expression An expression that returns an Explorer object declared with events in a class module.

The following Microsoft Visual Basic/Visual Basic for Applications (VBA) example prompts the user before pasting the contents of the Clipboard to the specified target. If the user clicks Yes, the current content in the Clipboard is copied to the specified target destination. The sample code must be placed in a class module such as ThisOutlookSession, and the Initialize_handler routine must be called before the event procedure can be called by Outlook.
Public WithEvents myOlExp As Outlook.Explorer
Sub Initalize_Handler()
Set myOlExp = Application.ActiveExplorer
End Sub
Private Sub myOlExp_BeforeItemPaste(ClipboardContent As Variant, ByVal Target As MAPIFolder, Cancel As Boolean)
Dim lngAns As Integer 'users' answer
'Prompt user about paste
lngAns = MsgBox("Are you sure you want to paste the contents of the clipboard into the " _
& Target.Name & "?", vbYesNo)
If lngAns = vbNo Then
Cancel = True
End If
End Sub
