i create background task synchronize data server background task using windows runtime component in uwp app. but, unable access methods , classes project in windows runtime component in uwp. is there alternate way create background task without windows runtime component? or how can able access classes. you can create class library , add reference winmd , project class. code of class library like: public class bridgeclass { public static event action<string> messagereceived; public static void broadcast(string message) { if (messagereceived != null) messagereceived(message); } } inside project class can subscribe event bridgeclass.messagereceived += showmessage; and make realization: void showmessage(string msg) { } now winmd class call it: bridgeclass.broadcast("some value");

how tell if 1 element above (like after z indexes calculated) results queryselectorall. don't think there easy solution, in there browser api call , element "z-height". you approach problem how rendering engine working, stacking elements 1 on top of other based on dom tree depth. there css engine, changes element positions based on tag types , special rules css, such z-index , special position properties ( relative , absolute , etc.) , css "quirks", example z-index + opacity changes how elements stacked. based on goal, simplify parsing , ignore css doing , take html in consideration. there have dom api, makes traversing tree structure super easy , dom rendering engine handle weird cases of wrong-but-still-working markup.

as understand it, long double in c++ leverages hardware architecture (at least architectures). bigdecimal in java small enough inputs? does bigdecimal in java small enough inputs? no, , not. floating-point numbers lossy, while every bigdecimal has associated precision, , can represent number below precision. there no "small enough input" can usefully rendered floating point number, because if happen have bigdecimal value can represented in floating-point notation, you'd hard-pressed sort of operations on value , maintain specified precision. put way, purpose of bigdecimal offer precision while sacrificing speed. runs contrary floating-point, sacrifices precision in favor of speed. it sounds you're asking if java offers way work long double sized floating-point numbers, , there not . can conclude fact it's not provided jdk authors have never felt necessary add language.

i have slider component nested in form in app. slider adjusts parameters live in redux store . normally, slider controlled, values set props passed down redux store . when slider moved, onchange dispatch action update store , , slider values change. however, in case, solution poses problems: the slider has 100+ steps, dragging 50% across means dozens , dozens of onchange events since slider isn't connected store , every onchange forces re-render on parent, props changing. eviscerates performance. so, i've implemented partial solution: the slider values live in slider's state, dragging re-renders slider onchange events. an afterchange event--which fires when user releases mouse after dragging slider, dispatch es new values store . however, parent has "reset" button should set slider's values initial state. so, how can communicate slider component parent it's time reset values? have parent's reset button whatever ne...
