I want to store images like finger prints and data in a single file so i can send that file via mail.Can anyone help me out here.
thanks.
Best way to do this is with a zip file. If you're doing it from the desktop, just use a tool like IzArc or the built in zip tool.
If you're doing it in code from an application, DotNetZip is a library that can help you and has a lot of examples on how to use it.

I'm trying to use GUN to create a File sharing platform. I read the tutorial and API but I couldn't find a general way to upload/download a file.
I hear that there is a limitation of 5Mb of localStorage in GUN, if I want to upload a large file, I have to slice it then storage it into GUN. But right now I can't find a way to storage file into GUN.
I read the question from Retric and I know how to store the image into GUN, but can I store the other type of Files such as .zip or .doc File? Is there a general API for file storage?
I wrote a quick little app in 35 lines of HTML to demonstrates file sharing for images, videos, sound, etc.
https://github.com/amark/gun/blob/master/examples/basic/upload.html
I've sent 20MB files thru it, tho yeah, I'm sure there is a better way of splitting it up into 2MB chunks - that is currently not automatic, you'd have to code it.
We'll have a feature in the future that will automatically split up video files. Do you want to help with this?
I think on the download side, all you have to do is make sure you have the whole file (stitch it back together if you do write a splitter upper), and add it to some <a href=" target. Actually, I'm not sure exactly how, but I know browsers support download file attributes for a few years now, where you can create a download link even of a in-memory file... but you'll have to search online for how. Then please write a tutorial and share it with the community!!
I would recommend using IPFS for file storage and GUN to store the links to those files. GUN isn't meant for file storage I believe, primarily user/graph data. Thus the 5 MB limitation.
I am using USRP1 along with gnuradio. I want to store received data in a file using file sink. I would like to have an idea about the flow graph and with what extension I can store the file and how to read the data from the file. Thanks in advance.
Did you search online? Pretty common task that many have documented. For example, check out Dynamic file names in GNU Radio, which links back to a page of examples including writing I&Q to file 2
Hello i want to get or dump rcdata from ressource of file with vb.net
how a can do this and Thank you

I'm not aware of any library for doing this directly. Vb.net doesn't like playing with raw data pointers. However there are command line applications that can do this for you.
Have a look at these freeware options:
Resource Extract
Resource Hacker
Then you could just launch the process and parse the outputs.
I'm brushing up on my VB.NET skills for a future project I will be working on. This application will be very data intensive, requiring 20+ data tables, user supplied images, and possibly even short audio/video files.
I want to be able to save all of this information into a single, external file, so that the user can share what they create with the world.
Ideally, I would like all the text based data to be stored in a database format that I can easily work with, preferably via the entity framework.
Pretty much all the information I'm finding relates to only saving a single text/XML file, and that will not really work for me. Can anyone point me in the proper direction, or suggest a method that will let me save the data?
I'm working inside Visual Studio 2012 Pro, with a Visual Basic Windows Form Application. Please let me know if you need any additional information.
I'll expand my comment to an answer instead.
As previously mentioned this sounds like a zip file. In this you can:
Have a file called databasetables.txt or whatever containing the database tables.
You can have Audio, Video, Images etc in respective folders. This way when you open your file you can just load all files in the Audio folder to get the expected files.
You can have information stored in xmlfiles.
Endless posibilities...
Just keep in mind that you might want to load all this only into the memory of the computer so you dont extract it onto the hard drive.
And you dont have to save the file as .zip to open it as .zip, just select your own cool suffix which will look neat :)
It would be far to much for me to ask for a full solution. However, could you point me in the right direction in what I need to look up, learn etc as its the first time I am going to attempt something like this.
What I want to do, is in my Mac application, have a list of items which are files which I want to store online. Then from inside the application the user can download any of the items stored at that location online. If I add new items to download online I want the app to automatically add them to the list for download.
That make sense? Anyway, its the first time I have done anything like this using an online server and accessing it via an app, so any support would be hugely appreciated.
Sounds like you want an ftp type server, you can then get list of remote files, upload and download file, if you do search for Cocoa ftp I am sure you will find someone has written a nice wrapper class for ftp, there are even complete open source apps for ftp whose code you can examine, FileZilla, other you could just use NSTask, and call the ftp command line tool on all macs.
