BCCalcCD
ERRCODE BCCalcCD(t_BarCode *pBarCode)Calculates check-digit(s).
Calculates the check-digit(s) depending on all barcode parameters previously set (symbology, check digit method, bar code data). You can retrieve the calculated check sum with BCGetCheckDigits(). Do not change barcode parameters or input data after this call (if you want to generate a bar code).
Note
You can use this function without BCCreate() to generate check sums only (based on the bar code data).
Note
The format property and the escape sequences are not applied to the input data with this function!
Note
This function call is optional. If a check sum is adjusted or required for a bar code, it is calculated with BCCreate() also.
Note
Symbology internal check sums (e.g. Mod-103 used with Code128) are not calculated with this function. Such internal check sums are generated during BCCreate() without the need of user interaction.
