I'm having problem finding a good Vb.net example that shows how to dispose a sql connection via the idisposable interface. Also with the 'using' statement. Does anyone have a good small example using both of these keywords?

Dim conn As SqlConnection = New SqlConnection(dsn)
Try
Dim cmd As SqlCommand = New SqlCommand("SELECT * FROM Employees", conn)
Try
conn.Open()
rdr = cmd.ExecuteReader()
While rdr.Read()
Console.WriteLine(rdr(0))
End While
Finally
If Not cmd is Nothing Then
cmd.Dispose()
End If
End Try

conn.Dispose()
End If
End Try


Hope this Helps
