I would like to know if it is possible to open a directory from intranet MVC application ? I have been searching about it but i don't found anything.
I tried to open from javascript using window.open('url') but i get unauthorized access.
Thanks,
Tiago Mourão
IMPOSSIBLE !!!
web browsers does not have allow web pages to access to disk drives.
web pages only can read/write cookies.
FileUpload control allow access to the files, only with user action(scripts no allowed).
I found a way to do resolve this problem. If you create a background process using Process.Start('location'), the application opens directory folder.
Tips:
Process.Start() generally used in windows application and if used in
web applications, a process will start on server(not on user agent
that run current page).
you get unauthorized access error, because of IUser has limited
access ...
1) Web Applications can read/write any file and folders on server side with assigning permission.
2) WebApplication with Some sideway can access to file & folders in web pages (client side) !!!
with JavaScripts:
Write a browser add-on with requested functionality, then install on
user agent(browser).
now with call method/function in add-on, you can do the operations
that does not allowed with JavaScript & etc.
with VBScript(Obsoleted) that run/supported only in MsIE:
can using FileSystemObject to full access files and folders.
can using CreateObject to create instance of each object in OS and
working with it.
Finally my answer is IMPOSSIBLE.

I'm developing a web application using MVC which is hosted in web server. Whenever a user accesses the application, it has to fetch the local app data folder from the clients machine.
Is there any possible way to achieve the above mentioned scenario?
I have tried using Environment.Specialfolder, but it is giving the path of web servers local data not the path of client's machine
C# :
string s = Environment.GetFolderPath(
Environment.SpecialFolder.LocalApplicationData);
Server-side code cannot just access files on client's machine. Instead, this functionality should be implemented with client-side scripts.
If you need to let your app persist some data or file on user's machine, and later read that data and send it to the server (or use it on the client), you have plenty of options in the modern browsers:
Cookies
localStorge
IndexedDB
fileSystem API, though it's not part of the standard, so be careful
Fetching an arbitrary file from user's machine is a totally different story, because it has security implications. Here your options are:
Put <input type="file"> on a page and let the user pick a file that will be uploaded to the server.
Use HTML Drag & Drop to let user drag a file onto your page
Develop an accompanying desktop application, which the users will have to install on their machines.
You may also explore the possibility of developing a browser extension, though this will give you very limited access to user's file system, AFAIK. Today the major standards are Web Extensions for mainstream browsers, and Browser Helper Objects for Internet Explorer.
I recently hosted a MVC application on machine and in solution I have a folder UploadedDocuments which i wants to secure. Actually when i browse URL like www.xyz.com/UploadedDocument it lists all the file even i didn't login to website
Note: Using Microsoft Interop for PDF conversion of docs in this directory.
wants to restrict the users who can browse folder but if a url with file name in folder and a user on website that is loggedin can access only with specified url
like www.xyz.com/UploadedDocument/abc.docx(except www.xyz.com/UploadedDocument)
thanks in advance!
In IIS, ensure that directory browsing is disabled.
On the file system, remove read access for any "normal" user accounts or groups, and have only the app pool account that IIS is running under with modify access to the folder (ie the "iis apppool\[MyApplication]" account).
You say you're using Microsoft interop for conversion. Is the conversion happening within the MVC application, or do you have another application / service performing the conversion? If the latter, also ensure that whatever account is running the other application / service has access to modify the folder.
how can i get a list of folders from a website?
Namely I wrote a program that take a URL
And give a list of folders from the website.
I try
Directory.GetDirectories(myURL)
but it not work.
Generally, you will have to have the server run some code to get the list of directories. The client does not have access to the filesystem of the web server, and even using FTP or WebDAV the scope of what can be seen by the client will be limited.
The easiest way would be to create a folders.txt file in every directory on your web server with the name of all child directories. Then use your favorite HTTP API to download the file and parse its contents.
As for websites that are beyond your control: you can't. However you can check if you have access to a folder with a specific name. That should give you some ideas.
You can't directly access the file system on the web server (a .NET security feature). You can however do this when you're running locally (under localhost), but I understand that's not the point. If you're talking about submitting an URL that you don't own, then typically, no, that's not possible.
I am trying to find ways, by which a user can open a folder on web-server on button click in a web application, based on windows authentication and no impersonation.
Two methods, that i have came across are :
Using href link, it works, but only in IE.
Open "
Using C#, It doesn't seem to work, i gave permissions to Application Pool and Users to access the folder, but was getting access denied.
System.Diagnostics.Process.Start(#"\\test\c$\xyz");
Starting with "accessing to administrative shares isn't a good idea", if your users attempts to access to it as normal user (i.e. probably not logged/verified by a domain controller) will surely fails.
Assuming you want to access to a granted share you should link using file: as URI scheme.
Local folder:
click me
Remote folder:
click me
here works both with IE and FF.

How to open a windows folder when clicking on some link on a HTML page using Python
To begin with, I developed a web application which reads an XML file from specific location and displays the contents on editable web page of the application,which is executed perfectly when the XML file is on the same machine/computer. When I try to read the same file on different computer on the network I cannot read the contents onto my web page.
My Observation:
When I access that file from run window in the computer by entering \xxx.xxx.xx.xx\c$ it gives me the window to connect to the machine asking for credentials and I guess the session is open. So I close the window and when I access the xml file from the web application it's able to read the content.
Is there a way to bypass this authentication mechanism which is part of windows when I use my web app to read the XML file or is there a way to accommodate the extra step to configure the authentication in my application?
I would be glad if someone can guide me to the solution.
Check the user your web application is running under and if this user is also permitted to access this location.
If you are using IIS to host the page you have to check the "AppPool" user and also the users which are used at the "Web Site" and "Application"
Just change IIS application pool user to "enough rights" user (right click current app pool - advanced settings - identity) or specify impersonation in the same name section in web.config.
Could it be possible to change your logic,
By storing file from different network to local machine where your code is running, through uploading file and process it.
