[Boost-users] Compiler's telling me a Boost class isn't a class.

Hi all. Just started using Boost, and these three lines (which compile in another project) fail here: // Get a list of endpoints corresponding to the server name. tcp::resolver theResolver(boost::asio::io_service); tcp::resolver::query query("10.10.10.10", "http"); tcp::resolver::iterator endpoint_iterator = theResolver.resolve(query); The compiler gripes thus: error: request for member 'resolve' in 'theResolver', which is of non-class type 'boost::asio::ip::basic_resolverboost::asio::ip::tcp > ()(boost::asio::io_service)' "using boost::asio::ip::tcp;" appears in an earlier included file. I don't see why this would work elsewhere and not here. Anybody have a guess as to what the problem is? Thanks!
