Yes, I try it. But not work.

nStrCRC(mystr)

Dear Yun,

FWH provides the function nStrCrc( cString ) --> nCrc

also function nFileCrc( cFileName ) --> nCrc

Hallo Otto, nein bin nicht betroffen. Mache Software für (Schützen-)Vereine und den öffentlichen Dienst.
Liebe Grüße nach Osttirol!

Hallo Günther,
vorerst liebe Grüße aus Osttirol.
Bist du mit deiner Software von der RKSV betroffen.

Günther,

Included for next FWH version

thanks

Antonio, above function seems not included in FWH-libs for Community 2015! (FWH 16/04)

Hi!, check this link, this example and "C" program is clear!, regards. (lib_crc.zip)

OMG... I will die when tell this to my clients ...

But i understand you comment.

Thank you for the answers!

Gustavo,

Why don't you assume that all the DATA is bad and then recalculate all news CRCs using HB_CRC32() ?

Surely the CRC values between 16 and 32 bits are differents and its not easy to know where the difference comes from

Antonio, Nop, let me resume: With a simple string: "Hola" + Chr(0), i get: nStrCrc() -> Harbour + FiveWin: 254842013 nStrCrc16 -> Harbour + FiveWin: 23978 HB_CRC32 -> Harbour + FiveWin: 4040125282 nStrCrc() -> Clipper + FiveWin: 812493129 See? ...

Gustavo,

Your code nStrCrc() is like nStrCrc16() in Harbour

As far as I understand you need the same functionality between nStrCrc() in Clipper and nStrCrc16() in Harbour, and you already have it

What is it missing ?

Antonio, Test again and get the same result: Your code nStrCrc() is like nStrCrc16() in Harbour i believe the problem is that nStrCrc() is to calc the CRC16. Reading the Help of FiveWin Functions for Clipper it say: "nStrCrc( <cText> ) ... ...

Antonio, Yes!, i test your code with Clipper + FW 2.1 and get the same result that using the function nStrCrc16() with Harbour + FWh 10.12, but not the same using nStrCrc() with Clipper + FW 2.1. Or you say test only in clipper without FW ?... is same not?.. well i test all ...

Gustavo,

Please try this code with Clipper and see if it works fine,

It may be a difference between 16 and 32 bits that has to be fixed
