There's a good library called PDF Clown, based on java's iText library, which allows you to produce / manipulate PDF files.
Another option could be to allow your users to print to pdf using software such as CutePDF; either they'd need to install it on their machine, from where they could print to a PDF file in the same way they would a printer, or you could install it on the server side & put code in place to produce the file & present it to the user.

PDF Clown is NOT based on iText at all!
PDF Clown is an *independent* and *original* project which has *nothing* in common with iText other than dealing with PDF files.
Please verify what you say *before* posting it, so that false information is not published.

I have a textarea with a name "DocContent" inside Javascript. I want the content of a field [called documentcontent]from database to be displayed inside the "DocContent" text when an event is fired inside javascript. anyone with a solution?
you may look at my partial code:
$query="select documentcontent, uploadDate from document where uploadDate=(select max(uploadDate) from document where documenttype='index' and documentid=12 )";
$result=mysql_query($query);
if ($row = mysql_fetch_array($result))
{
extract($row);
}
?>
<script type="text/javascript">
function Eventhandler(selectobj){
if(selectobj.value=='Modify')
{
document.FormUpdate.DocContent=<?php echo $row['documentcontent'];???>;
}
} </script>

It really depends what your system is like:
1. If you have content that is retrieved from the server that is independent of user input, then all you need to do is request the data from the server when the page loads, and store it somewhere in a JavaScript global variable, for instance. It can then be inserted into the textarea when you need it to be.
2. If you have content that is retrieved from the server based on user input, then you would need to use AJAX (Asynchronous Javascript And XML), to make a request to the server, run your PHP script and return the data from the database can then be returned to your page and inserted into your textarea using JavaScript. Take a look at this article which might help, or look around on Google, for which there are lots of resources on the subject matter.

Hi All,
I have a user control which is loaded last ( after navigating through a series of other usercontrols) in a ASPX page. This last user control contains a Multiline textbox. When the user enters the text in this text box and press enter key, the cursor is going to next line for a moment and returns to the starting position of the Textbox again. When the "Down arrow" key is used to navigate down after this I can see that the enter key press has created a new line, but since the cursor goes to the start of the Textbox the user entry is coming at the start again.
This problem is rectified when this Usercontrol with Multiline Textbox is made the first usercontrol to be loaded in the ASPX page. But this is not my requirement.
Also this is problem is not shown in IE6,IE7 and Firefox browser. Let me know what can solve this problem.
Thanks in advance.

The cursor point could be located with the above provided link, but still one more problem exists in safari. When i press the enter key and continue typing immediately, page is refreshing(probably due to enter key perss), and whatever i enter in second line is erased. So i need to re-enter it again. If i wait for the page refrsh to happen and then type the characters will appear there, other eise page refresh cause the entered characters in secodn line to get erased.
may i know how i can prevent the page from gettign refreshed in safari. i tried return false,event.preventDefault and event.returnValue=false in key Press and Key down.
let me know if any solution is there for this problem.

First of all you need to investigate why the page is getting refreshed when you press enter? Did you set any default button or key?
Second thing do you have enableviewstate set to true for Textbox?
By the way did you try using the TextArea?

Does anyone know of an addon for MS SharePoint which would allow you to publish the contents of a wiki to a more print-friendly medium, such as a word document or PDF? If nothing exists already, I'll have a go at creating something & will make the results available on here; though if something already exists, it would be nice to avoid duplicating someone else's effort  .
Below are some rough notes on what we're thinking. . .
* SharePoint Wiki Pages are held in a customisable list, so can have new columns/properties added. Adding a new "classification" column would allow you to define a page as a TableOfContents, Topic, or GlossaryTerm.
* A new button should be added to allow you to "Print to Manual". This button causes the generation of a manual containing the contents of the wiki.
* When "Print to Manual" is clicked on a TableOfContents page, each Topic linked to on this page is exported to a document. Additionally, each Topic linked to from an exported Topic will be exported. * Each glossary term linked to from each topic will be added to a glossary at the end of the document.
This would allow the ease of a wiki for generating, maintaining and navigating content, and would get around the issue of providing static/printed manuals and physical documentation.
Thanks in advance for your answers and thoughts,
JB

Firstly, don't use iframes unless absolutely necessary. A better approach is to split the page into two by using two DIVs which together fill up the entirety of the page.
It all depends on what your code does and how it operates. I'd recommend this article, which not only gives you the source code but actually explains the process step by step, so you can learn from it.

