Connecting to running instances of IE on your computer (Python recipe) by Eric Koome
ActiveState Code (http://code.activestate.com/recipes/305273/)

This sample connects to the running instances of IE on your computer and prints out the URL, Cookie- if any, and the HTML content of the site. It can be extended to connect to running instances on another computer using DCOM and particularly using CoCreateInstanceEx(): Extend it as you wish and let me know how useful it has been to you!

"""
This sample connects to the running instances of IE on your computer and prints out
the URL, Cookie- if any, and the HTML content of the site.

You need to generate stub files for IE and MSHTML using the readtlb tool of ctypes.

python ctypes\com\tools\readtlb.py c:\winnt\system32\MSHTML.TLB > mshtml.py
python ctypes\com\tools\readtlb.py C:\windows\system32\SHDOCVW.DLL > ie6.py

Known Issues:
Filters out Explorer sinces we don't expect it to have HTML content or cookies. Explorer and IExplore are part of the Shell and therefore IShellWindows.

The mshmtl.py file must be fixed manually by inserting this at the top, otherwise you get NameErrors:
 
 LONG_PTR = c_long
 UINT_PTR = c_uint 
 wireHGLOBAL = wireHWND = wireHDC = wireHBITMAP = c_int 
 SAFEARRAY = POINTER # I"m quite sure this is wrong

usage:
python IEconnect.py

You need the good ctypes module from http://starship.python.net/crew/theller/ctypes/
