View 2 RepliesVisual Studio :: Create Connection String To Perform Test With Text Book?
Sep 14, 2010I have installed VS 2010 Ultimate and it came with SQL 2008. what version it is and also how to create a connection in place to keep using the Oreilly examples to hopefully learn how to develop in C#. I have been learning but it is getting more difficult. I try to follow the steps but it just does not make sense. provide some easy steps to check version and connection method to sql using 2010,
I did see a post for sql management(http://www.microsoft.com/downloads/details.aspx FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b&displaylang=en). I am going to download to hopefully be able to view the database. We have sql server 2008 at work and I have used the studio management for sql to run queries and would like to do the same with the version that was installed with the installation of 2010 ultimate. I can get the connection to the database so I can start learning how to build a dictionary and list for some queries. My goal is to create a aspx file that will show entries in a database we have at work.
Visual Studio :: Error Unable To Add Data Connection. ExecuteScalar Requires An Open And Available Connection. The Connection's Current State Is Closed?
Sep 13, 2010I'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.
Visual Studio :: Add Connection / Use SQL Server Authentication - Fails On Windows 7 Pro
May 5, 2010I'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.
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 :: Can't Create Database - VWD2008 SP1 Asking For Sql Server Express 2005
Mar 24, 2010I've used the WebPI to install SQL Server Express 2008 and VWD2008 SP1. I made sure to install SQL Server first then install VWD. Whenever i use VWD now though and try to add a new SQL Server Database to my website i get the error message "Connections to SQL Server Files (*.mdf) require SQL Server Express 2005 to function properly."
I'm a little stuck as to where to proceed with this error. I've un-installed everything web development related and re-installed and still get the same error. I was under the impression that VWD2008 SP1 required SQL Server Express 2008 and wouldn't work with SQL Server Express 2005 so can't understand why it now wants it to be installed.

View 3 RepliesVisual Studio :: Can't Add An Connection To Database
Mar 31, 2011I 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.
Visual Studio :: DataContext And Connection String Changes
Jan 8, 2010I am using LINQ to SQL in a project. I create a new DataContext class (a "DBML").
This is a DotNetNuke portal, module project. DNN has a standard connection string named "SiteSQLServer." Of course, I want my DataContext class to use this same connection string.
In Server Explorer in Visual Studio, I have a connection to the development database. Of course, that connection knows nothing of the "SiteSQLServer" connection string in web.config.
When I drag a table into the DBML design screen, I get a popup message that the table I'm dragging in is from a different connection, and is it OK if it changes the connection string? If I say "No," then the table never comes in to the designer. If I say "OK," then Visual Studio adds a new connection string to my web.config file. Then I must click in the open area of the designer, then go to the Properties window and reset the connection string. If I miss this, then in testing everything works. But when I deploy to a production server, the connection fails. But even if I do not miss this, that extra connection string remains in my web.config file.
Is there a way to get Visual Studio to drop the table into the designer, and leave web.config alone?
Visual Studio :: Northwind Database Not Showing Up In VWDE2008 Add Connection Box
Mar 5, 2010I am a complete newbie when it comes to ASP.NET and SQL database access. I'm trying to learn so that I might become gainfully employed one day soon and better my life. I'm running through the Visual Web Developer Express 2008 beginning walkthroughs right now and I'm already stuck on the third one -- Walkthrough: Basic Data Access in Web Pages. I've installed MS SQL Server 2008 and downloaded the sample Northwind and pubs databases, and even (I think) attached the pre-built files using the DOS command: sqlcmd -S .SQLEXPRESS -i instnwd.sql. (Output was: Changed database context to 'master'. Changed database context to 'Northwind'.)
But, now, when I try to Add Connection through the Database Explorer in VWDE2008, nothing comes up in the Connect to a Database field. Shouldn't it auto-populate? If I'm supposed to manually type a name in there, what should it be? I've tried "Northwind" and "SQLEXPRESS" with no luck (getting a generic Unable to Connect message). I've verified the database is running with SQL Server Configuration Manager and that all Client Protocols are enabled.

How To Use Client Side Code In Visual Studio
May 28, 2010I am a quite new to web development and I am trying to do some small form updates without causing a postback. For example making a control visible when a drop down list is changed.
I have so far come across some features that achieve this like the RequiredFieldValidator inside an update panels. However, these are specific to a single task.
What are my options to achieve these client side updates in Visual Studio? At the moment I don't know any JavaScript, so I would prefer another solution if it exists.

View 1 RepliesSQL Server Connection Client Tried To Connect To An Unsupported Version?
Jul 21, 2010We recently launched a new web site.there are roughly ~150 users active during peak hours.During peak hours,we are experiencing an issue every few minutes,the exception text is listed below.
System.Web.HttpUnhandledException:
Exception of type 'System.Web.HttpUnhandledException' was thrown.
---> System.Data.SqlClient.SqlException: The client was unable to establish a connection because of an error during connection initialization process before login.
Possible causes include the following:
the client tried to connect to an unsupported version of SQL Server;
the server was too busy to accept new connections;
or there was a resource limitation (insufficient memory or maximum allowed connections) on the server.(provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)
Our data access layer calls various DataTableAdapters using the following syntax.
EDIT
Yes, da is the name assigned to the DataTableAdapter. There is no connection.Open() because the DataTableAdapter takes care of all that, right?
using(TheDataLayer.some.strongly.typedNameTableAdapters.suchAndSuchTableAdapter da
[code]...
The connection string looks something like:
<add name="MyConnectionString"
connectionString="Data Source=myDBServerName;Initial Catalog=MyDB;User ID=MyUserName;Password=MyPassword"
providerName="System.Data.SqlClient" />
I'm trying to rule the problem being in Code.Is there anything "simple" that can be done to minimize this issue?
