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.

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
<authentication mode="Windows" />
<identity impersonate="true" username="myDomainMyUserName" password="123mypasswordgoeshere">
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:
Server=SQL1;Database=SignInspection;Trusted_connection=True;

One of my testers is testing my program that imports an XML file and puts all the data into correct fields in an Access database. He said on his Vista laptop he got an error saying: "Microsoft.jet.OLEDB.4.0 provider is not registered on local machine"
I know you don't have to have Access installed to run my program and I'm pretty sure all the OLEDB objects are in the .NET framework so why is it saying that?

Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed...
someone gave me a link to changing the database connection using an instance. When I tried to type what the instance of my SQL server 2008 I must have put the wrong information into the database connection instance.
What is the database connection instance called for SQL server 2008?

I have been learning about working with databases and VB. I have coded the connection string for a MS Access database to my VB project but i cannot establish a connection with my sql mdf database.
The code i used to connect to MS Access is:
<Dim dt As New DataTable()/>
<Dim match As String = ""/>
< Dim connStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
[Code]....
What is the connection code in order to manipulate data from the mdf file. Is it similar to the above code.

Well for some reason when i try to add a reference so that the oracle database can connect to the VB.NET 2010 program.In other words it shouldn't highlight certain code as if the database is not connected.Here is a clear summery as best as i can say what the problem is.
1. Connection from Visual Studio 2010 to Oracle plus server
2. Adding References will not be allowed for some reason.
3. The code (See example below on what it might be) is still highlighted even when i added the references several times.
I'll show just a small snip of the code coz it's more or less the same on most of the forms if i want to either update, delete, add or amend to the database. I'll show a few screenshots so to be clearer.I've tried by even looking over the notes and followed step by step and nothing works.Since i am not registered in this module this time i can't seek help of the lecturer so don't bother telling me to go and ask my teacher I've pestered the supervisor that i'd have to present this project to and she hasn't replied to my email at all so i have no clue what else to do in the matter.

I'm working on a program tthat will connect to a database and display some data. But everytime i press a button to connect my program to the database i keep getting this error message Cannot open database "Northwind" requested by the login. The login failed. Login failed for user 'Aron-PCAron'. Now the reason why i'm so stumped about this is because when i connect to SQL Server 2005 manually, the login works just fine! This is the connect string i've got running in my prgoram

before re-inventing the wheel, i want to ask you how i can do this best: I have a VB.Net application that uses a database connection to MS SQL Server 2005 (express version). There are users that input data with the application into the database lets say once to 2x an hour to once a minute. I want to do backups like this: Once a day or once a week (in the evening) a full backup, and whenever the program/user is idle for lets say 10 Minutes, i want to do an incremental backup (so that it does not take so long until he can work on after the backup).
There are no big security issues, just copying the backup data files to a network share / a different computer or server would be fine. i guess the average db size may be 300MB, but the daily increments about 1MB.
