i have 1 array multiple dictionary object keys date , type want arrange array in ascending order date key. my array : ( { date = "06 september 2016"; type = photo; }, { date = "06 september 2016"; type = video; }, { date = "07 september 2016"; type = photo; }, { date = "07 september 2016"; type = video; }, { date = "06 september 2016"; type = photo; }, { date = "06 september 2016"; type = photo; }, { date = "07 september 2016"; type = photo; }, { date = "01 october 2016"; type = photo; }, { date = "06 september 2016"; type = photo; } ) please me. how can arrange in ascending order date. you need use sortedarrayusingcomparator way sort date string. first convert date string nsdate using nsdateformatter , compare. nsdateformatter *df = [[nsdateformatter alloc] init]; [df set

i have been working on code return boolean value, happens variable gets overwritten true or false looks row in foreach statements. when pass in view file no value taken/appears. can me why happening , how pass boolean? view file echo testcontroller::showprerequisites(29005); model $validator; foreach($prereq $values){ if(finishedsubjects::find()->where(['subjectname' => $values['col']])->exists()){ $validator = true; } else { $validator = false; } } return $validator; controller public function showprerequisites($trno){ $model = new testmodel(); return $model->showprerequisites($trno); } edit view update $preq = testcontroller::showprerequisites(29005); if($preq = true){ echo 'pre requites completed/read'; } else if($preq = false) { echo 'pre requisites not completed/not read'; } you have logical error in code, assigning value in if condition , checking, return true. ins

in angularjs if invoke service method: app.service('nameservice', function(){ this.service = function (){console.log('hello')} } then can use service (object) : nameservice.service() question how can write function have 2 arguments(name, function) function service ( name, function ){ // how angular declare object value of first argument ? } i'm ask how write function service(name,fn){} ? angularjs use dependency injection inject service. "service" method available on angular object because on prototype. angular.prototype.service = ... you can read more prototype inheritance, mdn - inheritance , prototype chain

i have code , when executes, throws nullreferenceexception , saying: object reference not set instance of object. what mean, , can fix error? what cause? bottom line you trying use null (or nothing in vb.net). means either set null , or never set @ all. like else, null gets passed around. if null in method "a", method "b" passed null to method "a". the rest of article goes more detail , shows mistakes many programmers make can lead nullreferenceexception . more specifically the runtime throwing nullreferenceexception always means same thing: trying use reference, , reference not initialized (or once initialized, no longer initialized). this means reference null , , cannot access members (such methods) through null reference. simplest case: string foo = null; foo.toupper(); this throw nullreferenceexception @ second line because can't call instance method toupper() on string reference pointing null .

i wanted remove characters after end of first number sequence. edit: (sorry ambiguity) the string may or may not start letters, in case starts letters should preserved. after first sequence of numbers, should removed. e.g. qwee1232rty -> qwe1232 123rty -> 123 12342 -> 12342 str.replaceall("[^a-z][^0-9]+",""); this should work it's giving unexpected output , not printing repeated "2". my ideone code attempt , it's respective outputs import java.util.*; import java.lang.*; import java.io.*; class ideone { public static void main (string[] args) throws java.lang.exception { string str = "bctc27452asdfccc"; system.out.println(str.replaceall("[^a-z0-9]","")); // bctc27452asdfccc system.out.println(str.replaceall("[^a-z0-9]$","")); // bctc27452asdfccc sys

i modified basic phantomjs example here http://phantomjs.org/screen-capture.html accept command line args. when pass http://google.com argument console.log outputs correct 0: index.js 1: http://google.com but don't thumbnail.png in folder why ? var page = require('webpage').create(); var system = require('system'); var args = system.args; var url; if (args.length === 1) { url = 'http://github.com/'; } else { args.foreach(function(arg, i) { console.log(i + ': ' + arg); if (i > 0) { page.open(arg, function() { page.render('thumbnail' + '.png'); }); } }); } phantom.exit(); page.open asynchronous function, therefore phantom.exit being called before callback render thumbnail. move phantom.exit inside callback specified in docs var page = require('webpage').create(); page.o

i have: - slicer dates , table 'log' column 'date' dates , column 'max' numbers (e.g. 0,31) i need calculate average of values in column 'max' when date before slicer selection date - , average after. end result: card visualisation average of values before selected date , card visualisation average of values after selected date. create 3 measures: avg = average('log'[max]) averageafterselecteddate = calculate ( [avg], filter ( ( 'log' ), [date] > minx ( 'log', 'log'[date] ) ) ) averagebeforeselecteddate = calculate ( [avg], filter ( ( 'log' ), 'log'[date] < minx ( 'log', [date] ) ) ) just use averagebeforeselecteddate , averageafterselecteddate measures in cards. for data: it produces: let me know if helps.

