【译文】如何用ADO代码实现窗体记录集的绑定

      将Microsoft Access 窗体绑定到一个记录集,你必须设置窗体的记录集属性为ADO记录集对象。这个窗体绑定到一个ADO记录集，更新时必须满足两个基本要求。基本要求是:

. 必须通过ADO更新

. 记录集必须包含一个或多个字段的惟一索引,比如一个表的主键。

VBA代码 ：

Private Sub Form_Open(Cancel As Integer)
 Dim cn As ADODB.Connection
 Dim rs As ADODB.Recordset
 
 '使用ADO连接
 Set cn = CurrentProject.AccessConnection
 '为ADO创建一个类实例
 '设置它的属性
 Set rs = New ADODB.Recordset
 With rs
 Set .ActiveConnection = cn
 .Source = "Select * FROM Customers"
 .LockType = adLockOptimistic
 .CursorType = adOpenKeyset
 .Open
 End With
 '用ADO给窗体的属性赋值
 Set Me.Recordset = rs
 Set rs = Nothing
 Set cn = Nothing
 End Sub

【原文】How to: Bind a Form to an ADO Recordset

      To bind a Microsoft Access form to a recordset, you must set the form's Recordset property to an open ADO Recordset object. A form must meet two general requirements for the form to be updatable when it is bound to an ADO recordset. The general requirements are:

•The underlying ADO recordset must be updatable via ADO.
•The recordset must contain one or more fields that are uniquely indexed, such as a table's primary key.

VBA：
Private Sub Form_Open(Cancel As Integer)
 Dim cn As ADODB.Connection
 Dim rs As ADODB.Recordset
 
 'Use the ADO connection that Access uses
 Set cn = CurrentProject.AccessConnection
 'Create an instance of the ADO Recordset class,
 'and set its properties
 Set rs = New ADODB.Recordset
 With rs
 Set .ActiveConnection = cn
 .Source = "Select * FROM Customers"
 .LockType = adLockOptimistic
 .CursorType = adOpenKeyset
 .Open
 End With
 'Set the form's Recordset property to the ADO recordset
 Set Me.Recordset = rs
 Set rs = Nothing
 Set cn = Nothing
 End Sub
