Hi, I'm developing a windows application using boost libraries. Unfurtunately, some parameters of it are totally out of my control, nor I have the leverage needed to change it. Namely, - the application *must* use Visual C++ 9.0 runtime - the IDE to be used is capped at Visual Studio 2013 - to avoid problems with other related projects, the boost release should be 1.54.0 (here I have a modicum of liberty, as far as the previous two conditions are satisfied) I may live whit all of the above, however Intellisense has some glitches that are annoying me. For one, it appears unable to recognize the boost::asio::ip namespace. If I define a variable as, for instance boost::asio::ip::udp::endpoint ep; Intellisense marks 'ip' in red and keeps saying that ep is undefined (and consequently doesn't offer completion for its methods). I have tried including directly boost/asio/ip/udp.hpp and also putting an "using boost::asio::ip::udp" before the above definition as in #include <boost/asio/ip/udp.hpp> using boost::asio::ip::udp; udp::endpoint ep; but nothing changes (I'll gladly post a screenshot if I knew which is the accepted way to post images to this list). It should be noted that, aside from this and some analogous problems, Intellisense works fine, making the above even more annoying. Does anyone have a solution to this problem that do not violate the aforementioned constraints? Thanks in avance lc -- Leo Cacciari Aliae nationes servitutem pati possunt.
