ReadNumeric 

Overview

When True the toolkit will only report numeric barcodes. Note that this the same as setting the Pattern property to the value "^[0-9]+$".

Default Value: False

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

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

e.g

// Read only numeric barcodes.
#include "barcode.h"
uint16 value = 1 ;
STSetParameter(hBarcode, ST_NUMERIC_BARCODE, &value) ;
