I need help. I'm trying to create a multiplatform mobile application. One of the functionalities is a local file browser that will allow user to select a directory and create a list of file in this directory. I've already spent couple of hours on that issue and I can not find any solution for that.
I've checked http://ngcordova.com/docs/plugins/file/
But if I understand it correctly it is used when I already have a file, it not allows user to pick the directory.
I don't need anything fancy, it should as simple as possible
The Cordova FileSystem plugin (and ngCordova's wrapper) provide the ability the read directories from the file system. They do not provide any UI, so you would use the plugin to ask for a list of directories and then render it as you see fit. (A UL, a table, whatever.) To "browse" you could use a click handler on the list of directories such that when clicked, you then get the files/subdirectories of that folder. Again, the FS plugin adds support for doing that.

I've created flutter app that opens files of specific types (documents of variouos formats). Currently my app provides its own file browser, so one can select a document there and open it.
But is it possible to assign my app as the default action when clicking documents at any other file manager? Of course I need to perform this settings' adjustment right from my app.
Is it possible?
I cannot find any information on it.
Thanks in advance.
This is what you need: https://flutter.dev/docs/get-started/flutter-for/android-devs#how-do-i-handle-incoming-intents-from-external-applications-in-flutter
Also, take a look at how this is done in pure Android. You will need to change Android code, flutter can't handle this himself. https://stackoverflow.com/a/5097734/3222189
The Chrome Apps API has the very useful FileSystem API which allows a user to select a file for an app to edit (read and write changes to). However, with the entire Apps API soon to be removed, what other ways exists to edit a file on the local file system?
This is not an opinion-based question, I am asking for all conceivable alternatives.
Per https://developers.chrome.com/apps/migration:
Q: My app uses the chrome.fileSystem API to read and write user-specified files and / or directories. Can this be done on the open web?
A: In general, no. The open web can read single files that the user opens, but cannot retain access to those files, write to those files, or have any access to directories.
If it is critical for your app to read and write directories (e.g. it is a text editor with a folder view), you will need to either have a native helper app and extension combo, or create a native app.
I am currently trying to download a small binary file from the web, in order to upload that to another website, both using the API.
Previous versions seemed to have the "file" API module for such purposes, but I can't see anything similar as of the latest (1.14).
The file to be downloaded would be saved in some form of cache (browser cache, preferably), its path stored somewhere, to be then uploaded to another URL via POST.
How would I go about it, when the process should happen completely in the background?
I checked out the how to download a file page, but can't figure out where to download.
Is there a variable URI for the "Downloads" directory, and does a regular Add-On has write privileges in it?.
This is important, because the add-on must be able to function properly on various platforms.
You can use the pref, browser.download.lastDir, which should work for windows/mac as it will be saved in the OS format. However the pref may not always be set if the person has never downloaded anything before. In that case you'll have to build the directory yourself.
var dir = require("sdk/preferences/service").get('browser.download.lastDir');
To build the directory yourself you're going to have to go a little deeper. Check this article on MDN about File I/O which has examples. The DfltDwnld key should give you the directory you want.
Your add-on will have write permissions to everything Firefox has write permission to.
I am to create a new design (CSS & HTML) for a web site which is created using Interwoven ContentCenter Professional.
Now, I can see the existing files in CMS (Interwoven) but, I can't make changes. My changes are displayed only when I'm in edit mode. Nothing in the live page. I tried to submit, create editions of files but still no good.
How should I create or edit pages in Interwoven CMS?
Thanks.
If you're talking about generic pages, then once you are finished you have to click on the Generate option, then choose a directory and click Finish. Last thing you should do is to choose yeswhen it asks you to Re-generate the page.
What you are trying to do is just creating a new file, not generating a file from TeamSite's Formpublisher. It is just like if you are in Windows Explorer and creating a new file. In order to generate a file from a form entry, you need to be in the templatedata directory, ex: /default/main/branch1/WORKAREA/wa1/templatedata/category/type(on unix) or Y:/default/main/branch1/WORKAREA/wa1/templatedata/category/type (on Windows). There should be a file call datacapture.cfg there. There is another directory called data under the above path which stores your data content record (dcr) that are created from the form. This is the file that you can use to generate which will use the (tpl) file under the presentation directory.
How do you distribute other files needed by your application that aren't in a jar file? For example, the application at http://www.javabeginner.com/java-swing/java-swing-shuffle-game . The download contains Shuffle.jar, Shuffle.bat, Score.dat, and an images folder with 3 images in it. I can see possibly putting the images directly in Shuffle.jar, but you wouldn't want to put Score.dat in the jar file because it changes. Is there somewhere you could identify this type of file in the jnlp?
The non-java files should be stored as resources. For files that change, you store the original or template file also as a resource in your jar. When the program starts, you have it check the local system to see if that file exists. If not, it creates the local file by copying the template file from the JAR resource. If the file already exists, then it is used as is.
To save files to the local system, even when running in the sandbox (unsigned), you can use the PersistenceService (javadoc / example). If your java application is signed, then you can use the regular File apis to write the file to the local machine, such as in a ".yourgame" subfolder under the user's home folder.
You can put all those files (except the scores file) in your jar file and load the contents using resource loading.
I've just deleted and restarted my reply twice now, changing my answer each time; this is confusing and needs a bit more clarification.
Are you SURE that application is supposed to be a Web Start app? On the site you linked to, it doesn't appear to be. Are you trying to take an application that was not designed as a Web Start application and change it into one that can be Web Start?
If it's not a Web Start app as your tag implies, then this question is open ended. You can distribute it 100 different ways.
If you are indeed trying to convert it into a Web Start app, you can start by packaging the images into the jar and that will alleviate your first headache if you just read them from there instead of from a File(). If it's going to be Web Start, then you need to decide how you want to keep scores. You have to decide what the scoring system is like before you can decide on how to go about it; will all the scores be kept on the web site hosting the Web Start app? Will that part still be local? If you want to get access to the local file system, you need to sign the jar, then you can extract the score.dat to the file system and do whatever you want with it if the end user accepts.
You need to figure out what you want to do before you can do it, or at least clear it up for us if you already know more than we know you know.
