(OP)
Hi,

I've bought a book, "Pure CORBA" by Fintan Bolton, and am trying to work through the examples.  I got the first one working, major time drain.  I'm spending a lot more time just getting the stuff compiled and linked than I am learning CORBA.  Hopefully that's going to change.

Using Visual Studio 6, ACE+TAO.

There's a file read_reference which is supposed to read a really huge string from a file.  The code goes like this:

CORBA::String_var strV;

fstream ifs ("ior.txt");

ifs >> strV;//appears to be the offending line

with the ifs line in the code I get a Link2001 error.  It's a huge error text message but what's going on appears to be that there's not a >> overloaded for the CORBA::String_var type?  I eventually hacked around the problem by commenting out the line and hardcoding some file stuff but would like to understand why this won't work.  Simply casting strV to a string didn't work.  Is my configuration faulty?

Does anyone else on the list use Fintan's book with Visual Studio and ACE+TAO?  I'm thinking that might be the problem.

I'm rambling so I'll stop writing at this point.

Thanks,
Frank
