c++ - TinyXML issue with VC++ -

-

i collecting netstat information. program working when in tinyxml tag shows null while in console application same program runs successfully

char command[50];  tixmlelement* msg31 = new tixmlelement( "port" ); tixmlelement childtext0( "type" ); tixmlnode* childnode0; cstring stemp;  strcpy( command, "netstat -aon | findstr 3306" );  stemp.format(_t("%s"), system(command)); childtext0.value = "mysql_port" ;            childtext0.linkendchild(new tixmltext(getchararray(stemp))); childnode0 = msg31->insertendchild( childtext0 );                childtext0.clear(); net->linkendchild(msg31);

this program runs sucessfully. problem in xml shows null value. output of xml below. problem code?

output of xml(you can see mysql_port null)

            <network>             <port>                 <mysql_port>(null)</mysql_port>             </port>         </network>

the return value of system() int, more exit code of executed program, supposed 0 if program succeeds.

so, yes, null pointer there.

see this question on how output itself.

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...
