vb.net - Namespace conflicts in Asp.net MVC -

-

i long-time semi-professional asp.net programmer has made leap asp.net forms environment mvc. in process of re-developing 1 of web apps exists in forms mvc, , liking mvc environment , glad making leap.

but...am encountering issues, 1 namespaces.

so let's imagine following: 1) create new mvc 4 project called mymvcproject 2) create app_code folder , add new class1.vb file follows:

namespace mynamespace   public class class1       property myproperty string    end class end namespace

ok far good. want access class in controller or follows:

imports mynamespace  public class default1controller    inherits system.web.mvc.controller      function index() actionresult         dim obj new class1            return view()      end function end class

in asp.net forms environment, go. however, in mvc project unable import "mynamespace" , therefore unable create class1. go looking , find following in object browser:

>[other references...] v[vb] mymvcproject       >{}mymvcproject       >{}mymvcproject.my       >{}mymvcproject.my.resources v[vb] mymvcproject       v{}mynamespace          > [] class1 >[other references...]

so there's "mynamespace" , "class1." attempt revise code follows:

imports mymvcproject.mynamespace  public class default1controller    inherits system.web.mvc.controller      function index() actionresult         dim obj new class1            return view()      end function end class

but doesn't help. able reference first instance mymvcproject , it's sub-references. not second "class1" resides. uncertain how fix this.

update 1: found solution (but not explanation) whatever reason, asp.net mvc not me put stuff in app_code folder. however, if put class1.vb in models folder can can import "mymvcproject.mynamespace" , proceed normally. object browswer looks this:

>[other references...] v[vb] mymvcproject   >{}mymvcproject   >{}mymvcproject.my   >{}mymvcproject.my.resources   v{}mymvcproject.mynamespace      > [] class1 v[vb] mymvcproject >[other references...]

notice second reference mymvcproject still exists. "mynamespace" , classes put under first instance, can reference , import normally. kind of quirky, seems me. if have throw in models folder, well, i'll it.

update 2 had know problem putting stuff in app_code folder, have found answers: asp.net mvc using app_code directory

update 3

all mvc project default web application projects (wap) instead of web site projects. means there's no need app_code folder since waps compiled anyway. means *.cs files in project compiled, opposed web site projects *.cs files in app_code folder compiled.

update 4 , here how include app_code folder in mvc project:

you have go @ properties section of file , build action change content compile. ;)

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
