Configuration->Security Page Fails To Create AspnetDB.MDF In App_Data Folder On Windows 7
Feb 12, 2010
I am having problems getting the security.aspx to load up on my primary development computer which is using Windows 7 Ultimate and Windows IE 8. Clicking on the ASP.NET Configuration icon from the IDE in the Solution Explorer within Visual Web Developer 2008 Express Edition loads up default.aspx with no problem. But when I click on the "Security" hyperlink to access "security.aspx" I get a message along the lines of "The configured SQL data source provider is not properly configured". It goes on to state a list of potential reasons for this problem. One that includes not having the proper credentials or permissions. Im almost 100% sure it has something to do with permissions because I can't even get to the "security.aspx" page from opening a new empty project. I have recently installed Visual Web Developer 2008 Express Edition on my laptop which is running Vista with all latest updates and this issue does "not" exists. I can click the "ASP.NET" icon, load up "default.aspx" and click "Security" and it loads the page with absolutely no issues.
I have discovered a weird workaround but I don't like having to do this. If I add the following lines to my "web.config" file from any given project I can get to the "security.aspx" page without getting any SQL messages about improper configuration or permissions.
<<remove "LocalSqlServer">
<add
name="LocalSqlServer"
connectionString="data
source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
providerName="System.Data.SqlClient"/>
Basically, what I have to do to get to the security page to load without error is add a remove statement and then I just cut'n'paste almost the exact same connectionString from machine.config in the Microsoft.netFrameWorkV2.0.5027config directory. This does away with the "Improperly configured SQL datasource message" and gets me a new error message along the lines of "Could not create a SQL instance". My memory is fuzzy on exact error messages since Im not at development computer right now. However, when I change the User Instance attribute from true to false, then I have success at last.

I have a few questions regarding the "special" ASP.NET folders in Visual Studio web projects.
Adding an App_Data folder in Visual Studio is present, but grayed out in my C# web project, why?
What are the meanings of the various ASP.NET "special" folders?
App_GlobalResources App_LocalResources App_Data App_Browsers Themes - I know this is used to contain stylesheets for a particular theme and is then specified in the web.config or page (if I remember right).
App_Code - Were these classes that were pre-compiled? Do these ASP.NET folders retain their special meaning if you manually create a folder with the same name instead using the "Add ASP.NET Folder" feature in Visual Studio?

I am trying to add a new database via the App_Data Folder and I receive an error described below.When I attempt to add ANY TYPE OF SQL SERVER DATABASE through the App_Data folder I receive this error "Connections to SQL Server Files (*.mdf) require SQL Server Express 2008 to function properly. Please verify the installation of the component or download
from the URl."
I can create a db via SQL Server Mgmt Studio, it connects fine, and I can see tables.
Visual Studio- Server Explorer connects fine to the Database, I can see the tables.
Im running XP SP3 w/ Visual Studio 2010 and SQL Server 2008 R2 Developer. I had previously removed SQL Server Express.
Why cant I access the database within my project, when Im able to connect to this fine within Visual Studio Server Explorer?

I have secured some files on my webserver by putting them into the App_Data folder in the root (I do not have the option to secure folders using the ASAPI filter)The user gets access to these files by requesting them through a handler, fx. by requesting ~/Handler.ashx?file=App_Data/MySubFolder/MyFile.jpgNow, I want to make all the content in a specific folder called "Members" (a single subdirectory of the App_Data folder) available only by passing a specific password. That is by requesting ~/Handler.ashx?file=App_Data/MySubFolder/MyFile.jpg&password=xxxxIn my Handler.ashx I have written some logic seeking if InStr(context.Request.QueryString("file"), "Members") = 0 before sending the file.If inStr <> 0 a password is required.Is this a good way to secure a folder in and its content? Is there a way of getting access anyway, like using some kind of "sub-directory" line in the path (the same way as you can request parent directory by using "../../Myfile.jpg)? I know there will be a problem if someone fx. legitimately tries to access the file App_Data/Members.jpg

