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.
#include <kvvapi.h> SendMessage(hWndVAPI, VAPIM_VIEW, VAPIMWP_VIEW_SETPREVIEWPANE, (LPARAM) (BOOL) bNewValue );
| Argument | Description |
|---|---|
hWndVAPI

bNewValue
|
A flag that returns TRUE or FALSE, depending on whether the preview pane was set. Only container files use the preview pane. |
SendMessage() returns TRUE if the call succeeds, in which case bNewValue returns TRUE or FALSE.SendMessage() returns FALSE if the call fails (for example, if there are invalid arguments or if no document is open), in which case bNewValue is undefined.|
