Public Sub Snippet5()
    ' Create DataAdapter
    '
    Dim adp As New SqlCeDataAdapter("SELECT * FROM products", "Data Source = MyDatabase.sdf")

    Dim cb As New SqlCeCommandBuilder(adp)

    ' Create and fill the dataset (select only first 5 rows)
    '
    Dim ds As New DataSet()
    adp.Fill(ds, 0, 5, "Table")

    ' Modify dataSet
    '
    Dim table As DataTable = ds.Tables("Table")
    table.Rows(1)("Product Name") = "Asian Chai"

    ' Add handlers
    '
    AddHandler adp.RowUpdating, AddressOf OnRowUpdating
    AddHandler adp.RowUpdated, AddressOf OnRowUpdated

    ' Update, this operation fires two events (RowUpdating/RowUpdated)  
    '
    adp.Update(ds, "Table")

    ' Remove handlers
    '
    RemoveHandler adp.RowUpdating, AddressOf OnRowUpdating
    RemoveHandler adp.RowUpdated, AddressOf OnRowUpdated
