i trying sort array of structs using qsort() frustratingly, it's not working. have read manpage qsort() , think have comparator function syntactically looks okay, when print "sorted" array after calling qsort() , nothing sorted in array. the code: #include <stdlib.h> #include <stdio.h> #define array_sz 5 typedef struct singlechar { unsigned char character; unsigned int weight; } *singlecharptr; int compareweights(const void *a, const void *b) { const singlecharptr p1 = (singlecharptr)a; const singlecharptr p2 = (singlecharptr)b; // printf("weight1: %u\tweight2: %u\n", p1->weight, p2->weight); // return (p1->weight - p2->weight); if (p1->weight < p2->weight) return -1; else if (p1->weight > p2->weight) return 1; else return 0; } singlecharptr makechar(unsigned char c, unsigned int w) { singlecharptr scptr = malloc(sizeof(struct singlechar));

when firefox resized embedded mfc application (which uses apapi plugin embeddation) unable fit in resize window (firefox). till 17.0 version issue not there, post 17.0 issue reproducible. whenever resized wm_paint (message 15 ) send application code flow (pre 18.0 firefox version embedded application): pwnd->windowproc(nmsg, wparam, lparam) cwnd::windowproc ---> if (!onwndmsg(message, wparam, lparam, &lresult)) lresult = defwindowproc(message, wparam, lparam); this in turn calls cview::onpaint() now 18.0, unable call application. let me know further clarification.

seem can't make right. basically, 3 php files used: - login.php, testconnect.php , numrows.php numrows.php main file first start played. login.php , testconnect.php good. numrows.php:- <?php global $dbh1; require_once "testconnect.php"; try { $stmt = $dbh1->prepare("select count(distinct mfg_code) test"); $stmt->execute(); } catch(pdoexception $err) { $alertmsg = $err->getmessage(); } $num = $stmt->fetch("pdo::fetch_assoc:"); $num = json_encode($num); echo $num; ?> the log error apache showed ""get /testnumcards.php http/1.1" 500 -". again error encountered while debugging "networkerror: 500 internal server error". right way do? your problem not in making $dbh available in inconsistent code , wrong syntax. @ least make file way, without useless , wrong code <?php require_once "testconnect.php"; $stmt = $dbh1->prepare("select count(

table structure catalog_product_category_bindings : `productid` integer unsigned not null `categoryid` integer unsigned not null table structure catalog_products : `id` integer unsigned not null auto_increment misc unrelated columns task: data of products not bound category (no entry in catalog_product_category_bindings ). query #1 (using left join): select cp.* catalog_products cp left join catalog_product_category_bindings cpcb on cp.id = cpcb.productid cpcb.categoryid null query #2 (using nested select): select cp.* catalog_products cp id not in (select productid catalog_product_category_bindings) both queries seem quite similar in terms of speed on tables (i don't have in there), believe second 1 worse in performance since loops on every id in catalog_products table , compares every productid catalog_product_category_bindings . not mention might not return , break query altogether (though happen if table truncated). which better? i, personally, pref

i used use following ajax code html element <a class="getcontent" href="/content">...</a> : $('.getcontent').click(function() { var url = $(this).attr('href'); $('#content').load(url); return false; }); if refresh whole page depending on value returned server: $('.getcontent').click(function() { var url = $(this).attr('href'); if (url == "success") { document.location.reload(true); }else{ $('#content').load(url); } return false; }); of course, if part hypothetical. working on google app engine python, server-side script may be: if ...: self.response.out.write('success') else: render(self, 'some_html_file.html') how how do it? thanks. try: var menuid = $("ul.nav").first().attr("id"); var request = $.ajax({ url: url, //your url here type: "post", data: {id : menuid}, datatype: "htm

i'm thinking writing dart based browser game. separate core game logic client render , event handling code. way can run same logic code on server dart vm side in multiplayer system. lots of games doing today (eg. quake series): have local server if play single player game. so in scenario: event handling , rendering runs on main browser thread (render loop triggered requestanimationframe ) game logic runs in separate isolate (actually webworker in browser) for communication i'm using messageboxes bit cumbersome setup , manage it's possible. can later exchanged websocket if logic runs on server. the logic isolate sends messages main thread loop game events (like game object's status being updated, map change, etc.) , main thread posts client side events (key press based player movement, commands) logic. i'm wondering what's best way manage messages on layer. documentation of messagebox: "the content of message can be: primitive values (null

i trying use sinon.js create spy on jquery.append function. i tried: var spy = sinon.spy($, "append"); , got following error: typeerror: attempted wrap undefined property append function . i amended to: var spy = sinon.spy($.fn, "append"); seems better, spy.called false. sinon.spy(object, "method") expects object first parameter, $ function. should spy on $.prototype this: var spy = sinon.spy($.prototype, "append"); fiddle: http://jsfiddle.net/rz825/ or can spy single object this: var spy = sinon.spy($("body"), "append"); fiddle: http://jsfiddle.net/g5j8h/
