//使用方法
、Dlg类中添加变量
public:
CToolTipWnd m_BalloonToolTip;
//Dlg::OnInitDialg()添加初始化代码
、添加气球式提示栏
m_BalloonToolTip.Create(this);
m_BalloonToolTip.AddTool(GetDlgItem(IDC_ENABLE_BTN),"禁止/允许面板走纸按键", RGB

(255,0,0));

3、 Dlg::PreTranslateMessage(MSG* pMsg) 添加代码
 if(m_BalloonToolTip)
    m_BalloonToolTip.RelayEvent(pMsg);
  return CDialog::PreTranslateMessage(pMsg);


二 添加按钮 IDC_ENABLE_BTN
1,rc文件中BEGIN END之间添加
PUSHBUTTON      "禁止按键",IDC_ENABLE_BTN,119,83,46,16,BS_FLAT
2,Dlg::DoDataExchange(CDataExchange* pDX)添加
DDX_Control(pDX, IDC_ENABLE_BTN, m_btnEnable);
3,BEGIN_MESSAGE_MAP(*Dlg, CDialog)中添加点击消息
    ON_BN_CLICKED(IDC_ENABLE_BTN, OnEnableBtn)
   Dlg::OnEnableBtn() {}

4,设置按钮内容
SetDlgItemText(IDC_ENABLE_BTN,"允许按键");
Resource.h添加
#define IDC_ENABLE_BTN                  1007

三 CListBox添加
Dlg类的AFX_DATA中添加
CListBox    m_ctlList;
Dlg::DoDataExchange(CDataExchange* pDX)的//{{AFX_DATA_MAP()中添加
    DDX_Control(pDX, IDC_LIST_ANY, m_ctlList);
使用
 m_ctlList.InsertString(-1,"连接打印机失败...");
rc文件添加listbox
  LISTBOX         IDC_LIST_ANY,13,54,91,152,LBS_SORT |
                    LBS_NOINTEGRALHEIGHT | WS_VSCROLL | WS_TABSTOP
Resource.h文件中添加
    #define IDC_LIST_ANY                    1004
四,显示和隐藏右边界面
添加按钮
 #define IDC_SETDIP_BTN                  1010
 PUSHBUTTON      "设置DIP",IDC_SETDIP_BTN,188,141,46,16,BS_FLAT
dlg类中定义并AFX_DATA_MAP中 绑定变量
    CButton    m_btnSetdip;
DDX_Control(pDX, IDC_SETDIP_BTN, m_btnSetdip);
BEGIN_MESSAGE_MAP 添加点击消息
ON_BN_CLICKED(IDC_SETDIP_BTN, OnSetdipBtn)
添加消息OnSetdipBtn
    static BOOL bExpand = TRUE;
    ExpandDialog(IDC_DIVIDER, bExpand);
    bExpand = !bExpand;   
Dlg::ExpandDialog(int nResourceID, BOOL bExpand)
{
    static CRect rcLarge;
    static CRect rcSmall;
    CString sExpand;

    if(rcLarge.IsRectNull())
    {
       CRect rcLandmark;
       CWnd* pWndLandmark = GetDlgItem(nResourceID);
       ASSERT(pWndLandmark);
       GetWindowRect(rcLarge);
       pWndLandmark->GetWindowRect(rcLandmark);
       rcSmall = rcLarge;
       rcSmall.right = rcLandmark.left;
    }
    if(bExpand)
    {
         SetWindowPos(NULL, 0, 0, rcLarge.Width(), rcLarge.Height(),
         SWP_NOMOVE | SWP_NOZORDER);
         sExpand = "设置DIP<<";
    }
    else
    {
        SetWindowPos(NULL, 0, 0, rcSmall.Width(), rcSmall.Height(),
        SWP_NOMOVE | SWP_NOZORDER);
        sExpand = "设置DIP>>";
    }
    SetDlgItemText(IDC_SETDIP_BTN, sExpand);
}
rc中picture Properties IDC_DIVIDER 添加
  CONTROL         "",IDC_DIVIDER,"Static",SS_BLACKFRAME,257,7,170,205
#define IDC_DIVIDER                     1034
使用 ExpandDialog(IDC_DIVIDER, bExpand);

五 添加COMBOBOX
1, rc文件中添加 COMBOBOX        IDC_COMBO_PORT,44,17,44,58,CBS_DROPDOWNLIST |
                    CBS_UPPERCASE | WS_VSCROLL | WS_TABSTOP,
                    WS_EX_DLGMODALFRAME
    #define IDC_COMBO_PORT                  1000
添加 列表
//
// Dialog Info
//

IDD_POS2000DEMO_DIALOG DLGINIT
BEGIN
    IDC_COMBO_PORT, 0x403, 5, 0
0x4f43, 0x314d, "\000"

    IDC_COMBO_BAUD, 0x403, 6, 0
0x3833, 0x3034, 0x0030,
END
Dlg::DoDataExchange(CDataExchange* pDX) 绑定变量
DDX_CBIndex(pDX, IDC_COMBO_PORT, m_Port);
消息函数BEGIN_MESSAGE_MAP(
ON_CBN_SELCHANGE(IDC_COMBO_PORT, OnSelchangeComboPort)

5使其无效GetDlgItem(IDC_COMBO_BAUD)->EnableWindow(false);
