Is it a radio button? In OnCommand

I'm watching for messages in OnCommand, looking for BN_CLICKED and others. I need to know if the BN_CLICKED has been sent by a radio button or something else. How can I do that? I did try the following, but it wasn't successful.

BOOL CMyPage::OnCommand(WPARAM wParam, LPARAM lParam)
{
      WORD lCmdMsg = HIWORD(DWORD(wParam));
      if (lCmdMsg == BN_CLICKED)
      {
            // Was that a radio or check box button?
            CWnd *wnd = GetDlgItem(LOWORD(wParam));
            if (wnd)
            {
                  DWORD style = wnd->GetStyle();
                  if (style & BS_CHECKBOX)
                        myCBFunc(); // it's a check box
                  else if (style & BS_RADIOBUTTON)
                        myRBFunc(); // THIS NEVER GETS HIT
            }
      }
      
      return CPropertyPage::OnCommand(wParam, lParam);
}

Hi, I'm not certain, but I would try just comparing the LOWORD(wParam) to the control id of any known raido buttons. You could also compare the lParam to the HWND of the radio controls.

Maybe something like this:

if(LOWORD(wParam) == IDC_MYRADIOBTN)
      // We know this is a radio button

Or for the HWND attempt:

if((HWND)lParam == m_btnMyRadio.GetSafeHwnd())
     // Again we know this is a radio button


Also another problem is you might want to cast your GetDlgItem as a CButton (if the HIWORD(wParam) is BN_CLICKED). So like this:

          CButton *wnd = (CButton*)GetDlgItem(LOWORD(wParam));

Hope this will help,
Brandon

Thanks for the response. I can't use it though as I'm needing this for a base class that needs to work on all radio buttons.

As it turns out what I needed to do was check for BS_AUTORADIOBUTTON. Do'h!
