I am developing a xmpp chat client, and i want to add functionality of sending files like zip, pdf, docx, ppt, images etc. I research on net about it and come to know that XEP-0047(In-band-bytestream) is good to send files in base-64 form, and i am able to send and receive base 64 data, but my question is- I can convert a file to base 64, but after receiving it, how can I retrieve it back in its original form?
And if not, then is there any such thing is possible by Strophe that we can upload file(to send) to the server and then send the corresponding link to receiver so that he can download it, if yes then how to upload and download file using Stophe?

I have an application that allows users to download files from the server, these files can be pretty much anything.
I am at the point where a user is able to download a file to their phone but I can not figure out how to allow the user to open the files from the app, for example say a user has download a word file (.docx), when they select the file in my application I want the file to either open in the default .docx viewer or present the user with applications that can open the file. (Similar to how WhatsApp handles it)
I have tried using Linking.openURL('file:///pathtofile/filename.docx') but I get an error saying Could not open URL file:///pathtofile/filename.docx, exposed beyond app through Intent.getData()
I'm currently using Expo and would much prefer not to have to detach my app.
Update:
I ended up detaching from Expo and built native modules to handle this.
I know this question has been asked a lot of times already but unfortunately none of the answers have helped me. I want to upload an image file to my remote Web server (Apache). In my Excel cell, I have the file path of an image and want to use VBA to upload that file to a remote server.
I can't use any 3rd party tool in conjunction (like WinSCP), because that will make my product not very "portable-friendly". I was fine with Windows FTP, but it doesn't seems to be supporting passive mode and hence I also can't use that.
There are some threads which used IE to upload the file, and some which I believe are uploading via POST request by reading file in binary mode.
I want to replicate something similar to uploading files via HTTP POST on a website.
How can make a uploader file in vb6 to work easyly and can be uploade files into host.
For example (images or multimedia files or other format) and size > small size files for exampe > 500kb or 1 mb , 2 mb or upper sizes .
Please help me to can find any way to designed without ftp protocols.
I think it is possible to use of msxml refrences but i don't know how can designed it by msxml .
[thanks]
You could upload to a HTTP like dropbox. The downside of simple HTTP file transfer is that it is fairly easy for somebody to grab your credentials using a common tool like Fiddler. However that is also the case with FTP just a bit harder. The upside to uploading to dropbox is that you could have any file size (providing you have the space on your dropbox account).
I haven't tried using the dropbox upload api yet but you can read the documentation here, take a look at the PUT and POST methods: https://www.dropbox.com/developers/core/docs
If you just wanted to upload to dropbox and you have the dropbox client installed you could just save the file to the dropbox folder on your computer and it would auto upload.
Let's say i have a list of files. When I click on one it will get downloaded and saved into the app's isostore. Then it's opened in the default viewer/editor on the windows phone like this:
Windows.System.Launcher.LaunchFileAsync(file);
But when I make some changes to the file and want to save it, it can't, because it's a read-only copy of the file. Is there some way to get write-access to the file or else some public/shared (iso)store that every app has access to? The goal is to download the file, edit it and upload it back to the server.
Per the Windows Phone documentation, the Windows.System.Launcher.LaunchFileAsync API is not implemented for the Windows Phone platform:
Windows Phone 8: This API is not implemented and will throw an
exception if called.
In regards to saving the file so that it can be accessed by other applications, this is not possible, unless the file you are dealing with is a photo, in which case you could use the Media Library API.
I have a server from where a single consumer me download MP4 files. I would like to add the username to the meta-data of the file at the time the user clicks "download". Amazon does something like this for the MP3 files.
Now, a slight variation to this is how would I do the same thing if the files are on Amazon Cloudfront.
Thanks!
You would have to route your request through your web server.
Logged-in user clicks
Web server downloads the MP4 file from S3 to its file system.
Web server uses an MP4 editor to add the correct MP4 metadata to the file.
Web server serves the MP4 file back to the customer as a download.
S3 is dumb file storage, so you can't do any on-the-fly editing or processing. Any such work must occur on a machine with a CPU.
As such, the question you posed could not be accomplished in any meaningful way using CloudFront, since the traffic needs to route back through your server for post-processing anyway.
