c++ - Getting country code for QLocale::Country -

-

i trying find country code given qlocale::country value. in manual have found function, similar: qlocale::name.

qstring qlocale::name () const

returns language , country of locale string of form "language_country", language lowercase, two-letter iso 639 language code, , country uppercase, two- or three-letter iso 3166 country code.

the second part of return value need, have constructed following function:

qstring getcountrycode(qlocale::country c) {     return qlocale(qlocale::anylanguage, c).name().split('_').at(1).tolower(); }

strangely enough, if call function following way:

qdebug() << getcountrycode(qlocale::canada);

it produce output:

"us"

i have expected "ca"! on other hand, if call like:

qdebug() << getcountrycode(qlocale::hungary);

then produce correct answer:

"hu"

what missing here? (i using qt 5.2)

in general, given feature want isn't directly available, please submit feature request on bugtracker.

apart that, you can't build qlocale object anylanguage. makes absolutely no sense -- qlocale object identifies specific locale. 1 should pick canada, fr_ca or en_ca?

solution: use

qlist<qlocale> locales = qlocale::matchinglocales(qlocale::anylanguage,                                                   qlocale::anyscript,                                                   qlocale::canada);

then take first of list (if exists) , extract country name doing.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
