[VC]How To DoDataExchange, BEGIN_MESSAGE_MAP

 

目的：

讓VC物件(如 edit, combo, radio等)可自動偵測變化, 如修改文字，拉捲軸等

透過VC的宣告及DoDataExchange、BEGIN_MESSAGE_MAP方法

 

 

 

1.宣告(.h檔)

 

 

protected:

        //物件

        CEdit               m_EDIT_FLASHID0

        CLabel             m_STATIC_ERRCODE[4]; // calble物件宣告，在DoDataExchange綁定後，可直接存取物件資料，如下"ps1-1, ps1-2"

        CButton m_CHECK_AUTO;// calble物件宣告，在DoDataExchange綁定後，可直接存取物件資料，如下"ps1-1, ps1-2"

 

        //自動執行程式

        afx_msg void OnRadioToggle1();

        afx_msg void OnSelChangeComboCardSize();

        afx_msg void OnUpdateEditFLASHID0();

 

private:

        int           m_RadioSelectIniMode;//radio單選物件

 

 

 

 

2.程式執行(.cpp檔)

 

//DoDataExchange 綁定物件名 DDX_Control()、DDX_Radio()

 

void CDlgBinGrade::DoDataExchange(CDataExchange* pDX)

{

        CDialog::DoDataExchange(pDX);

 

        DDX_Radio(pDX, IDC_RADIO_AUTO, m_RadioSelectIniMode);           //物件名IDC_RADIO_AUTO

        DDX_Control(pDX, IDC_EDIT_FLASHID_0, m_EDIT_FLASHID0);      // 物件名IDC_EDIT_FLASHID_0

 

        DDX_Control(pDX, , m_EDIT_FLASHID0);     

        DDX_Control(pDX, IDC_STATIC_TITLE_PORT2, m_STATIC_TITLE_PORT[1]);               

    DDX_Control(pDX, IDC_STATIC_BB0, m_STATIC_BB[0]);

   

 

    DDX_Control(pDX, IDC_STATIC_ERRCODE_PORT1, m_STATIC_ERRCODE[0]);//ps1-1

    DDX_Control(pDX, IDC_CHECK_AUTO, m_CHECK_AUTO);   //ps1-1,

 

 

 

 

3.加進BEGIN_MESSAGE_MAP

 

//-------------------------------------------------------------------------------------------------

BEGIN_MESSAGE_MAP(CdlgSettingPage2, CDialog)

        ON_BN_CLICKED(IDC_RADIO_TOGGLE1, OnRadioToggle1) //物件名IDC_RADIO_TOGGLE1

        ON_CBN_SELCHANGE(IDC_COMBO_CARDSIZE, OnSelChangeComboCardSize) //物件名IDC_COMBO_CARDSIZE

        ON_EN_UPDATE(IDC_EDIT_FLASHID_0, OnUpdateEditFLASHID0) //物件名IDC_EDIT_FLASHID_0

        //}}AFX_MSG_MAP

END_MESSAGE_MAP()  

 

 

 

 

4.程式執行

 

//-------------------------------------------------------------------------------------------------

void CdlgSettingPage2::OnUpdateEditFLASHID0()

{

    this->m_EDIT_FLASHID0.GetWindowText(m_SPLIT_FLASH_ID.s_ID0);

        //this->m_EDIT_FLASHID0.SetWindowText("0");

}

 

 

 

//-------------------------------------------------------------------------------------------------

void CdlgSettingPage2::OnSelChangeComboCardSize()

{

        CComboBox     *pComboBox;

    int           CurSel;

    //int              nIndex;

    CString       sTmp, str;

 

    pComboBox = (CComboBox*)GetDlgItem(IDC_COMBO_CARDSIZE);

    CurSel = pComboBox->GetCurSel();

    if (CurSel == CB_ERR) {

        return;

    }

        pComboBox->GetLBText(CurSel, str);

        this->m_RDTSetting.Card_Size = atoi(str);

}

 

 

 

//-------------------------------------------------------------------------------------------------

void CdlgSettingPage2::OnRadioToggle1()

{

    GetDlgItem(IDC_COMBO_TOGGLE1)->EnableWindow(TRUE);

    GetDlgItem(IDC_COMBO_TOGGLE2)->EnableWindow(FALSE);

        this->OnSelChangeComboToggle1();

}

 

 

 

//-------------------------------------------------------------------------------------------------

void CDlgBinGrade::ShowErrorCode(IN int ItemIndex, IN int ErrorCode)//ps1-2

{

        char      Buffer[16];

        ::sprintf(Buffer, "%.4d", ErrorCode);

 

    this->m_STATIC_ERRCODE[ItemIndex].SetText(Buffer);    

}

 

 

void CDlgBinGrade::init_BinGradeEnv()//ps1-2

{

    this->m_CHECK_AUTO.SetCheck(true);

}
