I'm using VB 2008 Express for our College Project. I'm also running SQL Server 2008 Express and have installed SQL Server Management Studio and used it to create my database.
Both software have been installed and running locally. I'm trying to connect to the database from VB 2008 Express. Database connection wizard have 3 options:
connecting to Access db
connecting to SQL Server 3.5 compact db and
connecting to SQL Server db file.
There are no problems connecting to the first two but when I try to connect to my SQL server DB file (.mdf) it throws the following error ("Unable to open the physical file .... Operating system error 32:(failed to retrieve text for this error. reason:1815.......an attempt to attach an auto-named database for file ...... .mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share")
I appreciate if anyone who had the same experience and overcome the problem could point me in the right direction.
Thanks very much.

You need to detach your database from the server. Since you created the file there it is already running on the SQL Express server. Operating System Error 32 is a sharing violation and it means that the file is in use.
Try this:
Open Sql Express 2008 Managment Studio and find your database in the Object Explorer tree.
Right click on your database, choose tasks, and then select "Detach"
When the "Detach Database" dialog appears, select the checkbox that says "Drop Connections"
Click ok.
Your database should detach from the database server. Now the server will no longer bring that database up automatically and you should be able to get exclusive access to it.
Note that if you want to make more edits to the MDF you will have to reattach the database or you will need to use the tools built into VB 2008 Express. Because of this most people would choose to leave the database attached and not run it as a "User Instance". Check out this link for alternative ways to get to your data: How to: Access and Initialize Server Explorer/Database Explorer.
Anyway, you may have your reasons for setting it up this way. The steps outlined above should fix you up. Good luck with your project!

I am using SQL Server Management Studio 10.5 and I'd like to link an Access file to it. I've been looking for answers over the internet but I didn't find any answers for this version.
I'm stuck at creating a new datasource (which should be the access file, right ?).
Where am I supposed to see the wizard for the creation of the datasource?
Use DB Root tree-> Linked Servers -> Server Objects-> Linked Servers.
Don't forget to create a DSN to access to it from SSMS.
I read another article concerning this problem when getting the file in use message. I went into SQL Management studio and disconnected the database but still no success in connecting. Here's what's happening step by step:
I downloaded SQL Express 2014 and installed it. I created a DB called MyEntertainmentDB, then created a couple of files (Movies and Rating). I added some data to both. I fired up VS and in VB I created a form added various controls including a datagrid. The DB exists in the default location used by MS SQL. I clicked the Smart Tag and the data grid view tasks window appears. I click the choose data source drop down arrow and then add project data source. Database is highlighted and I click next. Dataset is highlighted and I click next. Now I click new connection and select Microsoft SQL Server Database File (Data provider is .NET Framework Data Provider for SQL Server (the only thing in that drop down box)) and I click Continue. Now I'm shown a window that has the data source as Microsoft SQL Server Database File (SqlClient) in the first box and I browse to where my database is located and select it (which is C:\Program Files\Microsoft SQL Server\MSSQL12.SQLEXPRESS\MSSQL\DATA\MyEntertainmentDB.mdf). Everything is going well and I'm using Windows Authentication. I click ok. Now it waits several minutes and I get this message:
The attempt to attach to the database failed with the following message: A network related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 50 - Local Database Runtime error occurred. Cannot create an automatic instance. See the Windows Application event log for error details.
I looked in theSQL Server log but nothing was mentioned shedding any light. I could not find any VS log. I checked the windows logs but could not find anything seemingly relevant. I'm at a loss for this problem and am about ready to trash MS SQL server and just go with MS Access 2010 or MySQL. Does anybody see where I'm going wrong? If so, please help, I've tried to be very specific and hope I've provided all info necessary.
First of all you must configure your MSSQL Express Server to respond.
To do that you must open SQL Server Configuration Manager (on Windows 8.1 just go in the upper right corner, hit Search and type: SQL Server Configuration Manager. If you are using Windows 7 you can find it on Start Menu).
On SQL Config Manager you must go to expand SQL Server Network Configuration and you'll see Protocols for (your DB instance). Click on that.
After you click on Protocols for (your DB instance) in the right window you will see Shared Memory, Named Pipes and TCP/IP. Double click on each and set them to Enabled = Yes.
