unfortunately , i cannot use Server-side controls bcose , the user will enter more than 50 records at a time, and its not so safe to use ajax bcose the network is too low... Plz suggest ...

if you arent using server side code what are you doing with the rows once they are added? i've used ajax and it runs fairly quickly if you do it right, you just have to be more careful with how you write the server code because poorly written code runs slower and with ajax people are more likely to notice.

Hi all,
I am writing a webshop. In the header of the "products" page, I have the following:
<pre>
session_start ();
include "php/init.php";
In the init.php, I fill a numer of session variables with product information like:
if (!isset ($_SESSION['products']))
{
$_SESSION['products'][ 0]['id'] = '1';
$_SESSION['products'][ 0]['name'] = 'Castle Lager';
$_SESSION['products'][ 0]['number'] = 0;
$_SESSION['products'][ 0]['price'] = 1.25;
$_SESSION['products'][ 0]['disp'] = '1,25';
$_SESSION['products'][ 0]['VAT'] = 2;
$_SESSION['products'][ 1]['id'] = '2';
$_SESSION['products'][ 1]['name'] = 'Hunters Dry';
$_SESSION['products'][ 1]['number'] = 0;
$_SESSION['products'][ 1]['price'] = 1.70;
$_SESSION['products'][ 1]['disp'] = '1,70';
$_SESSION['products'][ 1]['VAT'] = 2;
etc...
and in the Products.php page, I use these variabes to fill a product list:
foreach ($_SESSION['products'] as $item)
{
etc....
}
</pre>
The reason that I am filling all the individual items is that I have a PC program that maintains all this information, and automatically generates the init.php file on the server.
My issue is that when I first start the page, everything works just fine. However, when I do a refresh of the page, I get the error message "Invalid argument supplied for foreach". If I test if the $_SESSION['products'] has been set, then it says that is has been set, however, if I test for "is_array ($_SESSION['products'])" then it returns false.
Any ideas on how this can have happened would be greatly appreciated!!!
Regards,
William

i may be wrong but try using "" round the numbers in the second level of the array.
ie: $_SESSION['products']['0']['id'] = '1';
if that doesnt work, try outputting the array on the page by doing this
print_r(_SESSION['products']);
That will show you what you have in the array

Thanks a lot. Meanwhile, I found the real cause of the problem and I am ashamed of myself..... Somewhere hidden in an includefile, I used $_SESSION['products'] for a completely different purpose (shame, shame, blush). I still did not quite figure out how I get there from the code that I mentioned, but when I renamed $_SESSION['products'] to $_SESSION['merchandise'], everything worked as expected!!
Thanks again,
William

If the job sites want you to use their data then they will expose some kind of API. You will be able to find out more details of this from the individual websites.
On the other hand you could use a technique called scraping, but that is likely to be breaking the terms and conditions of the websites.

i recomend looking up the VoiP(voice over IP) or video over IP codecs and standards, they are different, but they do have a few things in common, SIP, RTP, ATM. I cant remember the video stuff off the top of my head but i know voice uses G.711, H.323, g.729 might be useful but icant remember what its for right now( not enough coffee). I'd start googleing that stuff and once you feel you understand it move on to opensource VoIP projects, this stuff is rather time sensitive, unless you dont want decent quailty out of the image or audio. There are also several companies that sell products that probably do what you want, you'll runinto them while researching the standards and protocols.

Hey all.
I want to customize a form's submit. Therefore I'm overwriting the standard submit function using
<br />
HTMLFormElement.prototype.mySubmit = HTMLFormElement.prototype.submit;<br />
HTMLFormElement.prototype.submit = function(eventObject)<br />
{<br />
...<br />
}<br />
Firefox is doing well but IE (version 7 tested) yields " 'HTMLFormElement'is not defined ". What the hell? 
I was straining google and got a few articles reporting the same problem while using frameworks (prototype & script.aculo.us). But I don't use any framework at all.
Has anyone an idea how to get around this?
Thanks in advance!

add overflow:hidden to the td style for clipping.
It won't wrap unless there are spaces though. Sorry.

Hi to all,
I am using ASP.Net 2008. I want to use functions from my js file(s),containing only functions, in .aspx page(s).
My 'Validate.js' file looks like this,
function isValid() {<br />
alert("isValid called");<br />
}
I want to use this isValid() function in my all .aspx files.
So I tried following code in one of my .aspx file,
<script lanaguage="javascript" type="text/javascript" src="Validate.js"><br />
function Validate(){<br />
isValid();<br />
}<br />
</script>
But it is not working. Doesn't show the alert box.
Can anyone suggest solution for this?
I appreciate any and all comments and suggestions.
Regards,

Is the path to the JS file correct? Are you actually calling Validate on your page?
Incidentally, you don't need to specify the language parameter.
