How come this code won't work?

I want to display the current time in a text box. I use MFC Appwizard to create the project. Then I add an activeX control timer object to the project.
Then I used classwizard to create the class and member varible for them. But the time just isn't displayed. Please help.

Here are the code:
// timetime.cpp : Defines the class behaviors for the application.
//

#include "stdafx.h"
#include "timetime.h"
#include "timetimeDlg.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

            //    DO NOT EDIT what you see in these blocks of generated code!

      m_pMainWnd = &dlg;
      int nResponse = dlg.DoModal();
      if (nResponse == IDOK)
