Connecting to SQL Server 2005 Express

I am having major issues connecting to SQL Server 2005 Express from Visual Basic 2005 Express, which I have tried on multiple PCs but to no avail. Can somebody please explain to me what I'm doing wrong?

1) I install SQL Server 2005 Express and Visual Basic 2005 Express (With .NET framework and SQL native client of course)
2) I open SQL Server using Management Studio and going in with windows authentication. It automatically sets the log on name to computername\SQLEXPRESS.
3) I create a new database called Test and add one table to it
4) I go into Visual Basic 2005 and create a new project.
5) I go to the projects application settings (Properties - Settings).
6) I set up a new connection string, choosing SQL server as the conection type and then on the Connection Properties window it asks me to select the mdf file for the database. I choose the file Test.mdf from the directory C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\
7) I click on Test Connection.

When I do this on two out of the three home PCs I get the error:
Unable to open the physical file "C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\Test.mdf".Operating system error 32: "32 (error not found)".
An attempt to attach an auto-named database for file C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\Test.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

The third PC gives me a different error:

Cannot open user default database. Login failed. Login failed for user 'DAVE\David'.

I get the same errors when I try to use a connection string inside the code directly. Does anyone have a clue as to why these errors are occuring? Do I need to set up security or something else on the database first, or is there another reason? If anyone can please help me get to the bottom of this or provide a web address where I can get the answer (step by step instructions on how to connect) then I would be most grateful.

error code 32 means:
"The process cannot access the file because it is being used by another process."

So, either use a different file name for your connection in Visual Basic 2005, or try disconnect your connection in SQL Server using Management Studio.

pse post the Connection string... it seems like u r trying to attach a db called Test....

in the second error .. check what is the Default Database given for user DAVE\David.... the default database should exists and this user should be a user of that db.... for debuggin purpose ... just change the default database of this user to Master and try... it will connect...

Hi, I get the same error as the original poster of this thread. I have no other database with similar name or anything, and i have not, as far as i know, any other connections to this database, since I just created it. Do you have any idea of how I should go about this?

Thanks

Connecting to SQL Server 2005 - Not Allow Remote Connections

I use ASP.NET 2.0 and VS.NET 2005.

I have the following expression in my code:

string connectionString = "server=\'localhost\'; user id=\'sa\'; password=\'\'; Database=\'Northwind\'";

When I executed the code I have the following error message:

"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)."

The Microsoft Access was successfully connected in the Server Explorer window.

How do I solve this problem?

Thanks,

Andy.

Try this thread for the two links you need to get it going. Hope this helps.

From your link, I found the following link http://support.microsoft.com/default.aspx?scid=kb%3bEN-US%3b914277. I have followed all the instructions from that page, but I still receive the same error message.

I am not sure which version of SQL I am using. From the "start" -> "All Programs", I can only see "Microsoft SQL Server". It was installed, when I installed Microsoft Visual Studio 2005 Professional.

Connecting to SQL Server 2005

I have successfully installed SQL Server 2005 on a server that also has SQL
Server 2000. Using SQL Server 2005 interface, how could I connect to a
named instance of a SQL Server 2005 database? As I try, it keeps connecting
me to the SQL Server 2000 db. Is this something you set up in CLient tools?
Please let me know, I connect to the SQL Server using a temp dns name.

Not sure what you're trying, but generally it's servername\instancename. If
not instance name is provided it deafults to the default instance.

Connecting to SQL Server 2005

Hello!
I was wondering if I need to install something on the client in order to
establish ODBC/OLEDB connection to SQL Server 2005. Currently, I have ADO
2.6 installed. Are there any changes in ODBC/OLEDB drivers for SQL Server
2005?
Thanks,
IgorHi
It is best to use MDAC 2.8, but 2.6 will connect to SQL Server 2005, but you
will not be able to use the new datatypes that SQL Server 2005 has
introduced.
The ODBC/OLEDB drivers no longer ship with SQL Server, as it is now a
function of the Operating System to update them.
The new way to connect to SQL Server 2005 is SQL Native Client (SQLNCLI)
"Provider=SQLNCLI"

This is not quite right. MDAC is part of the operating system, but SQL
Native Client is not.
The SQL Native Client is a seperate install. It is included in the SQL
Server distribution and available here:
http://msdn.microsoft.com/data/sqlnative/default.aspx
There are now 3! OleDb providers for SQL Server. Two in MDAC: MSDASQL
(deprecated) and SQLOLEDB (current). Plus one in the SQL Native Client
(SQLNCLI). SQLNCLI is the best, but you must install it.
SQL Native Client also has a new ODBC driver.
David|||David,
I am able to connect to SQL Server 2005 using SQL Native Client but
I got en error 'Server unavailable or access denied ...' when trying to
connect using Microsoft OLE DB provider for SQL Server. I am trying to
connect by setting up properties of UDL file on the same box where SQL
Server is installed. Did I get it right that I have to install latest
drivers on client computers from the link your provided?
Thanks,
Igor

Connecting to sql server 2005

I want to connect to database using sql server 2005 through Visual web developer 2005 express edition . what will be the connection string for this....

keywords under * * are for your own variable.

connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ *datafile name *.mdf;Integrated Security=True;User Instance=True"

if it is a database in a local drive

and if you are using a web server ,

connectionString="data source=*ip address * ;user id=userid;password=pass"

The following link might help you..

In fact that is not the right explanation. The above mentioned syntax is used when you use the SQL Server 2005 Express feature of user instances. The above mentioned sample assumes that yxou have a local SQL Server Express instance (configured with the instance name of SQLEXPRESS). User instances are used to temporary attach datafile to SQL Server instances.

This has nothing to do with a web server. The above mentioned syntax is used when you have a SQL Server attached database. No matter which middle tier (either an application you wrote or a web server is connecting to the database server)=, you are able to have multiple conenctions from multiple applications to this database, other then the user instance where only one application can create a user instance and have access to the database at a time.

Connecting to SQL Server 2005

I installed the SQL Server 2005 Trial and am now having trouble connecting. When I bring up the ASP.NET Configuration tool and Go to "Provider configuration" "Select a single provider for all site management data" AspNetSqlProvider Test I get the following message.

"Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider. "

I have already run the aspnet_regsql command-line utility.

Can anybody give me some information on how to set this up.

I am currently working with the club web site starter kit.

I first recommend you go grab this awesome management tool for the express edts :

http://www.microsoft.com/downloads/details.aspx?familyid=82afbd59-57a4-455e-a2d6-1d4c98d40f6e&displaylang=en

I would then first check to see if your connections to the DB work with this tool and copy the connection strings it gives you and use them in your app. Also, you can configure ASPNETDB from the web.config level and dont have to use the web tool. This way you can test directoly to ASPNETDB. I havent used the club starter kit but im sure it either uses app_data or aspnetdb in the db. All you have to do is point to the right one. I wrote a couple blogs on this :

http://eramseur.blogspot.com/2005/12/aspnet-20-create-custom-provider-for_10.html

I would also check out scotts entry :
http://weblogs.asp.net/scottgu/archive/2006/02/24/438953.aspx

He has another article about how to get membershp up in 15 minutes and you should look at that too.
