ShowCheckDigit 

Overview

When set to TRUE the OCX will include the barcode check digit in the returned string. 

Note: This property only applies to barcode types with built in check digits (e.g Code 128).   

Default value =     FALSE

void STSetParameter(hBarcode, ST_SHOW_CHECK_DIGIT, uint16 *value) ;

void STGetParameter(hBarcode, ST_SHOW_CHECK_DIGIT, uint16 *value) ;

e.g

// Return check digits with the barcode string
#include "barcode.h"
uint16 value = 1 ;
STSetParameter(hBarcode, ST_SHOW_CHECK_DIGIT, &value) ;
