# VAPIMWP_INIT_SETLICENSE

Provides information about your license for the Viewing API. The license must be provided to enable other functionality, so OpenText recommends sending this message immediately after creating the window.

## Syntax

    SendMessage(hWndVAPI, VAPIM_INIT, VAPIMWP_INIT_SETLICENSE,
                    (LPARAM) (LPCSTR) pLicenseInfo);

## Arguments

Argument | Description
--- | ---
`hWndVAPI` | The handle of the VAPI window.
`pLicenseInfo` | A pointer to the license string.

## Returns

`SendMessage()` returns:

- `VAPI_RETURN_SUCCESS` if successful.
- `VAPI_RETURN_INVALID_LICENSE_KEY` if the license is invalid.
- `VAPI_RETURN_EXPIRED_LICENSE_KEY` if the license has expired.

## Discussion

If you do not provide your license information, other messages might also fail with `VAPI_RETURN_INVALID_LICENSE_KEY`.
