SQL Server Express And Vista Connecting Issues...

Alright I glanced over the forums to see if there was an answer for this and I didn't see one. I saw a few similar issues however nothing that fixes my issue. Here is my problem.



I installed SQL Server 2005 Express on my Vista partition along with Visual C# Express. For some reason I cannot get the SQL Server 2005 Express to function correctly. Back when installed this on XP it worked flawlessly, and I don't even recall doing anything special...I installed it and it worked. I do know that you have to manually add the user account to the admin list for the SQL server on Vista, and I did that. I chose the option to have it do it during installation as well as through the SQL Server Surface Area Configuration just to be sure.

I am just trying to get the basics of it working right, and that is connecting to the server using C# and filling a dataset...it shouldn't be this hard. This morning when I started with this I could connect and fill my DataSet programmatically however it wouldn't pass the test through the Data Source Configuration Wizard. When I did it manually, as I said it worked and filled the DataSet with the info I asked for below in the code sample. After getting annoyed by it not working through the wizard I decided that maybe I had my permissions wrong and I may have messed up when installing it. So I uninstalled everything to do with SQL Server 2005 and reinstalled it fresh.

This time when I installed it I made sure to set it up to use Windows Authentication. Now it will pass the Test in the Data Source Configuration Wizard and everything is working by doing it that way. However now it doesn't work when I do it manually with the code below(same code as before when it worked...lol). When I use the code below it crashes with the error: "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)". When I go through it with the debugger it throws that error at the call dataAdapter.Fill(...). The code is the following:




Code Snippet

string connStr = "server=localhost;Trusted_Connection=yes;database=northwind";

string commandStr = "Select CompanyName, ContactName from Customers";



SqlDataAdapter dataAdapter = new SqlDataAdapter(commandStr, connStr);

DataSet dataSet = new DataSet();

dataAdapter.Fill(dataSet, "Customers");

DataTable dataTable = dataSet.Tables[0];



foreach(DataRow dataRow in dataTable.Rows)

lbCustomers.Items.Add(dataRow["CompanyName"]+

" ("+dataRow["ContactName"]+")");

Why doesn't that work yet I can basically ask for the same information and it will work if I do it through the wizard? If it works 1 way I wouldn't think there could be any issues with the server being accessed remotely, right?
