Cannot Connect To Locally SQL Server In C#.net 2005 Express
Aug 30, 2006
I am trying to do the Chapter 1 project of Getting Started with ADO.net 2.0 Step by Step (microsoft press)...
I enter the data source configuration wizard and select database, and press next.
I then press the new connection button, and the Choose data source screen appears.
In the List are only 2 options:
Microsoft Access Database File
Microsoft SQL Server Database File.
The option they want me to choose does not appear in the list.
Microsoft SQL Server sqlclient
I tried following the instructions in this thread [http://forums.microsoft.com/msdn/showpost.aspx?postid=85686&siteid=1] where a user had a similar problem, but had no success.
I have reinstalled C#, reinstalled SQL Server Express 2005 with Advanced Tools, but neither helped.
Any help would be greatly appriciated.

Hi,
I'm trying to connect to a SQL Server 2005 express on my local Windows
XP Professional machine. I've searched the the MS fora and Google
but all the answers I find relate to trying to connect to a remote DB,
not local.
I run the aspnet_regsql.exe program in the interactive wizard mode, and
in the Select the Server and Database step when I click on the Database
drop-down list an error box pops up:
Connection failed
Failed to query a list of database names from the SQL server.
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)
Exactly the same error message appears when I:
* Change the 'Server' name from my computer's name to localhost, 127.0.0.1, or SQLEXPRESS. in the aspnet_regsql wizard.
* Stop my firewall (ZoneAlarm, native Windows firewall is disabled, and I switched off my cable modem at the time).
* Use the SQL Server surface area utility to enable remote connections
with both named pipes and TCP/IP), and also to enable CLR integration
in the Features section.
* Stop the SQL Server service. I did this to see if a different
error occurred, but it's as if aspnet_regsql.exe can't even see the SQL
Server.
* Have an additional instance of SQL Server running under my own username (see below).
I have an ASP.NET project (created by someone else on another computer) which attempts
to open a SQL Server database. It runs fine until the call to
System.Data.SqlClient.SqlConnection::Open() which raises an exception
with exactly the same error string as above (including what's in
parentheses). The connection string is "Data
Source=localhost;Initial Catalog=blah;Integrated Security=SSPI;" where
blah is specific to the company I'm doing this for.
I've created a test ASP.NET project to which I added a SQL
Database. My only option was to create a .mdf file in the
APP_DATA folder. The connection string is "Data
Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated
Security=True;User Instance=True" and it works fine and displays the
data I've put into the database, but in the Task Manager another
instance of sqlservr.exe appears (running under my username; the
existing sqlservr.exe runs under the NETWORK SERVICE username).
Should this happen??
If I stop the SQL Server service (or both of them), an error message in my web browser
appears (no exception is raised because there's no code in the project,
just a data-bound control). The error is the same as above,
except the parenthetical part is "(provider: SQL Network Interfaces,
error: 26 - Error Locating Server/Instance Specified)".
Edit: oh yeah, I've also tried to set up an ODBC data source connected
to SQL Server throught the Control Panel/Admin, but the ODBC applet
can't seem to see SQL Server either. I only get three options for
data sources: dBASE files (.dbf), Excel files (.xls), and MS Access
Database (.mdb). If I click on 'Add' and select "SQL Server" and
go on from there, it comes back and says the server doesn't exist or
refuses access. If I stop the service, the ODBC applet says the
sql server wasn't found.
Can anyone help please?
I'm stumped..

I have read all of the posts regarding this subject as well as 3"Dummies" guides and I keep having the same problems. I have a verysimple multi-user application that has to hit a database. Wecuerrently have this system deployed and it is working fine on adomain based network. We are scaling back and the network we will beusing is now a workgroup not a domain.It should be simple. I have XP boxes (clients) trying to hit the SQLServer Express database on a Windows Server 2003 machine. It is aclosed network so security is not an issue. I am trying to make thisthing wide open. All I want is for the user to be logged in on hisclient machine, run the application, and access/update the databasewithout having to re-authenticate to the SQL server. I want windowsto handle all of the authentication between the XP machines and theServer 2003 machine.Any suggestions would be greatly appreciated.

