possible duplicate: nul terminating int array i'm trying print out elements in array: int numbers[100] = {10, 9, 0, 3, 4}; printarray(numbers); using function: void printarray(int array[]) { int i=0; while(array[i]!='\0') { printf("%d ", array[i]); i++; } printf("\n"); } the problem of course c doesn't differentiate between 0 element in array , end of array, after it's 0 (also notated \0). i'm aware there's no difference grammatically between 0 , \0 looking way or hack achieve this: 10 9 0 3 4 instead of this 10 9 the array this: {0, 0, 0, 0} of course output still needs 0 0 0 0. any ideas? don't terminate array value in array. you need find unique terminator. since didn't indicate negative numbers in array, recommend terminating -1 : int numbers[100] = {10, 9, 0, 3, 4, -1}; if doesn't work, consider: int_max , or int_min . as last resor...

i have app uses auth component. logedin members can alter data long have no validation rules in users model. when add array $validate in model logedin users cannot submit data database. i use 1 mysql table named users. in other words works don't have validation in signup view <?php class user extends appmodel { var $name = 'user'; ?> but when add validation this: <?php class user extends appmodel { var $name = 'user'; var $validate = array( 'email' => array( 'email' => array('rule' => 'email','required'=>true,'message' => 'enter proper mail') ) ); } ?> validation in signup view works users in secret area cannot enter data database. my guess is: happening because have set required true . this enforces rule when submitted data of user model, email key needs set. therefore, works in sign form has email key. on other hand, form you're using in se...

it easy understand concept of setter/getter simple data, nsinteger example. if say: nsinteger a; the setter "a" changes value of a, , getter gets (returns) value. easy understand atomic/nonantomic concept since atomic guarantee reading "a" when being chnaged return whole value (getter , setter synchronized). but not understand setter , getter properties pointers objects (nsdata*, nsstring* example). let's example nsmutabledata: if say: nsmutabledata *m_my_mutable; imagine have setter setmymutable , getmymutable property belongs object myobject. if this, call getter (since object before appending data): [[myobject getmymutable] appenddata....] but appendingdata modify it, sould not seen setter action instead ? or setter refer fact of initiliazing value (which can retained example). there must missing in concept. thanks apple92 a setter sets value of property. when set integer property, new integer value stored. when set object prope...

does jquery mobile framework have way of centering elements, buttons? looks defaults left-aligning , can't find way (within framework) this. jquery mobile doesn't seem have css class center elements (i searched through css). but can write own additional css. try creating own: .center-button{ margin: 0 auto; } example html: <div data-role="button" class="center-button">button text</div> and see happens. might need set text-align center in wrapping tag, might work better: .center-wrapper{ text-align: center; } .center-wrapper * { margin: 0 auto; } example html: <div class="center-wrapper"> <div data-role="button">button text</div> </div>

here's i'm doing: $daterange = array('2010-01-01', '2010-01-02', '2010-01-03', ...); $data = array('2010-01-01' => 5, '2010-01-03' => 7); foreach ($daterange $date) { $values[$date] = $data[$date]; } $values results in: array ( '2010-01-01' => 5 '2010-01-02' => null '2010-01-03' => 7 ... ) seems efficient, wonder if there's simple php function that'll handle this. $values = array_merge(array_fill_keys($daterange, null), $data); whether that's more efficient can found out through testing, i'd it's more concise, easy understand, , it doesn't throw errors non-existent keys in $data . :)

my java gui application needs show text end-user, joptionpane utility methods seem fit. moreover, text must selectable (for copy-and-paste) , long (~100 words) must fit nicely window (no text off screen); ideally should displayed @ once user can read without needing interact, scrollbars undesirable. i thought putting text jtextarea , using message in joptionpane.showmessagedialog easy appears truncate text! public static void main(string[] args) { jtextarea textarea = new jtextarea(); textarea.settext(gettext()); // string of ~100 words "lorem ipsum...\nfin." textarea.setcolumns(50); textarea.setopaque(false); textarea.seteditable(false); textarea.setlinewrap(true); textarea.setwrapstyleword(true); joptionpane.showmessagedialog(null, textarea, "truncated!", joptionpane.warning_message); } how can text fit entirely option pane without scrollbars , selectable copy/paste? import java.awt.*; import javax.swing.*; public class te...

