Unable to find setting for exception handling in MFC

My MDI Project(VC++2010 Professional) is unable to catch errors ,though I return ,try catch block.
So I developed simple dialog based application .Placed one button on Dialog
and on its click written following code

void CMFCExecDlg::OnBnClickedButton1()
{
    try
    {
        int j = 0;
        int i = 10/j;
    }
    catch(CException * e)
    {
        MessageBox(_T("Hello"),_T(""),MB_OK);
    }
}

But still program control does not come in catch block it simply gives error.
I tried all child classes of CException but no use.I think there will be some setting in Visual Studio Please Help me for How to handle exceptions
