SPTEXTSELECTIONINFO

SPTEXTSELECTIONINFO combines test selection information that the SR engine can use to improve the recognition accuracy (using ISpRecoGrammar::SetWordSequenceData() and ISpRecoGrammar::SetTextSelection()).

typedef struct tagSPTEXTSELECTIONINFO
{
    ULONG       ulStartActiveOffset;
    ULONG       cchActiveChars;
    ULONG       ulStartSelection;
    ULONG       cchSelection;
} SPTEXTSELECTIONINFO;
