[TranslateDispatch is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

Used by the client of the DoReaderMode function to intercept and explicitly handle any windows messages targeted for the scrolling area of the reader mode window. This is an application-defined callback function.

Syntax

BOOL CALLBACK TranslateDispatch(
  _In_ const MSG *lpmsg
);

Parameters

lpmsg [in]

Type: const MSG*

A pointer to an MSG structure that contains the intercepted message.

Return value

Type: BOOL

TRUE if the message was handled by this function; otherwise, FALSE. If FALSE, the message is handled by the default reader mode implementation. That implementation handles mouse movement and buttons as well as key presses.

Examples

The following example outlines an implementation of this function.

BOOL CALLBACK
TranslateDispatchCallback(LPMSG lpmsg)
{
    BOOL fResult = FALSE;

    if (lpmsg->message == WM_KEYDOWN)
    {
        
        // Perform custom keyboard actions here.
        fResult = TRUE;
    }

    return fResult;
}
