i think i've got relatively easy problem here on hands, having trouble getting work. let me preface saying i'm new dax. consider following powerpivot data model : it consists of sales records table, joined date lookup table, "daily expenses" table. "daily expenses" table stores single value represents averaged cost of running specific trading location per day. it's extremely easy produce pivottable provides me total sales amount per store per [insert date period]. i'm after dax formulation calculate profit per store per day - ie. total sales minus dailyexpenses (operating cost): in theory, should pretty easy, i'm confused how utilise dax row context. failed attempts: profit:=calculate(sum(salesinformation[saleamount] - dailystoreexpenses[dailyexpense])) profit:=calculate(sum(salesinformation[saleamount] - dailystoreexpenses[dailyexpense]), dailystoreexpenses[storelocation]) profit:=sum(salesinformation[saleamount] - relate

hi im writing code resize dynamically allocated memory. here part of code initializing: int size = 1; string *rev = new string[size]; resizing part: if (j >= size / 2){ size = size * 2; string *temp = rev; rev = new string[size]; memcpy(rev, temp, (size / 2)*sizeof(string)); delete[] temp; // <- here causes error! } when comment out "delete[] temp" code works fine memory leaks. so, how can handle error message "assert". please help! thanks! since pointed out assert caused other parts of code. here full version, print words out in reverse order in given sentence. void reversewords(string &sentence) { char *str = new char[sentence.size()+1]; int size = 1; string *rev = new string[size]; int j = 0; int n = 0; int m = 0; (unsigned int = 0; < sentence.size(); i++){ str[n] = sentence.at(i); n++; if (str[n-1] == ' '){ str[n-1] = '\0'; if (j >= size / 2){

i need capture event instead of letting bubble. want: <body> <div> </div> </body> from sample code have click event bounded on div , body. want body event called first. how go this? use event capturing instead:- $("body").get(0).addeventlistener("click", function(){}, true); check last argument "addeventlistener" default false , in event bubbling mode. if set true work capturing event. for cross browser implementation. var bodyele = $("body").get(0); if(bodyele.addeventlistener){ bodyele.addeventlistener("click", function(){}, true); }else if(bodyele.attachevent){ document.attachevent("onclick", function(){ var event = window.event; }); } ie8 , prior default use event bubbling. attached event on document instead of body, need use event object target object. ie need tricky.

i have user-control uses anguar.js , declares div ng-app somewhere inside. other part of system doesn't use angular.js , doesn't reference it. now, problem after partial update of html (using update-panel, instance) need recompile (because it's injected dom) , cannot technically this, far whole html ng-app declaration being replaced. and not have access $compile service (okay, can using $injector , $scope ?) function afterpartialupdate(containerelement) { var injector = angular.injector(['ng']); injector.invoke(function($compile) { $compile(containerelement)( ???need scope, lost ); }); }; i can store scope @ moment of initial page-load in global variable. recompiling using same scope results in incremental increase of $$watchers collection , other unwanted side-effects... i guess there should way force angular execute same javascript executes during intial page-load, i.e. create modules, traverse html, instantiate controllers

i have html form in need allow numeric key-press. have used following code $(".span8").keypress(function(e) { var unicode=e.charcode? e.charcode : e.keycode //alert(unicode); if ((unicode ==8) || (unicode==9)|| (unicode==46)){ //if key isn't backspace key (which should allow) } else { if (unicode<48||unicode>57&&unicode!=65) //if not number return false //disable key press } }); but here if testing keycode, getting value 46 delete key. 46 dot(- period) others values coming correct. not able find going wrong. please i've found weird behaviour keypress function. instead, try following: jquery(function($) { var input = $('.span8'); input.on('keydown', function() { var key = event.keycode || event.charcode; if(key == 8 || key == 46) //do when del or backspace pressed }); });

i have unordered map string int uses custom equal_to function defined as: bool hashequal::operator ()(const string &a, const string &b) const { if (a.size() != b.size()) return false; return std::inner_product( a.begin(), a.end(), b.begin(), 0, std::plus<unsigned int>(), std::not2(std::equal_to<std::string::value_type>()) ) <= 8; } basically if 2 keys have hamming distance equal or less 8, same key. the thing want distance threshold dynamic in order let user set through command line. instead of 8, variable threshold or this. i'm not looking hack global variable (unless it's way achieve this) "good way". why `unordered_map` doesn't work reliably a general-purpose hash function maps keys buckets in repeatable otherwise seemingly random way, mean if key varies single bit bucket should statistically unrelated - if you'd picked @ random. so, have hash table

i'm using angular js. loop out part of scope start json array. i need check if value in array exists. if should something. following code work can't figure out way save "status" temporary. <div ng-repeat="item_value in item['slug'].values"> {{item_value}} <div ng-if="item_value == 'dogs_cats'"> somehow save "status" true when above equal. </div> </div> <div ng-if="status == 'true'"> someting here. </div> maybe approach wrong. maybe should not go in template? different solutions choose , suggestions on prefered. i think do: <div ng-if="item_value == 'dogs_cats'" ng-init="status = true"> somehow save "status" true when above equal. </div> but preferably should put logic in controller
