i want information each wifi network name , noise / strength.can body tell me how it.

not sure if understand question. try make little bit more clear.

anyway, here's think understood.

nsstring *path = [[nsbundle mainbundle] pathforresource:@"/users/admin/desktop/wi-fi" oftype:@"txt"]; nsarray *categories = [nsarray arraywithcontentsoffile:path]; (nsdictionary *category in categories) {     nslog(@"%@", [category objectforkey:@"interfaces"]);     nslog(@"%@", [category objectforkey:@"software versions"]); }

i haven't ran think should work, give shot. similar you're looking for. if not, it's in right direction , brings step closer finding answer. happy coding!

edit:

drag text file project , following

nsstring *path = [[nsbundle mainbundle] pathforresource:@"nsdictionarytextfile" oftype:@"txt"]; nsstring *content = [nsstring stringwithcontentsoffile:path encoding:nsutf8stringencoding error:null]; nsarray *testarray = [content componentsseparatedbystring:@"\n"]; nsstring *topdictionary = @""; nsmutabledictionary *dict = [nsmutabledictionary dictionary]; nsmutabledictionary *finaldict = [nsmutabledictionary dictionary]; for(nsstring *s in testarray){     nsarray *newarray = [s componentsseparatedbystring:@":"];     if([newarray[1] isequaltostring:@""]){         if([dict count] == 0){             topdictionary = newarray[0];         }         else{             topdictionary = [topdictionary stringbytrimmingcharactersinset:[nscharacterset whitespaceandnewlinecharacterset]];             [finaldict setobject:[dict copy] forkey:[topdictionary copy]];             [dict removeallobjects];         }     } else{         nsstring *object = [newarray[1] stringbytrimmingcharactersinset:[nscharacterset whitespaceandnewlinecharacterset]];         nsstring *key = [newarray[0] stringbytrimmingcharactersinset:[nscharacterset whitespaceandnewlinecharacterset]];         [dict setobject:object forkey:key];     } } topdictionary = [topdictionary stringbytrimmingcharactersinset:[nscharacterset whitespaceandnewlinecharacterset]]; [finaldict setobject:dict forkey:topdictionary]; nslog(@"finaldict: %@", finaldict);

* please not not finished ! have figure out more logic *

don't know how want them should give on how should work. didn't figure out complete logic adding top level dictionary , sub level dictionary should put in right directions. start removing trimming put in top dictionary , check empty/white space in front of string , use figure out dictionary supposed go. ie no empty space means highest 1 , more white spaces "inner" in dictionary. hope helps started.

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...
