Ok, here is some code... try it out and see how it works...
#ifndef Unit1H
#define Unit1H
#include <Classes.hpp>
#include <Controls.hpp>
#include <StdCtrls.hpp>
#include <Forms.hpp>
#include <ComCtrls.hpp>
class TForm1 : public TForm
__published:      // IDE-managed Components
    TRichEdit *RichEdit1;void __fastcall FormCreate(TObject *Sender);void __fastcall MyWndProc(TMessage &Message);
    void __fastcall FormDestroy(TObject *Sender);
private:      // User declarations
public:            // User declarations
    __fastcall TForm1(TComponent* Owner);
extern PACKAGE TForm1 *Form1;
#include <vcl.h>
#pragma hdrstop
#include "Unit1.h"
#pragma package(smart_init)
#pragma resource "*.dfm"

TForm1 *Form1;

TWndMethod OldWndProc;
Graphics::TBitmap *bmp;

__fastcall TForm1::TForm1(TComponent* Owner)
    : TForm(Owner)
void __fastcall TForm1::MyWndProc(TMessage &Message)
    if (Message.Msg == WM_PAINT) {
        TCanvas *MyCanvas = new TCanvas;
        MyCanvas->Handle = GetDC(RichEdit1->Handle);
        BitBlt(MyCanvas->Handle, 0, 0, bmp->Width, bmp->Height, bmp->Canvas->Handle, 0, 0, SRCCOPY);
        ReleaseDC(RichEdit1->Handle, MyCanvas->Handle);
        delete MyCanvas;

void __fastcall TForm1::FormCreate(TObject *Sender)
    OldWndProc = RichEdit1->WindowProc;
    RichEdit1->WindowProc = MyWndProc;
    bmp = new Graphics::TBitmap;
 //You MUST have a file on the desktop in order for it to work
void __fastcall TForm1::FormDestroy(TObject *Sender)
    delete bmp;

Hope this helps...
