创建VS2010/MFC工程

在dialog上拖入控件 Picture Control ID 为 IDC\_DISPLAY 放到徐要切割的部分

放置按钮 命名 "收缩<<"

void CCComDlg::OnBnClickedIncise()
    {
    	// TODO: Add your control notification handler code here
    	CString	str;
    	static CRect RectLarge;
     	static CRect RectSmall;
    	if(GetDlgItemText(IDC_INCISE,str) && str == _T("展开>>"))
    	{
    			SetDlgItemText(IDC_INCISE,_T("收缩<<"));
    	}
    	else
    	{
    			SetDlgItemText(IDC_INCISE,_T("展开>>"));
    	}
    	if(RectLarge.IsRectNull())
    	{
     		CRect RectChang;		
     		GetWindowRect(&RectLarge);		//原始尺寸
     		GetDlgItem(IDC_DISPLAY)->GetWindowRect(RectChang);    //获取切断位置
     		
    		RectSmall.top = RectLarge.top;
     		RectSmall.left= RectLarge.left;
     		RectSmall.right = RectChang.right;
     		RectSmall.bottom = RectLarge.bottom;
    
     	}
     	if(str == _T("展开>>"))
     	{
    		SetWindowPos(NULL,0,0,RectLarge.Width(),RectLarge.Height(),SWP_NOMOVE | SWP_NOZORDER);
     	}
     	else
     	{
     		SetWindowPos(NULL,0,0,RectSmall.Width(),RectSmall.Height(),SWP_NOMOVE | SWP_NOZORDER);
     	}
    }

在OnInitDialog()函数中添加

BOOL CCComDlg::OnInitDialog()
    {
    	CDialogEx::OnInitDialog();
    
    	// Add "About..." menu item to system menu.
    
    	// IDM_ABOUTBOX must be in the system command range.
    	ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
    	ASSERT(IDM_ABOUTBOX < 0xF000);
    
    	CMenu* pSysMenu = GetSystemMenu(FALSE);
    	if (pSysMenu != NULL)
    	{
    		BOOL bNameValid;
    		CString strAboutMenu;
    		bNameValid = strAboutMenu.LoadString(IDS_ABOUTBOX);
    		ASSERT(bNameValid);
    		if (!strAboutMenu.IsEmpty())
    		{
    			pSysMenu->AppendMenu(MF_SEPARATOR);
    			pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
    		}
    	}
    
    	// Set the icon for this dialog.  The framework does this automatically
    	//  when the application's main window is not a dialog
    	SetIcon(m_hIcon, TRUE);			// Set big icon
    	SetIcon(m_hIcon, FALSE);		// Set small icon
    
    	// TODO: Add extra initialization here
    	OnBnClickedIncise(); //进行切割  隐藏示波器 保留串口
    
    	return TRUE;  // return TRUE  unless you set the focus to a control
    }
