Attachment.OldValue Property (Access)

You can use the OldValue property to determine the unedited value of a bound control. Read-only Variant.

Version Added: Access 2007

expression .OldValue

expression A variable that represents an Attachment object.

The OldValue property contains the unedited data from a bound control and is read-only in all views.

Microsoft Access uses the OldValue property to store the original value of a bound control. When you edit a bound control on a form, your changes aren't saved until you move to another record. The OldValue property contains the unedited version of the underlying data.

You can provide your own undo capability by assigning the OldValue property setting to a control.

If the control hasn't been edited, this code has no effect. When you move to another record, the record source is updated, so the current value and the OldValue property will be the same.

The OldValue property setting has the same data type as the field to which the control is bound.
