VAPIMWP_VIEW_SETPREVIEWPANE

Specifies whether the preview pane is used to display a subfile in a container file. When the preview pane is enabled, the viewing area is divided into two panes: one pane displays the contents of the container file, the other displays the contents of the selected subfile. This is a parameter of the VAPIM_VIEW message.
