All I need is to show .doc files in qt application on Linux. No need edit/save or something else.
Is it possible?
Of course it's possible. But the file reading, parsing, and displaying would really be carried out by the underlying language, not Qt. So, if you think about it, C++ and Python and whatever else is quite capable of parsing and displaying what is essentially a text file (or for .dox an XML file).
The implementation details of how to go about that are quite another matter. You have to contend with a huge portion of the file that is merely there to render the file's styling, etc.

I have a question about why file extensions are created?
I found a quote on Wikipedia
"They are commonly used to imply information about the way data might be stored in the file"
what does it mean?
File extension is an identifier which tell the operating system what kind of data and file type they are working with and what associated program opens the file.
if u have an .apk extension file, system can easily recognize it as an application file. If it is an mp4, means it's some kind of multimedia file and can be operated with multimedia applications.
They are commonly used to imply information about the way data might be stored in the file. A normal text editor uses .txt as extension when an html uses extension .html These two files stores data differently.
I wanna perform some check for PDF files.
I wish to check the width of pages and also figure out if the file contains double-pages.
Is there any frameworkfor that?
Thanks!

Indeed there is. PDF::API2 looks like it will might you what you need.
It's designed for creation and modification of PDF files. If not, search CPAN for other PDF APIs.
I don't fully understand your question, but for a start check out these utility scripts that come with the CAM-PDF distribution. Look at the lower half of this web page, e.g. getpdfpage.pl.
A lot depends on the complexity of your PDFs, though.
is it possible to change text and images in a fla file without ever opening it up and then making the swf via command line? I want to make a flash template and save the fla. Then be able to update my text and image name and convert it to swf. I have one template but tons of different text options and background images. It would be nice to be able to copy the master.fla twenty times and just change the source code (will do this from command line) and then convert to swf (via command line).
Any help would be appreciated.
With CS5, you can do half of what you're asking today, by using the XFL file format instead of FLA. Instead of a binary blob, you get an editable XML file and a tree of separate asset files: PNGs, AS3 files, etc. You can then modify the XML or AS3 files programmatically to get your variants.
(A CS5 FLA file is really just a zipped up version of the XFL, but there's no advantage to using that instead of an XFL. In CS4 and previous, FLA was a proprietary binary format.)
The missing piece is an XFL compiler. Adobe currently provides no such thing, and the third party market hasn't yet produced one.
You could use a systems automation tool to drive the Flash Professional environment through the compilation steps. On OS X, for example, either Automator or AppleScript should be able to do what you want. It'll just have more overhead than the command line compiler you were hoping for.
I agree with Jason, there are a lot of alternatives to what you suggest. Keeping content out of the SWF is good practice actually. This is a good way to avoid large files!
Depending on what you 're looking to achieve, there are a lot of solutions available. XML is an option, JSON another.
If you're looking to build a template, any of the above would seem appropriate.
It sounds like you're working from the Flash IDE, as Jason suggests you may want to have a look at another IDE, such as FlashDevelop, FDT or FlashBuilder as they make coding with AS3 a lot easier.
If someone sends me a document (.pdf,.doc,.xls, ppt, .ogg, mp3, png, etc) without the extension, how can I determine the file type? The /usr/bin/file command doesn't always guess right or it simply says that I have a Microsoft Office document. I would like to know exactly so I can add the extension to the file name.
You can come up with your own rules by adding them to /etc/magic
man file for more details. It is tricky to always get these correct however, I have had reasonable success.
Try mimetype(1).
For Perl, look at File::MimeInfo.
Some of the other posters thus far appear to neglect a few things.
File::MimeInfo uses the same MimeInfo database used by 'file' to identify files. So That's unlikely to do anything different.
File::Type is likely to be interesting though, as it relies only on itself, but this leads to a comically long script full of 'if' statements. But this is, by its very nature, unlikely to cover things 'file' already doesn't cover.
The best you can do with unknown filetypes is try cracking them open with a hex-editor, or running them through 'strings' and seeing if you recognise anything. If you manage how to Identify a file, you may wish to go for File::Type as your solution because as far as I can make out, its at least easy to extend.
You can use the Perl module: File::Type
I have a problem where I need a way to display a repeating series of "images" on a computer monitor. Specifically, given a series of text files, I'd like a way to display the contents of said files on a screen in a way much like a powerpoint would.
My current thoughts are to find some tool that will take in a text file of some format, and then output an image which contains the text from the file. Then I'd put it in a directory and have some Slideshow program continuously go between the images in that directory. It's a very hacky solution, obviously.
So, does anyone know of tools that would do such a thing? Or is there a better way to do this? I've looked into the library libgd2, but it doesn't seem to support text-wrapping for images, which is something I'd need.
Thanks!
MagicPoint is a tool for displaying presentations. Presentations are written in a simple plain text file format, much like HTML.
You could easily generate the MagicPoint file automatically and then run it and display the presentation. You can also generate HTML, PS oder PDF from the presentation and display that.
Are you looking for powerpoint equivalent for linux? Openoffice??
have you tried some magic scripting with TeX?
a chain like
tex file | dvi2ps | ps2jpg > output
and define some TeX-Macros?
Showoff's pretty cool. It uses Markdown-formatted slides to create a simple little Sinatra app that you run (with showoff serve), and then view in a browser.
Docutils. See http://docutils.sourceforge.net/docs/user/slide-shows.html
The text syntax is reStructuredText
another idea:
text2gif
To complement the suggestions given by others, if you were going to write a program to do this, it would probably be more efficient to just render the text to the screen directly, rather than converting it to images first. It could probably be done using a canvas or text box component in a full-screen window on whatever window manager you are using (e.g. KDE or Gnome).
I give presentations with Opera's #media projection CSS support. On http://talks.webconverger.com/ you can find a template and an example which you can load in Opera's full screen mode and start sliding through.
So besides writing in a familiar language HTML, it's dead easy to share the slides and even get your audience to look at the slides as you're going through them.
If you are looking for something more flashy, there are tools on the Web to generate animations and what not, and again you would simply use a full screen browser to play it back to your audience.
