How To Cancel DAO AddNew Edit Without Leaving Current Record
  资料类型: Database 上传时间: 2001-02-21 阅读次数: 1377



VB's documentation on the AddNew and Edit methods states:

"In the Professional Edition, if you are not using a data control and use one of the Find or Move methods or close the recordset while an Edit or AddNew operation is pending, any existing changes will be lost and no error will occur."

Thus, a simple way to cancel an edit is to move off of the current record.But it's actually possible to cancel an edit without leaving the currentrecord (eliminating the need to move back to it):

' In VB4...

Dim rs As Recordset



' Begin an edit

rs.Edit

...

' Cancel it

rs.Move 0



' In VB3...

Dim ds As Dynaset

Dim sBkMk As String



' Save bookmark of current record

sBkMk = ds.Bookmark

' Begin an edit

ds.Edit

...

' Cancel it

ds.Bookmark = sBkMk
