I'm having some issues getting started using C# and SQL Server Express.
I'm trying to create a C# project to just connect to a SQLSE DB just so I can start learning how to use it. I've used the SQLSE Surface Area Config Utility to enable remote and local connections, and it gives me error 26 about the default config not allowing remote connections.
I then altered the connection string from .SQLEXPRESS to .MSSQLEXPRESS which is the instance of the service running on my PC. When I do this, it throws error 25: invalid connection string. I also have ensured that the 'User Instance' field is set to True (but I have tried it set to true and false, with no change: error 25 is still thrown).
All -- Please help. I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005. Note that I do not want to use the "Attach a database file" type of connection string. Note that I am using the site http://www.ConnectionStrings.com as a reference. Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS... (A) What exactly does the error in Item 4 mean? (B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string? (C) Are there any alternatives? (D) What do you suggest?
I have SQL Server Express and VB 2005 Express installed in a Microsoft Windows XP Pro PC that is a terminal PC in our office Network. My Network Administrator has granted my terminal PC for Administrator Use. I tried to do the ADO.NET 2.0-VB 2005 programming in my terminal PC and I could not get a remote connection in the Window Form Application via Window Authorization. I do not know how to make this kind of remote connection in my Network. Please help and advise.
I have VC++ express and MSSQL SMS express and have an application working nicely locally. The Data explorer and data connections part works really easily.
Now, I want to make the application available to my home network.
I mapped the drive where the database is and called it Z: so I could put my "release" on my other network PC and assumed it would find Z: if I mapped the shared network drive on that machine and called it Z:
But: I can't even add the mapped connection on the local machine, I get:
The file "Z:databasescalorie.mdf" is on a network path not supported for database files. An attempt to attach.....etc"
It works fine on the original F drive.......
Am I approaching this the wrong way. How should I distribute to network PCs?

I am new to VB.Net coming from a VB6 background using the VB.Net Express and have even loaded the SQL Express. The learning curve is not to bad until you get to dealing with connecting to db's. However, in trying to fill a grid with data, manipulate it and then update it has not been any fun either. There does not seem to be enough information out there dealing with these two as of right now.
Anyway, trying to add a datasource connection for a grid has resulted in a real problem even using the connection wizard. I keep getting the same error that the default settings for SQL express does not allow remote connections. However, I thought that I have corrected that. Unfortunately, with VB express I cannot even seem to talk to my SQL 2000 server either because it gives me the same exact error. I am thoroughly frustrated with it and ready to just do it in VB6.
I am open to any thoughts on this. I do not like using bound controls, except in a few situations. I would like to create it unbound if at all possible. If someone could give me some ideas as to what to do and where to go with this I would appreciate the help. I have been doing a lot of reading and a descent understanding what is needed to talk to a SQL db.
i have downloaded and set up SQL Express on my desktop. When i click connection, it only shows server on the network (in the office). i want to connect to the sample database on my machine (don't want to connect to servers in the office), how can i do that?
