the problem is in the remed out part where the radio button data exchange occurs

//transfer check box info
void CSampleDialog::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Check(pDX, IDD_CB1, m_check1Val);
DDX_Check(pDX, IDD_CB2, m_check2Val);
//DDX_Radio(pDX, IDD_RB1, m_radio1Val);
//DDX_Radio(pDX, IDD_RB2, m_radio2Val);
}

it crashes in this function.. I have no idea what to do

I treated the DDX_radio function just like the DDX_Check function
