My OLEdb Update isn't working

I am trying to work with an Access database file in a new VB.Net Windows application.  

I used Access to create a simple database with one table (TestTable).

I then created a test application (OLETest) and added a OLEdbDataAdapter(odaTestTable).  Using the datapter I created a typed dataset (dsTestTable) and displayed it on my form using a datagrid.  I then added a button to call the dataadapter update routine.

When I run the test application I enter a new data row in the datagrid and press the Update button.  By stepping through the code I am able to see that the update command returns a value of 1, indicating that the update was completed and no exceptions are generated.

However if I exit and restart my application, the new row is not in the datatable.

What am I missing?

Here is the code.....

Public Class frmOLETest

    Private Sub frmOLETest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        odaTestTable.Fill(dsTestTable)
    End Sub

    Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click
        Dim I As Integer
        Try
            I = odaTestTable.Update(dsTestTable)
        Catch ex As Exception
            Dim x As String = ex.Message
        End Try
    End Sub
End Class
