I want to convert my PDF files into flip book using Adobe Reader. How to convert it?
You can't convert your PDF files into a web based flip book using Adobe Reader but you can use one of the FlexPaper components to do so, we have both GPL and commercial alternatives

I want to generated a pdf using XSL-FO file. Adobe now has the capability to embed 3d objects inside PDF documents.
http://blogs.adobe.com/tcs/2011/01/framemaker/interactive-3d-models-in-documents.html
Now I just want to creat a PDF file from FOP library which supports to embed 3d object. Is it possible?
Not implemented, yet (2013-11-06). Consider implementing support for it yourself and submitting a patch to the Apache FOP project.
Can you use PurePDF to view files or is the api only for writing them?
Based on the PurePDF Project Page, reading and extracting information from PDFs is supported:
read existing pdf documents (extract strings, streams, images and all the informations from them). See HelloWorldReader.as for an example
However, if you're looking to view / rasterize a PDF, that's a much more complicated task and doesn't look like it's supported as part of PurePDF.
I suggest converting the PDF into a swf file. There are a number of projects out there (including free / open source) that convert pages into SWF files, including being able to still extract the text. :D
It looks like you can either navigate to the url of the PDF (maybe in an HTML component?) , OR a richer solution might be to use the open source flex paper : http://flexpaper.devaldi.com/
Is there a pre-existing library to extract plain text form Open XML file formats (e.g. docx, pptx, and xlsx) files?
I require this to populate a lucene.net index.
I've found this example which extracts text from docx and it seems to work okay. But before building my own solution based on this I was wondering if there's something already available for the other file formats?
Before spending cash, it may be worth looking at the IFilter interface - these were/are designed to do exactly what you want.

http://www.codeproject.com/KB/cs/IFilter.aspx
(Some links at the bottom of the codeprject link).
MS provide IFilters for office file types.

I know that we use this technology to allow us to index PDFs using Lucene but I did not write the actual code and cannot be of much use I am afraid.
If your Google-fu is strong I am sure you can dig up more examples of using IFilters to do exactly what you want.
watch aspose.com, they have a good library to handle both ppt and pptx.
You can try Toxy, an open source text/data extraction framework for .NET. For now, it supports xls, xlsx, doc, docx. It will support pptx in version 1.5 very soon.

I want my Qt application to be able to save simple vector graphics to clipboard in a compatible way. On windows I want to be able to paste the graphics into Microsoft Word or Powerpoint. On Linux I want to be compatible with the Open Office.
Which format would you recommend? Can Qt generate EMF in an easy way? Is SVG an option?
Update:
My current plan is to add a piece of native win32 code to render the graphics to emf on windows. This code will not be available on linux.
The QGraphicsView class and its associated helpers can render to a QT metafile format through the QPicture class (for which you could write a translator to EMF), to SVG through the QSVGGenerator class and to postscript/pdf through QPrinter. It can also render to bitmap formats and various other targets.
AFAIK it doesn't have a generic 'render to EMF' facility - you would have to write to something else like the QT Metafile and convert to EMF. If you only need a subset of the graphics primitives you might only need to support that subset in the translator. Otherwise you could go from SVG, which you can get directly from QT through QSVGGenerator.
I have an EMF-generating PyQt QPaintEngine class here: https://github.com/jeremysanders/veusz/blob/master/document/emf_export.py. It uses the pyemf library, but I think it would be fairly easy to port to C++. Unfortunately the files are not compatible with OpenOffice as OO has pretty broken path support in EMF files. It also converts text to paths for WYSIWYG.
I have a client of my web based application who heavily uses the data from our system for powerpoint presentations.
We currently allow data to export in more traditional file types...PDF, CSV, HTML, and a few others. Powerpoint doesn't seem to be really automated.
Is there a way, on the ASP.NET server side, to automate the creation and on-demand download of a powerpoint file format for a report from a system?
There's some documentation on MSDN about the OpenXML format that they're using:
Manipulating Excel 2007 and PowerPoint 2007 Files with the Open XML Format API (Part 1 of 2)
Manipulating Excel 2007 and PowerPoint 2007 Files with the Open XML Format API (Part 2 of 2)
In this article, Steve suggests using Aspose's Slide application.
He also explains step by step on how to generate the PowerPoint file.
Here are some code excerpts (in VB):
Opening an existing PowerPoint file:
Dim fs As System.IO.FileStream = _
New System.IO.FileStream("c:\mypath\myfile.ppt", _
System.IO.FileMode.Open, System.IO.FileAccess.Read)
Dim MyPres As Presentation = New Presentation(fs)
fs.Close()
Looping the slides and outputting their template formats:
Dim slides As Slides = MyPres.Slides
For i As Integer = 0 To slides.Count - 1
Response.Write(MyPres.Slides(i).Layout.ToString + "<br>")
Next
In his article, he describes more in detail on how to do it.
Well you have two ways of really doing this, without third party tools. The first would be with Automation of PowerPoint, but that requires that your server have PowerPoint installed. The second is to utilize the new pptx file file format and generate the powerpoint document using XML.
I have found that the best way to get started on the XML side is to simply create a powerpoint that does what you want, then save it and look at the XML. You can also review the microsoft documentation. Overall working with the XML formats is pretty easy.
Lastly, there might be some third party items out there, but be careful that they don't require COM automation.
In regards to the previous poster, your statement is incorrect.
You really only have one option for server side ASP.NET automation of this process.
Use the open xml links mentioned by Ben in the original answer...
Manipulating Excel 2007 and PowerPoint 2007 Files with the Open XML Format API (Part 1 of 2)
Manipulating Excel 2007 and PowerPoint 2007 Files with the Open XML Format API (Part 2 of 2)
The reason for this is that server side automation of office is completely unsupported and is bad coding practise, running com automation servers that are designed for interactive usage in a non-interactive environment is a potential recipe for disaster.
so in summary use the open xml api and generate your pptx's.
There are also other third-party options similar to Aspose Slides, such as OfficeWriter's PowerPoint Writer.
I'm not exactly sure how Aspose Slides works, but with PowerPoint Writer you have an existing, formatted PowerPoint presentation with data markers in it, the you process it with PowerPoint Writer to replace the data markers with data. Here are some examples.
there is another method ,convert your power point presentation to images or xps(silver light presentation) and then use some sort of json(jquery) to show and download them.
i implement the images and xps silver light presentation in my web application
