I doubt you can do that. You CAN get a variety of info about the machine, at least you can get it from jscript, that's what those sites do when they show you your IP and your machine type, to try and scare you into buying 'security' software.

Hi i have 6 drop downlist in the order of 6 rows. each dropdown is filled with a value ranging from 1 to 3. which represents their preference. I have created three columns in database and names 1st, 2nd and 3rd preference. now how will i be able to get users first second and third preference.
user can select only 3 preference from 6 rows.
example below
1. dropdown1 Apple
2. dropdown2 Orange
3. dropdown3 Banana
...
...
...
please help.

You must store the "ID" of the dropdown in database.
If you dropdowns are named DD_apple, DD_orange, DD_banana, ... and the prefs from user are 2,1,3 you store in DB:
pref1 = "DD_orange", pref2 = "DD_apple", pref3 = "DD_banana".
But I prefer an other solution. I would create 3 columns (for Pref1-3). In each column you have a dropdown with values "apple", "orange", "banana", ... and you store the value from the combo1-3 in you 3 attributes in database. This solution is better extensible in future for more values and/or prefs.
Best regards
Stephan

I know thats the way i should store the data in database but my problem is how will i know which dd was selected 1 so that i could store in column of first preference and so forth for 2nd pref and 3rd pref.
it looks like there will be lots of if and else block do you have any idea how can i strip out the correct dropdown with 1,2,3 ?
please help

Hm.
At first a question. Do you have think over my second solution (3 Columns for the 3 Prefs)? That solves really all problems and questions but it is a little redesign of code, struct and database.
Second: Normally you MUST HAVE 4 entries in the combobox (0,1,2,3) or ('','1','2','3'). Otherwise the user can not deselect a preference and the 0 ('') should be the default selection. Now you can get Combobox.SelectedIndex. This is direct the preference the user choice.
Additional Idea. Write a JavaScript for onChange in the combo (I think you should have this to validate, that user choice only 3 of the 6). In this JS-Func prepare the value of a hidden input element and store there the pref order of combo. Example: User select (6 combos): 0,0,2,1,0,3 -> value of hidden element should be: 4,3,6. Do you understand ?
Another additional idea. JS-Func for onChange in the combo but 3 hidden elements HD_pref1, HD_pref2 and HD_pref3.
function setPref2Hidden (obj, comboindex) {
var val = obj.value;
if (0 != val) {
document.getElementById ("HD_pref" + val).value = combo_index;
}
}
Use it as (Note: CP replace the onChange-keyword below throug "removed" :->:
<select id="DD_pref1" onChange="setPref2Hidden(this,1)" ...>
yselect id="DD_pref2" onChange="setPref2Hidden(this,2)" ...>
<select id="DD_pref3" onChange="setPref2Hidden(this,3)" ...>
...
In CodeBehind store the content of the 3 Hiddens in Database.

Hey All,
I'm having a bit of a problem with loading some images using javascript. What I'm trying to do is parse out a query string value, and load an image using that value.
For instance, if someone went to:
http://www.mydomain.com?person=JohnDoe
It would parse out the name from the query string and load JohnDoe.gif into a image named portrait and write a cookie with that information; if there were no query string value, it would would load a default image. Now, this works in Firefox, but not IE; IE just results in that irritating little red "X" broken image box.
My Javascript:
========================
//get name from GET string
function GetName(CookieKey)
{
//try to read the key "name" value from cookie
var personalimg = readCookie('name')
if (personalimg) //if the cookie exists, load the image with the same name
{
//this appears to be the part that isn't working in IE only (firefox is fine)
//I have checked the image paths and the files do exist
document.contact.src="./images/people/" + personalimg + "Contact.gif";
}
else // if no cookie, check for name in query string or load default image
{
var query = window.location.search.substring(1);
var pair = query.split("=");
//if the cookie contains the key name, load it's value into the image
if (pair[0] == CookieKey)
{
document.contact.src="./images/people/" + pair[1] + "Contact.gif";
document.cookie = "name=" + pair[1] + ";"
}
else //load default image
{
document.contact.src = "./images/Contact.gif";
}
}
}
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
==================
My HTML:
==================
<img src="javascript:GetName('name')" name="contact" />
Note that I don't use Javascript too often so any suggestions on how to improve this would be much appreciated, as is any other help.
Thanks in advance!

how to invisable a row or a cell in a table using java script according the change of radio button?

You can hide a row through javascript like this:
document.getElementById('row0').style.dispay = 'none';
Best Regards,

You can hide a row the way that Apurva Kaushal suggested, but it's not advisable. Tables doesn't work very well with the display property. And hiding cells in a row can have quite unexpected results.

Hi!
It is very simple to detect popup blocer. Examine my code below please.
function detectPopupBlocker()
{
var myTest = window.open("about:blank","","directories=no,height=100,width=100,menubar=no,resizable=no,scrollbars=no,status=no,titlebar=no,top=0,location=no");
if (!myTest)
{
alert("Please allow pop ups for this web site!");
}
else
{
myTest.close();
return;
}
}

No, I can't. There is no such code.
The auto save option is a function in the browser. It's up to the user to decide to use the function or not.

You don't have to remove stored data... you can try to change the name of fields in the form, or form name.
for example, create session and add first 3 characters from session id to the fields in form
session_id = afse422aa32321s // for example
<form name="formname_afs">
<input type="text" name="login_afs" />
... and so on
</form>

Suppose now I have a webpage with following content.
How are you?
Question about calling SAPI from javascript. I came across a difficult problem. Could anybody help me? Thanks!
How do you do?
And I use the following script to interact with the speech engine.
var VoiceObj = new ActiveXObject("Sapi.SpVoice");
VoiceObj.Speak(p2.innerText, SPF_ASYNC); //SPF_ASYNC == 2
What I want is to highlight the word which is currently being read by the speech engine. So it's a synchronization problem.
I think I have to handle the Word event of the SpVoice object. So I wrote the following signature. But what code shall I put in this function?
function VoiceObj::Word(Number, Position, CharacterPosition,Length)
{
}
Very thanks!
