(when i tried it it generated wrapper objects en masse but i simple wanted to pass around strngs.) don't know about BOOST or CXX cause i don't use C++ in my projects, but those get usualy mentioned for Python extensions with C++. maybe one of those could be very helpful for you. http://www.boost.org/libs/python/doc/ http://cxx.sourceforge.net/ chris -- Chris <cliechti at gmx.net>
