Step 3

///////////////////////////////////////////////////////////
// CMyFindDlg dialog

class CMyFindDlg : public CFindReplaceDialog
{
// Construction
public:
 
 // standard constructor
 CMyFindDlg(CWnd* pParent = NULL);   

// Dialog Data
 //{{AFX_DATA(CMyFindDlg)>
 enum { IDD = IDD_MYFINDDLG };
 // NOTE: the ClassWizard will add data members here
 //}}AFX_DATA


// Overrides
 // ClassWizard generated virtual function overrides
 //{{AFX_VIRTUAL(CMyFindDlg)
 protected:
 virtual void DoDataExchange(CDataExchange* pDX);    
 //}}AFX_VIRTUAL

// Implementation
protected:

 // Generated message map functions
 //{{AFX_MSG(CMyFindDlg)
 afx_msg void OnCheck1();
 //}}AFX_MSG
 DECLARE_MESSAGE_MAP()
};

Step 4

///////////////////////////////////////////////////////////
// CMyFindDlg dialog

CMyFindDlg::CMyFindDlg(CWnd* pParent /*=NULL*/)
 : CFindReplaceDialog()
{
 //{{AFX_DATA_INIT(CMyFindDlg)
  // NOTE: the ClassWizard will add member 
  // initialization here
 //}}AFX_DATA_INIT
}

Step 5

///////////////////////////////////////////////////////////
// CMyFindView message handlers

void CMyFindView::OnMyFind() 
{
 m_pMyFindDialog= new CMyFindDlg();

 m_pMyFindDialog->m_fr.lpTemplateName =
  MAKEINTRESOURCE(IDD_MYFINDDLG);

 m_pMyFindDialog->Create(TRUE,
                         NULL,
                         NULL,
                         FR_ENABLETEMPLATE | FR_HIDEUPDOWN,
                         this);
 m_pMyFindDialog->SetActiveWindow();
 m_pMyFindDialog->ShowWindow(TRUE);
 // TODO: Add your command handler code here
}

Where m_pMyFindDialog is defined in MyFindView.h

CMyFindDlg* m_pMyFindDialog;

Step 6

static UINT FindReplaceDialogMessage = 
 ::RegisterWindowMessage(FINDMSGSTRING);

ON_REGISTERED_MESSAGE(FindReplaceDialogMessage, 
                      OnFindReplaceMessage)

Here is the Find/Replace dialog message handler function:

LRESULT CMyFindView::OnFindReplaceMessage(WPARAM wParam, 
                                          LPARAM lParam)
{
 CFindReplaceDialog* pFindReplace = 
  CFindReplaceDialog::GetNotifier(lParam);

 ASSERT(pFindReplace != NULL);

 if (pFindReplace->IsTerminating())
 {
  pFindReplace = NULL;
 }
 else if (pFindReplace->FindNext())
 {
  if(FindText(pFindReplace->GetFindString(),
              FALSE,
              FALSE))
   AdjustDialogPosition(pFindReplace);
  else
   TextNotFound(pFindReplace->GetFindString());
 }

 return 0;
}