I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
These are my values in my Java app web.xml -
<init-param>
<param-name>DBDriver</param-name>
<param-value>com.microsoft.sqlserver.jdbc.SQLServerDriver</param-value>
</init-param>
<init-param>
<param-name>DBURL</param-name> <param-value>jdbc:sqlserver://localhostsqlexpress:1055;databaseName=CORNERS</param-value>
</init-param>
<init-param>
<param-name>DBUser</param-name>
<param-value>sa</param-value>
</init-param>
<init-param>
<param-name>DBPwd</param-name>
<param-value>myPasswd</param-value>
</init-param>.
And yes, the port is 1055 - I checked to find it.
I am using Microsoft SQL Server 2005 JDBC Driver 1.0 (sqljdbc_1.0.809.102).
Does anyone have any idea what is wrong so that the login fails in the Java application but works in the .Net application?

Everything was working fine. I have been able to connect using windows authentication. Then, I went into the ODBC manager to add a data source and it failed to connect so I went back into the Server management studio to modify users. After doing this I now get an error when I try to conenct the management studio to the SQL server.
I wasn't modifying the login for my windows account that I normally use, I was modifying a different one, however I now get the message "An error has occured while establishing a connection to the SQL server. This kind of problem can ocure because the default behavior of the server does not support all connection methods" blah blah.
Does anyone know how I can attach to the server? Or, do I need to somehow remove the server and create a new one? How would I do that?
Thanks in advance for any input.

I've seen the following error posted when people try to connect to their server via their applications but didn't see anyone having problems when trying to connect with SQL Server Management Studio Express. Am I missing something here? This is the 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)(Microsoft SQL Server, Error: 2)>>The server is not remote so I don't see why I need to enable remote connection. I am also using the default connection settings.

On my home machine without permanent network connections enabled, I cannot get the Management Studio connect to the database server. Always get this error:
Cannot connect ot MPLIAMSQLEXPRESS
Additional Information:

Hey all! I am new in this form and also new with the SQL serve. I have installed that free express edition of SQL server 2005 and when i am trying to connect to server from my C#.net application i am not able to do it and when i am trying to degug it gives me the error that is the user is not SQL thrusted user. I am able to connect directly thru SQL server using this userid and password but not thru VWD 2005 Express application.
I have read online that so many people are having that problem. so is it the problem of swl server Express edition or do i have to make some setting to connect to the application.
Please please please please someone guide me . I am stuck here in the beginning only. I would really appreciate it.
the code that i wrote is here:----
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
}
}
protected void Submit_Click(object sender, EventArgs e)
{
String querry;
SqlDataReader dbread;
try
{
SqlConnection conn = new SqlConnection(ConfigurationSettings.AppSettings["Conn1"]);
SqlCommand comm = new SqlCommand();
conn.Open();
querry = " Select password from login where userId='" + TxtUser.Text + "'";
comm.CommandText = querry;
comm.Connection = conn;
dbread = comm.ExecuteReader();
dbread = null;
if (dbread.HasRows)
{
while (dbread.Read())
{
if (dbread["password"].ToString() == Txtpwd.Text)
{
Response.Redirect("home.aspx");
}
}
Response.Write("Your Password Doesn't Match");
}
else
{
Response.Write("Your User Name Is Wrong");
}
conn.Close();
}
catch (Exception ex)
{
Response.Write(" This is an Error - " + ex.Message );
Response.End();
}

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've used Sql Server 2000 and Visual Studio 2003 for a few years. I've started a new position and they have access to Sql Server 2005 Standard and Visual Basic 2005 Express which I'd like to use for a new project. So I installed Sql Server 2005 and then VB 2005 Express on my workstation. I didn't choose the Sql Server option for VB Express because I already had Sql Server 2005 Standard installed with a simple database created. I created a simple vb project that justs connects to the database but I get the following error.
Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0000, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I looked at permissions in the database and it looks ok. I'm the db owner and I'm using Windows Auth. My connection string is
"Data Source=MySystem;initial catalog=AdventureWorks;integrated security=true;"
I thought I'd look at the starter kit to get some ideas about what the problem is, but when I started the movie starter kit project, it was upset that I didn't have Sql Server 2005 EXPRESS installed. Yea, but I do have Sql Server 2005 Standard installed.
Any help will be greatly appreciated. Thanks.

