SUMMARY
This article demonstrates how to use the Restrict method. The Restrict method applies a filter to the Items collection, returning a new collection containing all items from the original that match the filter. This method is an alternative to using the Find method or FindNext method to iterate through specific items within a collection. Find or FindNext is faster than filtering if there is a small number of items. Restrict is useful when performance is not a concern.

In the Visual Basic for Applications Automation example that follows, the Restrict method applies a filter to the Contact items based on the item's LastModificationTime property.
Public Sub ContactDateCheck()
Set ol = CreateObject("outlook.application")
Set olNameSpace = ol.GetNamespace("MAPI")
Set MyContacts = olNameSpace.GetDefaultFolder(olFolderContacts).Items
Set MyItems = MyContacts.Restrict("[LastModificationTime] > _
'05/15/97'")
For Each MyItem In MyItems
MsgBox MyItem.FullName & ": " & MyItem.LastModificationTime
Next
End Sub
The following Visual Basic for Applications example is the same as the preceding example, except it demonstrates the use of a variable in the filter.
Public Sub ContactDateCheck()
Dim DateToCheck As String
Set ol = CreateObject("outlook.application")
Set olNameSpace = ol.GetNamespace("MAPI")
Set MyContacts = olNameSpace.GetDefaultFolder(olFolderContacts).Items
DateStart = #6/11/97#
DateToCheck = "[LastModificationTime] >= """ & DateStart & """"
Set MyItems = MyContacts.Restrict(DateToCheck)
For Each MyItem In MyItems
MsgBox MyItem.FullName & ": " & MyItem.LastModificationTime
Next
End Sub
NOTE: If you are using user-defined fields as part of a Find or Restrict clause, the user-defined fields must exist in the folder; otherwise, the code generates an error stating that the field is unknown. You can add a field to a folder by displaying the Field Chooser and clicking New.
NOTE: If you receive an invalid parameter error running this code, make sure you reference the "Microsoft Outlook 98 Object Model."
