angularjs - ui-router resolve is not working with the index page controller -

-

i want resolve value before load first page of application, kept telling me

unknown provider: programclasssummaryprovider <- programclasssummary <- homectrl

i pretty sure did correctly, because did same thing other controller , routing. not working homepage controller. seems load controller first, before resolved in routing. wrong code?

in routing.js

$stateprovider         .state('home', {           url: '/home',           controller: 'homectrl',           controlleras: 'vm',           templateurl: 'index_main.html',           resolve: {             programclasssummary: ['groupdatafactory', function (groupdf) {               return groupdf.getprogramclasssummary();             }]           },           ncybreadcrumb: {             skip: true           }         });

in controller.js

angular     .module('issmccapp')     .controller('homectrl', homectrl);    homectrl.$inject = ['$scope', '$location', '$state', '$auth', 'programclasssummary'];    /* @nginject */   function homectrl($scope, $location, $state, $auth, programclasssummary) {      var vm = this;      vm.isauthenticated = isauthenticated;     vm.programclasssummary = programclasssummary;      if (!$auth.isauthenticated()) {       $state.go('login');       return;     }      function isauthenticated() {       return $auth.isauthenticated();     }   }

in factory.js

 function getprogramclasssummary(showall) {       var query = "";       if (showall)         query = apiconfigobj.base_url + '/api/group/infor/programclasssummary?all=1';       else         query = apiconfigobj.base_url + '/api/group/infor/programclasssummary';        return $http.get(query)         .success(function (result) {           return result;         })         .error(function (err) {           return err;         })      }

i'd say, have distinguish ui-router state world, , angular itself. reason why defined here (extracted $resolve ui-router api documentation):

$resolve

resolve(invocables, locals, parent, self)

resolves set of invocables. invocable function invoked via $injector.invoke(), , can have arbitrary number of dependencies. invocable can either return value directly, or $q promise. if promise returned resolved , resulting value used instead. dependencies of invocables resolved (in order of precedence)

  • from specified locals
  • from invocable part of $resolve call
  • from invocable inherited parent call $resolve (or recursively
  • from ancestor $resolve of parent).

there a wroking plunker, uses index.html

<body ng-controller="rootctrl">      summary root:     <pre>{{summary}}</pre>      <ul>       <li><a href="#/home">home</a>       <li><a href="#/other">other</a>     </ul>      <div ui-view=""></div>

so, here use rootctrl, won't go through state machine ui-router, angular basic stuff

the root controller must defined as

.controller('rootctrl', ['$scope', 'groupdatafactory', function ($scope, groupdf) {    $scope.summary = groupdf.getprogramclasssummary(); }])

for state home, can use different approach, in fact same above (simplifed version below)

  .state('home', {       url: "/home",       templateurl: 'tpl.home.html',       resolve: {           programclasssummary: ['groupdatafactory', function (groupdf) {           return groupdf.getprogramclasssummary();         }]       },       controller: 'homectrl',   })

and controller able consume locals

.controller('homectrl', ['$scope', 'programclasssummary', function ($scope, summary) {    $scope.summaryforhome = summary; }])

check in action here

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