When trying to connect to a db in VB.net express I get this warning

Hi, I am relatively new to this. I have installed VB 2005 and that has installed a version of SQL Server 2005 Express on my local development machine. I am using VB to develop some demo sites and i can create DB's in the App_Data file and they work when I test and run then by pressing Ctrl + F5. However i have some demo tutorials that require Northwind and Pubs to do them. So i have installed Northwind and Pubs using the cms prompt and the InstNwnd.sql install. They said everything has been installed fine. This is where the problem starts. I open new connection in VB, or asses for that matter and try to open my local server machine (just my desktop running WindowsXP pro), Which is called Optiplex. Sometimes i get the optiplex appear in the dropdown that asks for your to choose a server and other times it doesnt. Eevn if the machine appears it doesnt let me chose Pubs or northwind from the second drop down. I think i must have SQexpress running on the machined named Optiplex because i have the SQL server configuartion manger on it. That tells me i am running SQL Server(SQLEXPRESS) and SQL Server Browser both switched on and running. By the way i have set my SQL manager to run as Local service. One thing that i consider strange is that when i have had SQLServer Express running on other machines normally there was a little icon running in the right hand corner of the the task bar. Does anyone know what is going on with my mchine and have i got the SQL server setup correctly? Just one last piece of additionally information is that i have a folder called C:SQL Server 2000 Sample Databases which is where the MDF files are located. Thanks a million Sanson
Hello. I have created a website with a local database file. When I had it locally the connection worked just fined. When I put the files on the IIS the site can't find the database anymore. This is the connectionstring that i have locally: <connectionStrings> <add name="conn" connectionString="Data Source="GjoniSQLEXPRESS; AttachDBFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataACO.MDF; Integrated Security=True" providerName="System.Data.SqlClient" /> </connectionStrings>

Hello everybody Im writing an application in VB6 (with sp5) and using SQL Express 2005 for database. I need to run this application over the network with clients working on Winxp and Win98 also.
This works fine the the host system(where the SQL express is installed) but if i try to run the applicatoin from a network PC, running on Windows 98, Im getting an error "Login failed for user '' Factory/Guest"
When i Change the connection string to use User id and password of SQL Logins , (The user is set 'Public' as DB Role membership in SQL Express for the Production database)
I am having the worst time getting connect to my database.. I just get error. But I have read somewhere (microsoft) that SQL Express can't have over 1gb of ram. My pc has 2gb will this stop me for building the sites and connecting to it? Do I need to upgrade my PC and the webserver to sql workgroup for me to be able to work on this.
2 question. Can I just upgrade the server and connet to the server from my pc to build the basic pages in Dreamweaver in the web.config file as long as my PC is online? This way I don't have to buy it for my PC as well. If this is possible what would be a connection string i would use in the web.config file to make this work.
We created one application, with deployment. When we install the application on another machine, it will attach a database in sqlexpress instance. For eg. c:Programfilesoursoftwarenamekmsdb.mdf.
Now i am having one more webservice running on that machine as dll(not webservice source code). In this web service i am reading that database values. But the connection string is giving some error message.
I have recently installed SQL Server Express on a desktop machine for a program that we use. I am in need of adding additional machines to gain access to the server for the database. Right now, the program is working on the local machine fine. What do I need to do or enable for access on a local LAN? All machines are XP Pro on a workgroup. Also, the software we use has a remote connection manager that requires inputting the server address for the machine. Is it better to use the computer name or IP address, and then what is that format? SQL Instance name is 'uesafh' if that helps. Any other information that I can provide, please let me know.
What is the connection limit of SQL Server express. Currently I am using Access database and it allows < 300 concurrent connections. The database is supposed to be accessed through a web page. If there are hundreds of users hitting the page and updating the database, will there be any synchronization issue. How many concurrent connections can be opened?
If I create any other user (test, felix, fido, etc) in my database, that user can login successfully through Management Studio Express except not through an ODBC connection. Thus, this is a very bizarre issue. I have made sure this user has the same roles as SA. My instance is configured to handle SQL Server Authentication and Integrated. This works fine in Studio Express, but not in the ODBC connection.
When using "SA" login, I can connect to Management Studio Express and through an ODBC connection. Seems rudimentary enough, however, if I change the name in the ODBC connection i get
"Connection Failed,
SQLState '28000', SQL
Server Error 18456,
Microsoft SQL Native Client SQL Server Login failed for user 'xyz'"
Any ideas? Do I need a different ODBC Administrator?
I have a problem connecting with Sql Express. Here is the setup: 3 machines, all running SqlExpress on XP.Machine 1 is a notebook, and machines 2 and 3 are Tablet PC's. I seem to have all 3 set up identically, and can connect between 1 and 2. However, Machine 3 is the problem. From 1 and 2, I can "see" the instance on 3 but not connect, and from 3, I can "see" the instances on 1 and 2, but not connect.