Thanks Perspx,
i have read the artical its nice tells steps wise how to do, and i am able to drag and drop my div to another div.
But if i have a div inside a bigger div and want to drag and drop it onto another one, i am able to drag but not drop.
I am not sure if i need to do any changes in my code since for the first i pass the id of the DIV i need to drag and drop. So if i put that div into a bigger one and pass the id why it doesnt drop????
i am not sure where i am going wrong
Thanks

You can use:
System.Math.Round(Decimal, Decimal places)
There are a number of options for using this, you'll need to look into which one is most suitable for you.

This is a general question about the size of the DOM and garbage collection of released objects.
I find myself in the position of referee between some opposing designs and would like to ask if anyone has experience with object disposal in the DOM.
Basically the two approaches are to re-post the page whenever there is a request for a new component or build a monolithic page that keeps being dynamically refashioned by disposing of existing DOM objects and attaching new ones.
It sounds complicated because it is and I know in theory that it can work but I have concerns about trying to put 10 Kg of stuff in a 5 Kg system.
I don’t want to dismiss the monolithic design out of hand for two reasons; first, I need to work with the person who proposed it for the next year and don’t want to make an enemy, and, second, she is an employee and I am a contractor so I don’t want to make an enemy and have to watch out for hidden daggers, a point the project manager cautioned me about.
When I confronted the person in a head on confrontation the PM said that she liked that I broke the grip on power in the team but to beware that this person holds a grudge and probably will try to get back at me in the future. I don’t need this drama but here I am dealing with it every day.
I am personally leaning towards post a new page whenever a major change is requested like working on a completely different component and using AJAX to service minor changes in the page like requesting details of the component that is currently being worked on but I want to be diplomatic because of what I mentioned above.
Do any of you have any horror stories, or success stories, about implementing a monolithic system where the initial page is served up and major revisions to the DOM are happening for an extended period of time?

That's a tough one. Because even if there was a solid technical reason not to do what she's suggesting, you'll still need to deal with the drama. Can you take this gal aside, get her in a situation where she doesn't feel like she needs to be defensive about her suggestion, and together hash out aspects of each strategy that you can agree on?
As for the technical aspects...
I can tell you that the IE DOM will be a constant thorn in your side for the monolithic system - slow, memory intensive, and buggy garbage collector. You can side-step a lot of the issues with the latter when you're reloading the page periodically. You can avoid some of this by utilizing optimized 3rd-party libraries like jQuery and ExtJS to do the heavy lifting for you. With IE8 looking to launch as the slowest major browser on the market, you're not going to see relief any time soon. Rarely a week goes by where i don't curse IE due to some such problem.
Monolithic pages have a bad tendency to reinvent the wheel, badly. In a traditional web application, you just link or redirect to the page that implements the tool your user needs next; in a monolithic app, you must provide most of the functionality the browser would normally give you for free: identifying the tool, loading the code and data, refreshing the screen... And while browsers continue to improve and refine their navigational UIs, you won't benefit. You'll have to jump through hoops just to get features that most browsers have provided for years, even to static HTML pages, like as bookmarking. And you'll have to figure out what you want to happen should the user accidentally hit the "refresh" button after performing extensive in-page navigation... I occasionally use a bug tracking system with a monolithic web UI (intended to closely mimic the desktop version), and it's a huge PitA - what's more natural than bookmarking a bug report, or pasting the link into an email?
If you want to support clients without client-side scripting, or with a very different set of capabilities from the average desktop browser, you'll have to write a completely separate UI. If you're planning a separate "mobile" version anyway, this may make sense.
Testing and debugging will be more difficult when you can't just request a page and examine the response. This can be mitigated somewhat by using a good, RESTful, API for your AJAX requests under the hood. It probably goes without saying that you'll want a browser that provides a good DOM inspector for debugging update and layout problems.
OTOH, a monolithic design can make sense if you're working with a system that really does not make much sense as a web app. An app that maintains state in a way fundamentally incompatible with the REST architecture. Where navigation between meaningful URIs is impossible or at least very undesirable. Where you would spend a lot of time and effort effectively subverting the normal operation of the browser anyway.

Thanks Shog9 you have confirmed my suspicions.

This person doesn't take suggestions. I tried on Friday evening, after everyone else left the office, to tell some stories of prior projects I have worked on that went bust because they were bloated and/or didn’t address a customer need to which I received the reply, "This is my baby. I have been working on this design for the past two years".
I will just have to figure a diplomatic way to get the point across that we are asking for trouble if we are doing extraordinary things to accomplish ordinary results.
Then when that fails we will just have to slug it out in a metaphorical sense. I did it once before and that is when the project leader congratulated me for not being rolled over as the others on the team have and cautioned me about dotting my “i”s and crossing my “t”s because this person will try to get back at me.
I really hate drama like this but it seems it is an integral part of this contract.
