I used itextsharp library to generate and fill PDF files however; the issue i am having is when you open some of these files in Chrome i get the image below but it does work perfectly fine in IE
I found my own answer, it turned out that when i save the file to the Db i did not add the .pdf as an extension to the file that's why it was coming like that.
because the form data is saved first then retrieved later.
Thanks for the replies.

I am using Qt PDF module to open a PDF file. How can I take a screenshot of part of the file and save it?
Since I guess this is impossible, I will convert the PDF to a image using pdf2image and work with images
I have an intranet site that lets users open files in the browser (by prompting for download). One of these files is an .xlsx workbook that contains hyperlinks which point to different locations of files (.pdfs, .docs) on the file server in which the .xlsx workbook is located.
It seems the file server path to the workbook is replaced by a "Temporary Internet Files/Content.IE5/" path, leading to the warning "cannot open the specified file" in Excel.
I tried downloading the Excel document first and then following the links, but they're still opening in the temp internet location
EDIT:
For instance, when hovering over the hyperlinks in excel they read: "file:///C:\Documents And Settings\%username%\Local Settings\Temporary Internet files\Content.IE5\40WSS3CB\" + filename
when they should read: "file:///\servername\Departments\Read\" + filename
How can I still open the excel file in the browser and retain the hyperlinks inside and have them not be replaced by the temporary internet files path?
can someone point me in the right direction ? Thanks!
I did some testing, and it almost comes from the way you store links. If you browse through the dialog of Insert hyperlink, then you will end with relative urls. That is, the common base is stored as a reference to the current xlsx file path, and the remainder is stored and displayed as link.
You are totally in the issue Richard Hare mentions, so following the procedure from the microsoft support site should help. It did the trick on my test at least.
UPDATE to sum up down.with.the.bass comments :
One option to solve this, if doable, is to open xlsx file from its network share location and not through the website. If it is forbidden for whatever reason, you may be able to update the links using a macro.
Do you have an option like "Update links on save" enabled?
In an earlier version of Excel it was set in Tools, Options, General-tab, Web Options-button, Files-tab.
Try unchecking it and resaving the document.
I just did in my server the same task (the one I understood):
Uploaded the hyperlink to some asp.net webpage.
<p>
test<br />
</p>
The "book1.xlsx" file has inside a cell which refers (hyperlinks) to some share directory (i.e \\NHSTXX1\TEST\MS OFFICE EXCEL - \\SERVERNAME\FOLDER\OTHER FOLDER )
And when clicked the hyperlinked cell, it opened the share directory I was looking for.
I tried with Firefox.
hope this help
Hyperlinks shouldn't just mysteriously change. I saved an excel file with a hyperlink in it - opened it with html - saved it - open it in excel again - and the link stays the same. So I'm not sure how this could be happening to you(if I understand your situation correctly).
I have files in e pub format. I have to show their contents to the user. How do I read them in asp.net? Can it be done through javascript?
Authoritative? What could be better then a StackOverflow answer? I started from this question ( https://stackoverflow.com/questions/4870594/is-there-a-c-sharp-epub-library ) and gleaned a few usefull links:
Usefull information on displaying text in a web browser using javascript so it paginates nicely: HTML book-like pagination
A C# open source library for reading ePub files, the sample code on the home page includes how to get the contents as HTML: http://epubreader.codeplex.com/
There are other libraries which may come in handy if the ePub reader library on codeplex doesn't pan out: http://sourceforge.net/projects/epubsharp/, and http://www.aspose.com/categories/.net-components/aspose.words-for-.net/default.aspx
You can't do this with just JavaScript of course, you'll have a server side like a web service or code behind on your asp.net webpage which opens the epub file, extracts the contents as HTML and returns it to the client, but I think there is enough here to get you started.
Just to add then i suggest the steps:
Step 1: unzip the file using C#,.net code having some third party library.
Refer : recommend a library/API to unzip file in C#
Step 2: Check whether in the extracted folder there is only one file or more.
Refer: How do I find out how many files are in a directory?
Step 3 :Read the file using stream reader in c#.net
Refer: http://msdn.microsoft.com/en-us/library/aa328963(v=vs.71).aspx
http://www.dotnetperls.com/streamreader
Epub file is actually a zip archive that contains
xml files for meta data, table of contents etc
xhtml or dtbook (xml) + gif, jpeg, png, svg + css for content
To be able to display epub you will have to be able to handle all of the above. Here Reading ePub format you'll find what you have to do to open epub step by step - it's an example for iphone, but it should be enough.
I want to export a few Pages to pdf/xls. By Pages I mean as the eye sees it - a screenshot of the Page's contents. I know how to build pdf/xls documents using 3rd party tools but is there any way to quickly export the rendered contents of say a Panel?
edit: maybe a tool that can render the page's output as a browser would, and save it as an image file?
There is an open source console program named wkhtmltopdf which you could call from asp.net to convert the page. It can convert to PDF or an image with wkhtmltoimage (JPG, PNG, etc.) using the webkit rendering engine.
Check my answer to this question to see an example of how to convert from a html to a pdf using C#:

Can someone point me to some code/tutorial on how to upload pdf files and store them, then moreover how to use a pdf reader to display the file as read only in an asp.net application.
Is there a PDF reader already in the visual studio toolbox?
The approach I would use in this situation is to upload the PDF as you would any other file, then use a tool like GhostScript to convert the PDF pages into image files that you can show in ASP .Net.
Here's a tutorial doing that in C# http://www.codeproject.com/KB/cs/GhostScriptUseWithCSharp.aspx
Adobe provides (on acrobat.com) a free service which provides you with the ability to upload pdf (and also other types like doc...) and then embed a nice flash interface for displaying the files on your page.
It's pretty helpful as you can store some 5 gigs of files here.
But if you want to let the users upload their own files then this won't help you.
PDF is a final format file, ie its is read-only for the most part and can be embedded into the page via the <object> tag, except if you mean downloadable by the user.
Displaying PDF is generally done by rasterising to an image format for display (ie as an image on the page or via a richer interface (with zooming etc) through flash/silverlight etc.
You can use [GhostScript][1] to interpret PDF files and convert them to an image.
[1]: http://www.GhostScript .com
Uploading a PDF is just like any other file. Use the ASP.NET file uploader control:
http://www.codeproject.com/KB/aspnet/fileupload.aspx
In order to view the PDF in an ASP.NET application, you could either depend on Acrobat being there or use a PDF Viewer control.
The company I work for, Atalasoft, sells a PDF Reader add-on to our web viewer controls. You can learn more here: http://www.atalasoft.com/products/dotimage/pdf-reader
