Can't Connect To A SQL Server 2008 Database Using VB 2010 Code
Sep 24, 2011
First off, my apologies for being a complete Newb! I have a SQL Express database that I use quite successfully to track my investments in several accounts. I built it myself, it's quite functional, and Im happy with it. The problem is that there are multiple account tables and updating them can be tedious in SQL Server, if multiple purchases and sales in multiple accounts have occurred in a month. Tedium can lead to errors¦
I want to use a connetction string for connect a databse in sql server express by vb.net? My code is : Cn1.ConnectionString ="Data Source=.SQLEXPRESS;Integrated Security=True;Connect Timeout=30;User Instance=True" but i when open then connection i see this error Cannot open user default database. Login failed. Login failed for user 'Shahab-PCShahab'.
I'm supporting an old vb.net program whose database it connected to was moved from SQL Server 2005 to SQL Server 2008. Is there a setting on SQL Server 2008 which will allow ODBC connections to access the database but not allow VB.NET to connect to it programmatically?
I am using VB 2010 Utimate on a Win7 64bit machine. I have an accdb database created through MS Access 2010 (database has a password). How do I go about connecting to it using codes without having to drag a database control on the form, also is it possible to code my form so that it will automatically detect the path of the accdb database? Also I want to view the whole table using datagrid view as well as perform database actions such as add, edit, del, save, search and etc.
I'm trying to connect from VB 2008 Express Edition to a database in an instance of SQL Server 2008. Both, VB and SQL Server are running on the same machine. From a VB project, when I try to define a new Data Connection I find just three Data sources available: [Code] I selected the last one but when I browse for the mdf file I cannot select it because it tells me that the file is in USE. I have stopped all the services but still I'm not able to link the database file.
Two questions: 1. Is there a way to connect to the SQL Server Instance and from there to select the desired database? 2. How to connect using the Database file.

In the beta version of Beta2 of Visual Studio Professional, when I choose add new connections, I can select a I can select a " SQL Server (SQL Client)" datasource, which works great with my SQL Server Express DB running on the local machine.
In VB2008 Express, though, I can't select a "SQL Server" in the datasource dropdown. I can only try to connect to a Microsoft SQL Server Database File.
When I actually try to connect using the .mdf file that is being managed by my local SQL Server, I get an connection error -- can't make connection to the server (and the usual message about enabling remote connections".
Im a beginner at vb.net, and just wanna ask if it is possible to make a vb.net app/client app that can connect to a database on an online web server???The app is locally on the client computer and the database is uploaded on the web server/host together with its website.
I'm trying to connect to a sql server 2005 database. I'm using the following connection string.
Dim cnn As OleDbConnection = _ New OleDbConnection("Provider=sqloledb;Integrated Security=SSPI;Initial Catalog=Iconics") Using this connection gives me the following error :
Error : Microsoft OLE DB PROVIDER FOR SQL SERVER : [DBNETLIB][Connection open(connect()).]SQL Server does not exist or access denied.
Does anybody know what is wrong with this connection string.

Where servername is "localhost". I need to make a connection to an online database (same data structure). What should I put at the servername in that case? I do have all the info about the database in question (Domain, Ip, etc...). Which part should i use?
I can connect to both databases with SQL Server Enterprise Manager, so I know the servers are up and available. One of them is SQL1, the other is SQLTEST.In my program when I use the following connection string, it work connects just fine:
conn = New DBConnect("Data Source=SQL1;Initial Catalog=SignInspection;Integrated Security=SSPI")
However, if I change SQL1 to SQLTEST the connection times out I don't get any errors other than the timeout error.I can run the profiler on SQLTest and see that it is most definitely NOT even attempting to connect.
EDIT:Well, it's a moot point now because I got authentication working properly on our SQL1 server.
First off, the web server is running IIS and .NET. Users are logged in to the intranet using Active Directory, and the .NET page needs to retrieve their log-in credentials (username most notably). The database is SQL Server 2005, running on a different machine. But the .NET app needs to impersonate as another user to connect to the database.
To successfully do both of these things go to Windows > Run, enter inetmgr and hit run. Navigate to the site and right click > properties, then click on the tab titled Directory Security, click Edit.., make sure only Integrated Windows Authentication and Digest authentication are enabled. Enter your proper AD realm and click OK. Apply the settings/hit OK.In web.config you need the following lines
replacing, of course, myDomainMyUserName and 123mypasswordgoeshere with the username and password that has login rights on both your domain and your sql server. The connection string can probably be modified, but this is mine and it works:
Every time I try connecting to an access 2007 database on FTP server, I receive the following error "Your network access was interrupted. To continue, close the database, and then open it again". Actually, I try connecting to the database on the FTP server by setting the value of "Data Source=ftp://anonymouslogin" in the connection string.
