MFC radio button如何默认选中

比如现在有两个 radio button，角度和弧度，我想让他默认选择弧度，怎么做？

Answer 1

到Resource View 里面 把 弧度的属性Group设置为True, 角度为False,初始化OnInitDialog的时候把弧度的radio button SetCheck()下
BOOL CXXXXDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// TODO: Add extra initialization here
m_radiohudu.SetCheck(TRUE);
m_radiojiaodu.SetCheck(FALSE);
return TRUE;
// return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}

Answer 2

CButton myButton;
myButton.SetCheck(BST_CHECKED);
