I'm new to .NET and while starting to learn ASP .NET MVC2 framework I see that you can create a .mdf file inside the App_Data folder and connect to it or you can connect to a SQL Server.What is the difference between these to methods of interacting with a database? What are the advantages/disadvantages of one over the other?

Is it possibe to write to an Access database in the App_Data folder of a website that lives on a local server using Microsoft Access? And also connect and read with ASP.Net?The internet connection is "Read Only".
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?

View 1 RepliesThe 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 am currently developing a website currently in ASP.NET. I need to give the current ready website to another collaborator to continue with the work. But how do I send the database along with the website?
If this is done, what steps do I need to follow to use the database on the new machine? Do I need to change web.config or what more?
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?
how do i connect visual web developer to sql server express 2008? in the Database Explorer, i right click on Data Connections, click Add Connection..., and in the Data source box i choose Microsoft SQL Server (sqlClient), which i'm guessing doesn't connect me to a database file, but to sql server express itself(?). in the server name box when i click the drop down box, there's nothing there and that's where i get stuck.
View 3 RepliesMy Microsoft Access DB file is in APP_DATA folder. my server is Windows 2003 and I like to know how is the best way to protect this file.

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.

View 2 RepliesI 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 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

View 1 RepliesAs a follow on from this question I'm building a custom server control to be placed on a Sharepoint 2010 master page. The idea behind this is that it will display a menu that is dynamically populated from the database. As this is a server control, I'm building it in a dll but I've run into a small snag. As it has to connect to the database, I need to store the connection string somewhere (and have it able to be configured based on target configuration (dev/test/prod). I was intending to the user the Entity Framework as my ORM but i'm confused as to where the connection string is to be stored. In a normal ASP.NET web app it goes in the web.config, but this is a server control in a external DLL.
Where do I store the connection string so that I can just build and deploy the assembly containing the server control.
EDIT:
Before I post a bounty, I have tried using an embedded resource XML file to hold the connection string and while this works, I'm curious as to if this is best practice/a better way?
I have a project that must illustrate that connection to the database is not locally, so I have install VirtualBox and I intend to install SQL Server on it. So any one have the idea of how can I connect from the Host Machine to the SQL Server located on the Virtual Machine
