Re: [Boost-users] [serialization] differentbehaviourbetweenxml_wiarchive and binary_wiarchive

Its hard to know without seeing more code. Often there is a problem when load/save don't match up. The easiest way to verify this is make sure it works with xml_?archive which checks that the begin/end tags match. Other than that I don't know what to say. Robert Ramey Oliver Mutz wrote:

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.
