Hi, I had an old web application created during asp.net 1.1 and it have a connection problem with the sql server 2005 when it is mirgrated to a new webserver with dotnet framework 2.0 platform. I have enabled the remote access(TCP/IP and named pipes) in sql server 2005, did all the neccessary things, check whether the TCP/IP is enabled, named pipe is enabled... I created another web application using VS 2005. The database connection works perfectly well.This are the connectionString from the old web application.<appSettings> <add key="ConnectionString" value="Server=127.0.0.1;Database=somedb;User id=user; Password=somepassword; Trusted_Connection=False; POOLING=FALSE"/></appSettings> Thankyou in advance!
I got an approach like that: 1) Read something from DB - check the value, if true stop if false go on2) Read the second Value (another SQL Statement) - check the value etc. Now I could open the connection at 1) and if I have to go to 2) I leave the connection open and use the same connection at 2). Is it ok to do that? The other scenario would be opening a connection at 1), immediately close it after I read the value and open a new connection at 2). Thanks for the input!
Hi, Has somebody had a problem like this before? Exception Details: System.Data.SqlClient.SqlException: 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) That's part of the code: SqlConnection con; string sql; SqlCommand cmd; con=new SqlConnection("Data Source=elf/SQLEXPRESS;Initial Catalog=logos;Integrated Security=SSPI;"); sql="SELECT max(id_kandydat) from Kandydat"; con.Open(); cmd=new SqlCommand(sql,con); int id = Convert.ToInt32(cmd.ExecuteScalar()); con.Close(); SqlDataSource7.InsertCommand="INSERT INTO Kandydat_na_Kierunek(id_kandydat, id_kierunku, id_stan) VALUES ("+"'"+id+"'"+","+"'"+DropDownList1.SelectedValue+"'"+","+'1'+");"; I don't really get it. I'm nearly 100% sure that before some changes in my project this had worked perfectly. Does anybody have any idea how to make it work again? I would be very grateful for any help. And, yesy, I know it is quite common error, but proposed solution found didn't help.Regards,N.

One issue has got me stuck while getting to build an application(ASP.NET/SQLSERVER). Whenever I try to connect to SQL Server 2005 (installed on local host) using Visual Web Developer 2005 Databse Explorer, I get the following error message:
"An error has occured while establishing a connection to the server. when connection 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)"
NB: - on SQL Servers' Surface Area Configuration, Remote connections are set to "Local and Remote connnections" and "Using both TCP/IP and named pipes".
Hi, I've created an "ASP.NET Web Application" project in Visual Studio and I want to simply open a connection to a database in SQL Server. All I have done is adding these 3 lines below without modifying any other generated codes by Visual Studio.(I've done this within code behind in Page_Load() not by <script> tag within HTML code) public class WebForm1 : System.Web.UI.Page { private void Page_Load(object sender, System.EventArgs e) { // Put user code to initialize the page here SqlConnection c = new SqlConnection(); c.ConnectionString = "workstation id=BABAK;integrated security=SSPI;initial catalog=db1;persist security info=False"; c.Open(); } ... } But I get this error : Server Error in '/projects/fortest/tDB2' Application.-------------------------------------------------------------------------------- Login failed for user 'BABAKASPNET'.

I posted this on the Dotnetnuke forums but no answer for it, so since it is a SQL error I guess maybe someone here might know. I installed the core forum that comes with the installation, the page runs great until I add the forum module. I get this error:

HiI am connecting to an external web server running sql 2005 absolutly fine when testing a site using my localhost on my laptop. How ever, when i deploy the site to my server i get the error 40 code - the external database its trying to connect to is on a different server to both my own localhost and my own server.here is my connection string from my web.config: <add name="plightConnectionString" connectionString="Data Source=111.222.333.444;Initial Catalog=plight;Persist Security Info=True;User ID=xxxxxxx;Password=xxxxxxxx;" providerName="System.Data.SqlClient" /> I've googled the error but all answers require alterations to the server where the sql database is installed, and it works from my localhost anyway - is there anything i need to do to my own server which is running the website? Regards
I'm using VS2005 and SQL2000. I created a database name "myDatabase" in SQL Server 2000 and built a website that connet to this database. When I'm running this website in VS2005 IDE (press F5 or Ctrl-F5), everything is OK. I publiced this site. When I connect to database on my computer, everything is OK also, but when I connect to database on another computer, an error occurred like this :

Now, I don't know how to fix it. Pls help me as soon as possible. Regards.
I have created a new aspx site on ‘server 1’ which connects to an sql server 200 on ‘server 2’ ‘Server 1’ is a test server and all works fine. I then move the site onto ‘server 3’ and receive the error below.
This must be a problem with ‘server 3’. I have installed .net version 2 on this server and there are currently no aspx sites running of this server. There must be smothering not configured right. There are other sites on the server that are talking to the SQL server.
Any help would be great. Thanks

In my code, I need to update the table on the linked server according to the XML input. A table variable is used to store the value from XML.
But the collation of the linked database doesn't match with the default collation used by the table variable, so the table join fails.
I am thinking about to open the connection to the linked server directly, and use the target database. So the table variable collation should be as same as the target database collation.
Is it possible to open the connection to the linked server in c# ?

