How to copy RTF text to a TMemo via a TStringStream

Answer:

Here is a method to copy the formatted text to a memo via a stringstream. The same 
approach should work to store it in a database field that takes a string.
1   
2   procedure TForm1.Button1Click(Sender: TObject);
3   var
4     ss: TStringStream;
5   begin
6     ss := TStringStream.Create(EmptyStr);
7     try
8       richedit1.plaintext := false;
9       richedit1.lines.savetostream(ss);
10      memo1.text := ss.DataString;
11    finally
12      ss.free;
13    end;
14  end;
15  
16  procedure TForm1.Button2Click(Sender: TObject);
17  var
18    ss: TStringStream;
19  begin
20    ss := TStringStream.Create(memo1.text);
21    try
22      richedit1.plaintext := false;
23      richedit1.lines.LoadFromstream(ss);
24    finally
25      ss.free;
26    end;
27  end;


To simply copy formatted text from a TRichEdit to a string, you could also use:
28  
29  function GetRawRTFText(aRichedit: TRichedit): string;
30  var
31    SS: TStringstream;
32  begin
33    SS := TStringstream.Create(EmptyStr);
34    try
35      aRichedit.plaintext := False;
36      arichedit.Lines.SaveToStream(SS);
37      Result := SS.DataString;
38    finally
39      SS.Free
40    end;
41  end;
