I cannot comment on this question. > If not, does anyone have any suggestions > using comtypes?

I have at least started writing some docs, and posted links to the ctypes users list: This describes how COM interfaces are defined, used, and implemented in comtypes: http://svn.python.org/view/*checkout*/ctypes/trunk/comtypes/docs/com_interfaces.html and this describes the comtypes.client high-level module functionality: http://svn.python.org/view/*checkout*/ctypes/trunk/comtypes/docs/comtypes.client.html I hope these documents have some value. Also I'm willing to help you if you want to try out comtypes.
