can't get my example to work either :/ Looks really simple, doesn't error, but records never get written to the file.

Code:
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim objRow As DataRow = DataSet11.Table1.NewRow()
        objRow("Text") = TextBox1.Text
        DataSet11.AcceptChanges()

        OleDbConnection1.Open()

        Try
            OleDbDataAdapter1.Update(DataSet11.Table1)
        Catch ex As Exception
            MsgBox(ex.Message)
        Finally
            OleDbConnection1.Close()
        End Try

    End Sub
Maybe some brighter soul will enlighten us both.
