ASP TableAdapters. Getting row data from a SQL parameter query - sql

Question

Trying to get my head round ASP.NET DALs and TableAdapters and I'm hoping somebody can help me with getting the column data when using SQL query parameters.
If I have a TableAdapter with a query that returns one or more rows, I can get row and column data from the datatable no problem. For a simple query which returns one row I can use:
SQL: SELECT firstName, lastName from Names WHERE ID=1
Dim MyAdapter1 As New ProjectTableAdapters.NamesTableAdapter1
Dim f As String = MyAdapter1.GetNames.Rows(0)("firstName")
Dim l As String = MyAdapter1.GetNames.Rows(0)("lastName")
However if use a TableAdapter which has a query with a parameter I keep getting exceptions thrown. I'm sure this is simple, if someone can point me in right direction (vb if possible). Thanks a lot.
SQL: SELECT firstName, lastName from Names WHERE ID=#ID
Dim ID As Integer = 1
Dim MyAdapter2 As New ProjectTableAdapters.NamesTableAdapter2
Dim f As String = MyAdapter2.GetNames(Rows(0)("firstName"),ID) [throws exection]
Edit:
I think I have it working now - my bad syntax...
Dim f As String = MyAdapter2.GetNames(ID).Rows(0)("firstName")

Public Function MyFunction() As DataSet
Dim conString As String = "Connection String"
Dim conn As New SqlConnection(conString)
Dim da As New SqlDataAdapter()
Dim cmd As New SqlCommand With {
.Connection = conn,
.CommandText = "SELECT firstName, lastName from Names WHERE ID=#ID",
.CommandType = CommandType.Text}
cmd.Parameters.Add("#ID", SqlDbType.Int).Value = 1
da.SelectCommand = cmd
Dim ds As DataSet = New DataSet()
conn.Open()
da.Fill(ds)
conn.Close()
Return ds
End Function
