 API 
programming like this, especially with the new changes that make it more 
difficult to manipulate binary values as dwords.  It would be worth your 
time to spend a few minutes playing with it, to figure out for yourself 
what it does.

For example, Win32 programmers are used to combining two 16-bit values 
into a 32-bit value using this C code (which also happens to be valid 
Python code):
    dword = (hi << 16) | (lo & 0xffff);

This gets you a deprecation warning in Python 2.3.  You can do this same 
function without the warning using struct:
    dword = struct.pack( "<HH", hi, lo )
