该范例说明 AbsolutePosition 属性如何对枚举所有 Recordset 记录的循环进程进行跟踪。它通过将游标设置为客户端游标,使用 CursorLocation 属性激活 AbsolutePosition 属性。
Public Sub AbsolutePositionX() Dim rstEmployees As ADODB.Recordset Dim strCnn As String Dim strMessage As String ' 使用客户端游标为雇员表打开一个记录集。 strCnn = "Provider=sqloledb;" & _ "Data Source=srv;Initial Catalog=pubs;User Id=sa;Password=; " Set rstEmployees = New ADODB.Recordset ' 使用客户端游标激活 AbsolutePosition 属性。 rstEmployees.CursorLocation = adUseClient rstEmployees.Open "employee", strCnn, , , adCmdTable ' 枚举记录集。 Do While Not rstEmployees.EOF ' 显示当前记录信息。 strMessage = "Employee: " & rstEmployees!lName & vbCr & _ "(record " & rstEmployees.AbsolutePosition & _ " of " & rstEmployees.RecordCount & ")" If MsgBox(strMessage, vbOKCancel) = vbCancel _ Then Exit Do rstEmployees.MoveNext Loop rstEmployees.CloseEnd Sub
