//使用方法
1 、Dlg类中添加变量
public:
CToolTipWnd m_BalloonToolTip;
//Dlg::OnInitDialg()添加初始化代码
2 、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");
5 Resource.h添加
#define IDC_ENABLE_BTN 1007
三 CListBox添加
1 Dlg类的AFX_DATA中添加
CListBox m_ctlList;
2 Dlg::DoDataExchange(CDataExchange* pDX)的//{{AFX_DATA_MAP()中添加
DDX_Control(pDX, IDC_LIST_ANY, m_ctlList);
3 使用
m_ctlList.InsertString(-1,"连接打印机失败...");
4 rc文件添加listbox
LISTBOX IDC_LIST_ANY,13,54,91,152,LBS_SORT |
LBS_NOINTEGRALHEIGHT | WS_VSCROLL | WS_TABSTOP
5 Resource.h文件中添加
#define IDC_LIST_ANY 1004
四，显示和隐藏右边界面
1 添加按钮
#define IDC_SETDIP_BTN 1010
PUSHBUTTON "设置DIP",IDC_SETDIP_BTN,188,141,46,16,BS_FLAT
2 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);
3 BEGIN_MESSAGE_MAP 添加点击消息
ON_BN_CLICKED(IDC_SETDIP_BTN, OnSetdipBtn)
4 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);
}
6 rc中picture Properties IDC_DIVIDER 添加
CONTROL "",IDC_DIVIDER,"Static",SS_BLACKFRAME,257,7,170,205
#define IDC_DIVIDER 1034
7 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
2 添加 列表
//
// Dialog Info
//
IDD_POS2000DEMO_DIALOG DLGINIT
BEGIN
IDC_COMBO_PORT, 0x403, 5, 0
0x4f43, 0x314d, "\000"
IDC_COMBO_PORT, 0x403, 5, 0
0x4f43, 0x324d, "\000"
IDC_COMBO_PORT, 0x403, 5, 0
0x4f43, 0x334d, "\000"
IDC_COMBO_PORT, 0x403, 5, 0
0x544c, 0x3150, "\000"
IDC_COMBO_PORT, 0x403, 5, 0
0x544c, 0x3250, "\000"
IDC_COMBO_BAUD, 0x403, 5, 0
0x3639, 0x3030, "\000"
IDC_COMBO_BAUD, 0x403, 6, 0
0x3931, 0x3032, 0x0030,
IDC_COMBO_BAUD, 0x403, 6, 0
0x3833, 0x3034, 0x0030,
0
END
3 Dlg::DoDataExchange(CDataExchange* pDX) 绑定变量
DDX_CBIndex(pDX, IDC_COMBO_PORT, m_Port);
4 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);
