I have a rails app with file attachments using paperclip. Images and pdfs work fine in that if I click on the linked attachment, the image or pdf opens. If I right click, I can do a save-as.
However, with Office files such as word.docx, I can only download the file. If I go do Dos and type the filename, it will open in MS word. Therefore, I think that I should be able to use the system or system call and just pass the attachment name from paperclip (ie attachment.image.url) to dos and the file should open. I think the command I want would be something like
system(attachment.image.url)
I can't figure out how to write the statement to do that.
Your browser will not (and should not) allow you to execute anything outside of the browser itself, this means that without some external app making the call to your Rails app from the clients machine, you will not be able to open the Word doc without downloading it.
You are able to open the images and PDFs in the browser because the browser supports them, but most browsers won't open Word docs.
You can either have the user download the file, or maybe use a third party viewer that you can open the word doc with inside the browser.

Using Firefox 70.0.1 on Arch Linux. (I realize that this question might technically belong on SuperUser, but I suspect that no non-developer would ever need to do this.)
I'm trying to debug my code that generates an RSS feed, by viewing it directly in Firefox's XML viewer.
When I enter a feed URL, like https://en.blog.wordpress.com/feed/, Firefox pops up the dialog that asks me what to do with the file. It calls it an "RSS Summary", and I can choose to open it or save it to disk.
I can choose to open it in Firefox, but then the file is first downloaded to disk, and then opened from a file:// URL. The result is that I can't hit F5 to refresh it; I have to enter the URL anew.
This only happens if the Content-Type header is application/rss+xml. A file served up as plain application/xml (like e.g. https://xkcd.com/rss.xml uses) is opened directly.
How can I tell Firefox that application/rss+xml should receive the same treatment and just be viewed as a regular XML file?
Add the „view-source:“ prefix in front of your url as said in this article: https://css-tricks.com/snippets/html/view-source-of-rss-feed-in-firefox/
You should be able to achieve this using an extension.
There is Open in Browser which seems to resolve the issue.
When you try opening the RSS URL with the extension installed, you will be shown a window where you can choose which action to take. You can choose to open the file as XML in the browser window. If you want to be able to hit F5 and reload the file, you may also want to tick "Do this automatically for files like this from now on".
Note that I haven't read the source code of the extension so I don't know if it is safe to use or not.
My application downloads a PDF and stores it in the LocalState folder for my Windows 8 app.
I have a link within the app that I would like to show the PDF when the user clicks it.
I've tried displaying it using ms-appdata:///local/pdfs/filename.pdf in a window.open call and I also tried using the InAppBrowser plugin within cordova with no luck. Additionally, I've tried the following:
var uri = new Windows.Foundation.Uri('ms-appdata:///local/pdfs/filename.pdf');
var file = Windows.Storage.StorageFile.getFileFromApplicationUriAsync(uri);
Windows.System.Launcher.launchFileAsync(file).done();
I know the file exists as I'm getting a file result back. Just not sure how to allow the user to view it.
By design, the local appdata folder on Windows is accessible only to that app, or to full-trust desktop applications (and this is probably true of similar sandboxed locations on other platforms). As a result, a Windows Store app that gets launched with Launcher.launchFileAsync won't be able access that location (nor can a webview process, which is also sandboxed). If a desktop application gets launched, on the other hand, it probably can access the file, but you can't tell ahead of time if that's the case. Bottom line is that local appdata isn't a good location for letting other apps get at the file.
You'll need to save the file in another location that is accessible to other apps. There are two approaches here, both of which will require a little user interaction to select a location, so they can place the PDFs anywhere they want:
Have the user select a save folder for your app, which they can do once. You would invoke the FolderPicker for this purpose, and save the selected folder in the FutureAccessList. This way you can have the user select the save folder, which grants you consent to save there, and by saving it in the FutureAccessList you can retrieve it in subsequent sessions without having to ask the user again. Refer to the File Picker Sample and the File Access Sample for more.
