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

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 am unable to insert a video which is having table of contents and is capable of playing at required time frame and that particular video is supposed to be a part of adobe captivate project. The video is embedded in a html5 file. Adding a zip file of the html5 file along with xml etc. is unable to load in Adobe Captivate. Please if someone can help me proceed further.
You cannot insert HTML files, but you can insert a web object !
So you just have to publish your video on a server, to copy the link address where it is located on the internet and to insert this link in Adobe Captivate ( insert > objects > web).
Hope it will help you.
I am using Karma commercial template. I have make the plugin for to upload document or any type of file, which will save in database and give option of Preview in front end. I have search many plugins for the same. I don't want to download the file but only wanted to preview the file in read only mode.Please help for the same.
I have used javascript code using javascrip plugin:
var documentViewer = $('#document-preview').documentViewer();
But it is not usefull for word file as it is useful for image, pdf and text file.
The Google Document Embedder plugin allows you to display files (PDF, Word, etc.) and has options that will prevent downloads.

I need a function to convert any HTML table to a excel file!
I like to add a button to my page and once that button is clicked I pass a complete HTML table in to such a function that will generate an excel file and past the html table into the file with the same layout and design!
I appreciate any help with this request.
I am using c# and asp.net
This is a nasty trick, but it works in recent version of excel.
You just save the html table as a normal html file, then just rename it to xls. If your application is a web application use response.setHeader("Content-Disposition", "attachment; filename=order.xls").
Recent version of excel support Microsoft Office XML Formats, so if the previous solution doesn't work, you may want to try to generate the xml from the html table.
See XML Spreadsheet Reference.
What I do, is to generate the xml from excel in the xml format, then hack into it. You can implement also advanced features like automatic filters, and cool layouts. I used a template engine to generate the xml (Freemarker, it's Java stuff, but I'm sure there are template engines also for .NET)
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.

Uploading a PDF is just like any other file. Use the ASP.NET file uploader control:

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
