I have a Air/Flex desktop application and I'm trying to create a component within the app that can view files on the web server is is already connected to. It just needs to access one particular folder that will contain PDFs, Images & Word documents. I also want the ability to click on the files and having them open in their default desktop applications.
Is this possible and how would I go about doing this?
It's possible but not with your Flex/AIR app alone. It cannot view files/directories on server by itself but it can communicate with your server via webservices, AMF, or any other back end based service. Typically the back end reads the folder and send this information to your app. Your app can open those files in corresponding app but only if those files are available on disk so your app will have to download them prior to opening them.
Every Application has different needs but I myself usually save anything to a desktop or you can use the App storage container as well. As I use only the desktop I download what is needed OR been asked for, and the visitor has the choice of keeping it or if not needed it gets automatically deleted! this way you can use whatever PDFs, Word, Images etc. use read and write (re-write) as well as creating PDFs on the fly with Images, text etc, and that way a visitor also can print directly at his or her own leisure. regards aktell

I am working on a windows store app, one of the workflows within the app would allow the user to export a report in html format. The html report relies on a css file so I would like to ensure that the install process could deploy the file in a local folder. If not I would need to read out the file from the assets folder (within the install bundle) and manually write it out but that seems pretty kludgy
https://learn.microsoft.com/en-us/uwp/api/Windows.Storage.KnownFolders?view=winrt-22000
mentions that "The Documents library is not intended for general use." so would require use through file picker but I would prefer to be able to export the document without user intervention without additional store approval headaches (apparently adding Documents library capability to manifest requires additional Microsoft store approval).
Questions
When I create files within the store app it seems the location options are limited and I can only write to Localfolder (which is actually hidden and users cannot easily get to it) - There must be a way to create a file within the MyDocuments directory that is easily accessible by users but looks like that is off limits to a windows store app? So what is the best approach to write reports to storage that can be easily accessed by users
How can one deploy files to a specific directory during install time? Assuming there are some installer commands/manifest directives that would allow this capability?
Or maybe there is a entirely different mechanism to allow for this functionality within the store app and I am just looking in all the wrong places...
My requirement is to show a panel where I list the local system directory, from where I drag and drop the files inorder to perform operations on it.
In HTML5 the FileSystem API is available , but most of the browsers are not supporting.
Is it possible by using input type as file? Like we browse and select a directory, then we can see the list of files and their details?
As the previous commenters correctly noted, this is not possible because it is considered a security hole. Think about a malicious script that could read out everything on your local file system just by visiting a web page.
You can however implement file drag-and-drop like this: https://github.com/moxiecode/plupload
I'm developing a Chrome application where I want to do basic stuff with currently downloaded files(mostly I want to move them to a new location using an application or extension whichever is possible).
I'm able to get access to the image, audio, video file using the mediaGallery API of Chrome apps. Is there a possible way I can get access to and being able to move other format file from their current location to some other location using Chromium apps?
You certainly read the contents of any directory that the user has given you access to. And, once the user has done this, you can retain the entry so on subsequent executions you don't have to keep asking the user to select the directory. Then, once you have a file, you can use the file API to manipulate it.
This is in principle all the media API does, except that it comes with knowledge of some built-in media directories.
I need to show the server uploaded files in flex 4.5 for a web application to manage the uploaded files like upload, delete and open for preview.
Can anyone help me How to list the sever side files in Flex action script3.0?
You can't just let Flash player browse your server files. But you could create a workaround.
Make a script on the server which will give you the list of files located at the path you're looking for. Through basic POST you can ask for a list of files for a directory. Then you can display it in your flash side. But remember every actual action that happens to your files MUST happen on the serverside. Also BEWARE such things, because it's really easy to look up network requests that are made in browser, so you may end up with all of your files deleted one day. So make sure you implement some security stuff.
I have a java swing based UI which I use to monitor a filesystem folder. Anytime a new file is added to the folder, i upload it onto my web server.
I'd like to drop the java interface and go for a web app with a simple file uploader UI where the user can see the files being upoaded and which were uploaded.
The workflow;
User open browser. Opens the web app page. Browses and selects the local filesystem folder which needs to be monitored. Over the hours as the new files are added to the local folder, they are shown in the web interface and get uploaded onto the server.
My question is what all technologies can i use to implement this. I already have the HTMl based web Ui ready. I now need to monitor(/sync?) a selected local folder. what all do i need to do that. I remember there was something created by google which allowed a background process to monitor folders.
regards
To my knowledge I do not think its possible from the browser because of security concerns. You'll need to rely on client software. You could provide your Java app as a software, similar to Dropbox.
