i'm trying add newly created partial existing list of partials gets rendered in create.js.erb controller action response, , nice scroll item , indicate new addition highlighting or something. have gotten hang of scrolling part in client side javascript, effects come after partial render in create.js.erb don't run. there plenty of examples of being possible, i'm not sure why mine doesn't work. first try: create.js.erb $('#alltab').removeclass('active'); $('#activetab').addclass('active'); $('#completetab').removeclass('active'); // todo: make sure li below gets id="campaign_####" before render happens. $('#activetablist').append("<li><%= escape_javascript(render partial: 'fundraisers/fundraiser', locals: {f: @fundraiser, g: @group}) %></li>") var number_li = $('#activetablist li').length; var $newcampaigndiv = $('#activetablist li').last().chi

i have simple query running against mongo using official c# driver 1.8 returns performing query 50% of time. have unit test , if run query return 50% of time in less second other times never finish. below query var q = database.getcollection<stuff>("stuff").asqueryable() .where(x => x.partition == partitionname && x.persistantid != null && ( (x.when.datestart > startingfrom && x.when.dateend == null) || (x.when.dateend > startingfrom))); return q.tolist(); when take query , run in mongovue using query below can response in under 1 second. { "partition" : "partitionid:53", "persistantid" : { "$ne" : null }, "$or" : [{ "when.datestart" : { "$gt" : isodate("2012-04-01t06:00:00z") }, "when.dateend" : null }, { "when.dateend" : { "$gt" : isodate("2012-04-01t06:00:00z") } }] } it seems perha

i'm working on project structure similar following: root/inc/foo/bar/ root/src i've started use google protocol buffers , when compile code found need add foo/bar/file.h file.cc file in order code find header. don't plan commit .h , .cc files repo since automatically generated. there parameter can give protoc seperate header/source files different directories , add correct path source file #includes? maybe append script "mv foo.h foofolder/" after executing protoc

i have app , utilizing routes load 2 different views. the first route #/ main list view. works every time. my second route #/view/:id , loads second view when list item clicked. the view data driven based off id, of need make $http requests through service created. is possible when leave #/view/:id route, unloads view , reloads when come back? or how go resetting promises inside service next time view loaded, request new data? these not mutually exclusive questions. routing ngview destroys view, scope, , controller on every load, controller , scope history not preserved among routes. otherwise, memory load in browser high; instead, can use services preserve state need across routes. $http requests made fresh every time called, unless cache option enabled. there shouldn't work required work designed: .factory( 'dataservice', function( $http ) { return function dataservicefn ( id ) { return $http.get( '/myapi', { params: { i

i'm still relatively new java. i've been working on program display mandelbrot set. current code generates image close, not quite mandelbrot set. generation code: private void generatemap () { // scale, iterations, map, , size class variables // cr , ci actual coordinates in set being used double cr = -2*scale; double ci = -2*scale; // , b step through array used store drawing // , control when loop exits (int = 0; < size.width; a++) { (int b = 0; b < size.height; b++) { double xr = 0; double xi = 0; int iter = 0; while (iter < iterations) { xr = (xr*xr-xi*xi) + cr; xi = (2*xr*xi) + ci; if (xr*xr+xi*xi > 4) { map[a][b] = iter; iter = iterations; } iter++; } ci += increment*scale; } ci = -2*s

i'm trying develop application allows managing of users via winforms , sql server ce database. i've established way users login via login set in table database username , password columns. now, i'm trying figure out best way go limit access specific features of application. goal sort application modules (customers, employees, billing, etc.) , give user read write permissions entire module. later on might try implement security on per-form basis. any ideas on how accomplish this? first need create roles table on sql ce. so usertable might have roleid fk added in each user. let have admin , user role. in each of form, add security handler methods / class checks role of user access application. create public string role; , puclic string username in each of form can pass values rest of form. example on customer form load can add if(role=="admin") { //visible controls stuff } else { //user //set controls read stuff } on log

