This example demonstrates the DateCreated and LastUpdated properties by adding a new Field to an existing TableDef and by creating a new TableDef. The DateOutput function is required for this procedure to run.

Sub DateCreatedX()

Dim dbsNorthwind As Database
Dim tdfEmployees As TableDef
Dim tdfNewTable As TableDef

Set dbsNorthwind = OpenDatabase("Northwind.mdb")

With dbsNorthwind
Set tdfEmployees = .TableDefs!Employees

With tdfEmployees
Print current information about the Employees
table.
DateOutput "Current properties", tdfEmployees

Create and append a field to the Employees table.
.Fields.Append .CreateField("NewField", dbDate)

Print new information about the Employees
table.
DateOutput "After creating a new field", _
tdfEmployees

Delete new Field because this is a demonstration.
.Fields.Delete "NewField"
End With

Create and append a new TableDef object to the
Northwind database.
Set tdfNewTable = .CreateTableDef("NewTableDef")
With tdfNewTable
.Fields.Append .CreateField("NewField", dbDate)
End With

.TableDefs.Append tdfNewTable

Print information about the new TableDef object.
DateOutput "After creating a new table", tdfNewTable

Delete new TableDef object because this is a
demonstration.
.TableDefs.Delete tdfNewTable.Name
.Close
End With

End Sub

Function DateOutput(strTemp As String, _
tdfTemp As TableDef)

Print DateCreated and LastUpdated information about
specified TableDef object.
Debug.Print strTemp

Debug.Print " TableDef: " & tdfTemp.Name
Debug.Print " DateCreated = " & _
tdfTemp.DateCreated
Debug.Print " LastUpdated = " & _
tdfTemp.LastUpdated
Debug.Print

End Function

сори, это для формы. Вот как надо ? currentdb.TableDefs("Таблица").DateCreated
? currentdb.TableDefs("Таблица")..LastUpdated

что не складывается? кстати у меня тут ошибка. надо currentdb.TableDefs("Таблица").LastUpdated

И не должно, LastUpdated показывает измения объекта (TableDef) а не данных в нем 1. Все изменения в дынные вносить только через формы.
2. На события формы регистрировать изменения данных записывая действия в отдельную таблицу.
