Dim LeafCommandBuilder As OleDbCommandBuilder
Private Sub Form1_Load(ByVal sender As System。
Object, ByVal e As System。EventArgs) Handles MyBase。Load
Button1。Text = "读取"
Button2。
Text = "保存"

Private Sub Button1_Click(ByVal sender As System。Object, ByVal e As System。
EventArgs) Handles Button1。Click
LeafOleDbConnection = New OleDbConnection("Provider=Microsoft。
Jet。OLEDB。4。0;Data Source=" & LeafFileName & ";" & "Jet OLEDB:Database Password='" & LeafPassWord & "';")
LeafOleDbDataAdapter = New OleDbDataAdapter("SELECT * FROM " & LeafFormName, LeafOleDbConnection)
LeafData = New DataTable
LeafOleDbDataAdapter。
Fill(LeafData)
LeafNewRow = LeafData。NewRow
DataGridView1。DataSource = LeafData
