# VAPIMWP_MULTIOBJ_NEXTOBJ

Changes the current object to the next object in a multiple-object document. See Change the Current Object in a Document. This is a parameter of the `VAPIM_MULTIOBJ` message.

## Syntax

    #include <kvvapi.h>
    SendMessage(hWndVAPI, VAPIM_MULTIOBJ, VAPIMWP_MULTIOBJ_NEXTOBJ, 0L );

## Arguments

Argument | Description
--- | ---
`hWndVAPI` | The handle of the VAPI window.

## Returns

`SendMessage()` returns `TRUE` if the current object was changed to the next object; otherwise it returns `FALSE`.

## Discussion

You can use this message to implement a Next Object menu item or toolbar button. This message generates a `VAPINMWP_MULTIOBJ_OBJNAME` notification message that reports the new object name.

When viewing spreadsheets or presentations in index mode, this message fails if the next page is not completely indexed yet, or if the current page is the last page. In other words, the program does not allow the last page to wrap around to the first page, as it does in non-index mode.
