Re: [Boost-users] [serialization] different behaviour betweenxml_wiarchive and binary_wiarchive

Nachrichtall archives are meant to work alike.

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.

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?

***
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