I have read through the docs and have SqlBrowser on and configured, I turned off the firewall on 3, and have Sql SErver enabled for remote connections on all three machines. I have perused the security settings for Sql on 3 and it appears to be the same as the other two machines. I have matching administrator accounts on all 3 machines.
The connection error is the standard one about can't connect or don't have privileges.
I think this is a network problem and here is why: I used to use machine 3 at work. My employer's IT dept set it up to give me network and internet access. Although I can "see" the SqlExpress services in SSMS, I can't expand the network node using Windows Explorer on machine 3, and I can't access the shared folders on machine 3 from machines 1 and 2.
Is there a networking setting that may be preventing me from connecting to the other machines?
i am stuck in a strange situation. I have successfully built my application setup through InstallSheild 12. Which first installs SQL Express user define instance as a pre-requisite and then install my application files. First time when i run my application (without restarting the pc), it connects successfully with user define instance. But as i restart my PC and try to open my application, it is not connecting with database. i am using the following command line to install SQL Express 2005 user define instance:
if i change Remote connection to "using both TCP/IP and named pipes" through "SQL Server Surface Area Configuration" and then restart my pc again. My application connects successfully with Database.
Please guide me where i am getting wrong in building setup. do i have to add something in my command line to not get this error
The last connection string I used is: Server=192.168.0.3;Initial Catalog=dbase;User ID=guest;
In the connection string I added port 1433, servername instead IP, different users id...but can´t connect. I can ping visualstudio emulator from sql server, now are in the same lan but in future pda have to connect to
server using gprs.
Where is the error??
Thanks in advance.
PS. I´m reading some post that indicates SQL Server Express doesn´t allow any remote connection?
I've got a lovely issue that I would love to solve because it has brought down my server's ability to use an SQL server. So I was using Visual Web developer and liked it soo much, I decided hey, why not upgrade and go to Visual Studio 2005 professional. So I backed up my databases in .bak files and zipped up by websites (just in case) and uninstalled everything that had web developer or sql in its name from my computer (vista x64).
Then I installed Visual Studio 2005 professional and figured out it didnt come with a SQL manager so I then downloaded SQL Management studio express to handle that. I opened SQL management studio and connected perfectly fine using "DESKTOPSQLEXPRESS" where DESKTOP is my computer's name using Windows Authentication. I then set up a few databases how they were set up previously and that all worked out alright.
The issue came into when I tried to access the websites that used sql queries. whenever i tried to open a connection i got "An error has occurred while establishing a connection to the server" Error 40 to be exact. Now it says that my sql server may not accept remote connections so I went to SQL Server surface area configuration and made sure that it accepts pipes and tcp/ip, restarted the server and still get the error.
Info that may come in handy... The websites are connecting on localhost so firewall really isn't an issue. Continuing, they are using the SQL Server Authentication and the user names and passwords are right.
Sorry if that is long but I think all the needed information is there. If anyone has any ideas on how to help, please speak up. If no ideas come up, can someone please provide me with information on how to do a clean install of VS and SQL express?
Is there any article out there that explains why we nedd to put "SQLExpress" in the connection string for SQLExpress db. ( need to show by boss why ) ..
InnerException = {"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,...
I have changed the Sql Server settings to accept remote connections(use TCP/IP and named pipes) and I have also tried connecting using <machinenameSQLEXPRESS> and <.SQLEXPRESS> as the datasource. But I still keep getting the same error.(also i get an error saying it is an unrecognised escape sequence)
I'm not sure if I am doing something fundamentally wrong. Please advise.
I'm trying to set up a connection string to a simple SQL Express database file
but I keep getting an error.
I copied this string from the Database object in the Database explorer. I changed the slashes to forward slashes to get rid of the escape sequence issue & changed the timeout & Integrated seccurity but apart from that it's the same.
