i given formula: if not (isnull({person.last_name})) {person.last_name}+","+" "+{person.first_name} else "no name" this formula seems work fine need add field {person.middle_name} when write formula if not (isnull({person.last_name})) {person.last_name}+","+" "+{person.first_name}+","+" "+{person.middle_name} else "no name" if person has middle name, looks fine. if person not have middle name , there no data in field, report shows no information @ all. apologies beginner question, , thank in advance. you can nest additional if statement evaluate middle name. break criteria multiple formulas. create separate formula fname, lname, mname. each have if statement similar above (if isnull({mname} "" else {mname}). then can create additional formula concatenate them {lastname} + {firstname} + {middlename}

i have 2 methods have same code except 2 methods call (and other details can parameterize). however, method calls have same signature, think can generalize them single method. class a{ iapi* m_papi; void m1(); void m2(); public: void dothings(); } void a::m1(){ int i; bool b; m_papi->method1( &i, &b ); //other stuff... } void a::m2(){ int i; bool b; m_papi->method2( &i, &b ); //other stuff... } void a::dothings(){ m1(); m2(); } i can figure out how "parameterize" "other stuff" code, problem calls method1 , method2 . think have use std::bind somehow, can't this... void a::m( std::function<void(int*,bool*)> f ){ int i; bool b; f( &i, &b ); } void a::dothings(){ m( std::bind( ???, m_papi ) ); //m1 m( std::bind( ???, m_papi ) ); //m2 } the problem here m_papi not concrete class (it's interface implemented bunch of concret

i using nest client against elasticsearch. using n-gram index analyzer. noticing odd behavior - when search words beginning not getting results. however, if search second character on, works perfectly. these normal english letters. so, instance, find words containing 'kitty' if search 'itty', 'itt', 'tty', etc. not 'ki', 'kit', etc. it's n-gram skipping on first character. i not sure if being caused nest or if normal behavior n-gram. index settings similar found in post: elasticsearch using nest: how configure analyzers find partial words? except max-gram 10. update i simplified code little bit , verified same behavior. here mapping configuration defined using nest: const string index = "myapp"; const string type = "account"; const string indexanalyzer = "custom_ngram_analyser"; const string searchanalyzer = "standard"; const string tokenizer = "custom_ngram_tokenizer"

i'm using lawndart library access browser data, , want collect results of set of queries. here's thought should work: numberofrecordspersection(callback) { var map = new map(); db_sections.keys().foreach((_key) { db_sections.getbykey(_key).then((map _section) { int count = _section.length; map[_key] = count; }); }).then(callback(map)); } however, when callback called, map still empty (it gets populated correctly, later, after futures have completed). assume problem futures created getbykey() calls not "captured by" futures created foreach() calls. how can correct code capture result correctly? the code how do jquery pattern in dart? looks similar yours for each entry of _db.keys() future added array , waited of them being finished future.wait() not sure if code works (see comments on answer on linked question) void fna() { fnb().then((_) { // here, keys should have been loaded }

using c++, if have n integers in std::map , possible efficiently search largest element smaller k in std::map ? for example have {1, 3, 5, 6} , k 4 returned value should 3 i know std::map can search in log(n) , if exact match. use lower_bound , decrement returned iterator one.

is bad practice write setters booleans check if set correctly? for example, following code set whether frame on top , return true if set decided. bad practice this, or should leave no return type? public boolean setalwaysontop(boolean alwaysontop) { frame.setalwaysontop(alwaysontop); return frame.isalwaysontop() == alwaysontop; } bear in mind in example have getter when want check value when not attempting set it: public boolean isalwaysontop() { return frame.isalwaysontop(); } thanks in advance. if more information please feel free ask , provide it. edit: it's wondering if useful because if(setalwaysontop(true)) instead of using void this: setalwaysontop(true); adding of additional conditions check api work not idea in general. frame.setalwaysontop must work. if don't trust api - cover unit tests. if tests fail should think work around solution - find working version of software, report bug or fix issue

i came across question wanted add active link clicked menu item. the solution add: $("a").click(function(){ $("a").removeclass("active"); $(this).addclass("active"); }); now how can remove active class if click active link second time? i'm guessing need use toggleclass() haven't been able make work. note 1 link should have active class @ time. here demo: http://jsfiddle.net/a6dqq/ you can do: $('a').click(function(e){ e.preventdefault(); var $a = $(this); $a.toggleclass('active').siblings().removeclass('active'); });

i have been lately trying describe given rdb(relational database) specific semantic ontologies, using virtuoso. ontologies want use are: dc,foaf,dct,bibo,cito(i new didnt quite understand if dc , dct same thing). have been following tutorial on how this: http://virtuoso.openlinksw.com/whitepapers/relational%20rdf%20views%20mapping.html problem in tutorial classes created 0 while need use existing ones. unfortunately not allowed post links of ontologies too. in particular want describe: an "author" table(a published paper author) has following columns: authorid, authorname, authormiddlename, authorsurname, authorurl, authoremail, department a "keywords" table(publication's keywords) columns: publicationid, keyword(type of string), keywordorder(type of integer), a "publications" table columns: publicationid, publicationtitle, mediatype(type of string), publicationtype(integer), mediatitle, mediapublisher, mediaeditors, mediavolinfo, p

this question has answer here: will using new (std::nothrow) mask exceptions thrown constructor? 3 answers nothrow constant: constant value used argument operator new , operator new[] indicate these functions shall not throw exception on failure, return null pointer instead. but here in simple example, instead of returning null, new throws exception: struct somestruct { somestruct() { std::bad_alloc exception; throw exception; } }; int _tmain(int argc, _tchar* argv[]) { somestruct* somestruct; somestruct = new (std::nothrow) somestruct; return 0; } any explanation please? indicates, despite having (std::nothrow) parameter new still need put code in try...catch block. std::nothrow means instead of std::bad_alloc being thrown on failure acquire memory, new expre

i'm @ loss here. i've got report multiselect parameters, , works, can't figure out why of parameters show selected values , don't. take following example: parameters dropdowns: notice par1 shows selected values "00400", "00540", etc in dropdown, par2 doesn't show anything, though items selected. both parameters properties pretty identical different queries. i've used same dataset available values , default values, each dataset doesn't return nulls. else can check? users confused i'm sure. thanks!

i want convert rgb values hsv values . if devide 9 28, octave calculate 0. can explain me reason?? function [hsv] = rgbtohsv() im = imread('picture.png'); r = im(:,:,1); g = im(:,:,2); b = im(:,:,3); len = length(r); % r, g, b should have same length = 1:len max = max([r(i),g(i),b(i)]); min = min([r(i),g(i),b(i)]); s = 0; if max == min h = 0; elseif max == r(i) disp(g(i) - b(i)); % 9 disp(max - min); % 28 h = 0.6 * ( 0 + ( (g(i) - b(i)) / max - min) ); % 0 disp(h) % why 0 if try calculate ( 0 + ( (g(i) - b(i)) / max - min)? .... end return; end endfunction rgbtohsv() chris :d you must cast image double doing: im = double(imread('picture.png')); this solve issues happens since image type uint8 .
