angular - Angular2 Routing: what does it mean that it creates an instance of the component associated? -


i'm teaching myself angular2 , text i'm looking @ says:

the router locates or creates instance of component associated route, , component’s view displayed in location defined routeroutlet directive.

the code example: 

import { component } 'angular2/core'; import {productlistcomponent} './products/product-list.component'; import {productservice} './products/product.service'; import {http_providers} 'angular2/http'; import {router_providers, routeconfig, router_directives} 'angular2/router'; import 'rxjs/rx'; //load features import {welcomecomponent} './home/welcome.component' @component({     selector: 'pm-app',     template:`     <div>         <nav class='navbar navbar-default'>             <div class='container-fluid'>                 <a class='navbar-brand'>{{pagetitle}}</a>                 <ul class='nav navbar-nav'>                     <li><a [routerlink]="['welcome']">home</a></li>                     <li><a [routerlink]="['products']">product list</a></li>                 </ul>             </div>         </nav>         <div class='container'>             <router-outlet></router-outlet>         </div>     </div>`,     directives: [router_directives],     providers: [productservice, http_providers, router_providers] }) @routeconfig([     {path: '/welcome', name: 'welcome', component: welcomecomponent, useasdefault: true },     {path: '/products', name: 'products', component: productlistcomponent} ]) export class appcomponent {     pagetitle: string = "acme product management"; }

the question is: can see locate part mean creates instance of component associated? {} , if display in associated routeroutlet directive?

you have routeconfig annotation consist 2 config objects:

{path: '/welcome', name: 'welcome', component: welcomecomponent, useasdefault: true }, {path: '/products', name: 'products', component: productlistcomponent}

each of object has it's own path /welcome , associated component welcomecomponent, instance.

if going /welcome location, angular put associated path component - welcomecomponent in place <router-outlet></router-outlet> directive included in html.

as result have injected component in it's own html , logic in specific place.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
