There is no row at position 0. VB 2008

Having a problem with program saying there is nothing at row 0. I know there is but it says there is not. I am using SQL Server compact 3.5 sp1. I am following the HomeAndLearn Tutorial for access, so maybe the problem is that it is using access and I am using SQL Server CE?

Public Class Form1

    Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click
        Dim con As New OleDb.OleDbConnection
        Dim ds As New DataSet
        Dim da As OleDb.OleDbDataAdapter
        Dim sql As String
        con.ConnectionString = "Provider=Microsoft.SQLSERVER.CE.OLEDB.3.5;Data Source=|DataDirectory|\addressdb.sdf;"

        con.Open()
        MsgBox("A Connection to the Database is now open")

        sql = "SELECT * FROM AddressBookT"
        da = New OleDb.OleDbDataAdapter(sql, con)
        da.Fill(ds, "AddressBook")

        con.Close()
        MsgBox("The Connection to the Database is now Closed")

        txtFirstName.Text = ds.Tables("AddressBook").Rows(0).Item(1)

    End Sub

Are you sure that line isn't supposed to be before the con.Close()?

Ok I found problem, I did not have any data entered so naturally it would not display nothing because nothing was there to display.

OK, so this will not solve the problem, I am receiving this error on some of the buttons but not all. The code below represents a working and non working button

Working Button

Code:

---

Private Sub KryptonButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNextContact.Click
        If inc <> maxrows - 1 Then
            inc = inc + 1
            NavigateRecords()
        ElseIf inc = -1 Then
            MsgBox("No Contacts In The Database Yet")
        ElseIf inc = 0 Then
            MsgBox("You Are At The First Contact")
        End If

    End Sub

---

Non Working Button

Code:

---

    Private Sub btnFirstContact_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFirstContact.Click
        If inc <> 0 Then
            inc = 0
            NavigateRecords()
        ElseIf inc = 0 Then
            MsgBox("No Contacts In The Database Yet")
        End If
    End Sub
