How do I write the code to connect an .aspx webform to a MS SQL server and database

VS 2008
This was done in VS 2008 the web forms are registration and log in forms with aspx controls. I created the database and the tables ( but am having issues with the constraints for 3 columns). I am trying to find out how to connect the 2 and where would I put the code. I am not a programmer and I am trying to do this the company cannot afford a programmer. I know based on what I already have, the pages are not connecting to the database.

I am pretty sure that my registration information is not stored in the table but I did not get an arror on that one. In particular, on my log in page I received the following: : System.Data.SqlClient.SqlException: 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Source Error: 
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Thanks. We'll let you know when a new response is added.

It seams to me that your connection string isn’t setup correctly. What’s the name of the server and instance that has your database information in it?
