===================

The above code cannot be compiled in VS 2005. The compiler reports an
error message "Threading support unavaliable: it has been explicitly
disabled with BOOST_DISABLE_THREADS", What's the cause?

Who know the solution to it? Thanks in advance. Any help is appreciated.

Just read the boost thread documentation, particularly on
configuration:

http://boost.org/doc/html/thread/configuration.html#thread.configuration.implementation

According to the documentation, a VS project must include the
multithreaded version of the runtime in order to use boost threads.

Right. That's the OP's problem.

Furthermore, the #include directives should be:

#include <boost/config.hpp>
#include <boost/thread.hpp>

You don't need to manually include <boost/config.hpp>, and the
top-level <boost/thread.hpp> pulls in all the parts of the thread
library, which the OP may not want or need. There's no problem
including just <boost/thread/thread.hpp>, as the author of the library
does in his examples, found here:
