Text and binary in one stream? | Shortcuts?

[WojTec]

Hello guys!

# begin streams

I need to save and read many data types (numbers (int, float), records, arrays and strings) in one file. Problem is with strings. Currently I'm using TStringStream:

Example write:

Delphi-Quellcode:

Buffer := Length(AValue);
AStream.Write(Buffer, 4);

AString.Clear;
AString.WriteString(AValue);

AStream.CopyFrom(AString, 0);

Example read:

Delphi-Quellcode:

Strings := TStringStream.Create;
try
  P := AStream.Position;
  AStream.Position := 0;
  Strings.CopyFrom(AStream, FHeaderSize);
  AStream.Position := P;

  for I := 1 to 8 do
  begin
    AStream.Position := P;
    AStream.Read(buff32, 4);

    Strings.Position := AStream.Position;
    buffS := Strings.ReadString(buff32);

    // ...

    AStream.Position := Strings.Position;
    P := AStream.Position;
  end;
finally
  Strings.Free;
end;

1st at all strings inside file are not Unicode (compiled on D2010). How to make it unicode?
2nd: my method looks very lame, is better method to store strings next to the binary data?

# end streams

# begin shortcuts

2nd my problem is with shortcuts in dynamically created menu items:

Delphi-Quellcode:

if Item.Tag in [1..9] then
  Item.ShortCut := ShortCut(48 + Item.Tag, [ssCtrl, ssAlt])
;

When press Ctrl+Alt+[num 1-9] program starts executing OnClick for ever... Why?

# end shortcuts

First you need a nice protocol/file format to encode and decode all these data types.
Bencode could be such a protocol.
If you want to store unicode strings i suggest to read and write the strings as UTF8.

I see that strings are stored as ANSI and don't know how to change encoding :(