i have document mailmerge fields, not want use whole datasource->mailmerge idea. instead presenting userform on autonew() , asking user type data fields. the reason because document "merged" 1 row of data waste of time asking user whole data source thing 1 row. i have working solution using docvariables i'm sure people correct way it, client likes idea of "seeing" mailmerge variable (such <<1>>) in source document. know can use alt-f9 display codes see docvariables, insist on wanting use mergefields. using docvariables using following. works know have right idea , rest of code works fine. activedocument.variables("varsurame").value = .txtsurname however, cannot workout how same thing merge fields. want below (but there no "value" property set). activedocument.mailmerge.fields("surname").value = .txtsurname the .text property readonly cannot use that. the following renders "bookmark not defined

i created 2 classes, branch , account , want branch class have array of account pointers, fail it. says "incomplete type not allowed". wrong code? #include <string> #include "account.h" using namespace std; class branch{ /*--------------------public variables--------------*/ public: branch(int id, string name); branch(branch &br); ~branch(); account* ownedaccounts[]; // error @ line string getname(); int getid(); int numberofbranches; /*--------------------public variables--------------*/ /*--------------------private variables--------------*/ private: int branchid; string branchname; /*--------------------private variables--------------*/ }; although can create array of pointers forward-declared classes, cannot create array unknown size. if want create array @ runtime, make pointer pointer (which of course allowed): account **o

i found native layer of android uses class , struct. for example, mediaplayer , stagefrightplayer , audioplayer , metadata class. awesomeplayer , mediasource struct. although read class , struct similar in use, wonder why awesomeplayer created struct. there reason or developer's taste? you try mention awesomeplayer , mediasource android apis? no, aren't, converted structures c++; not belong android libraries! please see diagram of stagefright , lib c/c++ core. android linux core, , can bring c/c++ utils, libs it. reference: http://pierrchen.blogspot.sg/2012/03/share-with-you-what-have-learned-about.html

i'd store simple state (key-value pairs) that's shared across elasticsearch cluster, plugin. (n.b. -- plugin not vehicle/method store state, want use such state in plugin.) i've tried doing via cluster update settings api, settings newsettings = immutablesettings.settingsbuilder() .put(my_setting, my_value).build(); client.admin().cluster().prepareupdatesettings() .settransientsettings(newsettings).execute().actionget(); but, unfortunately, won't work because my_setting not registered in indexdynamicsettingsmodule . can't figure out how hook module (possibly adddynamicsetting method). is there way store custom key-values in transient cluster settings ? (c.f. http api ). as alternatives , seems node state api can return custom values, more things 1 compute , return plugin, rather stored state. storing values in static variables, , distributing throughout cluster broadcast actions option, i'd prefer simple if exists. any solution needs reason

i updating innerhtml of element through ajax succesfully... when want same innerhtml of element using .htm() , not updated innerhtml... it returns previous mark when document loaded..... how solve this..? instead of using html() try using inner html directly. i.e. instead of var youobj = $(".someselector"); var html = yourobj.html(); do: var youobj = $(".someselector"); var html = yourobj[0].innerhtml; although admittedly both should give same result.

objectives imagine that, have matrix like a11 a12 a13 a21 a22 a23 a31 a32 a33 what want is, textbox value rotate matrix that, example if write 2 , press rotate , program must keep both diagonal values of matrix (in case a11, a22, a33, a13, a31) , rotate 2 times clockwise other values. result must like a11 a32 a13 a23 a22 a21 a31 a12 a33 it must work n x n size matrices, , see every 4 rotation takes matrix default state. what i've done so idea that, have 2 forms. first takes size of matrix (1 value, example if it's 5, generates 5x5 matrix). when press ok generates second forms textbox matrix that form 1 code private void button1_click(object sender, eventargs e) { int matrixsize; matrixsize = int.parse(textbox1.text); form2 form2 = new form2(matrixsize); form2.width = matrixsize * 50 + 100; form2.height = matrixsize *60 + 200; form2.show(); //this.hide(); } form 2 code gener
