i'm write ajax based chat. best way refresh chat box? know there few possibilitys best suited chat? additional: possible reload unread text? if writes text isn't nessecarry refresh whole content.the new message enough. can done ajax , php? have no idea how done. thankfull tipp ... thanks! the frequency of refresh , scope of content refresh independent. ajax, can ask server if new message arrived (based on timestamp), , append displayed content, don't have reload whole page. as 'periodic refresh' thing: can go either short polling or long polling. think 'periodic refresh' may refer short polling. timer, e.g. in every second server polled javascript there new data displayed. if yes, sends it, otherwise replies message indicating there no new content. whilst in long polling, server polled, , gives new content if has it. however, if there no new content, instead of giving immediate answer of 'no new content', keeps connection open, ,

i having markers on map , same number of rows in slickgrid? what want when marker clicked id of marker matched rows , corresponding row should selected. here code: var $canvas = $(grid.getcanvasnode()); var $allrows = $canvas.find('.slick-row'); $($allrows).each(function() { if ($(this).rowid == selectedmarker) { $(this).addclass("active-row"); grid.scrollrowintoview($(this).index()); } }); it works fine when row want present in grid grid dom contains 8 rows @ time (the grid has 30 rows). how can loop through data? you shouldn't modifying slickgrid's dom @ all. slickgrid overwrite changes it's rendering rows in view (with buffer). when scroll past buffer changes made dom lost. you have change row's data , allow slickgrid add appropriate classes dom when it's rendering. edit : slickgrid setup: dataview.getitemmetadata = metadata(dataview.getitemmetadata); function meta

i'm trying match string of url using preg_match need match either 1 or other string , can't find correct syntax. what i'm using is: $is_url_en = preg_match ("/\b95\b/i", $iframeurl); this searches number "95" in url. want match "en" don't know how use 'or' delimiter. i've seen somewhere following: $is_url_en = preg_match ("/\b95\b/i|/\ben\b/i", $iframeurl); ...but doesn't work. hints please? don't repeat / , /i . delimit regex should there once. $is_url_en = preg_match ("/\b95\b|\ben\b/i", $iframeurl); you simplify to: $is_url_en = preg_match ("/\b(95|en)\b/i", $iframeurl);

how compare 2 pointers see if of same type? say have... int * a; char * b; i want know whether or not these 2 pointers differ in type. details: i'm working on lookup table (implemented 2d void pointer array) store pointers structs of various types. want use 1 insert function compares pointer type given types stored in first row of table. if match want add pointer table in column. basically want able store each incoming type own column. alternative methods of accomplishing welcomed. in case, since know types before hand, doesn't make sense check. can proceed knowing different types. however, assuming perhaps types may dependent on compile-time properties template arguments, use std::is_same : std::is_same<decltype(a), decltype(b)>::value this true if same type , false otherwise.

you can "change" key of array element setting new key , removing old: $array[$newkey] = $array[$oldkey]; unset($array[$oldkey]); but move key end of array. is there elegant way change key without changing order?
