MFC复选框的使用

1.创建关联变量，并给初始值

在BOOL CDialogDlg::OnInitDialog()中创建关联，并给默认值

//给复选框创建关联变量,并给默认值

    pCheck1 = (CButton*)GetDlgItem(IDC_CHECK1);

    pCheck2 = (CButton*)GetDlgItem(IDC_CHECK2);

    pCheck3 = (CButton*)GetDlgItem(IDC_CHECK3);

    pCheck4 = (CButton*)GetDlgItem(IDC_CHECK4);

    pCheck1->SetCheck(1);

2.读取复选框的状态

//复选框

void CDialogDlg::OnButton2() 

{

    // TODO: Add your control notification handler code here

    CString str;

    m_CheckState = 0;

    m_CheckState += pCheck1->GetCheck();

    m_CheckState +=(pCheck2->GetCheck());

    m_CheckState +=(pCheck3->GetCheck());

    m_CheckState +=(pCheck4->GetCheck());

    str = '0'+m_CheckState;

    MessageBox(str);

    

}
