I have SQL Server 2005 SP4 Express, when I try to establish connection from VS2010 to my database, I get a error:
You don't have permission to open this file
Contact the file owner or an administrator to obtain permission.
I am using windows authentication and I am the only user.
Please help me out to overcome this error.
Also sometimes, it shows file is already open
First of all close visual studio. Now open visual studio run as administrator.
If it not solved your problem then open sql server management studio and follow the steps.
Expand your database.
Right click on your database and choose properties option.
A pop is open, select option menu reside on left side.
Make auto close option true situated in automatic pane.
I am sure your problem is solved now.....

When I try to create an Sql Server Database in the App_Data folder of my Visual Studio 2010 project, I get the following error:
Login failed for user:[Domain]\[user]
I am able to create databases using Sql Server Management Studio. I am using Sql Server Express 2008.
Any help regarding this is appreciated. Thanks in advance!
As you are using express edition, in Visual Studio go to Tools>Options>Database Tools>Data Connections.
Remove the SQL Server Instance Name and click OK.
Now try connection to the server using Server Explorer. Once you get connected, you will be able to create a new DB in App_Data folder.
Here is the connection string:
public string ConStr = "Data Source=.;AttachDbFilename=|DataDirectory|CodeDB.mdf;
Integrated Security=True;User Instance=True";
Also make sure that you have user instances for your DB enabled.
In Visual Studio 2013:
Go to Tools-->> Options-->>Database Tools-->>Data Connections. SQL Server Instance Name
Type ProjectsV12
Then Create SQL Server Database inside the App_Folder, and it will work.
Open CommandPrompt as administrator
Type sqllocaldb info and press enter
It will display all the available local db.
I have connected with the database successfully by using wizard in server explorer. but the data source is showing nothing. i have googled and search on msdn help. but not get help.
I want to add data source. but add new data source option is disabled for me.
I am using windows form application...
I want ask that am i doing right. could you please tell me how can i get rid of not showing thing.
PLEASE HELP!!!
The Server Explorer of Visual Studio 2010 and the Datasource of your application are completely different. Check the following links to see how you can connect your Windows Form Application with Sql-Server database:

I've created a SQL 2008 database project in Visual Studio 2010. I have imported existing tables and stored procedures using both of the available methods of import (script or connecting to db). Regardless of which method I use, after the import completes I see my table files in the Visual Studio project, however, I get the following error when trying to view the object by double clicking on it:
Object reference not set to an instance of an object.
I can also see the files I am trying to access on the hard drive. Perhaps this is a permissions issue masked with an obscure error message? I've done some research and am stumped at this point. Any assistance is greatly appreciated.

Starting VS 2010 with "devenv /ResetSkipPkgs", should help, mostly due to the "non-loading problem" of some of the key modules.
I've been looking around to find an answer to this question, and seeing lots of different answers, some of which don't look right to me. Here's my problem.
I've created a SQL Server 2008 Express database, and populated it with tables from 2 regular SQL Server databases (it's to receive data from the 2 databases). I've done this using Windows Authentication.
Now I want to test deploying an app, as a ClickOnce application, so I've written a bare-bones console app in VS 2010. Next I tried to add a new data source to the SQL Express 2008 database. But when I try to do that I get a message saying, "This file is in use. Enter a new name of close the file that's open in another program." (I'm running VS 2010 as an administrator on my Windows 7 Ultimate box, which was one of the answers someone gave to fix this problem, but isn't working for me.) I don't have the SQL Express db open in SSMS or anything else. One solution I've read is to get into SSMS and detach the .mdf, but then how would I do maintenance, like create new SP's, views, etc? Is it a maintenance nightmare of attaching in SSMS while not in VS 2010, do DBA work, then detach the DB, get into VS 2010 do work, etc?
The database is meant to run on the user's machine; not a network share.
