Can't Connect To Database Using Visual Studio
Mar 26, 2008
I can't connect to a SQL Server 2000 database using Visual Studio 2008. When I try to create a SqlDataSource in Visual Studio the db server isn't in the dialog box. When I manually create a connection string it doesn't connect.
When I go to the server, the db is running and apps that use it work fine. I can ping the server, and I can map a drive to it, but I just can't connect to the database. I tried using servername,port - didn't work.
I open SQL Server 2005 Management Studio and try to connect. In the Connect to Server dialog box, when I go to the Server Name dropdown and browse for my database server on the network, the server is not in the list. I tried entering the server name (and password, etc) but it doesn't connect. A different SQL Server 2000 database server does show up there.

Hello,
I have visual studio 2005 installed on my PC. I want to create a new website and I want the site to be connected to a MS SQL 2005 database that resides on my hosting account. I am thinking this can be done but I have watched videos, spent time looking for a site to help and I have hit a brick wall.
I have no idea how to do this.
Can anyone please help me with some instructions or a webpage that shows you how to do this.
Thank You
Joe

I'm right-clicking on Data Connections in Server Explorer, and selecting Create New SQL Server Database. I've turned on the SQL Browser, so I'm able to select the instance from the combo box. I select Use Windows Authentication, type the database name to create, and click OK.
I'm getting this error:
"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)"
I've followed the instructions here, but with no luck:

Is there something else I need to do?
Thanks,

Hi all,
Tried this for the first time this morning using a SQLDataSource and received the message:
"Database schema could not be retreived for this connection. Please make sure the connection settings are correct and that the database is online. This server version is not supported. You must have Microsoft SQL Server 2000 and later"
If possible, how can I connect to the SQL Server 7 as I have a small project to complee and all the data and tables exist on our SQL Server 7 installation.
Thanks for any pointers
Michael

Good day. I was able to connect to a database server using SQL ServerEnterprise Manager. The Server name specified on the tree isJOMARGON(Windows NT). But no server was detected using either VisualStudio .NET and SQL Server's query analyzer.I highlighted one database (master) on the SQL Server EnterpriseManager and chose 'SQL Query Analyzer' under the 'Tools' menu. Itworked. The Title of the Query Analyzer window isSQL Server Analyzer - [Query- JOMARGON.master.JOMARGONJM Gonzalezand below on the status bar, I can seeJOMARGON(8.0) and JOMARGONJM Gonzalez(52)But again, I cannot connect manually using Query Analyzer as nothing islisted in the SQL Server drop-down listThanks

Hi,I am a newbie at all this, but here's what I want to do: We have avery large database sitting on a SQL server that is on a remotecomputer. I can access it through remote desktop and browse theEnterprise Manager and the DB.What I am trying to do is create a Visual Studio .Net program thataccesses the DB. Can I use a data adapter to connect to the DB? theSQL server is on the local C drive of the remote computer so it is notweb based.Otherwise I guess I'd have to install VS on the remote computer andcreate the program there.... but I'm guessing, I really need someadvice here.

I'm attempting to connect to a database file through visual studio 2013 Ultimate. The .mdf file is located on my local drive inside the App_Data folder of the project. However when I try to connect to the file it fails and throws an error message (see below).
“The attempt to attach to the database failed with the following information: 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: 50 - Local Database Runtime error occurred. The specified LocalDB instance does not exist.”

I can't connect to LocalDB using Visual Studio for Web Express 2012 or SMSS 2012 in a Windows 8 environment. LocalDB is installed and some things do work, however. The basic error is the very common:
Cannot connect to (LocalDB)v11.0.
ADDITIONAL INFORMATION:
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: 50 - Local Database Runtime error occurred. Error occurred during LocalDB instance startup: SQL Server process failed to start.
In a command window, I can query the state of LocalDB an "info" parameter:
C:Program FilesMicrosoft SQL Server110ToolsBinn>sqlLocalDB info
SportsStore
TestOfLoc
v11.0
The first two are tests created at the command line using sqlLocalDB.I have reinstalled and repaired LocalDB several times with no errors reported.

I know that my problem is in the @DataSource part of the connection string. It works if I use the first two lines (the database file is in the same folder as the code). But not when I use it as above. I think I'm pointing to the wrong place, but I can't figure out the right place to point to. I have SQLServer running on my laptop (I think), so can anyone help me out or maybe give me some example connection strings that you have used? Thanks.

Hi all,I'm having a big problem here. I can't seem to connect to a database of MSSQL Server 2005... Here is what I've did:1. Under the Server Explorer>Data Connections. Right click and choose "Add Connection..."2. Data Source was "Microsoft SQL Server Database File". Click OK.3. I browse to the database in the MSSQL.2/MSSQL/Data folder.4. Click on the "Advanced" button, and change the default DataSource from .SQLEXPRESS to .MSSQLSERVER. Click OK5. Received this error: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 setting SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid) Only .SQEXPRESS that I was able to connect to... i've tried the solution from Microsoft, opened SQL Server 2005 Surface Area Configuration and enabled "Local and remote connections", checked the option "Using both TCP/IP and named pipes" but it didn't help. This is frustrating because I can't get the Membership provider, login to work on my host. Please help. Thank you very much,Kenny.

