￭ Note

If the

barcode data within the code (excluding the check digit positions) contains any

characters outside the character set corresponding to the barcode type specified by the

check digit type, this function returns "0" and throws an exception. However, if only the

check digit positions contain a character outside the valid character set, then

this function

calculates the correct check digit and returns it as a single-character string.

[VB] Scanner.GetChkDigit("494AB4458", "A")

[C#] Scanner.GetChkDigit("494AB4458", "A")

Since "A" and "B" lie outside the valid character set for EAN (JAN) or UPC, "0" is returned

and an exception is thrown.

[VB] Scanner.GetChkDigit("4940045X", "A")

[C#] Scanner.GetChkDigit("4940045X", "A");

"X" lies outside the valid character set but is in the CD position, and therefore the correct

CD (ASCII "8") is calculated and returned.

[VB] Scanner.GetChkDigit("a0ef3-a", "N")

[C#] Scanner.GetChkDigit("a0ef3-a", "N");

Since "e" and "f" lie outside the valid character set for Codabar (NW-7), "0" is returned and

an exception is thrown.

[VB] Scanner.GetChkDigit("a123Qa", "N")

[C#] Scanner.GetChkDigit("a123Qa", "N");

"Q" lies outside the valid character set but is in the CD position, and therefore the correct

CD (ASCII "-") is calculated and returned.
