in bootstrap have fixed top nav bar , fixed bottom nav bar. want show large image in background between space of 2 nav bars , want cover width of window. how can dynamically height between navbars , width of window? window size may change depending on device.so need dynamic $(window).resize(function() { var top_nav_height = $("#id_of_top_nav").height(); var bottom_nav_height = $("#id_of_bottom_nav").height(); var window_height = $(window).height(); var height_of_open_space = window_height - (top_nav_height+bottom_nav_height); $("#id_of_img").css({ height:height_of_open_space+'px'; }); }); this fine if 0px padding , margin, if not values , subtract height_of_open_space before applying img height

i'm not sure if it's possible @ wonder if it's possible bind text box 2 different fields depending on value of third. suppose have carrier goes origin destination , has status of being on way or having arrived. because of business logic , way customer works want grid of orders this. #id orgin dest. status 101 b going 102 c d going 103 d going however, when order id e.g. 102 reaches status, point of destination should viewed in origin column , destination column should empty (or show next stop or whatever else), this. #id orgin dest. status 101 b going 102 d - done 103 d going so bind column origin field origin in data context if status going bind field destination if status done . if it's not possible, how can approach it? forced create new data type maps actual orders viewable orders? or add property view model isn't supported field rather renders value depending on status? here exa...

afaik, in scala, 1 can choose use either curly braces {} or parenthesis () sending arguments method. math.abs{-10} def fx(x: int) = x * x fx{10} list(1, 3, 5, 7) filter { _ > 5} so, why not applicable apply method in object list? list.apply{"a", "b"} // not compile when call method can pass parameters or inside parentheses or without them if has 1 argument. here fx {10} pass block of return type int {10} without parentheses. it's equivalent fx({10}) . here list(1, 3, 5, 7) filter { _ > 5} pass block { _ > 5} of return type int => boolean without parentheses. in both above cases last block statement legal expression. here list.apply{"a", "b"} pass without parentheses block {"a", "b"} equivalent list.apply({"a", "b"}) , "a", "b" statement illegal in scala.

i've asked question ( multiple errors while momoizing function inside function ) , i've got nice answer... but! understand little more javascript, i'd know if momoized function can written in style: function main () { function memoized_f(){ //memoizing code } } edit: please notice i'm not asking difference in code above, i'm asking if possible memoize second one! so, how rewrite this? function main() { var create_node = (function() { var memo; console.log("memo: " + memo); console.log("create_node") function f() { var value; if (memo) { value = memo.clonenode(); console.log("clone node"); console.log(value); } else { var value = document.createelement("div"); value.innerhtml = "hello"; console.log("new node"); console.log("value: " + value); memo = value; } r...

i calling c++ function c# using p/invoke, function has infinite loop (capturing frames file) should broken when event happened in c#. how can break loop (which terminates function)? i tried run function in thread in c#, , abort thread when termination needed. but abort function didn't work . thread thread = new thread(mymethod); thread.start(); // terminate function thread.abort(); //didn't respond probably safest way 2 things: expose function named (eg) stoprecording sets global variable inside native code inside main function, check value of global @ start of every loop iteration see if stoprecording has been called (and if so, break out of loop) this lets terminate naturally without requiring heavy-handed terminations.