Now your MSSQL Server must listen to standard port 1433. To do this double click on TCP/IP, select IP Addresses (Now you will see IP1 config, IP2 config, etc), scroll down to IPAll and set TCP Dynamic Ports to 0 and TCP Port to 1433.
Now restart your SQL Server Service. If don't know how to this, just reboot your computer. After reboot open command prompt and type netstat -a to see if your MSSQL is listening on port 1433.
Now in Visual Studio when you are connecting to your SQL Server on Server Name type server IP (your IP or 127.0.0.1) or you can select your SQL Server instance from dropdown list without any problems.
You can check this tutorial too: Allow SQL Server Express to accept remote connections
Alright, I finally solved the problem and not in a way people would think. First off, I want to thank everyone who responded with the intelligent answers, but we were off base on this one and I'm not sure why, but your responses ultimately led to my defeating this problem. I've been wrestling with this problem for the last 3 days almost exclusively - I don't like being beaten - and 1 entire night. I've uninstalled and re-installed several times and even got superstitious and waved a chicken bone - lol - at it but nothing worked! I've asked this question on several web sites and finally I went to a link that stated the .msi file was included with MS SQL Server 2012 Management objects I and was hesitant to download as they pertained to the 2012 version. So after tinkering to no avail I downloaded the 2012 CLR Types and Management Objects and looked in the Windows\assemblies folder and still no v 11. But I guess 2012 installation installed them in Program Files (x86)\Microsoft SQL Server\110\SDK\assemblies\Microsoft.SqlServer.Management.Sdk.Sfc.dll v11.0.2100.60. I ran VS 2013 and added the data source. After going through all this problem I'm wondering why Microsoft invents all these places to put things when one would work. Every version of windows from 3 to present has always been totally revised and I wonder for what. Improvements are okay but quit reinventing the wheel. Without your help I might not have ever found the solution and perhaps would have been an oracle or mysql guru or not. Your the men. Thanks all.
Do not connect to mdf, connect to the SQL Server and use MyEntertainmentDB database from there.
The MDF file is locked by the SQL Server for reading/writing data.
I am getting following error.
Restore failed for Server
I have recently upgraded SQL Server 2005 Express to SQL Server 2008 Express.
I have taken a Backup on Production Server, having SQL Server 2008
Backup was good and I tried restoring Backup on Production Server, that works great.
Than I downloaded that backup file in .Zip format with FileZila Software (And that is good too).
But when I tried to restore that file I am getting following error.
Restore failed for Server
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

Things I tried which didn't worked
Attempt 1
Try to take backup using following command
BACKUP DATABASE go4sharepoint_1384_8481
TO DISK='C:\HostingSpaces\dbname_jun14_2010_new.bak' with FORMAT
And tried restore that file.
Attempt 2
Somebody wrote to test Version of my SQL Server.
When I tried to run following command in SQL Server 2008
Select ##Version
It is giving following output

My Production Database is in SQL Server 2008, and I am trying to restore DB in SQL Server 2008 but above version is showing as if i am using SQL Server 2005.
Any idea how can I restore SQL Server 2008 DB.
Many Thanks.
Is it possible that, instead of upgrading your 2005 instance to 2008, you instead installed 2008 side-by-side with 2005, and you're connecting to your existing 2005 instance? Look for other instances on your machine.
You cannot restore a backup from a higher SQL Server version on a lower version - this has never been able in SQL Server.
If you have a SQL Server 2008 backup, you can only restore that on a SQL Server 2008 (or later) machine - but not on a 2005 box. No trick, no workaround, no way to do it.
You have 2 options here.
Use WITH REPLACE while using the RESTORE command. This will overwrite the existing database and restore the database state represented by the backup files.
Delete the database to which you are trying to restore to and restore again using RESTORE command. This will create a new database with the state represented by the backup files.
Please note that in both these options you will lose the existing data of the database you are trying to restore to.
Make sure it is installed correctly - in your program files\microsoft sql server directory there whould be a 100/150 folder. Check out the install log in setup bootstrap\log.
As described above the reason for this behaviour is that by default SQL Server doesn't allow restoring a database backup to an older version of SQL Server, regardless of the compatibility level of the database the backup was taken from.
