Hi, I started using filesystem, regex, and bind today. It's been interesting. I'm using Visual C++ 8.0 on an XP machine that has network filesystems mounted to it, some using letters (H:\, Y:\, etc.), some accessable via two slashes (//linden/temp/, etc). I'd like to peruse these using boost::filesystem. The following works: std::string t = "h:\\temp"; boost::filesystem::path p(t, boost::filesystem::native); but I can't get filesystem to work with the string "h:/temp"; std::string s = p.string(); // s = "h:/temp" bool b = boost::filesystem::portable_posix_name(s); //returns false b = boost::filesystem::windows_name(s); //returns false b = boost::filesystem::portable_name(s); //returns false b = boost::filesystem::portable_directory_name(s); //returns false b = boost::filesystem::portbale_file_name(s); //returns false b = boost::filesystem::native(s); //returns false Also, I'd like to do the following std::string q = "//linden/temp/"; boost::filesystem::path p2(q); Any help is appreciated. thanks, matthew