Please help.

Hello,
I'm using Microsoft Visual Studio to remotely connect to my database for the project I am working on.
I always get the same error, when I try to connect:
Code Snippet
An error has occurred while establishing a connection to the server.
When connecting to the 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 the SQL Server)
So, I decided to ping the server to see if any packets were being sent back to me, on the command prompt.
4 of my packets were sent to the server.
0 were sent back.
Code Snippet
Pinging sq15.bravehost.com [172.16.0.229] with 32 bytes of data
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping statistics for 172.16.0.229:
Packets: Sent = 4, Recieved = 0, Lost = 4 (100% loss),
So, does the database not allow incoming connections, or am I missing something?
Thanks for the help in advance,
Dustin.

I have a database in my "App_Data" folder of my visual studio project. I can view it fine in Visual Studio's built-in tools for managing a database attached to a solution. However i recently started playing around with the SQL Server Management Studio Express program. When i attach my database to Management Studio, and try to run my program it crashes. I think it might be a permissions error?!? When i detatch it and reattach it in visual studio it runs fine again. Any suggestions? ThanksJason

Hi,
I have VS Pro 2005 and SQL Server Express 2005 installed on an XP Pro machine. When using VS 2005, in the 'Server Explorer' window I can see and attach to two SQL Server databases that I have set-up. But if I attempt to access the same databases from withn the 'Solution Explorer' window I get the following dialog box message,
"
Required Component Missing (Dialog box heading)
Connections to SQL Server Files (*.mdf) require SQL Server Express to function properly. Please verify the installation of the component or download from the URL: http://go.microsoft.com/fwlink/?LinkId=49251
"
I have uninstalled and then reinstalled both VS 2005 and SQL Server Express twice but it has helped.
I don't understand why I'm getting this error because all of the server configuration tools and connection utilities seem to work fine but VS say's that SQL Server Express is not installed.
Thanks,
CLN
P.S.
I had another application that required MSDE 2000A to be installed. When I removed the other application I also removed MSDE 2000A and that's when the problem began.

I'm using Visual Studio 2005 Standard. I have an .mdf database inside my Visual Studio "Server Explorer" under "Data Connections."
How do I script out this database, including the stored procedures in it? In other words, I want to export a SQL script that will create this database.
I'm very much a newbie when it comes to working with database management. I thought I created this .mdf inside my local install of SQL Server 2005 Express, but maybe I did it somehow inside Visual Studio in the Server Explorer. When I open up SQL Server Management Studio Express I don't see this database. I did locate the .mdf on my local C drive but I haven't been able to get Mgt Studio to open it.

I created an SQL database in Visual Studio 2005 Express Edition and would like to edit it in SQL Server Management Studio Express. The only databases listed in the Object Explorer of SQL Server MSE are the system databases (ones that are part of the SQL Server MSE).
If I dig through the directories, I can locate my database under the Visual Studio directory, but I am unable to open it. I get an error message stating, "There is no editor available for [my database]... Make sure the application for the file type (.mdf) is installed."
I'm sure that this is a ridiculously simple rookie mistake that I'm committing somehow, but I'm stumped. Any idea what I'm doing wrong?

mySqlQuery = "SELECT c_name FROM database WHERE c_user='demo'";
//connect to the databasestrCnn = "Data Source=" + connectionServer + "; Initial Catalog=" + connectionDatabase + "; user id=" + connectionUserID + "; password=" + connectionPassword + "; Integrated Security=false";cnn = new SqlConnection(strCnn);

cnn.Open();MessageBox.Show("Success Opening the Database");
}

Hi
I keep reading it's possible to add, amend ,etc. tables in visual studio but to do so I need access to the features that allow this.
I can connect to the database but I haven't been able to use any of these database features since they are "blanked" out.
Obviously, I can do all this at the server but ideally I would like to do it remotely.
Any suggestions?
Thanks in advance.

Any tips?

I receive the following error when trying to add a local database to my project.
"The data provider required to connect to the local data file could not found. The file will be added to the project but the typed DataSet associated with the file will not be generated."
I've reinstalled VS2k8, SQL Compact 3.1 and SQL Compact 3.5 on my machine and still receive the error.
Does anyone have any suggestions? I saw another similar thread about this in the VB2k8Express forum, but there were no helpful answers there. (for the curious: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2769854&SiteID=1)
I haven't used the SSCE before and so it's possible I've mistakenly omitted some required items.
Any help is greatly appreciated.