No issues if we install Visual Studio 2005 on WinXP or W2k3.
Is there any configuration we need to set on vista to allow sql connection?

I have see this link (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=192622&SiteID=1) and other links and done the changes they recommend, but it does not give any positive results. I have also in the firewall added named pipes internal and external port 445. I have also in RUN executed "cliconfg.exe" and enable the tcp ip port number 1433 and named pipes "sqlquery". In the sql server configuration manager, have I enabled both tcp/ip and named pipes. The same in the server surface area configuration. I have also enabled remote access.
Still having the same problem??!!?? Iam out of ideas ...
Please need help, thanks in forehand! Nikita

This was originally posted in the SSIS Forum, but a member of the IS team suggested it be moved here. "Most recently I got this error (Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) so does this mean that SQL Server is still trying to use named pipes even if I only have TCP/IP enabled in SQL Server Configuration Manager?"
I'm having the same issue, and here's our scenario:

I had SQl Express version installed previously and everything worked. I could connect to one server running SQL Express and a different server running full up SQL 2005 enterprise version.
I uninstalled All SQL express programs and installed tools from SQL 2005 developer.
I have rebooted, started the program directly (not using a link of any kind) and all attempts fail. After dismissing the error msg the tool opens and I can run queries agains the DB but the database engines and related tables do not show.
My work station is Windows XP with SP2 installed.
I have googled the problem extensively and tried solutions found but none have solved the problem.
My configuration is: Vista Home Premium, SQL Server Express and I'm trying to access a database on an instance named AxisSQLServer in a C# application.
As a result of a previous post (SQL Network Interface, error 28), I have selected "Local and Remote, using TCP/IP only" in the Surface Area Configuration for Services and Connections.
SQL Server is started. SQL Server Browser is started.
Both programs have been added as exceptions to the firewall (don't understand why I would need to do this since everything is on the same box).
Have turned off McAfee AV.
My connection string reads: string connectionString = "Data Source=localhost;" + "Initial Catalog=AxisSQL;Integrated Security=SSPI"; where AxisSQL is the database I'm trying to read.
I have looked at and followed numerous forums and blogs and always get the same error.
My connection string (to a remote instance of SQL Server Exress 2005) is exactly the same when the web files are located on my local machine or my remote machine, and while it works fine when I use the local web files, I get the following error when I use the remote files:
"Named Pipes Provider: Could not open a connection to SQL Server [53]"
As you can see, since it works from the local version, I've setup SQL to accept remote connections via TCP/IP and Named Pipes. I'm using IIS7 on the local, and IIS6 on the remote, in case that makes a difference. I have other sites setup the same way, which work fine.
I am writing an application using VB.Net 2005 for the Windows CE 5.0 device and it is connecting to a SQL Server 2005 Mobile Edition Database. The trouble I'm having is establishing a connection to a SQL Server Mobile database on the device.
Here is the code I am using:
Code Snippet Public gConnectionString As String = "Data Source=Program FilesMobAppMobDB.sdf;Persist Security Info=False;"
Code Snippet
Imports System.Data.SqlServerCe
Public Class DBManager
Public Shared gSQLCEConnection As SqlCeConnection

If gSQLCEConnection IsNot Nothing Then
Throw New InvalidOperationException("Connection already open.") End If gSQLCEConnection = New SqlCeConnection(gConnectionString) Try
gSQLCEConnection.Open() 'Error occurs here Return True Catch ex As SqlCeException

A first chance exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll
I believe that the first few lines are caused by the icons/pictures that I have included with my app, but the SqlCeException line occurs when the connection to the .SDF file is trying to be established.
Here is the exception output:
Message: "" (Blank) HResult: -2147024882 NativeError: 0 Source: SQL Server 2005 Mobile Edition ADO.NET Data Provider
Programs under Remove Programs on the PDA are: Microsoft .NET CF 2.0 ENU-String R... Microsoft .NET Compact Framework... Microsoft SQL Client Microsoft SQL Mobile 2005 Microsoft SQL Mobile 2005 [EN] Microsoft SQL Server 2005 Compact... Microsoft SQL Server 2005 Compact... Microsoft SQL Server 2005 Compact... Microsoft SQLCE 2.0 Microsoft SQLCE 2.0 Dev
Any ideas on what could be stopping this connection from being established? It was working before but all of a sudden just stopped. I have warm booted, cold booted, and rebuilt with no luck and also checked that SQL Query Analyzer is not running on the PDA and that the connection string is valid. The call to OpenDB occurs in the form_load of the startup object.
I am accessing SQL2005 with C# code using OleDbConnection.
A try and catch block catches the following error once a while between the Open() and Close() of the connection:
ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.
I do not even have any idea where to start to debug this. The ExecuteNonQuery() runs a delete SQL query. It works 99.9% of the time. I do not see anything wrong when this error happens.
