Before a new document is opened, this frees up any data from a previously opened document. This is a parameter of the `VAPIM_DRAW` message.

## Syntax

    SendMessage(g_hWndVAPI, VAPIM_DRAW, DRAW_SHUTDOWN, 0L );

## Arguments

Argument | Description
--- | ---
`g_hWndVapi` | The handle of the VAPI window
`uMsg` | `VAPIM_DRAW`
`wParam` | `VAPIMWP_DRAW_SHUTDOWN`
`lParam` | Not used, set to `0`

## Returns

`SendMessage()` returns:

- `VAPI_RETURN_SUCCESS` (or `TRUE`, value `1`) if the call succeeds.
- `VAPI_RETURN_NOT_INITIALIZED` (value `5`) if the drawing routines have not been initialized.
- `VAPI_RETURN_ERROR` (or `FALSE`, value `0`) if the call fails.

## Discussion

`VAPIM_DRAW` messages are used in the sample `drawdemo` program.
