# VAPIMWP_DRAW_DRAWPAGE

## Description

Draws a page in an area on a device context. This is a parameter of the `VAPIM_DRAW` message.

## Syntax

    #include <kvvapi.h>
    SendMessage(hWndVAPI,VAPIM_DRAW, VAPIMWP_DRAW_DRAWPAGE,
               (LPARAM) (TPVAPIDrawPageInfo*) pDrawInfo );

## Arguments

Argument | Description
--- | ---
`hWndVAPI` | The handle of the VAPI window.
`pDrawInfo` | A pointer to a TPVAPIDrawPageInfo structure that contains information used for drawing. To draw pages in any order, set the `bWait` parameter in the TPVAPIOpenDocumentInfo structure to `FALSE`.

## Returns

`SendMessage()` returns:

- `VAPI_RETURN_SUCCESS` if the call succeeds.

- `VAPI_RETURN_NOT_INITIALIZED` if the drawing routines have not been initialized.

- `VAPI_RETURN_NO_PAGE` if the requested page does not exist, or is being displayed before all previous pages have been displayed.

- `VAPI_RETURN_NOT_AVAILABLE` if the document does not support this feature (for example, ZIP files, video, audio).

- `VAPI_RETURN_ERROR` if an error has occurred.

## Discussion

- Before you send this message, initialize VAPI by sending the VAPIMWP_DRAW_INIT message, and then open the document by sending the VAPIMWP_INIT_OPEN_DOCUMENT message.

- Page numbers start at 0. For example, set `uPage` to `0` to draw page 1, and to `1` to draw page 2.

- By default, you must draw pages sequentially: to draw page 3, you must first draw pages 1 and 2. To draw pages in any order, set the `bWait` parameter in the TPVAPIOpenDocumentInfo structure to `FALSE`.
