Hi,

I have a dialog box with 2 radio buttons. i have a code like this.

CMyDlg::CMyDlg(CWnd* pParent )
: CDialog(CMyDlg::IDD, pParent)
{ }

CMyDlg::~CMyDlg()
{ }

void CMyDlg::DoDataExchange(CDataExchange* pDX)
{
   CDialog::DoDataExchange(pDX);

  DDX_Control(pDX, IDC_A, m_AButton); //CButtom m_AButton
  DDX_Control(pDX, IDC_B, m_BButton); //CButton m_BButton

}

BEGIN_MESSAGE_MAP(CMyDlg, CDialog)

ON_BN_CLICKED(IDC_A, OnA)
ON_BN_CLICKED(IDC_B, OnB)

END_MESSAGE_MAP()

BOOL CMyDlg::OnInitDialog()
{
   m_AButton.EnableWindow(TRUE);
   m_BButton.SetCheck(TRUE);
}

In this case i want that a function should be invoked every time the
statement m_AButton.SetCheck(TRUE); is executed.
How can i do this.

Thanks in advance.

I don't know of a way to arrange for this; in my code, after I call
m_BButton.SetCheck(), I insert

OnB();

to make sure the handler is called after this programatic change of B. I'm
not sure why MFC does not do this for us, but it doesn't.
