Sets or returns a bookmark that uniquely identifies the current record in a
Recordset object.
Syntax
expression .Bookmark
expression A variable that represents a Recordset object.
Remarks
For a Recordset object based entirely on Microsoft Access database engine tables, the value of the Bookmarkable property is True, and you can use the Bookmark property with that Recordset. Other database products may not support bookmarks, however. For example, you can't use bookmarks in any Recordset object based on a linked Paradox table that has no primary key.
When you create or open a Recordset object, each of its records already has a unique bookmark. You can save the bookmark for the current record by assigning the value of the Bookmark property to a variable. To quickly return to that record at any time after moving to a different record, set the Recordset object's Bookmark property to the value of that variable.
There is no limit to the number of bookmarks you can establish. To create a bookmark for a record other than the current record, move to the desired record and assign the value of the Bookmark property to a String variable that identifies the record.
To make sure the
Recordset object supports bookmarks, check the value of its
Bookmarkable property before you use the
Bookmark property. If the
Bookmarkable property is False, the
Recordset object doesn't support bookmarks, and using the
Bookmark property results in a trappable error.
If you use the
Clone method to create a copy of a
Recordset object, the
Bookmark property settings for the original and the duplicate
Recordset objects are identical and can be used interchangeably. However, you can't use bookmarks from different
Recordset objects interchangeably, even if they were created by using the same object or the same SQL statement.
If you set the Bookmark property to a value that represents a deleted record, a trappable error occurs.
The value of the Bookmark property isn't the same as a record number.
Example
This example uses the Bookmark and Bookmarkable properties to let the user flag a record in a Recordset and return to it later.
Sub BookmarkX()
Dim dbsNorthwind As Database
Dim rstCategories As Recordset
Dim strMessage As String
Dim intCommand As Integer
Dim varBookmark As Variant
Set dbsNorthwind = OpenDatabase("Northwind.mdb")
Set rstCategories = _
dbsNorthwind.OpenRecordset("Categories", _
dbOpenSnapshot)
With rstCategories
If .Bookmarkable = False Then
Debug.Print "Recordset is not Bookmarkable!"
Else
' Populate Recordset.
.MoveLast
.MoveFirst
Do While True
' Show information about current record and get
' user input.
strMessage = "Category: " & !CategoryName & _
" (record " & (.AbsolutePosition + 1) & _
" of " & .RecordCount & ")" & vbCr & _
"Enter command:" & vbCr & _
"[1 - next / 2 - previous /" & vbCr & _
"3 - set bookmark / 4 - go to bookmark]"
intCommand = Val(InputBox(strMessage))
Select Case intCommand
' Move forward or backward, trapping for BOF
' or EOF.
Case 1
.MoveNext
If .EOF Then .MoveLast
Case 2
.MovePrevious
If .BOF Then .MoveFirst
' Store the bookmark of the current record.
Case 3
varBookmark = .Bookmark
' Go to the record indicated by the stored
' bookmark.
Case 4
If IsEmpty(varBookmark) Then
MsgBox "No Bookmark set!"
Else
.Bookmark = varBookmark
End If
Case Else
Exit Do
End Select
Loop
End If
.Close
End With
dbsNorthwind.Close
End Sub
This example uses the LastModified property to move the current record pointer to both a record that has been modified and a newly created record.
Sub LastModifiedX()
Dim dbsNorthwind As Database
Dim rstEmployees As Recordset
Dim strFirst As String
Dim strLast As String
Set dbsNorthwind = OpenDatabase("Northwind.mdb")
Set rstEmployees = _
dbsNorthwind.OpenRecordset("Employees", _
dbOpenDynaset)
With rstEmployees
' Store current data.
strFirst = !FirstName
strLast = !LastName
' Change data in current record.
.Edit
!FirstName = "Julie"
!LastName = "Warren"
.Update
' Move current record pointer to the most recently
' changed or added record.
.Bookmark = .LastModified
Debug.Print _
"Data in LastModified record after Edit: " & _
!FirstName & " " & !LastName
' Restore original data because this is a demonstration.
.Edit
!FirstName = strFirst
!LastName = strLast
.Update
' Add new record.
.AddNew
!FirstName = "Roger"
!LastName = "Harui"
.Update
' Move current record pointer to the most recently
' changed or added record.
.Bookmark = .LastModified
Debug.Print _
"Data in LastModified record after AddNew: " & _
!FirstName & " " & !LastName
' Delete new record because this is a demonstration.
.Delete
.Close
End With
dbsNorthwind.Close
End Sub
