Is there any way that I can embed a .exe file in a .pdf, .doc, .xls, or .ppt file in such a way that upon opening the containing file, the document processor will run the .exe automatically without the user intentionally executing it?
Yes, this is totally possible and pretty easy to accomplish - so long as you have an active exploit in the PDF viewer. Check out one of the many Adobe Acrobat Exploits in the Metasploit framework. Next you can use a download+exec shellcode to download and execute your payload, err I mean ".exe".
You can embed files with EXE or any other format. However, the ability to have the EXE run automatically depends on the viewer application and its security settings. This PDF feature has been exploited by many malware. So, there is no guarantee that it will work on all end-user systems. Be warned that if you make this feature a part of some commercial application, then security software will soon flag it as a malware, which can adversly affect your company's reputation.
Yes. Besides using an exploit, you can just paste the file in using Acrobat Professional. Acrobat allows you to add arbitrary attachments these days.
If you make your PDF files with pdflatex, you can embed any file using the embedfile package. I use this frequently to add all kinds of files to PDF files. They show up as attachments.
\usepackage{embedfile}
\embedfile{my-wonderful-file.exe}
You can also use the Acrobat GUI to do it.
In short, no. These file formats have no provision for embedding a Win32 PE executable inside of them.
For the Office files, you could use VBA to write a script that runs when the document is opened.

I have a set of custom formats that I would like to use in any new Excel files that I create.
I found this approach, Save cell styles to use in all new workbooks, but it relies on using a template which I cant use as I am using a cloud server so I don't have access to the XLSTART folder.
Using code is fine if I must, but I don't have experience in this space.
I understand that I may be able to create an Excel addin to hold the formats, and create a new workbook from that. Is this addin the way to go?
Please help!
Is this a desktop Excel program? If so, you might try adding another custom startup folder. (Depending on version it might be different, in 2013: Excel Options - Advanced - General - At startup, open all files in:.) Now if you put a file here, it will auto-open on Excel startup, just like the files in the XLSTART folder.
(But to be honest, I don't see how this will help you, since XLSTART - or any automatic startup folder - is useful if you want macros available. I'm not sure about templates.)

Though applescript appears to be a scripting language like any other (wikipedia/applescript), for reasons I don't understand it seems these scripts are often saved as binaries. It seems like this isn't an issue for someone working on a Mac with a mac-based text editor that can open these scripts into a plain-text format where they can be edited and read, but for the rest of us, we just see gibberish. For instance, Github has many examples of .scpt files committed to repositories instead of/without the plain-text equivalent (a bit of Googling suggests this would be a .applescript file instead)
Question: Is there an open-source tool that can parse and serialize these binaries so that they can be viewed/edited in a standard plain text editor and saved back as .scpt?
(My context: I'd like to provide a user-friendly, os native button-click way to launch my application on a mac, rather than tell users to open a bash terminal and type stuff.)
Edit I only have access to a linux machine, I don't own a mac.
Instead of trying to create an AppleScript on a non-Mac, what you can do is simply name your shell script file with a .command suffix and make sure that it has execute POSIX permissions for the user. The user can then double-click the file in the Finder to execute your script instead of having to enter Terminal commands.
If you would like to take advantage of AppleScript commands within your shell script file to add some simple GUI functionality, you can use the osascript command.
BTW, for reference: on a Mac the application "Script Editor" (or "AppleScript Editor" on older systems) is generally used to create AppleScripts. It provides several save options - the .scpt binary and .applescript plain text files you noted as well as .scptd script bundles and .app standard, double-clickable applications.

