How can I mix pictures with text in a RichText Control in Visual C++ using MFC? I tried using the PasteSpecial Method but it didn't work.

Ok, here is some code... try it out and see how it works...
===========UNIT1.H==============
//---------------------------------------------------------------------------
#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;
//---------------------------------------------------------------------------
#endif
=============UNIT1.CPP===================
//---------------------------------------------------------------------------
#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)
{
    OldWndProc(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
    bmp->LoadFromFile("C:\\windows\\desktop\\test.bmp");
}
//---------------------------------------------------------------------------
void __fastcall TForm1::FormDestroy(TObject *Sender)
{
    delete bmp;
}
//---------------------------------------------------------------------------
