Let me know what exactly you want to do?
I think you need onload rather than onchange or what you want.
There is no onchange event for Body tag according to W3C Standards.

What you expect this piece of code to do? Please refrain your question.

I think this is not good. Dont use Content-Type to determine the type of the response. I think it is better if you explicitely define a key for content type the client wants.
http:
See I used type key to get JSON response from the client, so the client which uses it have proper knowledge about what type of response it expects.
ArunkGeorge wrote: Should I use xml serialized date or Json serialzied date?
Yes, if you are creating JSON response, Use JSON serialized date, otherwise XML. (I guess it automatically does that way)
ArunkGeorge wrote: Question 2: Most of the deserialization APIs exposed (at least the ones I have seen) deserialize a stream, and not a single datetime value. Do I have to always wrap the datetime into a stream in order to get that deserialized?
Yes I think you are right, But you can create your own Serializer any time and use it.
ArunkGeorge wrote: Is there any easy way to get the query string parameter key-value pairs directly deserialized into a desired object?
Yes, I think there is. You might use Request.QueryString.AllKeys
ArunkGeorge wrote: Question XmlSerializer accepts only a child of ICollection and so I am not able to pass a HashTable etc.
Yes... HashTables are different than normal, you can pass hashtable.Value which is ICollection.
Hope you got it.

If someone wants to help, you shouldn't be replying like this. This way no one will be going to reply you.
ArunkGeorge wrote: Leave the job to someone who understands the question.
This might be your problem. You should make others understand what you wanted to tell us. Try to focus the terms on what exactly you want.
We all here doing voluntary help to you. We have lots of other work to do. At least you are not paying us for this.
Anyways...
Wish you luck with this.

This is extremely rude, you joined this forum just a day ago and happily insult someone who has contributed greatly to the success of the site and its forums (check out his profile).
You seem to have a seriously poor attitude; may I suggest you take it elsewhere and leave this forum to those who appreciate someone trying to help them, and also know how to behave.

If you don't understand the difference between a hack and an accepted solution, I have nothing more to say.
Form my question, (I hope) it was clear that I had a way of doing things. I was looking for 'better' or 'accepted' ways.
If you feel his reply added any value to me, you are mistaken. It was just rephrasing whatever statements I put in my question, that too with a suggestion to pass the content type as an extra parameter.
There is a famous article about things to do before you ask/answer questions in a forum. I think its by Ayende. Might be good to look for that.

With an attitude like that you are unlikely to win many friends on this forum.
Your original post did say:
ArunkGeorge wrote: Any suggestions or ideas will be greatly appreciated.
And then when someone posted an idea, you didn't appreciate it. Perhaps you should have said:
Only suggestions and ideas that I agree with will be appreciated.

Forgive me for not interpreting that suggestion to pass content type as an extra parameter as an 'idea'. My mistake. Apologies.

I have no problem. I simply pointed out something that should have been self-evident to a perceptive fellow like you.
By the way, you can have the last word on this sub thread, I shan't read it.

Hello Friends,
I am looking for a script in which user can upload an image from his machine and place it over another image.
He should be allowed to place the new image anywhere on the already existing image and should be allowed to resize the uploaded image. Its something like customising a greeting card on moonpig.com where user can upload his image and place it over the card and resize it as well. Could anyone please point me to the correct script. I am looking for this in Javascript, DHTML, AJAX.
Thanks

It is not easy to achieve I guess. You need a strong knowledge on Javascript and ServerSide image resizing to do this.
Let me give you some hint from where to start :
Do a normal upload of an image file.
Put a div and load the image in its background using CSS
like background : url('imgurl')
Now place an absolute position div which allows you to resize just over the div you placed. you can adjust div.clientHeight, div.offsetLeft, div.scrollLeft to position the div on exactly over the image.
When user is done, you need to actually crop the image based on the size of the div which is floating above the div.
Cropping an image is not a big deal, there are lots of codes available for that, Just you need to find the actual value of the Rectangle that the user adjusted for cropping.
This might help you in this regard[^]
Wish you luck in this

hi jayapal,
thanks for pointing me to the links which are really very good tools to be used.
I will look all the possibilities and try and build whatever I am looking for.
my requirement is basically like customising a card or tshirt where user can upload an image from his local machine and preview in our product and proceed with the order;

Hi,
I call a javascript function b from another function a.
in the function b at certain conditions i want to stop the javascript execution and i have did it by throwing an exception by using Throw New Error('Stopi').
It is working well.
1. Is it good to stop the execution of javascript abruptly.
2. Is it bad if the functions are not returned to the calling function and finally to the operating system.
3. I will there be a over flow of stack or will stack keep increasing if i am throwing many such errors.
Meanwhile IE shows the yellow exclamation icon in its status bar as usual that there is a javascript exception. When you click that you can see the error description as 'Stopi' which i have thrown.
Here is an example...
<input type='text' name='name' id='name' />
function validate()<br />
{<br />
isempty('name','Please enter your name');<br />
}<br />
<br />
function isempty(src,msg)<br />
{<br />
var so = document.getElementById(src)<br />
if(so.value=='')<br />
{<br />
alert(msg)<br />
so.focus()<br />
throw new Error('Stopi')<br />
}<br />
}
so i dont have to use if condition when validating. no braces, no return statement, and no need to call focus for every if condition so this code reduces 6 lines and multiplied by number of input controls you are going validate. so i just need to call isempty and if the control has empty value then the user will get an alert and the execution stops.
Please suggest.

Although your approach is not that bad, I would declare a variable which indicates all fields are validated.
<br />
<script language="javascript" type="text/javascript"><br />
var bValid = new Boolean();<br />
bValid = true;<br />
</script><br />
Then I would change the function isempty like so :
function isempty(src, msg)
{
var so = document.getElementById(src)
if(so.value=='')
{
alert(msg)
so.focus()
bValid = false;
}
else
{
bValid = true;
}
}