The following code is used to add the asp membership tables to an already existing database instead of creating a seperate database for membership and having two databases in the application.
aspnet_regsql.exe -S .SQLEXPRESS -U username -P password -d databsename -A all
It works fine by adding the membership tables to the existing database that is located in the c drive, program files sqlserver folder.
But my database however is not in the c drive but located in my asp website app_data folder, so the above code does not give any error and the tables are not added after I run it. how can I now add the membership tables using the above code when my database is located in the website app_data folder,

I'm taking Microsoft's walk through on MVC 2 Forms Authentication - [URL]According to the walk through, when I register a user, ASP.NET creates the ASPNETDB.MDF file and it is supposed to show up in my APP_DATA folder upon refreshing in the solution explorer. The problem is, for me it is not and I want to have a look inside so I can understand it's structure.I can continue to run the project and login as the user I created, yet the ASPNETDB.MDF file is still not visible under the APP_DATA folder.

Just to describe the scenario. I have a website. This lives on a webserver. On that webserver is an SQL server. The website connects to this database using windows authentication. I have written a windows form application that connects to the SQL Server on the webserver. This application is being run from a location on out intranet. The Winform application use SQL authentication to connect to the database. The SQL Server didn't have mix mode authentication enabled. So I enabled it. The winform application could now connect to the SQL Server.
This is where it starts getting a little strange.
The Website that was already connecting find using integrated authentication starts failing with:
Login failed for user 'NT AUTHORITYNETWORK SERVICE'
When you are enabling mixed mode authentication, you are adding another authentication method, why would the original Windows authentication fail?

I have installed Visual Web Developer 2008 Express Edition along with SQL Server Express 2008 on Windows Vista and Windows 7. On Windows Vista, when I click the "ASP.Net Configuration" icon in the Solution Explorer and then click on the "Security" link, a new ASPNETDB.MDF file is created in the App_Data folder of any new project I have open. The same actions on my "Windows 7 Ultimate" machine will result in a message along the lines of "Your Data Source is not configured properly. This may be because the server has an invalid name or you do not have the proper credentials or you do not have the proper permissions"(not at Windows 7 machine right now so this isn't verbatim)

I've noticed that ASP.NET automatically creates an App_Data folder for you whenever you make a new webforms application.
Since all of my data comes from a SQL Server 2005 database server, is there any reason to actually keep this folder?

I got an error about asp.net cannot find window emp folder, so I created one and gave the right permission and the problem went away. Three days later same problem happened and I went in and couldn't find my temp folder. This is on a live server so is there a reason for my windows temp folder gone out of the blue? Is it possible that my server host company does some maintenance that cleans up the folder? Also, what is the difference between NT AUTHORITYNETWORK SERVICE and servernameNETWORK SERVICE?

Pardon if this is a very dumb question, but I was trying to migrate an existing ASP application to asp.net MVC, and followed the procedure from the music store tutorial (http://www.asp.net/mvc/tutorials/mvc-music-store-part-4), which involves adding the
database to the App_Data folder. (I had to restart my machine before it would work, since otherwise, Visual Studio thought the database was being used by another application.)
Now when I check in Windows Explorer, it looks like the database file was literally copied into the App_Data folder, and now I have two mdf files on my hard drive with the same name. What is going on there?
Will my MVC app ignore the original (real) database and use it's own private copy instead? (That would be bad.) Or is the new copy just for reference when using wizards that generate entity classes etc.? If the latter, what is the procedure when the real
database is modified, to update the application code?

I have a number of XSLT files in my ASP.NET Web Application solution. Should these go in the App_Data folder?
The MSDN 'Project Folder Structure' article suggests that the App_Data folder is for 'data files'. As XSLT files are not strictly 'data files' then should they go elsewhere?
I do not want end users to be able to access the XSLT files from their browsers, so App_Data seems like an obvious location for this, but I am not sure.

I have put a css file in App_Data folder and referrenced it properly in the page to be used. But when I browse the page then it does get loaded and page is shown without styling. Well I know why it is happening because Asp.Net run time blocks access to App_Data folder at run time. But I wanna ask that how we can make it working that is I put the css file in App_Data folder and it still works.
