VWD - Cannot Connect To Database.
Nov 17, 2006
Hi,
I'm on lesson 7 of the Bob Tabor video tutorial called 'Data binding to user interface controls'. Whenever I try to add an SQL database (add new item/sql database) I get the following error message:
TITLE: Connect to Server
------------------------------
Cannot connect to ALFIESQLEXPRESS.
------------------------------
ADDITIONAL INFORMATION:
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I have VWD installed, sqlexpress installed, everything really.
Any help would be appreciated.

I have an application that creates a new database during installation,and I've noticed some strange behavior. Once I've created thedatabase, I am able to immediately create tables and populate lookupdata, provided I remain connected to the server. If, however, Idisconnect and attempt to reconnect immediately, I'll get an errorsaying that my login is invalid for the new database.I can get around this by having my code simply wait 5 seconds beforeattempting to reconnect, but I'm curious to see if anybody here cangive an explaination for why this is happening. Here is a bit ofpseudo code to explain what I'm seeing:open new connectioncreate databasecreate tablespopulate tablesclose connection// open new connection /* can't do this yet, as it would break */for (int a=0; a<5; a++){Thread.Sleep(2000)try{open new connectionbreak;}catch{Debug("still waiting...");}}Running my version of this code, I'll see that "still waiting..."message go past 2-3 times before SQL Server wakes up and realizes thatI'm allowed to connect to it. Anybody know why?Thanks,Jason KesterExpat Software Consulting Serviceshttp://www.expatsoftware.com/---Get your own Travel Blog, with itinerary maps and photos!http://www.blogabond.com/

I am new to windows apps in .net 2.0. I am trying to create a windows service that will connect to a database and email info out to people that have had status changes.
Right now, I can not connect to the database. Here is the connection string:
Private cnn As New SqlClient.SqlConnection("Data Source=IPAddress;Initial Catalog=TheServer;Persist Security Info=True;User ID=userid;Password=password provider=SQLOLEDB.1;connect timeout=3600")
This is how I am trying to connect:
cnn.Open()
myCMD.CommandTimeout = 0
dr = myCMD.ExecuteReader
I keep getting an error message that I can not be logged on. I know that the credentials are correct because I use them for the web app. Something has to be wrong with my connection string, but what?
Thanks,
enak

I am attempting to connect to a database that has been uploaded to my server from my webpages on the server. This is the connection string that is currently used:
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Restaurants.mdf;Integrated Security=True;User Instance=True"
When attempting to connect to the database I receive this error 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I realize that I cannot make a remote connection using SQL Server 2005 Express Edition, but cannot find the proper connection string for it to connect to the uploaded database.
Accessing the database doesn't require a log on by the user as all the information is public.
The authentication mode in the web.config file is set to "Forms".
If there is any other information required so that this problem can be solved, please ask for it.
Thank you in advance,
Me

Ok I have several sites on a server that have connected to databases on a different server for a long. Out of the blue today none of the sites on the server can connect to any databases on the other server. However, sites on other servers can connect to databases on the same db server.This is the message I get: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)The database server runs SQL Server 2000 not 2005 I can connect to the database from desktop (with an asp.net application or sql server management studio), I can ping the database server fine from the production web server, but my applications can't connect for some reason. There is nothing in the event log to suggest a problem, any ideas what could be causing this?

Hello,
I have posted awhile ago about this issue, but after taking the advice and trying to get help from GoDaddy, nothing has worked yet. I am using the user login control, and then I changed the connection string in the web config file according to what Go Daddy's help file said, making sure to make proper server, id, and password names. It still won't go through, can anyone help?
Thanks

I recently uninstalled SQL Server due to connection issues I started having. I could start the DB and connect/edit tables in Ent Mgr etc, but all the sudden, none of my code could make DB connections.
So, after reinstalling now nothing works. I cannot even connect in Ent. Manager. I went to Administrative Tools->Services to make sure it was running, and SQLSERVER isn't even listed under services. What happened? Is there another step after installing SQL Server I missed to get the service up and going. Do I need to do something in ODBC connections?
I am on Windows XP with SP2.

Greetings,
A newbie needing some guidance. We have SQL running on our Windows 2003 server. When I connect via the Enterprise manager I have two instances of SQL running.
SRV01ACT7 (Windows NT)
SRV01WEBAPP (Windows NT)
When I click on the ACT instance I get the following error:
A connection could not be established to SRV01/ACT7
Reason: Login Failed for user xxxxadministrator.
Please verify SQL Server is running and check your SQL Server registration properties.
I only get the message when I try to connect to the SRV01ACT. The connection to SRV01WEBAPP works fine.
I checked with SQL server manager and both instances are running and no one has reported any problems connecting to either one of them.
The way it acts, its as if SQL server has lost the ability to authorize a connection via the windows account. As if it has lost its associatoin to the administrator account. So while the instance still runs and is functional, I just can't connect to it and manage it.
I have connected via remote desktop from a WinXP machine and the server console. Both end up with the same error.
Can Someone give me step by step instructions on how to correct this?
Any help please!!!

