How to deal which large data in ASP.net?,

omyfish — Fri, 06 Nov 2009 17:34:19 +0800

I got a usercontrol which contains a gridview. The usercontrol act as dropdownlist with multicolumn where I using AJAX to make it only appear when user focus on textbox.
I have reuse the control about 2~10 times each pages of my website.
Some of them contain up to 4k> rows of data, and the system took very very long time on every postback. This mainly because of the huge viewstate stored behind the page.

Problem is I can't have paging for the usercontrol dropdownlist.

Is there any method to deal with this kind of situation?

[Need help] adobe director + smartfoxserver, need help about director and sfs

Silolo — Thu, 05 Nov 2009 13:35:20 +0800

Hi,

i need some help regarding using smartfoxserver(sfs) with adobe director. So far, i managed to use the API (smartfoxserver) with director. But the problem is when the file is played, it becomes so heavy. I dont think there's something wrong with the script because for a moment, we can see other ppl (well, that's the point of multiuser) but then after that, the browser or director or application (whatever platform we use to play the file) will becomes not responding. So i can't find where's the fault. Can someone with experience help

or is there any trick to make it alot lighter.. (i think because it's very heavy - i mean the heavy traffic between the sfs and director)

thnx alot..

Insert new element using javascript,

mumeichan — Thu, 05 Nov 2009 13:21:02 +0800

I am writing a Greasemoneky script and I want to insert some form elements after the <body>blablabla<body> part of the page.

What is the general way of inserting new elements using javascript or jQuery with Greasemonkey?

I've read a book on Javascript and also follow some examples online but it doesn't seem to be working too well.

This is the code I used to create a new button

CODE

// ==UserScript==
// @name NewButton
// @namespace None
// @description Newbutton
// @include http://www.epicmafia.com/game/index/*
// @require http://code.jquery.com/jquery-latest.min.js
// ==/UserScript==

window.onload = function createButton() {

var myButton = document.createElement('input');

var id = document.createAttribute('id');
var type = document.createAttribute('value');

myButton.setAttribute('id', 'submit');
myButton.setAttribute('value', 'Submit');

document.appendChild(myButton);
}

help.. Any Event Scheduler in phpMyAdmin?,

pu8y — Wed, 04 Nov 2009 19:29:24 +0800

Hi all,

I am a new user for phpMyAdmin.

Before that, I created my database in my own pc using SQLyog. I also created an event scheduler so that it can delete records which are older than 60 days automatically.

Now, i backup the whole database as sql dump and import into phpMyAdmin. However, I cant find where is that event scheduler was located.

I tried to run a query: SET GLOBAL eventscheduler = ON; but the system returns me:
#1193 - Unknown system variable 'eventscheduler'

I tried to run the query to create an event as below:

CODE

DELIMITER $$

CREATE EVENT `delete_60days` ON SCHEDULE EVERY 1 DAY STARTS '2009-10-28 00:00:00' ON COMPLETION NOT PRESERVE ENABLE DO BEGIN
DELETE FROM properties WHERE DATEDIFF(NOW(), datePosted) > 60;
END$$

DELIMITER;

It also returns me:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'EVENT delete_60days ON SCHEDULE EVERY 1 DAY STARTS '2009-10-28 00:00:00' ON CO' at line 1

I checked in the Server variables and settings for my database in phpMyAdmin, there are no "event scheduler" in the list.

May I know how can I solve this problem?

Thanks in advance.

Problem with PHP in XML files.,

JusticeDeserves — Wed, 04 Nov 2009 02:15:13 +0800

I've added

CODE

AddType application/x-httpd-php .xml

into my .htaccess file

and
[CODE]<? header('Content-type: text/xml'); ?>[CODE]
to the top of my XML file which I want to add PHP support to.

When I visit it using XAMPP, it works fine, it shows the latest feed but when I try it out with Mozilla and IE and Chrome, it downloads the file, and in the file, it contains all my php codes, so why is this happening i would like to ask to all the experts

thanks in advanced
