Updating Access Database

[DJYUNGSTYLEZ]

I'm having problems updating my existing access database in vb. Whenever I exit my program, the changes made won't save. How can I correct this? This is the code I have so far...

    Private Sub Customer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'AutioEssentialsDataSet3.Customer' table. You can move, or remove it, as needed.
        Me.CustomerTableAdapter2.Fill(Me.AutioEssentialsDataSet3.Customer)


    End Sub

    Private Sub SaveToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveToolStripButton.Click
        Me.Validate()
        Me.CustomerBindingSource2.EndEdit()
        Me.CustomerTableAdapter2.Update(Me.AutioEssentialsDataSet3.Customer)

    End Sub
