Configuration :: How To Read Write Folder Contents Outside Project Folder

May 15, 2010

We store backup archives in subfolders of a folder on one of the server's external USB drive. I would like to have an ASP.NET app read the contents of this folder so the manager can view the backup files to confirm backups are working and optionally delete these backup files when an old drive is reconnected so it can be used for the next weeks backups.

This backup folder is oubviously outside the server's webroot. Is there some way I can grant authority so the ASP.Net app can access this folder for this purpose? I would be using VS Web Express, so can't create any signed packages and such.

Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )

Using System.Data.OleDb;

I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.

Grant Access To Controllers / Views For Non-authenticated Users?

Feb 3, 2011

I have an MVC 3 application which uses asp.net authentication. I have just created a custom errors controller and a couple of views for unknown errors and 404's. This works fine when I am logged into the application but if an internal server error happens during logon I would like to display the error/unknown view. However I just keep getting redirected back to the login as I am not authenticated.

I have added a location path for 'Views/Error' to my Web.config to allow access to all users but I am guessing it's the controller access that is causing the redirection.

Is there any way you can allow this in MVC or do I need to think of another solution? Just did not want to add a generic message to the login page as that's what my unknown error view is for.

DataSource Controls :: Write MVC Application To Access Multiple Data Stores?

Mar 17, 2010

I would like to write an MVC application that accesses multiple data stores (SQL Server, MySQL, Cloud based, etc.).Most of the examples I see use LINQ to SQL for their data access but I read somewhere that LINQ only supports SQL Server - it may have been an old post.I was wondering what the best way to access these different data stores would be. Can I use the Data Access Application Block from MVC to access these data stores?

Outputstream - Can Get Read Access To The HTTP Output Stream In Web Application

Feb 22, 2010

I would like to read all content that's been written to the output stream. I'm attempting to do this using an HTTP module, and it seems like the obvious timing would be when handling the PreSendRequestContent event.

However, if the output stream seems to be set to write-only, as I can't read using a StreamReader. Is there a way I read and re-write the content without writing my own IIS module?

Iis7 - Error On Cache Folder In Application / Access To The Path 'Cachev10' Is Denied

Feb 17, 2011

I'm working on an ASP.NET application that accesses Team Foundation Server 2010 and creates new work items. The application is running in the DefaultAppPool, using NetworkService as the identity. I'm getting the error below:

[UnauthorizedAccessException: Access to the path 'Cachev10' is denied.]


We were able to work around the issue by turning the Cache folder into a network share and giving NetworkService full access to the share. I'd prefer not to have to do this, but it seems to be working correctly now.

Security :: Grant Access To Default Page For All Users - Authenticated & Non-Authenticated?

Aug 18, 2010

I've a default.aspx page in my application's root folder. I added a a page in the root of inetpub that redirects requests to the default page. The idea is that the user need only enter the server name to get to the default page. How can I set things up so that all users have access to the default.aspx and that they only have access to the other pages once they've been authenticated?

I am using Windows Integrated Security and the users are being challenged and authenticated properly. I want them to be able to access Default.aspx without any challenges.

(On a side note which may answer this question, when using WIS does the user *allows* have to be challenged? Isn't it possible to pass through their Windows User and ID without the prompt?)

c: inetpubwwwroot
edirect.aspx (set as default document in IIS and simple executes Response.redirect("sites/mercury/default.aspx")

Access A Namespace Inside App Code Folder From Another Folder

Sep 20, 2010

I have a class file stored in the app code folder. A certain page that I want to access is inside its own folder within the root and it is using the namespace within the class file in the app code folder. How do I tell the application where the file is? I'm sure I could put the code in a file inside my folder, but I'd rather not have duplicate code in two different files... unless there is a way to make a reference of some type.
