event BeforeSelChanged (OldFolder as ExShellFolder, NewFolder as ExShellFolder, Cancel as Boolean)
Fired before a folder is selected.

TypeDescription
OldFolder as ExShellFolder A Folder being un-selected.
NewFolder as ExShellFolder A Folder being selected.
Cancel as Boolean A Boolen expression that indicates whether the operation is executed or canceled.
This event is fired before the current selection is changed. Setting the Cancel parameter to True prevents the selection from being changed. The NewFolder parameter lets you know which folder will become selected if you do not cancel the selection change and the OldFolder parameter lets you know which folder is currently selected. The SelectedFolder property indicates the selected folder, at runtime. The control fires the AfterSelChanged event after the user changes the selection.
