i don't know what you are trying to do, but this is what i usually do.
create a base class with a static callback function. making it static will
give it a C signiture but still keep it in the class namespace. the problem
with callbacks is that windows wants a C signiture and not a C++ one. the
c++ has a "hidden" this pointer and thus doesn't work properly. regardless,
you can then have a single static function and derive all your classess off
the base to use that one static function instead of making new classes with
each class having it's own static callback.

aloha,
mike
