Re: [boost] Re: Non-intrusive serialization with VC2003 (7.1)

I'm probably completely wrong, but but am I right in thinking the  
problem is due Jrs::SmartPtr<T> and not the fact that VS.NET or the  
serialization library is not find the right serialize method. If so I'm  
surprised no one else has pointed this out before!

It's clearly stated in the last string of emails that there is no  
serialize method defined for the smart pointer you are using, and  
therefore you need to write some code to serialise the smart pointer  
object that holds the message object. If you don't want to do this, and  
depending on the characteristics of your smart pointer class, and  
where/how it's referenced in your code (i.e. it could be as simple as  
changing a typedef and few other small pieces if you are lucky), you  
could try porting your code to use one of the boost smart pointers,  
such as boost::shared_ptr.

Anyway, forgive me if I'm wrong, and totally missing the point. Oh, on  
a completely off-topic note, I just realised Marcin that you're only a  
few miles down the road from me. I'm in based in Bournemouth.
