This Microsoft Visual Basic/Visual Basic for Applications example shows how to call the OnStatusChange method to notify Microsoft Outlook that the user has changed a value on a custom property page.
Private Sub Option1_Click()
Dim myPPSite As Outlook.PropertyPageSite
Set myPPSite = Parent
globNewUserType = globAdministrator
If globUserType <> globNewUserType Then
globDirty = True
End If
myPPSite.OnStatusChange
End Sub