All,
I'm a newbie here so forgive me if I have missed something completely obvious.
I have bought a shopping cart script of a well known company (Evolve Merchant 5) and I wish to set it up locally on my development server, I created a virtual directory, set the web application up and get the asp pages to display perfectly. However, in the configuration file (global.asa & web.config) for the application it reguests information to be provided: <add key="DBName" value="Database name" />
<add key="DBServer" value="IP address of server" />
<add key="DBUserName" value="User name" />
<add key="DBPassword" value="password" />
<add key="AltPassword" value="password" />
What I can't determine is what the SQL Server 2005's IP address is? the pages of this application show when I type http://localhost/catalogue into IE, so I presumed the server address would be the IP of localhost, when typed ping localhost into command promt it gives me 127.0.0.1, but when I enter this into the config file and try to load the application it just hangs and then eventually says:
"Microsoft OLE DB Provider for ODBC Drivers (0x80004005)[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied./catalogue/global.asa, line 54"
I have created a new database in SQL Express called: merchant509 and restored the tables to it as the manufactures help files state, I created a new login called shop which uses SQl authentication, so as I can provide a password. So the settings should look like this:
<add key="DBName" value="Database name" />
<add key="DBServer" value="127.0.0.1" />
<add key="DBUserName" value="shop" />
<add key="DBPassword" value="1684" />
<add key="AltPassword" value="1684" />
But it doesn't work, does anyone know what i have done wrong?? the SQL server is runnign on the same computer as I am trying to access it from, it is set to accept all forms of comunication i.e. TCP/IP etc.. in the server configuration manager the IP address part of TCP/IP in protocols shows IP1 as 192.168.2.2 active yes enabled yes, and IP2 as 127.0.0.1 active yes and enables yes, I have tried the 192.168.2.2 and this gives the same errors, this is my registed IP on my home network.
I'm now stumped, I haven't a clue what else I can try, I would be very greatfull if anyone has any ideas.
Regards,
Daniel Coates

webacadie hit the nail on the head.Thanks a bunch.Finally I got coldfusion administrator to talk to Northwind database in sql server 2005 express.Basically all I did was look for TCP dynamic port under IPALL.Made a note of the number and enter it in the administrator.Also used 127.0.0.1 instead of localhost.Works like a charm.

I've installed SQL server 2005 Express and set up a database called StockData. I'm running the following code in a visual C# windows app to test the connection:
System.Data.Sql.SqlDataSourceEnumerator instance = System.Data.Sql.SqlDataSourceEnumerator.Instance;
DataTable tblSource = instance.GetDataSources();
string strSource = tblSource.Rows[0][0].ToString() + "/" + tblSource.Rows[0][1].ToString();
SqlConnection sqlConn = new SqlConnection();
sqlConn.ConnectionString = "Data Source=(local);Initial Catalog=StockData;Integrated Security=true";
sqlConn.Open();
I have verified that the SQLEXPRESS service is up and running. The strSource variable shows the machine and SQLEXPRESS instance name when I step through, so I know that the application is recognizing the service. But when I get to the "sqlConn.Open()" line, I get the following error message:
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)"
Source=".Net SqlClient Data Provider"
ErrorCode=-2146232060
Can anyone tell me what I'm doing wrong here? This is driving me nuts. Thanks.

