Answer 1

これは、入力DataGridViewとDataTable

    Private bindingSource1 As New BindingSource()    
    Private dataAdapter As New OleDbDataAdapter()

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load    
        Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<FilePath>;User Id=username;Password=password;"    
        Dim selectCommand As String    
        Dim connection As New OleDbConnection(connectionString)

        selectCommand = "SELECT * FROM...<YOUR SELECT Query>"    
        Me.dataAdapter = New OleDbDataAdapter(selectCommand, connection)

        Dim commandBuilder As New OleDbCommandBuilder(Me.dataAdapter)    
        Dim table As New DataTable()

        Me.dataAdapter.Fill(table)    
        Me.bindingSource1.DataSource = table

        Dim data As New DataSet()

        DataGridView1.DataSource = Me.bindingSource1    
    End Sub

これはあなたが望むものです（を使用してDatagridデータをデータベースに保存するDataAdapter）

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim table As New DataTable()

        Me.bindingSource1 = Me.DataGridView1.DataSource    
        table = Me.bindingSource1.DataSource

        Me.dataAdapter.Update(table)    
    End Sub

End Class
