Steps:

1. Load sample diagram at running:

// Parse command line for standard shell commands, DDE, file open
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

// Dispatch commands specified on the command line
if (cmdInfo.m_nShellCommand == CCommandLineInfo::FileNew)
{
CString strPathX = AfxGetApp()->m_pszHelpFilePath;
strPathX = strPathX.Left(strPathX.ReverseFind('\\'));
CString strOtherFile;
strOtherFile = strPathX+_T("\\usamap.map");
this->OpenDocumentFile(strOtherFile);
}
else if (!ProcessShellCommand(cmdInfo))
{
return FALSE;
}

2. Showing pan window at left side:

if (!m_wndPanBar.Create(this, _T("Pan Window"), WS_CHILD|WS_VISIBLE|CBRS_LEFT|CBRS_TOOLTIPS|CBRS_SIZE_DYNAMIC|CBRS_FLOAT_MULTI, 
CBRS_FOP_DEFAULT|CBRS_FOP_BDSP, 20002))
{
TRACE(_T("Failed to create List Bar\n"));
return -1;
}

DockControlBarEx(&m_wndPanBar, AFX_IDW_DOCKBAR_LEFT, 50, 200);

LRESULT CMainFrame::OnViewValidMsg (WPARAM wparam, LPARAM lp)
{
	lp;
	CFODrawView* pView = (CFODrawView*) wparam;
	
	m_wndPanBar.SetActiveView(pView);

	return 1;
}

LRESULT CMainFrame::OnViewInValidMsg (WPARAM wparam, LPARAM lp)
{
	CFODrawView* ActiveView = (CFODrawView*) wparam;
	CFODrawView* DeactiveView = (CFODrawView*) lp;

	// VERY important change, handling the case when switch to othe app.
	if(ActiveView == DeactiveView) 
		return 1;

	if (m_wndPanBar.GetActiveView()==DeactiveView)
	  m_wndPanBar.SetActiveView(NULL);

	return 1;
}

LRESULT CMainFrame::OnShapeChangedMsg(WPARAM wP,LPARAM /*lP*/)
{
	m_wndPanBar.UpdateWnd(FALSE);
	return TRUE;
}

LRESULT CMainFrame::OnCanvasChangedMsg(WPARAM wP,LPARAM lP)
{
	int nLong = (int)lP;
	if(nLong == 100)
	{
		m_wndPanBar.UpdateWnd(TRUE);
		m_wndPanBar.RedrawWindow();
	}
	else
	{
		m_wndPanBar.UpdateWnd(FALSE);
	}
	return TRUE;
}

3. Draw composite shape on the canvas call:


void CMapDemoView::OnFoMapItem1() 
{
	// TODO: Add your action handler code here
	if(m_drawshape == FO_COMP_COMPOSITE && m_nCurShapeResID == IDR_COMPSRES1)
	{
		m_action_state = State_SelectNone;
		m_drawshape = FO_COMP_NONE;
		FOSetSystemCursor(IDC_ARROW);
		return;
	}
	StartCustomShapeID(IDR_COMPSRES1);
	AddShapePort(0.5,0.5);
}

void CMapDemoView::OnUpdateFoMapItem1(CCmdUI* pCmdUI) 
{
	// TODO: Add your action update UI handler code here
	BOOL bDesign = GetCurrentModel()->IsDesignMode();
	pCmdUI->Enable(bDesign);

	pCmdUI->SetCheck(m_drawshape == FO_COMP_COMPOSITE && m_nCurShapeResID == IDR_COMPSRES1);

}

void CMapDemoView::OnFoMapItem2() 
{
	// TODO: Add your action handler code here
	if(m_drawshape == FO_COMP_COMPOSITE && m_nCurShapeResID == IDR_COMPSRES2)
	{
		m_action_state = State_SelectNone;
		m_drawshape = FO_COMP_NONE;
		FOSetSystemCursor(IDC_ARROW);
		return;
	}
	StartCustomShapeID(IDR_COMPSRES2);
	AddShapePort(0.5,0.5);
}

void CMapDemoView::OnUpdateFoMapItem2(CCmdUI* pCmdUI) 
{
	// TODO: Add your action update UI handler code here
	BOOL bDesign = GetCurrentModel()->IsDesignMode();
	pCmdUI->Enable(bDesign);

	pCmdUI->SetCheck(m_drawshape == FO_COMP_COMPOSITE && m_nCurShapeResID == IDR_COMPSRES2);

}

4. Initial the view:

void CMapDemoView::DoChangeModel(CFODataModel * pModel)
{
	CSize szCanvas = CSize(1000,1000);
	pModel->SetCanvasSize(szCanvas);
}

void CMapDemoView::OnInitialUpdate()
{
	SetCurrentModel(GetDocument()->m_pDataModel);
	CFODrawView::OnInitialUpdate();
	GetCurrentModel()->SetBorderShow(FALSE);

	UpdateScrollBarSize();
	ZoomToFitPageWidth();
}