i'm trying java build fail when have class overrides superclass method without specifying @override annotation. the build being done via ant, , i've added following elements <javac> task: <compilerarg value="-werror"/> <compilerarg value="-xlint:unchecked,overrides"/> the unchecked option being followed, overrides option being ignored. tried separating 2 xlint options 2 separate <compilerarg> elements, no avail. misunderstanding option does? one note: jdk6 on macosx (10.6). running osx-specific bug? i believe misunderstanding xlint:overrides behaviour. to knowledge, enabling check cause compiler emit warnings (or maybe errors) when encounters method annotated @override not override superclass method. not, however, check overridden methods annotated correctly. edit: tested it. compiler emit error when specify @override on method not override superclass method, or without xlint option. the document...

i'm developing jquery, i'm beginner it's little bit bloated , not elegant. basically, want cookie value nullified when either 1 of 2 forms submitted or submit buttons clicked. don't know how consolidate conditions of function have write out function once, best can this: $('form#searchform-basic').submit(function() { $.cookie('tab_cookie', null); }); $('form#searchform-basic a.search').click(function() { $.cookie('tab_cookie', null); }); $('form#searchform-advanced').submit(function() { $.cookie('tab_cookie', null); }); $('form#searchform-advanced input#search-button-submit').click(function() { $.cookie('tab_cookie', null); }); there's got better way, right? and before asks, yes, think you'd need know when forms being submitted. leaving out click events means function doesn't run when submit buttons clicked. don't know why that, is. give function name, so: ...

i have custom qgraphicsitem implementation. need able limit item can moved - i,e. restrict area. when checked qt documentation suggested: qvariant component::itemchange(graphicsitemchange change, const qvariant &value) { if (change == itempositionchange && scene()) { // value new position. qpointf newpos = value.topointf(); qrectf rect = scene()->scenerect(); if (!rect.contains(newpos)) { // keep item inside scene rect. newpos.setx(qmin(rect.right(), qmax(newpos.x(), rect.left()))); newpos.sety(qmin(rect.bottom(), qmax(newpos.y(), rect.top()))); return newpos; } } return qgraphicsitem::itemchange(change, value); } so basically, check position passed itemchange, , if don't it, change , return new value. seems simple enough, except doesn't work. when checked call stack see itemchange being called qgraphicsitem::setpos, doesn't @ return...

here's want accomplish: {exp:plugin1:method arg="{exp:plugin2:method}"} i’ve tried number of different approaches. approach 1: {exp:plugin1:method arg="{exp:plugin2:method}"} result: plugin1->method ’s arg parameter value string, {exp:plugin2:method} , , it’s never parsed. approach 2: my understanding of parsing order suggests might have different results, apparently not. {preload_replace:replaced="{exp:plugin2:method}"} {exp:plugin1:method arg="{replaced}"} result: arg parameter has same value approach 1. approach 3: first define snippet ( snip ), content is: {exp:plugin2:method} then in template: {exp:plugin1:method arg="{snip}"} result: same approaches 1 , 2. approach 4: noting plugins processed in order appear, have tested placing instance of {exp:plugin2:method} before {exp:plugin1:method} call. thinking wrap first call in regex replacement plugin in order suppress output, trigger...

function append_url( $link, $sort ) { $sort = $_get['sort']; if ( isset($sort) ) { $link = add_query_arg( 'sort', $sort, $link ); } return $link; } i notice undefined index: sort when no sort parameter exists. best way check if sort param exists before creating $ sort variable? $sort = array_key_exists('sort', $_get) ? $_get['sort'] : null; also, if you're setting $sort value $_get, why pass in argument function? seems redundant.