Have the user select a save location for each individual file, using the FilePicker (see the same sample), and you can also use the access cache to save permissions to those individual locations if you need them later.
There might be Cordova plugins that work with these APIs too, but I haven't checked. Either way, once the file is in an accessible location, launching the file should work just fine.
As an alternate solution, you could consider rendering the PDFs directly in your app. Windows has an API for this in Windows.Data.Pdf, with an associated sample. There might be a plugin or other JS libraries that could also work for this.
I want to programmatically open Excel files on a user's computer, read what is in the first cell, then save this to a mysql db on my webapp with the following info:
cell content (text)
file_updated_date (date)
Is this possible?
Will the user have to install a desktop application for me to open files on their computer, or can I get permission to run a script and return information from a website?
What language or technologies are available to open Excel files, read content, and send to an http endpoint? Is this a Ruby program?
RailsCast is going to be your friend. Learn it, like it, love it. That link should take your straight to his CSV/Excel importing video that can walk you through basically exactly what you're trying to do. As far as reading from the file goes anyways. As for writing back to the webserver, if the webserver doesn't move you can embed the address into your code and work from that. HTTPClient should be able to help you with that part.
I'm using MooTools as JS-Framework.
When a user clicks the "Show Report"-Button on my website I'm starting Request.HTML to retrieve the path of the requested report.
If the report does not exists yet, its been created on the server (a waiting popup is shown to the user). The report file is saved to a special path on the server and this path is returned to the browser.
After I got the path to the Report-File - the Report can reach about 5 to 8MB - I want to show the user a "Download-ProgressBar" while starting a new Request.HTML to retrieve the big report file.
Everthing until this point works fine. I got the ProgressBar filling up, after its finished I got my big file.
But my problem is now, how I can start something like "Open File" or "Save File As" from JavaScript.
I got the freaking file downloaded and shown in the console but now I want the user to save this file somewhere or to open it directly...
Kind Regard.
Why don't just show a link to that file so that it opens in a new page?
That way one can open in a new window and save from the browser's menu (or use the right click>save to menu).
Since you already have your file serialized most browsers nowadays supports the data uri scheme so if this fine to support a limited subset of browsers you can do
window.open(fileToSave, '_blank');
notably old version of IE don't support all kind of files using data-uri so it will not work for html.
There are some File API in newer browser too, and there are some other solutions involving flash but historically the right way to do this is to navigate to a server page which returns an header
Content-Disposition: attachment; filename=yourfilename.html
that will work in any browser (I used this a lot in IE6 with no particular problem).
Is there a way to open an attachment for a TFS work item by double clicking on it (or rather just opening it from the IDE) in your computer's default image viewer, rather than opening it in a web browser? I'd love to be able to change this setting (if it is a setting).
Edit: after reviewing Kate Gregory's response, I looked into this option and realized that the trouble is that VS is launching a url (a handler file to respond with the attachment), which results in the default web browser being launched. A potential work around i'm considering is writing a custom mapper for all web based calls (as in, when going to start->run and enter a URL) that the mapper would determine what kind of call it is (TFS, etc) and use an appropriate program, based on the MIME type responded with, with a second phase to be incorporate this as a VS add-in.
I'm reasonably sure VS just uses your default program. Word for .doc files, IE for .htm files, and (in your case I bet) IE for .jpg files. Try changing the default program you're using in Windows and see what happens.
All files saved in TFS are saved in a path that starts with the following address:
http ://{YourServerName}TFS01:8080/tfs/.../.../...&FileName={YourFileName}.{YourExt}
This means that all files are opened using the default program defined for HTTP protocol, regardless of the extension for your file.
You can probably change the default program for your HTTP protocol (if you have permissions, and usually you wouldn't) but this would also affect opening any regular web page or URL, which is probably not recommended.
I still haven't found a workaround this issue too.
Some kind of preview function in VST/Team Explorer would be nice. Then, only a minor of attachments must be opened in the browser.
