VBA Script in Delphi umsetzen

[BUllweih]

Das habe ich jetzt mal gemacht und die Tabelle mit den Werten vom VBA Script gefüttert.

Das Lustigste ist das es immer noch nicht geht.

Delphi-Quellcode:

var
  Form1: TForm1;
  Crc32Table            : array[0..255] of integer =
  (0,1996959894,-301047508,-1727442502,124634137,1886057615,-379345611,-1637575261,249268274,2044508324,-522852066,
