Radio按钮状态在对话框间的传递问题

[wgf42421]

[CODE=C/C++] CModal Dlg;
if (Dlg.DoModal()==IDOK)
{
m_nRadio = Dlg.m_nRadio;
}
switch (m_nRadio)
{
case 1:
((CButton*)GetDlgItem(IDC_RADIO1))->SetCheck(1);
break;
case 2:
((CButton*)GetDlgItem(IDC_RADIO2))->SetCheck(1);
break;
case 3:
((CButton*)GetDlgItem(IDC_RADIO3))->SetCheck(1);
break;

}
[/CODE]
radio按钮分组了,从Dlg.DoModal()进入回来2次后发现有3个radio按钮被可以选中.怎么解决?
我本意只是想让Dlg.DoModal中的radio按钮的check状态传递给当前窗口的radio按钮.

[写不动代码的人]

CModal Dlg;
if (Dlg.DoModal()==IDOK)
{
m_nRadio = Dlg.m_nRadio;
}
((CButton*)GetDlgItem(IDC_RADIO1))->SetCheck(0);
((CButton*)GetDlgItem(IDC_RADIO2))->SetCheck(0);
((CButton*)GetDlgItem(IDC_RADIO3))->SetCheck(0);
switch (m_nRadio)
{
case 1:
((CButton*)GetDlgItem(IDC_RADIO1))->SetCheck(1);
break;
case 2:
((CButton*)GetDlgItem(IDC_RADIO2))->SetCheck(1);
break;
case 3:
((CButton*)GetDlgItem(IDC_RADIO3))->SetCheck(1);
break;

}

在按钮的响应函数里面, 比如IDC_RADIO1对应的响应函数里面添加处理就可以了:
void CModal OnRadio1()
{
((CButton*)GetDlgItem(IDC_RADIO1))->SetCheck(1);
((CButton*)GetDlgItem(IDC_RADIO2))->SetCheck(0);
((CButton*)GetDlgItem(IDC_RADIO3))->SetCheck(0);
}

其他两个响应函数也这样做, 就不会出现可以同时选中了
