Newbie Connection Problem

I'm having a problem writing aconnection string in .NET. I'm trying to use:

SqlConnection myConnection = new SqlConnection("Provider=SQLOLEDB;Data Source=mssql;Initial Catalog= cat;UserId=ddd;Password=ddd;");

which unfortunately is giving me:

SQL Server does not exist or access denied.
Description: An unhandled exception occurred during the execution ofthe current web request. Please review the stack trace for moreinformation about the error and where it originated in the code.

Can someone tell me what I'm doing wrong? Thanks in advance!

do you only have Windows Authentication setup for your SQL server?

or - if not -does the user you put in the connection string actually have an account in SQL Server?

|||We're not using Windows Authentication and there is a valid account being referenced in the SQL Server (I just put letters in my post to show what I was using)|||

mtarby:

SqlConnection myConnection = new SqlConnection("Provider=SQLOLEDB;Data Source=mssql;Initial Catalog= cat;UserId=ddd;Password=ddd;");

May be a silly question: can Provider key word be used in SqlConnection object? How about remove the Provider attribute from the connection string?

|||Without wanting to come across as too condescending, i'm taking it that your server is called mssql (and it's the only instance on your machine) and that the username and password are correct...?|||Yes, those are just placeholders I put in my post. The server, user name and password are all correct in my actual code|||

have you tried:

SqlConnection myConnection = new SqlConnection("Server= YourSrvr; Database=YourDB;UserId=ddd;Password=ddd;");|||I ended up adding an entry to my web.config file and its working fine now. Thanks for the help!

Newbie - SqlConnection statement

I'm trying to get a combobox to fill with values from a table. I've
set up an example using the Northwind database with the Categories
table. Dragging in the CategoryID field onto my form as a combobox,
I've set the following properties for the CategoryID combobox:
Value member = "CategoriesBindingSource - CategoryID"
Display Member = "CategoriesBindingSource - CategoryID"
This seems to bring in the correct values in the two non-index fields
(CategoryName and Description). I've then added the following code to
the combobox:
Dim Conn As SqlConnection
Conn = New SqlConnection("Database=Northwnd.mdf")
'Conn.Open()
Dim da As SqlDataAdapter = New SqlDataAdapter("SELECT
CategoryID FROM Categories", Conn)
Dim ds As New DataSet
da.Fill(ds, "Categories")
CategoryIDComboBox.DataSource = ds
'CategoryIDComboBox.ValueMember = "CategoryID"
'CategoryIDComboBox.DisplayMember = "CategoryID"
End Sub
The lines that are commented out are other ideas that I've tried to no
avail. I left them here in case they are relevant.
I suspect that at least part of my problem is in the SqlDataAdapter
statement where I am pointing to the database. I am working on a
standalone pc.
Can anybody see where I am going wrong?
Thanks,
