MFC编辑框的使用

编辑框的提取

在使用是控件时，设置属性为多行垂直滚动，这样可避免文字的滚动

1.在void CDialogDlg::OnChangeEdit1()

void CDialogDlg::DoDataExchange(CDataExchange* pDX)
{
    CDialog::DoDataExchange(pDX);
    //{{AFX_DATA_MAP(CDialogDlg)
        // NOTE: the ClassWizard will add DDX and DDV calls here
    //}}AFX_DATA_MAP

    DDX_CBString(pDX,IDC_EDIT1,m_edite1);
}

2.在此编辑框的消息响应函数中读取

void CDialogDlg::OnChangeEdit1() 
{
    // TODO: If this is a RICHEDIT control, the control will not
    // send this notification unless you override the CDialog::OnInitDialog()
    // function and call CRichEditCtrl().SetEventMask()
    // with the ENM_CHANGE flag ORed into the mask.
    
    // TODO: Add your control notification handler code here
    //获取编辑框内容方式1 
//        GetDlgItem(IDC_EDIT1)->GetWindowText(m_edite1);   
    //获取编辑框内容方式2
//    GetDlgItemText(IDC_EDIT1,m_edite1);
}

2.如何给编辑框关联变量，如何让编辑框显示文本

//获得EDIT

CEdit* pBoxOne;

pBoxOne = (CEdit*) GetDlgItem(IDC_EDIT1);

//付值

pBoxOne->SetWindowText( _T"FOO" );

//取值

CString str;

pBoxOne->GetWindowText(str);

GetDlgItem(IDC_EDIT1)->SetWindowText( _T"FOO" );

也可以

//取值

CString str;

GetDlgItem(IDC_EDIT1)->GetWindowText(str);
