in angular 1.4, using ngoptions directive populate <select> tag <option> tags based on object looks this: {black: '#000000', red: '#ff0000', ...} that works fine using ng-options="value key (key, value) in vm.colors" , want add class each option tag matches key (e.g. '.black', '.red'). thought find option elements , use addclass() , i'm having trouble getting elements. (note: i'm not using jquery , avoid adding this.) here jsfiddle. i expect able bind results of $element.find('option') view model , watch using $scope.$watch('vm.options', function() {...}) , when log vm.options console seeing empty array. am using $scope.$watch incorrectly here? issue $element ? elements within scope of ngoptions unreachable controller? or making stupid mistake? any appreciated...thanks in advance! the docs pretty clear dom manipulation should done in directive. use rule of thumb: if find mys

i analyzing retrofit on android , had question on callbacks vs not using them. under impression callbacks used success , failure responses client might desire. otherwise omit it. here example of retrofit interface without callback: public interface githubservice { @get("/users/{user}/repos") list<repo> listrepos(@path("user") string user); } and here example callback (i hope have right): public interface githubservice { @get("/users/{user}/repos") list<repo> listrepos(@path("user") string user,callback<repo> cb); } im confused on 2 things: the return value in interface list me should void because retrofit use gson convert json response repo pojo. have create repo pojo expect last piece of code instead: public interface githubservice { @get("/users/{user}/repos") void listrepos(@path("user") string user,callback cb); } what purpose of return value? my seco

an article clr via c# jeffery ritcher. "when calling virtual instance method, jit compiler produces additional code in method, executed each time method invoked. code first in variable being used make call , follow address calling object." my question additional code generated jit reside. the jit compiler uses internal code heap allocate memory store generated code. ultimately, code heap manager uses virtualalloc function allocate memory.

i have structure specified following member 1, 16 bits member 2, 32 bits member 3, 32 bits which shall reading file. want read straight file struct. the problem c compiler align variables m1, m2 , m3 word boundaries @ 32 bits since working on arm cortex m3 following struct declaration: typedef struct { uint16_t m1; uint32_t m2; uint32_t m3; }something; reading directly file put wrong values in m2 , m3, , reads 2 bytes too. i have hacked around , using following works fine: typedef struct { uint16_t m1; struct { uint16_t lo; uint16_t hi; }m2; struct { uint16_t lo; uint16_t hi; }m3; }something; however, looks dirty hack. cannot wishing cleaner way force compiler put halves of m2 , m3 in different words, sub-optimal may be. i using arm-none-eabi-gcc. know bit packing, unable work around optimisation. edit: turns out didn't know enough bit-packing :d what looking packed attrib

how set tab page class 'active' in dynamical created list? i have link 'toon alle' show records, when ik click link display different view. active tab remains on first link. <ul class="nav nav-pills sort-source" data-sort-id="portfolio" data-option-key="filter"> <li data-option-value="*" class="active"> <a href="#" ng-click="getallrequests(1)">toon alle</a> </li> @foreach ($categories $categorie) <li data-option-value=".{{$categorie->namen}}" class=""> <a href="#" ng-click="getrequests({{$categorie->id}})" data-id="{{$categorie->id}}">{{$categorie->namen}} </a> </li> @endforeach </ul> you can using custom facade or html macro if using laravel 4 . example assumes using named routes. y

i trying compile example sfml page http://www.sfml-dev.org/tutorials/2.3/start-cb.php (at bottom) i dowloaded version gcc 4.9.2 dw2, set needed (linker, directories) , compiled without errors. when application starts says needs .dll files copied them sfml/bin directory. says the procedure entry point __gxx_personality_v0 not located in dynamic link library libstdc++-6.dll (libstdc++-6 there copied mingw/bin) or the pro... _zst24__throw_out_of_range_fmtpkcz in same dll on sfml page there note: there multiple variants of gcc windows, incompatible each other (different exception management, threading model, etc.). make sure select package corresponds version use. if unsure, check of libgcc_s_sjlj-1.dll or libgcc_s_dw2-1.dll files present in mingw/bin folder. if mingw installed along code::blocks, have sjlj version. if feel version of gcc can't work precompiled sfml libraries, don't hesitate build sfml yourself, it's not complicated. i tried compile li

hi doing ui project in java. truncate string or sequence of character given string example: if 000101 user input output of string 101. p.s: occurrence of 0's before 1 may anything. please me!! i'm sure there many ways this, , encourage figure out way on own. here's 1 answer question: why not try take user input , keep cutting off first character of string until reach nonzero number? for example, let's have string called "userinput". while(userinput.substring(0,1).equals("0")) userinput = userinput.substring(1);