The file is in the same directort as the Solution so I guess you can say it's Local.
Any ideas on a correct conenction string would be most appreciated

I'm a newbie to asp.net, but I have been a programmer for years.I have a question that I'm hoping someone can give me a good answerfor, I have been trying to set up a site remotely and I've been usingthe login control that comes with Visual Web Developer 2005 Express,this comes with SQL 2005 Express. The remote site is not a companycomputer, but basically a host that I'm paying for. When I deploy onthis remote site and try to log in I get 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 thefact that under the default settings SQL Server does not allow remoteconnections. (provider: SQL Network Interfaces, error: 26 - ErrorLocating Server/Instance Specified)Using the Database Explorer I noticed that on my laptop the databasefile is sitting on my C: Drive. I also noticed that on the remoteserver I deploy to has all my files on their D: Drive. My question isdo I have to set my SQL 20005 Express file up locally exactly the waythe file will set remotely? In other words... If, on the remoteserver, my files will be on D:(url)asp_data... in order for my logincontrol to be able to use it, it has to be set the same way?Also, does that remote site need to be set up with SQL 2005 express aswell? or will the site be able to work off of that file?And Finally, I also have SQL Server 2000, if I wanted to use this login control (the one that comes with Visual Web Developer 2005), how can Ireference this server instead of SQL 2005 Express? It seems Visual WebDeveloper 2005 wants to use it automatically.Thanks in advance
I am having trouble connecting to SQL Server 2005 Express using ASP.NET written in VB.NET (1.1 Framework) in VS2003. I am trying to programmatically connect to the SQL Server. Since this is a redistributable web application and I don't want to rewrite the connection string every time I distribute a copy, is there any way to automatically get a connection string without prompting the end user for one? I can get the server name and the data base name, but I don't know how to get a username. It returns an error saying SERVERASPNET can't log on. Can anyone help?
I am using SQL server express 2005. I can drag and drop a grid control on to my web form and choose the data source to point to a SQL server database. Then datais nicely displayed on my web form. Now I need to manually create my connection to the database as I need to read from a text file and then populatea database table with those values I read from the text file. I have not had any success with this though and I am stuck and need some help. Below is my C# code and I list the web.config code where my connection string is stored. Note that I can trace into the C# line of code below. If I then do a "Quick Watch" on "myConnection" in the debugger, the followingerror message is displayed: ServerVersion 'myConnection.ServerVersion' threw an exception of type 'System.InvalidOperationException' string {System.InvalidOperationException} So I don't know what the problem is here. If someone can help me out I would be forever thankfull
C# code: SqlConnection myConnection = new SqlConnection(ConfigurationSettings.AppSettings["TheDividerConnectionString"]);
Here is the connection string as defined in the web.config file: <connectionStrings> <add name="TheDividerConnectionString" connectionString="Data Source=BVCOMPUTERSQLEXPRESS;Initial Catalog=TheDivider;Integrated Security=True" providerName="System.Data.SqlClient" /> </connectionStrings>
I have an XP Pro machine running a classic ASP site in IIS - the version that comes on the XP Pro CD. The site makes a connection to an MSDE database on the same machine named InControl. I have moved that database to SQL Express 2005 and want to test it with the ASP site. SQL Express 2005 is running on a separate Vista machine. I am currently using this connection string: objConn.ConnectionString = "Provider=SQLOLEDB;Data Source=400SC;Initial Catalog=InControl;User ID=" & uid & ";Password=" & upass & "" Where 400SC is the name of the XP Pro machine and InControl is the database. The variables uid and upass are pulled from Session when the connection string is created. I have tried different Provider names and various combinations of server name and ip address with and without port numbers for the Data Source. All of them yield some variation of this error: Microsoft OLE DB Provider for SQL Server (0x80004005)[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied. What should the connection string look like? Thanks for the help. PS - If the solution involves a port, do I need to make that port an exception in the Vista Firewall?
