c# - Exposing items in a ListBox through an Interface in MVP -

-

in mvp application presenter wants access / update data in list box on view. , presenter talking view through interface iview. i'm planing expose items in list box through property follows. have problem in using single property in case.

interface iview {     list<string> permission; }   class form : iview {     public list<string> permission     {         { return lstgivenpermissions; } // casting error         set { lstgivenpermissions.datasource = value; }     } }

so presenter should able access , update data in list follows

class presenter {     updatemodelfromview()     {         model.permission = view.permission;     }  updateviewfrommodel()     {         view.permission = model.permission;     } }

my model this

class model {     ipublic list<string> permission = new list<string>();     // }

i know above code not compiled due mismatches in datatypes. (casting errors).

could please let me know how can achieve this?

i looking this...

    public list<string> permission     {         { return lstgivenpermissions.items.cast<string>().tolist(); } //         set { lstgivenpermissions.datasource = value; }     }

and solved problem!!!

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()

-
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...
