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:

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.

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,
I am looking for something like www.moonpig.com where user can upload an image and resize, move and put it over a card and preview his card with his image on it. basically uploading an image over another image and previewing it.

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;
}
}

hi,

besides IE shows the yellow error exclamation...

Hi,
I have a datagrid(with update and cancel buttons) and I have implemented sorting and custom paging on this datagrid. Everything was working fine. BUT when I sort the contents of the datagrid or change the page of the datagrid and then if I click on the Edit button, for example if I click the edit on the first row of the second page then the row which the editItemIndex highlights is the first row of the FIRST page. Similar problem faced if i sort the datagrid and click on any edit row of the sorted datagrid. The main problem lies in accessing the row, in my code i use
dataGrid.EditItemIndex = e.Item.ItemIndex;
But the above does not work properly. I even tried-
dataGrid.EditItemIndex = e.Item.DataSetIndex;
But the above also does not work.
The entire code is mentioned below for your reference. PLEASE HELP ME. THANKS IN ADVANCE.

Hi,
I have a developed a mobile client application for which i wants to make a server application.
I have my website which have a database to it and i wants that both server application and my website will share the same database.
The main feature of the server application i to make continuous http request to a URL and capture the response and perform according to the response.
But i dont know what to do in this regards, i am totally stucked to this please help me what to do.
which kind of application i have to make either web application or web services & how i will integrate it to my website.
Thanks in advance

I believe what you want to do is:
1) Store the database on your website
2) Create whatever web-app you want on your website
3) Create a data access layer to your database which exposes a series of webservices for your data.
4) Modify your mobile client application to use those webservices to access the data which is stored on your website.
You can poll the webservice as often as you would like to get the latest data from the server. Or, maybe you should think of a "push" architecture where the webserver would generate an email to the client indicating that data has changed, maybe even send the new data to the client as an XML attachment which could be used to update the client.
Good luck.
