I want to display user's input data in rich text format ,thus i use TRichEdit control to fulfill it .User inputs the contents to the TRichEdit Control.I save them to Ms SQL Server database(a column whose data type is text) and then display the contents in TRichEdit control when user needs it.

I have read the RichEdit control's content to a string using TMemoryStream.but it seems that it's impossible to save to the TEXT COLUMN.

How can i do?

please mail me if you have ideas!

thanks

Alright - this is a silly question - why not use a memory stream to go the other way?

I assume you go .Loadfromstream? Then use SaveToStream to fill the TMemoryStream with the RTF and move its contents to the TEXT field in the reverse manner?

Cheers,

Raymond.

(dibs on the answer if this is it :-)

Dear rwilson:
  I have not tried the way as you said.obviously it's useless for me because I use DB-library to communicate with MS SQL Server(No querys and tables are availble, only Storedprocs and SQLs are avaible).But thanks a lot!
 as I have tried when I use plain text it's ok.I guess the reason must be the format of RichText.

w_iceberg,

I tried this :

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, Buttons, ComCtrls;

type
  TForm1 = class(TForm)
    RichEdit1: TRichEdit;
    BitBtn1: TBitBtn;
    Memo1: TMemo;
    procedure BitBtn1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.BitBtn1Click(Sender: TObject);
begin
 Memo1.lines.text := richedit1.lines.Text;
end;

end.

It gives no problems.

Can you specify your problem more?

Thanks, Zif.

w_iceberg: The RTF format is also just plain text (in that it is ASCII) there should be no real problems treating it is text for the DB field...

w_iceberg:

here's another shot. When you go to save the edited contents of the Richedit save them to a temporary file like this:

RichEdit1.PlainText := False;
RichEdit1.lines.SaveToFile('tmp.rtf');

You now has a file that is a text file containing the rtf from the control. You should be able to easily put this into your text field in the database.

Cheers,

Raymond.