i've got table containing number of text columns, , need able query table using search term. single terms, simple... select * things @searchterm in (column1, column2...columnx) however, need search on multiple terms in single query, like... select * things @searchterms in (column1, column2...columnx) ...where @searchterms collection of values, rather single value. there way emulate behaviour in sql? update: thank @tedo g., unfortunately need query use and between different terms. i've added change yours group results , ensure count per distinct result matches number of terms... select * things inner join @searchterms b on b.[fieldname] in (column1, column2...columnx) group column1, column2...columnx having count(column1) = @numberofsearchterms ...this works, there better way? one other way achieve make table variable , fill search term values, join : select * things inner join @searchterms b

i'm looking simple way move on next iteration in loop in r if operation inside loop errors. i've recreated simple case below: for(i in c(1, 3)) { test <- try(i+1, silent=true) calc <- if(class(test) %in% 'try-error') {next} else {i+1} print(calc) } this correctly gives me following calc values. [1] 2 [1] 4 however once change vector in include non-numeric value: for(i in c(1, "a", 3)) { test <- try(i+1, silent=true) calc <- if(class(test) %in% 'try-error') {next} else {i+1} print(calc) } this loop doesn't work. hoping same calc values above vector excluding non-numeric value in i. i tried using trycatch following: for(i in c(1, "a", 3)) { calc <- trycatch({i+1}, error = function(e) {next}) print(calc) } however, following error: error in value[[3l]](cond) : no loop break/next, jumping top level could please me understand how achieve using loop in r? as dason noted, atomi

i have code here popular = impression.select('impressionable_id, count(impressionable_id) total').group('impressionable_id').order('total desc').limit(9) @events = event.where(id: popular.map(&:impressionable_id)) however what's happening @ moment @events returning duplicate names. i'm wondering how return them without returning names match. update here's mean, basically @events working fine, can call @events.eventname , 9 different events in view. however, if example charity fun day appears twice (has 2 different ids) wouldn't want event name appear twice in this. @events = event.where(id: popular.map(&:impressionable_id)).uniq will give unique event items. if there events different same names can @events = event.where(id: popular.map(&:impressionable_id)) @events.uniq{|event| event.name }

what need: need editable combobox filters data on popup upon typing , first matching item should highlighted , should set text in combo upon pressing enter. the popup should tableview 2 or 3 columns. (screen shot attached.)(in image textfield prefer combo if user not sure values, can click combo button , see entire list , select one.) i binding data source tableview should act popup combobox. know should go custom control dont know start? reference url: enter link description here thanks in advance. what have tried far: guys, with idea guys gave, have tried far , able achieve. (for now, not showing tableview dynamically below text field (eventually dats wat want)) 1. tableview static data loaded , added scene. 2. having text field below tableview. (this named txt) 3. having text field below first text field(this named txt1) (when press tab previous text field cursor should come here) i have predicate set table , updating predicate user types in txt.

i stumbled on fact indexer this[int index] { get; } works differently array of structs list of structs. namely, indexer in case of t[] returns reference element within array whereas indexer in case of list<t> returns copy of element. this big semantic , performance difference, , i'm glad t[] allows work around performance limitation of list<t> . however, i'm puzzled actual implementation. code array in .net reference sources reads thus: object ilist.this[int index] { { return getvalue(index); } set { setvalue(value, index); } } where getvalue defined follows: public unsafe object getvalue(int index) { if (rank != 1) throw new argumentexception(environment.getresourcestring("arg_need1darray")); contract.endcontractblock(); typedreference elemref = new typedreference(); internalgetreference(&elemref, 1, &index); return typedreference.internaltoobject(&elemref); } the return type of indexe
