It throws following error

Visual Studio :: Error Unable To Add Data Connection. ExecuteScalar Requires An Open And Available Connection. The Connection's Current State Is Closed?

Sep 13, 2010

I'm using Visual Studio 2008, and my database is SQL Server 2000.

I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.

But when I click OK, I get the error:

Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.

SQL Server :: Unable To Add A Connection To Database (SQL Server 2008) Using The Server Explorer

Aug 13, 2010

This issues has been driving me nuts. I am trying to follow the tutorial on [URL] I am trying to connect to a database in Microsoft SQL Server 2008. The way I do this is by right clicking on the "Data Connections" > Add Connection. Afterwards the Add Connection window comes up, I make sure my data source is "Microsoft SQL Server (SqlClient). And, I choose a server name; the only server I can choose is DomainSQLEXPRESS. The issue is when I go down to the "Select or enter a database name" drop down box, I do not see my database listed. I have also made sure in the SQL Server Management Studio that I have given my user all the privileges for the database. I know my explanation is kind of vague, but would anyone know the reason why I would not see my database?

DataSource Controls :: Connecting To SQL Server In Visual Studio 2008 Using Code - Error: 25 - Connection String Is Not Valid

Feb 2, 2010

Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.

Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting 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: 25 - Connection string is not valid)

However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.

Visual Studio :: Add Connection / Use SQL Server Authentication - Fails On Windows 7 Pro

May 5, 2010

I'm using VS 2010 RTM and SQL Server 2008 on my clean development laptop, running Windows 7 Pro.

Using Visual Studio's Server Explorer, I can easily do an Add Connection by simply right-clicking, and then completing the dialog, and choosing "Use Windows Authentication". I can then click the button "Test Connection".

However, if I wish to do an Add Connection, and then choose "Use SQL Server Authentication", I get a message "Login failed for user 'appSlir'", as shown here:

When I try the same thing on my other development machine, which is VS 2008, SQL Server 2008, and Windows XP Pro, it works fine.

There seems to be a problem/bug that prevents Add Connection with "Use SQL Server Authentication" to SQL Server 2008, when running on Windows 7 Pro.

Active Directory/LDAP :: .Net MVC 2 'Unable To Establish Secure Connection With The Server' Error?

Jul 23, 2010

We're having an error similar to the one detailed here. We get the error noted above when trying to do AD authentication from our .net (3.5) mvc 2 app. This is our first .net mvc app ...

- We are re-using a forms auth library written for a .Net 2 app

- that library/app/config used a service account with min. privileges for binding to AD

- This error occurs in VS 2008, have not tried deploying the app to a server yet (a little early for that)

- like the other user at the previously referenced thread, I can get the 'unable to establish ...' error to go away and display the log on page by putting *MY* credentials in instead of the service account (but not successfully authenticate)

- moving the service account into the same AD OU as my account does not seem to change it ... only using my account credentials does.

- trust level is set to full

Is this some odd permissions trick that is new with .Net 3.5 (even though the ADmembershipProvider is still a 2.0 libary)? This should have nothing to do with MVC itself.

Config looks like this (very standard, like every one else's)


The line/portion highlighted in the debug/stacktrace is:

type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

Visual Studio :: Unable To Connect To Database From Solution Explorer

Jan 16, 2011

I used the Web Site Administration tool to create a database with two users and two roles. The database created successfully and is showing up in Solution Explorer in the App_Data folder of my project, as expected. The problem is, that when I click on the database I get an error message saying that "SQL Server database files (.mdf) require SQL Server 2005 Express or SQL Server 2008 Express to be installed and running on the local computer." I, in fact, have 3 versions of SQL Server running on my computer. SQL Server Express (default instance), SQL Server Express (named instance for Outlook 2010 Business Contact Manager), and SQL Server 2008 R2 (Developer Edition). If I create a new connection in Server Explorer and then attach the database file, it attaches fine. It's only in Solution Explorer that it somehow is not connecting.

Visual Studio :: Can't Add An Connection To Database

Mar 31, 2011

I used Data Connections to connect a database but couldn't make it.

1. I used Windows Authentication to log on to database, my database's name wasn't displayed in Select or enter a database name dropdown menu, so I enter my database's name then I pressed Test Connection button, it said "This connection can't be tested because the specified database doesn't exist or isn't visible to the specified user."

2. So I used SQL Server Authentication to log on to the server,then I put my database's name in Select or enter a database name dropdown menu box, then press OK it's said that "Login failed for user 'xxx' or Try to press Test Connection button it said that "Login failed for user 'xxx'.

I'm sure that I use a correct username and password and I think it's a problem about VS can't see my database in SQLExpress2008.