Update: I got it working. I had to create an odbc connection on my machine (guess I forgot to do that this time).
I copied a SQL 2005 database from another machine (detached it first. I can connect directly in SFT SQL Server Mgmt Studio, but I cannot connect from VFP using SQLCONNECT(). I've overlooked something. My login is the db_owner and everything else. Any ideas? SQL Server is running on the same machine that I have VFP9 on. It is setup for both SQL Server and Windows Authentication and I can connect to every other database I have attached.
TIA,

I can't connect to a SQL Server 2000 database.
I opened SQL Server 2005 Management Studio and tried to connect. In the Connect to Server dialog box, when I go to the Server Name dropdown and browse for my database server on the network, the server is not in the list. (A different SQL Server 2000 database server does show up there.) I tried manually entering the server name (and password, etc) but it doesn't connect.
When I go to the server, the db is running and apps that use it work fine. I can ping the server, and I can map a drive to it.
I can't connect using Visual Studio 2008 either. When I try to create a SqlDataSource in Visual Studio the db server isn't in the dropdown list. Also, when I manually create a connection string it doesn't connect.

Hi I recently installed SQL server but I can't connect to the database. The error message is "under the configuration SQL server does not allow remote connections". What does this mean? I have already followed Step 1, 2 and 3 in the FAQ but I got the same error message. I had enabled TCP/IP. I have changed the values in IPALL and I have added SQL to the firewall exceptions list, but I still can't connect. And I don't understand, isn't the server on the local computer, so what does it means by "remote connections"?

Hi,
with the Visual Studio(Add New Data Source) i was able to add a SQL Compact 3.5 database to my desktop-project. Everything seems to be ok: dll assemblies, location of the database in my application folder...
But when trying to connect to the database like this:
SqlCeConnection _conn = new SqlCeConnection();_conn.ConnectionString = Properties.Settings.Default.MyDatabaseConnectionString;_conn.Open();the debugger comes up with this message:
'The file name is not valid. Check the file name for the database. File name = |DataDirectory|MyDatabase.sdf ]
i also tried to add the database path manualy. SqlCeConnection _conn = new SqlCeConnection(@"Data Source = C:MySQLCompactMyDatabase.sdf");_conn.Open();Then i get:Invalid provider type. [ Db version = 3004180,Requested version = 3004180,File name = C:MySQLCompactMyDatabase.sdf ]What's wrong? I'm using VS2005 and Vista 64. Thanks for your help, i'm new to SQL...'

Can anyone please direct me to an easy to understand Description, Article or Video tutorial that shows an example on how to programatically connect to an SQL database and retrieve data from a collumn using C# and VISUAL WEB DEVELOPER 2005 EXPRESS EDITION. Also, what namespace should be imported to do this? (From what I have gathered out of the help, it seem that System.Web.UI.WebControls is the one)
I am trying to create a "news letter" web page. I have a basic form and when I hit "send" then the code in the background should access the database with all the recipient info, and retrieve all the E-mail addresses, Names, etc. and include it in each e-mail.
( I don't know if it is just me, but the help included with VISUAL WEB DEVELOPER 2005 EXPRESS EDITION is extremely difficult to understand - from a beginner point of view).
Thanks!

Right now I'm just looking at websites how to create a database and putting it in the App_Data folder which is no problem. What I want to do is Programmatically do it. in the example code that I see it says:
Dim ConnString as string = ConfigurationManager.ConnectionStrings(connStringName).ConnectionString
or
Dim MyConnString as new sqlconnection = New SqlConnection(ConfigurationManager.ConnectionStrings(connStringName).ConnectionString)
now every time I put the connStringName in the parenthasis it tells me that its an error: Name connstringName is not declared.
I figure the connstringName is the name in the connectionStrings in the web.config.
So I am doing something wrong here, I would appreciate any help.

Hello,Is it better to use a DSN connection or using a connection string Set Connection = Server.CreateObject("ADODB.Connection") Which is easier to use and more reliable? Also could I have all the connection info on one page and then just include it with a include statment everytime I need to query the database?? Thank you, Rich

I am developing a web site with asp.net 2.0 and c#, using Visual Studio 2005 and Microsoft SQL Server 2005 ( I am still learning about these technologies and languages ).
I transferred my web site files to a new computer.
I created a empty SQL database called "SiteData.mdf", I stopped the SQL server and then I replaced this database with a previous one with the same name and already populated with data.
I used this maneuver in order to avoid having to insert all data again.
The web site works fine when running inside Visual Studio, however when I try to run it in its published format it gives this error message:
Server Error in '/MA' Application.
Cannot open database "SiteData" requested by the login. The login failed.Login failed for user 'CENTAURUSASPNET'.
I also observed that inside the SQL Server Management Studio, in the database properties, it shows "ETHERASPNET" as User or Roles ( however "ETHERASPNET" was created using the old computer's name [ or should I say domain ? ]) but the permissions list correctly displays the new name "CENTAURUSASPNET".
I think that I, probably, should create a new user using the name "CENTAURUSASPNET" because it would use the name of the new computer ( or domain ) and then I should delete the old user name. Actually I tried to do that but I get the message "An object named ‘CENTAURUSASPNET' cannot be found".
So,
1) What should I do to get the database being connected with the published web site ( note: I am publishing it in my own computer for awhile ) ?
2) How do I create the new user name "CENTAURUSASPNET" ?
3) I also would like to know why the name of the database in the Server Explorer panel of VS appears as "centaurus.SiteData.dbo" -while- inside the Object Explorer panel of the SQL Server Management Studio it appears simply as "SiteData" ?
