Explorer.ViewSwitch Event (Outlook)
Occurs when the view in the explorer changes, either as a result of user action or through program code.
This Visual Basic for Applications (VBA) example hides the preview pane if it is visible when the user switches to Messages with AutoPreview view. The sample code must be placed in a class module, and the Initialize_handler routine must be called before the event procedure can be called by Microsoft Outlook.
Dim WithEvents myOlExpl As Outlook.Explorer Sub Initialize_handler() Set myOlExpl = Application.ActiveExplorer End Sub Private Sub myOlExpl_ViewSwitch() If myOlExpl.CurrentView = "Messages with AutoPreview" And myOlExpl.IsPaneVisible(olPreview) = True Then myOlExpl.ShowPane olPreview, False End If End Sub
