Thanks for your answer Robert, Some of the files that did not work with binary_wiarchive are working now with binary_i/oarchive. Unfortunately some still don't. I'm trying to figure out what the reason for the trouble might be. The exception_code changed 'unregistered_class' to 'stream_error', because in some occasions the istream fails.

binary_w?archive has not been maintained. It may or may not work. It really has no reason for being as far as I can tell. The problem is that the wide characters can included -1 which is confused with EOF. When I discovered this, it didn't see a way to work around it and didn't really understand how one could do binary i/o with wide character archives. I've just assumed I've missed something dumb and moved on.
For practical purposes, just use binary_i/oarchive.

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?
*** Nope, it is a goal that all archives work alike.
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.
Oliver
