there scene in application has 2 labels , menu item. when load scene using replacescene method stays 3-4 seconds , gets disappeared or released. want keep until cancel button pressed. how can it? code is: @implementation mylayer + (id)myscene { ccscene *ascene = [ccscene node]; mylayer *mylayer = [mylayer node]; [ascene addchild:mylayer]; return ascene; } - (id) init { if (self = [super init]) { //labels , menu here } return self; } and calling scene this: [[ccdirector shareddirector] replacescene: [mylayer myscene]]; maybe problem it's first scene. should use runwithscene method of ccdirector .

in local repo have 1 commit incorrect commit message. i've published incorrect commit message git push . now remote repo (which github-hosted) has incorrect commit message, too. i've tried git commit --amend , found not work me in situation because i've made additional commits since incorrect one. how fix situation? easiest solution ( but please read whole answer before doing this ): git rebase -i <hash-of-commit-preceding-the-incorrect-one> in editor opens, change pick reword on line incorrect commit. save file , close editor. the editor open again incorrect commit message. fix it. save file , close editor. git push --force update github. this mean publishing modified version of published repository. if pulled or fetched repo between when made mistake incorrect commit message, , when fixed it, experience difficulties later. sure can accept consequence before trying this.

is capacity size of string multiple value of 15? for example: in cases capacity 15 string s1 = "hello"; string s2 = "hi"; string s3 = "hey"; or random? is capacity size of string multiple value of 15? no; guarantee capacity of std::string s.capacity() >= s.size() . a implementation grow capacity exponentially doubles in size each time reallocation of underlying array required. required std::vector push_back can have amortized constant time complexity, there no such requirement std::string . in addition, std::string implementation can perform small string optimizations strings smaller number of characters stored in std::string object itself, not in dynamically allocated array. useful because many strings short , dynamic allocation can expensive. small string optimization performed if number of bytes required store string smaller number of bytes required store pointers dynamically allocated buffer. whether or not ...

i reading through source of artifice , saw: module artifice net_http = ::net::http # ... end line: https://github.com/wycats/artifice/blob/master/lib/artifice.rb#l6 why not net::http instead of ::net::http , i.e., mean when use :: prefix? the :: scope resolution operator. determines scope module can found under. example: module music module record # perhaps copy of abbey road beatles? end module eighttrack # gloria gaynor, survive! end end module record # adding item database end to access music::record outside of music use music::record . to reference music::record music::eighttrack use record because it's defined in same scope (that of music ). however, access record module responsible interfacing database music::eighttrack can't use record because ruby thinks want music::record . that's when use scope resolution operator prefix, specifying global/main scope: ::record .

(that seems messy) how should identify , access these identical groups of input fields? you can use document.getelementsbyname('name') , loop on result each value.

i know basic stuff need understand whether understanding of correct. so want this. want view label on when double tapped flips , loads view. on second view want uipickerview , above have button saying back. both views of same size uipickerview 320px x 216px. what thinking of create 2 uiview classes named labelview , pickerview. create viewcontroller on loadview loads labelview when user double taps labelview event in labelview class sent viewcontroller can unload loadview , load pickerview . does sound best way ? there simpler way ? unsure how route event labelview class viewcontroller class. i dont know efficient way it(as language),but sure have solved ur problem. made simple program that.three classes involved here in eg baseviewcontroller (which show 2 views),labelview , pickerview (according ur requirement). in labelview.h @protocol labelviewdelegate -(void)didtaptwicelabelview; @end @interface labelview : uiview { id <labelviewdelegate> de...

i want android-powered pad information terminal customers. the thing has to show html5 webpage. therefore, 1. should not posiible show website (only local one), should no problem it should possible leave app password (how?) and buttons should disabled (that´s hard). i found out how set target home button, maybe there existing solution. thanks christian i assume understand easiest way develop android native application show webpage. done using webview , support of html5 depends on platform, if use video or audio, may need hooks. trhough webview, can filter urls can opened or not. and well, don't think there many problems on exiting when password entered. regarding number 2, afaik, can let activity ("window" of application) handle of keys, can't map power key. but have confess, when develop application, find issues... not easy wrote in these lines... luck!

i have 2 static tables 500 records each provide lookup material listviews in app. when app first starts , tables created run process populate tables takes less minute i've been looking run process in background using async task progress dialog letting user know happening. concern while process running , data being added , user tilts phone process cancel. state of database then? async task best solution or should use threading? so when rotate or change orientation of phone, activity thing destroyed. don't have rid of async task. in fact live on. don't let task come in , work on ad-hocly. so if want have activity act if upon rotating can start right up, left off, there method called onretainnonconfigurationinstance(). it's method stashes objects can't parceled in saveinstancestate() so idea being: public void oncreate(bundle a) { ... asynctask mytask = getnonconfigurationinstance(); if (mytask == null) { mytask = new asynctask(); ...

i want disable calendar if there no events day (i'm using on sidebar in basicday view). know how can check number of events can disable calendar if there none? help appreciated! in advance. you can use following callbacks find out if there data in view: var numevents = 0; $("#calendar").fullcalendar({ loading: function(isloading, view) { if(isloading) { // starting fetch events numevents = 0; } else { // done fetching events if(numevents == 0) { // disable calendar } else { // ensure calendar enabled } } }, eventafterrender: function(event, element, view) { numevents++; } }); since fullcalendar loads events current view, figure out view has new data (unless store them on client side), you'll want implement code on server side can return next date event. can use gotodate on calendar go date once server.

sorry unclear title, don't know how state (feel free edit), give example: sqrt(108) ~ 10.39... want sqrt(108)=6*sqrt(3) means expanding 2 numbers so that's algorithm i = floor(sqrt(number)) //just in case, floor returns lowest integer value :) while (i > 0) //in given example number 108 if (number mod (i*i) == 0) first = //in given example first 6 second = number / (i*i) //in given example second 3 = 0 i-- maybe know better algorithm? if matters use php , of course use appropriate syntax there no fast algorithm this. requires find square factors. requires @ least factorizing. but can speed approach quite bit. start, need find prime factors cube root of n, , test whether n perfect square using advice fastest way determine if integer's square root integer . next speed up, work bottom factors up. every time find prime factor, divide n repeatedly...

i'm using imagemagick convert pdf file png (thumbnail) image, , works well. i'm wondering whether it's possible convert pdf, has white background, png file transparent background (i.e. set white pixels transparent). this php code i'm using (which results in png file white background): /* open first page of pdf file */ $im = new imagick($pdf_filepath . '[0]'); /* scale */ $im->thumbnailimage($width, $height); /* convert png */ $im->setimageformat('png'); /* save file */ $result = $im->writeimage($thumbnail_filepath); check out: http://imagemagick.org/usage/channels/#mask_creation i think have create gif first , png if wish.
