Steps:

1.Create a new class CExtDataModel that use CFODataModel as base class.

2. Add the following codes within the header file of dialog:

CFOPDrawWnd m_wndCanvas;
CExtDataModel * m_pDataModel;

// Toolbox wnd.
CFOMultiToolBoxWnd m_wndTool;

// Attributes
CFOListItemObjList m_Shapes;

// Load resource file.
virtual void LoadFromFile();

// Find item with id.
// nIndex -- the id of item.
virtual CFOListItemObj *FindObjByID(int nIndex);

// Do create toolbox pages.
virtual void DoCreatePages();

virtual BOOL ContinueModal();

3. Add the following codes to create the canvas and toolbox window:
// TODO: Add extra initialization here
m_pDataModel = new CExtDataModel;

CRect theRect;
GetDlgItem(IDC_CANVAS)->GetWindowRect( &theRect );
ScreenToClient(&theRect);

// m_wndClock.Create(WS_CHILD|WS_VISIBLE|WS_BORDER,theRect, this,1001);
DWORD dwStyle = WS_CHILD|WS_VISIBLE|WS_BORDER|WS_TABSTOP;

m_wndCanvas.SetCurrentModel(m_pDataModel);
m_wndCanvas.Create(dwStyle, theRect,this,IDC_CANVAS);
CRect rcClient;
m_wndCanvas.GetClientRect(&rcClient);

m_wndCanvas.SetVirtualOrigin(0, 0);
m_wndCanvas.SetVirtualSize(1000, 1000);

m_wndTool.Create(WS_CHILD|WS_VISIBLE|WS_TABSTOP|WS_EX_CLIENTEDGE,CRect(0,0,100,100),this,IDC_TOOLBOX);

// Do create toolbox pages.
DoCreatePages();

GetDlgItem(IDC_TOOLBOX)->GetWindowRect( &theRect );
ScreenToClient(&theRect);

m_wndTool.SetWindowPos( NULL, theRect.left, theRect.top, theRect.Width(), theRect.Height(),
SWP_NOZORDER|SWP_NOACTIVATE );

4. Call actions like the following codes:

void CDialogTestDlg::OnDrawEllipse() 
{
	// TODO: Add your command handler code here
	m_wndCanvas.OnFOPFoDrawEllipse();
}

void CDialogTestDlg::OnUpdateDrawEllipse(CCmdUI* pCmdUI) 
{
	// TODO: Add your command update UI handler code here
	m_wndCanvas.OnFOPUpdateFoDrawEllipse(pCmdUI);
}

void CDialogTestDlg::OnFileOpen() 
{
	// TODO: Add your command handler code here
	static CString szFilter = _T("Test Dialog file(*.tdf)|*.tdf|");

	CFileDialog fileDlg(TRUE, _T(".tdf"), "", OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,szFilter, NULL);

	if (fileDlg.DoModal() != IDOK)
		return;
	
	CString m_lstfilename = fileDlg.GetPathName();
	m_wndCanvas.OpenDocument(m_lstfilename);
}

void CDialogTestDlg::OnUpdateFileOpen(CCmdUI* pCmdUI) 
{
	// TODO: Add your command update UI handler code here
	pCmdUI;
}

void CDialogTestDlg::OnFileSave() 
{
	// TODO: Add your command handler code here
	static CString szFilter = _T("Test Dialog file(*.tdf)|*.tdf|");

	CFileDialog fileDlg(FALSE, _T(".tdf"), "Test.tdf", OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,szFilter, NULL);

	if (fileDlg.DoModal() != IDOK)
		return;
	
	CString m_lstfilename = fileDlg.GetPathName();
	
	m_wndCanvas.SaveDocument(m_lstfilename);
}

void CDialogTestDlg::OnPageSetup() 
{
	// TODO: Add your command handler code here
	if(m_wndCanvas.OnFOPPageSetup())
	{
		m_wndCanvas.DoUpdateScrollBars();
	}
	
}

void CDialogTestDlg::OnUpdatePageSetup(CCmdUI* pCmdUI) 
{
	// TODO: Add your command update UI handler code here
	pCmdUI;
}

BOOL CDialogTestDlg::ContinueModal()
{
	if (m_wndCanvas.m_bPrintPreview)
		// send WM_IDLEUPDATECMDUI message to update toolbar state
		// This is normally called by OnIdle function in SDI or MSI applications.
		// Dialog based applications don't call OnIdle, so send the message from here instead
		AfxGetApp()->m_pMainWnd->SendMessageToDescendants(WM_IDLEUPDATECMDUI,
		(WPARAM)TRUE, 0, TRUE, TRUE);
	
	return CDialog::ContinueModal();
}

void CDialogTestDlg::OnFilePrint() 
{
	// TODO: Add your command handler code here
	m_wndCanvas.DoPrint();
}

BOOL CAboutDlg::OnInitDialog() 
{
	CDialog::OnInitDialog();
	
	// TODO: Add extra initialization here
	GetDlgItem(IDC_EDIT1)->SetWindowText(_T("If you want to learn more about E-XD++ Diagrammer Library Enterprise Edition,Visit:http://www.ucancode.net"));

	return TRUE;  // return TRUE unless you set the focus to a control
	              // EXCEPTION: OCX Property Pages should return FALSE
}

void CDialogTestDlg::OnFilePrintPreview() 
{
	// TODO: Add your command handler code here
	m_wndCanvas.PrintPreview();
}
