In my application I'm trying to serialize data alternatively to xml_wiarchive or binary_wiarchive.
 
Writing and reading XML works without any problems.
Binary writing seems to work too, but reading the file throws an exception with exception_code 'unregistered_class'.
 
What I do is reading the XML data, writing binary and reading binary back in.
 
I thought there should be no difference which kind of archive I use.
Am I missing a point?
 
I would be thankful for any hint.
 
I know that it is hard to guess where the problem might be without seeing any code, but I by now I was not able to create some simple example which shows the same behaviour.
 
I'm using Windows XP (SP2) with MSVC 8.0.
 
Thanks.
