OL98: Do Not Use "New" Keyword to Declare New Items (192861)

SUMMARY

The Microsoft Outlook 98 object library allows you to initialize a new variable as a particular type of item, such as in the following example:

Dim MyContactItem As New Outlook.ContactItem

However, this syntax should not be supported by the object model and may cause subsequent problems in the code you are creating for a solution.

MORE INFORMATION

All items should be created using the CreateItem or Items.Add methods. The following Visual Basic for Applications example illustrates how to properly early-bind a new object variable and then set it to a new item of a specific type. Be sure to reference the Outlook 98 object library before running this code.

   Sub CreateContact()
      Dim ol As New Outlook.Application
      Dim MyContactItem As Outlook.ContactItem
      Set MyContactItem = ol.CreateItem(olContactItem)
      MyContactItem.Display
   End Sub

NOTE: Although the syntax described in the Summary section of this article may work in your solution, future versions of Outlook will not allow this syntax. A compile error will be generated before the code is run.