You can try to:
Start SQL Server Management Studio and connect to the instance where the database resides
In the database context menu navigate to Tasks | Generate Scripts…. This will invoke the Generate and Publish Scripts wizard
In the Introduction step of the wizard click Next
In the Choose Objects step of the wizard make sure that the Script entire database and all database objects option is selected and click Next
In the Set Scripting options step of the wizard:
Select the Save scripts to a specific location option
Specify whether the database objects and data will be scripted to a single file multiple files, as well as the path and encoding of the generated scripts
Click Advanced
In the Advanced Scripting Options dialog that will appear:
Specify the version of the SQL Server you need the database restored to in the Script for Server Version option
In the Script for Server Version option specify Schema and data
Set the following options to True:
Script Logins
Script Full-Text Indexes
Script Triggers
Click OK
Click Next
In the Summary step of the wizard click Next
In the Save or Publish Scripts step of the wizard click Finish
Execute the generated SQL script(s) against the older SQL instance
Although the procedure listed above should work:
1. It doesn’t migrate all of the database objects (e.g. sequences or queues)
2. It might fail if your database contains dependencies which SQL Server fails to recognize (e.g. dependencies to databases residing on linked servers)
You can take a look at the rest of the article on Solution center. There is also third party tools you can take in consideration.
I installed VS 2008 without SQL 2005, then I installed SQL 2008, then I needed 2005 express so I reinstalled VS checking the SQL feature.
The installation went OK, however I still cannot open mdf files from VS.
I think there is no 2005v instance installed.
When I dbl-click an mdf file in VS I get the following message:
Connections to SQL Server Files (*.mdf) require SQL Server Express 2005 to function properly. Please verify the installation of the component or download from the URL: http:go.microsoft.com/fwlink/?linkID=49251.
Update
I tried to attatch it, it doesn't work.
When I tried to attach it to SQL 2008 it doesn't work, when I try to attach it to SQL inside VS, I get the following error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I suspect that SQL 2005 doesn't have any instance at all.
I opened SS manager and I didn't see any installed instances.
I don't know how to install an instance, or else if there is a way to open with 2008 tell me.
Any help will be really appreciated!
You don't just "open" an mdf file in Visual Studio - you need to "attach" the file to your SQL Server instance, then access it by creating a SQLConnection (System.Data.SQLConnection) from your VS application. See here for more info on attaching databases (note the FOR ATTACH option), and here's a good intro on accessing SQL Server data using a SQLConnection.
Oh, and if you should happen to see anything about "user instances", pretend you didn't. It was supposed to make auto-attaching databases easy (in fact, attaching databases isn't all that hard anyway). Microsoft is warning that the feature will be discontinued in later releases of SQL Server, so you're better off just learning the "right" way to do it.
This kind'a sucks. If I connect to a SQL Server DB (.mdb file) through VS.Net's server explorer, then I can't connect to the same file via SQL Server 2008 Management Studio at the same file. The file is locked.
For example, I get the following error from SQL Server Management Studio
CREATE FILE encountered operating
system error 32(The process cannot
access the file because it is being
used by another process.) while
attempting to open or create the
physical file 'C:\SQL Server 2000
Sample Databases\NORTHWND.MDF'.
(Microsoft SQL Server, Error: 5123)
I'm playing around with LINQ to SQL. So you would need to connect to VS.Net server explorer to drag in your table objects and create the .dbml files. However, if I want to query the database using old school SQL from management studio, I can't... I get the above error. Ditto if I try to connect using LINQPad (great tool...but useless thanks to this irritating file lock).
So does anyone out there know how I can connect to the same .mdb file from multiple programs like VS.Net's server explorer, SQL Server's management studio and LINQPad all at the same time?
Thanks!
By the way, this site is simply awesome and I love the fact that they made it in ASP.Net and used LINQ to SQL for data access... okay, off topic. Sorry.
The sql engine will lock the file once connected to it. nothing prevents you from attaching a file to an instance of SQL server and then connect to it from multiple applications.
The clue is in the name "SQL Server" - its seems that you can't attach the DB to two places which is not entirely unreasonable because you can't serve it twice (given that the server has responsibilities for things like transactions, logs, locking, etc).
So...
You want to "run" the database in an SQL Server instance and then connect from Visual Studio to that instance and then to the file rather than open the file directly (the option is there because it simplifies some deployment models) at which point you should get what you need.
As an aside, its perfectly possible to to "old school SQL" from within Visual Studio - although I'm not aware of an equivalent to LinqPad