I know there have been many posts made on this subject; however, despite the resources available, I have not been able to get this to work! I've spent time working on this here and there over the last couple of months only resulting in frustration. I am finally posting to solicit help for my situation to figure out what is wrong with my SQL Server or firewall configuration.
Two machines connected to a router, one wireless, one wired. Both have SQL Server Express and the Management Studio tools installed. From either machine I can connect to its local SQL Server Express instance.
I have enabled Shared Memory, Named Pipes, TCP/IP, and VIA in the SQL Server Configuration Manager. (BTW what is VIA?)
I have added sqlsrvr.exe and sqlbrowser.exe to my Windows Firewall exceptions. I have tried disabling Windows Firewall. One of the machines is configured as DMZ in the router configuration.
Please, someone offer up some brilliant diagnostic steps I am missing to expose what is wrong in my setup and make this work... Thank you!

Here is a strange one. Have a sql2k box that I upgraded from 6.5 back. Conversion went fine, everything was ok with the sql install. Created and scheduled maintenance jobs while logged on to the box. A few days after the conversion, Enterprise Manager cannot register the server(error message is 'Data source name not found and connection libraries do not exist'). This inablilty to register the server only occurs when working on the server itself. You can register the server while connecting from another box with EM.
So, do some checking and find that the box itself does not recognize SQLSRV32.dll (etc) as even existing on the box BUT IT DOES EXIST in the normal places, it was a working install just a few days prior. As far as the box is concerned, the network libraries do not exist. Therefore, cannot register the server locally, cannot create a Data Source using the SQLSRV32 driver, cannot start the Sql Server Agent(so no scheduled back ups, etc).
Went so far as to re install the connectivity and client tools, which did not fix the issue.
Does anyone have any ideas?

All --
Please help.
Is it possible to connect to MDF file without having SQL Server 2005 Express installed on the machine?
That is-- can one connect directly to an MDF in the same way and Access MDB file can be used?
If no, then is there any way around this?
If yes, then are there any limitations?
Please advise.
Thank you.

What could be the possible reason for this and how can i configure sql
server 2005 express edition to make connections without specifying any
portnumber in the connection string. Both the sqlserver database
service and browser services are running.
Regards
Salil

Hi am very new with VB.net (Visual Studio 2005) and the first time try to use the sql server 2005 express. I did create a trial.mdf (local server) and complete procedure to attach the trial1.mdf in Microsoft SQL Management Studio Express.
I try to use VB to connect /open/close it with the following codes: (but failed)
-----------------------------------------------
Imports System.Data.SqlClient
Public Class Form1
'Link database
Dim DB_Location = "c:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTrial1.mdf"
Dim MyConnection = "Server=localhost; DataBase= " & DB_Location & "Integrated Security=SSPI"
Dim sqlConnection As New SqlConnection(MyConnection)
'Use database
Dim strSQL As String = "SELECT FROM Trial1 WHERE col2 = 'trial' "
Dim cmd As New SqlCommand(strSQL, MyConnection)
sqlConnection.Open() ' ----> error
cmd.ExecuteNonQuery() ' ----> error
sqlConnection.Close() ' ----> error
End Class
-------------------------------------------
At the last 3 line of codes I got the errors ... can someone explain why & help me to correct it?
Thanks for any help

I am unable to connect to my database on a VPS server using server management studio express. I am able to ping the server. can connect to a local database but i have the same issue as others
Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
have set the server so that it will allow remote connections and reset the server just to make sure that it has been implemented.
when i use osql in command prompt to make a test connection it tells me this
[SQL Native Client]Named Pipes Provider: Could not open a connection to SQL Server
[SQL Native Client]Login timeout expired
[SQL Native Client]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.
on this forum it says to perform a ping and and an a ping a- to my server which does work.
Have been working on this for 3 days and can't figure it out.
Even had a guy in New Zealand who is usually my messiah of SQL and he can't figure it out so I'll be impressed if someone knows the answer.
I will buy a crate of beer for the person who solves this for me as this problem is costing me money! Maybe even 2 if done by end of tomorrow 6pm GMT!
If you don't want the beers, i will be more than happy to give a virtual pat on the back. :-)
If you need any more info, i will be watching this thread like a hawk so i'll happily answer any questions that you may have if i can.
Thanks in advance
