NET is both powerful and simple to use. Notice how each column in the selected tables has a check box to the left of its name. To add the column to the view, just select the check box. As you do so, you'll see the columns added to the column grid and the stored procedure that will be used to build up your view being built for you automatically. At any point you can click and drag the columns in the column grid to change their order, or you can even just click in the SQL Editor and write some SQL code by hand.
NET Framework (something that may still be a little unfamiliar to you if you come from a Visual Basic background) means that it's trivial to create your own Connection object that subclasses the SqlConnection object. In that object you could override the class destruction event handlers and explicitly close the connection when the object goes out of scope. There's no such thing as a free lunch, though, and while that approach is perfectly legal in a true 00 application, the other programmers on your team may not be so happy.
In my writing cave (really, it has no windows and only a single lightbulb), the machine is called Saratoga and since I'm using MSDE as the database server, I need to suffIx the machine name with "\ VSTE". If your machine name is MyServer and you're also using the MSDE server, then you would change the dataSource to "MyServer\ VSTE". You can pick up the correct name to use from a quick glance over at the name of the database server in Visual Studio's Server Explorer. With that out of the way, you can actually create a Connection object: dbConnection = New SqlConnection("Data Source=" &dataSource ";Integrated Security=sspi;" + _ "Initial Catalog=" + database) + _ Be careful not to get confused here-creating a Connection object is not the same as connecting to a database.
