CRC32 User Function Library

[Paul M.]

Hello,

does anyone have either a User Function Library (or the source for
one) to create a CRC32 checksum for a given string? I want to use the
function in a crystal formula thus:

formula = CRC32("123456789")

This would then display on the report the CRC32 checksum for "123456789".

Cheers
Paul

Hi,

What CRC do you want? I have source code on my homepage that calculates the
CRC32 used for PKZip and Zmodem. However, there are other variations. It
works fine in .NET.

Hi Dick
thanks for replying I am after the (prefer VB) source code for a
Crystal User Function Library that implements the CRC32 checksum algorithm.
I think its a standard used in many places such as pkzip, data transmission.
