is there way of presenting on screen @ same time when document, dom, images, ajax's calls, objects , other stuff finished loading? that instead of showing them "in-parts" browser gets information server. any solution useful. set display:none; until jquery ajax success() method fires, can set display properties normal. also, make sure ajax code inside of window.onload or $(window).on('load') handler. the downside of if ajax call unsuccessful, page not display, should define ajax error() method in jquery. edit: for showing images when done loading (put outside onload): $('img').each(function() { $(this).css('display','none'); $(this).on('load',function(){$(this).css('display','');}); }); also, want display type of loading symbol improve user experience.

i'll try explain problem: i have 1 model attorney have many rows. every attorney have date expire in date coloumn. ex: 15/09/2013 i need check, every day, if attorney expire in 30 days. in other words, need check, every day, date of every attorney registered , if date of expire less 30 days, , grab id of attorney in situation , execute action. i have nothing. how this? you need use cron job execute these task every day. to check if record expire in 30 days, use php strtotime calc final date. then, should compare if expire date lower or equals: date('y-m-d', strtotime( date('y-m-d') .

(i not changing code, re-deploying). the problem is: after clients have reconnected, of them not able receive messages sent them, receive broadcasts. here hub code: public class chathub : hub { private string getroleid() { return roleenvironment.currentroleinstance.id; } public override task onconnected() { string message = string.format("onconnected ({0}) {1} - version: {2}", getroleid(), context.connectionid, system.reflection.assembly.getexecutingassembly().getname().version); clients.all.newmessage(message); ...

general problem have often: want perform operation on data.frame, each factor level produce 1 number, , uses information multiple columns. how write in r? i considered these functions: tapply - doesn't operate on multiple columns aggregate - function given columns separately ave - result has same number of rows input, not number of factors' levels by - hottest candidate, i hate format returned - list. want data.frame result, know can convert ugly, prefer solution! the op asking general answer, think 'plyr' package appropriate. 'plyr' package has limitations when approaching large data sets, everyday use (implied in original post), 'plyr' functions wonderful assets r user. setup : here quick data sample work with. data <- data.frame(id=1:50, group=sample(letters[1:3], 50, rep=true), x_value=sample(1:500, 50), y_value=sample(2:5, 50, rep=true)*100) how use plyr : i'm going address basic uses here example things started....
