Datei inhalt als HEX-String ausgeben...

[toms]

Hallo

P. Below (Team B) hat mal eine solche Funktion geschrieben:

Delphi-Quellcode:

type
  TDisplayProc = procedure(const s: string) of object;

procedure ShowBinary(var Data; Count: Cardinal; DispProc: TDisplayProc);

implementation


procedure ShowBinary(var Data; Count: Cardinal; DispProc: TDisplayProc);
var
  line: string[80];
  i: Cardinal;
  p: PChar;
  nStr: string[4];
const
  posStart = 1;
  binStart = 7;
  ascStart = 57;
  HexChars: PChar = '0123456789ABCDEF';
begin
  p    := @Data;
  line := '';
  for i := 0 to Count - 1 do
  begin
    if (i mod 16) = 0 then
    begin
      if Length(line) > 0 then
        DispProc(line);
      FillChar(line, SizeOf(line), ' ');
      line[0] := Chr(72);
      nStr    := Format('%4.4X', [i]);
      Move(nStr[1], line[posStart], Length(nStr));
      line[posStart + 4] := ':';
    end;
    if p[i] >= ' ' then
      line[i mod 16 + ascStart] := p[i]
    else
      line[i mod 16 + ascStart] := '.';
    line[binStart + 3 * (i mod 16)]     := HexChars[(Ord(p[i]) shr 4) and $F];
    line[binStart + 3 * (i mod 16) + 1] := HexChars[Ord(p[i]) and $F];
  end;
  DispProc(line);
end;


procedure TForm1.Display(const S: string);
begin
  Memo1.Lines.Add(S);
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  ms: TMemoryStream;
begin
  if Opendialog1.Execute then
  begin
    ms := TMemoryStream.Create;
    try
      ms.LoadFromfile(OpenDialog1.FileName);
      ShowBinary(ms.Memory^, ms.Size, Display);
    finally
      ms.Free
    end;
  end;
end;
