I'm developing a Linux application that has its own file format. I want my app to open when you double-click on those files. How can I register a file extension and associate it with my application on Linux?

Hi there, I'm developing an application targeting .NET Framework 2.0 using C# for which I need to be able to find the default application that is used for opening a particular file type. I know that, for example, if you just want to open a file using that application you can use something like: System.Diagnostics.Process.Start( "C:\.....
Hi, I have a few questions related: 1) Is possible to make my program change filetype association but only when is running? Do you see anything wrong with this behavior? 2) The other option that I'm seeing is to let users decide to open with my application or restore default association ... something like: "capture all .lala files" or...
I have a table with a binary column which stores files of a number of different possible filetypes (PDF, BMP, JPEG, WAV, MP3, DOC, MPEG, AVI etc.), but no columns that store either the name or the type of the original file. Is there any easy way for me to process these rows and determine the type of each file stored in the binary column...
I am working on an ASP web page that handles file uploads. Only certain types of files are allowed to be uploaded, like .XLS, .XML, .CSV, .TXT, .PDF, .PPT, etc. I have to decide if a file really has the same type as the extension shows. In other words if a trojan.exe was renamed to harmless.pdf and uploaded, the application must be a...

Hey everyone, I am working on a script that will process user uploads to the server, and as an added layer of security I'd like to know: Is there a way to detect a file's true extension/file type, and ensure that it is not another file type masked with a different extension? Is there a byte stamp or some unique identifier for each typ...
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. ...

I'm building an application (a side project which is likely to enlist the help of the stackoverflow community on more than one occasion) which will need to open a variety of file types (i.e. open Word documents in Word, not natively in my application). I've been playing with some code for looking up the default application for the file ...
I'm using a simple web-based PHP application that outputs a table as a spreadsheet header("Content-Disposition: attachment; filename=" . $filename .

I've recently started using Mercurial and when I reverted one of my .SQL files, Mercurial performed a binary comparison. This obviously limits the visibility of the changes that were made, as there is no diff. Is there an option to set file types to do a string compare? I'm using Tortioise Hg 0.8.1 with Mercurial 1.3.1. ...