I have a basic Java program with output of "hello world". What I want to do is to write a Java script to run that program and import that into Unity so I can use it in my program in Unity.
Is there a way?
You can communicate with Unity from a Java application trough OSC(Open Sound Control) and send text, commands triggers or load an external file(xml or similar) into Unity.
Unity and Open Sound Control
http://www.sundh.com/blog/2012/07/unity-processing-demo/
On unity you have to use function OnGui() to show text.
In the related documentation you have many example.
For show message in a console just use in a javascript:
Debug.Log("Hello world");
You can also put files in your /Resources folder in your unity project, then load them at run time. These can be pretty much anything. models, prefabs, materials... could be text files (maybe comma delimited txt files, that you parse) or more typically .xml files that you can easily access and extract data (text) from.
to load any resource file, use resources.load()
http://docs.unity3d.com/Documentation/ScriptReference/Resources.Load.html
Don't use OnGui as this is bad for performance rather use Canvas to edit and place the text you prefer on or in (parent) object you want.
to make this look better put the font size higher and the width and height lower.
this will make it look sharper.

This isn't necessarily a coding problem, but users here would be the perfect people to ask.
Is there an easy way to view and edit a simple text file (.txt seems the most obvious) on a browser (I use Chrome). I'd like this file to be stored locally as well, preferably in my dropbox folder so it's backed-up at all times.
I tried looking for a chrome extension that does this, but after 3 failed attempts I thought there might be a manual way to do this.
I don't care about the format as long as it's common and can be opened on other computers if need be.
Paste the following into your browser address field to get a ready browser notepad:
data:text/html, <html contenteditable>
You can type or paste your text here, edit and then save as page or copy somewhere. Suggested by Jose in his blog.
HTML5 has a File API: http://www.html5rocks.com/tutorials/file/filesystem/
Once you read that you will realize that you can use a blob builder to write to a file, then post that file back to your browser which will automatically download it.
var bb = new BlobBuilder();
bb.append(message.value);
var blob = bb.getBlob();
location.href = window.webkitURL.createObjectURL(blob);
This is an old question, but I've wanted this ability for a long time and finally found a solution that works for me. In Chrome, set up a Workspace folder as described here.
I wanted to edit a markdown file, so I created an empty file called editable.md in my workspace folder. With Chrome developer tools open, in the Sources pane, I can double click this file to edit it. Even better, I have the MarkView plugin installed, so I see a nicely rendered version of the markdown in the main view.
I think there's a reason why web browsers and text editors are called the way they are. Why would you wan't a functionallity like that? There are other tools for that.
Maybe your answer is a server which handles this kind of requests - allows information to be added, and stores it in it's own dropbox folder which is shared with other users.
The main problem is that browser can't that easily access files on your computer if those aren't cookies, tmp files.

I'm looking for a library (or command line tool) to turn MS Office documents into either plaintext or HTML (for conversion to text).
It must run on Linux (not via Wine!).
I found antiword, but the last release was 2005, so it won't read the new Office 2007 formats.
I need it to read Word, Excel and Powerpoint documents
The new office 2007 format is just (ZIP) compressed XML.
All the text (in at least the .docx format) is located (once you decompress the file) in the word folder, document.xml file. Strip it from all the XML tags and you'll get the text. You'll lose the formatting no doubt, but if you want to do text indexing or something like it format isn't relevant anyway. The order is preserved.
I haven't analyzed Excel and Powerpoint but the approach should be similar. Excel might be trickier, depending on how are the cells stored in the XML file.
The Apache POI library can extract text from office formats. This is used by Tika in Lucene. Tika can be executed as a command line tool:
curl http://.../document.doc \
| java -jar tika-app-x.y.jar --text \
| grep -q keyword
PyODConverter for automating OpenOffice. Use it to do the conversions.
OONinja example converting Doc to PDF but any OpenOffice supported imports or exports should work. Also has the advantage of working Headless if required.
other options include,
Abiword
or you really just want to deal with command line WvWare but I don't think it supports Docx,
You can use Autonomy Keyview with the appropriate licence to use in your application. It seems to be extremely powerful and can extract text from almost everything; we use it to identify text within arbitrary format files.
I've no idea what the licensing terms are, but they're available from your account manager :)
