c++ - Access to different struct with same name -


i'm trying implement workaround boost versions cause problems scoped enums on linking in c++11 mode: see https://svn.boost.org/trac/boost/ticket/6779 , https://svn.boost.org/trac/boost/ticket/10038

the problem simply: pre-distributed boost libs expose (namespaces stripped):
detail::copy_file(path const&, path const&, copy_option::enum_type, error_code*)
c++11 compilation tries find:
detail::copy_file(path const&, path const&, copy_option, error_code*)
due fact, c++98 boost uses emulated scoped enums, instead of c++11 ones.

i though might able write adapter put own object file , link program, failed naive approach:

#define copy_option native_copy_option__ #include <boost/filesystem/operations.hpp> #undef copy_option  namespace boost { namespace filesystem {      struct copy_option{         enum enum_type{none, fail_if_exists = none, overwrite_if_exists};     };  namespace detail {      void copy_file(const path& from, const path& to, copy_option::enum_type option, system::error_code* ec=0);      using copy_option = native_copy_option__;     void copy_file(const path& from, const path& to, copy_option option, system::error_code* ec)     {         copy_file(from, to, static_cast<boost::filesystem::copy_option::enum_type>(option), ec);     }  }  // namespace detail }  // namespace filesystem }  // namespace boost

the problem is: need define function c++11 enum in signature declare function c++98 enum has same name.

is somehow possible?

i think should write portable code.

conditionally compiling "competing" variants of code solicits odr violations , spurious abi incompatibility issues.

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
