string - What is the recommended way to flatten a std::vector<CString> to a multi_sz using C++ / STL -


i want write list of strings (atl::cstring) stored in std::vector reg_multi_sz value in windows registry. know how in plain c (iterate once total length, allocate buffer, copy strings buffer separated "\0").

know tried following using stl (sorry have use vs2010 "for each"): 

std::vector<tchar> multiline_sz; each ( cstring entry in mystringlist ) {    tchar* buf = entry.getbuffer();    multiline_sz.insert(multiline_sz.end(), &buf[0], &buf[entry.getlength()]);    multiline_sz.push_back(l'\0'); } multiline_sz.push_back(l'\0');

this works, wonder if there more elegant or faster way using stl.

cstring::getbuffer() zero-terminated, it's valid do

for each ( cstring entry in mystringlist ) {    tchar const* buf = entry.getbuffer();    multiline_sz.insert(multiline_sz.end(), &buf[0], &buf[entry.getlength()+1]); }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
