connection string

hi to everyone its me again..
[php]
questioning the endlesses questions...
i have a connection string in vb.net application and it works fine..
[/php]
but when i use this connection to asp.net it throws an error: System.Data.SqlClient.SqlException: Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

VB Code:

Dim cn As New SqlConnection("integrated security=true;initial catalog=northwind;data source=local host")

what im i missing in asp.net???
im very new in this thing since this is my first approach on asp.net..

pls. help...:cry:

Extra! Extra! Get your connection strings here:

Get your other connection strings here:

Connection string aside, am I the only one who finds it odd that it said failed login (null) - which tells me there's no user context, and since he's using trusted security.... that's why it failed. There's no user context from which to connec to the database with.

Is the SQL Servers security setup to use Windows Authentication of SQL Server Authentication?
If SQL Server Authentication, then it would expect a username and password in the connectionstring.

That's true. The connection string does say "integrated security=true;" which tells me WinNTAuth is to be used, - but that doesn't mean the server is set up that way. I don't know under what context the page is running. Obviously, what ever user context (if any) the code is running under, that user doesn't have permissions. Since it reported the login as (null) I have to assume that it isn't running under any user context. In which case it needs to be converted over to use SQL authentication, in which case the connection string would need to be changed, or the code needs to be forced to run under a specific user context that has the appropriate security to access the database.

thanks guys for the reply..i tried what you have suggested if it works..

If you want to use windows authentication, you need to turn off anonymous access in IIS. If that is checked, windows credentials won't be passed on to ASP.NET.

thanks hellswraith for the reply..
actually i already solve this scenario..
i just add new login (computername\Aspnet) and it do the trick..

hey sorry for my stupidity im very new in this thing and i just want to know if asp.net allow global declarations..ie. i want ot declare my connection in global so that i can access it everywhere..



thanks in advance mate..

Store your connection string in the web.config file. Add a section that looks like this (search on the web for more info):

<appSettings>
<add key="ConnectionString" value="your long connectionstring here" />
</appSettings>

Then, anywhere in your app, you can do a
MyString = System.Configuration.ConfigurationSettings.AppSettings("ConnectionString")
