Private Sub expression_BeforeItemCopy(Cancel As Boolean)
expression An expression that returns an Explorer object declared with events in a class module.
Cancel Required Boolean. False when the event occurs. If the event procedure sets this argument to True, the operation is not completed and the item is not copied.
Example
The following Microsoft Visual Basic/Visual Basic for Applications (VBA) example prompts the user before an item is copied. A message is displayed to the user verifying that the item should be copied. If the user clicks Yes, the item is copied to the Clipboard. 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 Microsoft Outlook.
Public WithEvents myOlExp As Outlook.Explorer
Sub Initalize_Handler()
Set myOlExp = Application.ActiveExplorer
End Sub
Private Sub myOlExp_BeforeItemCopy(Cancel As Boolean)
'Prompts the user before copying an item
Dim lngAns As Long 'user answer
'Display question to user
lngAns = MsgBox("Are you sure you want to copy the item?", vbYesNo)
If lngAns = vbYes Then
Cancel = False
Else
'Set Cancel argument based on answer
Cancel = True
End If
End Sub
