Re: MFC: adding a control into a dialog window

What I do in these cases is create a list as a member of the parent.
Then I can create, show/hide, delete or whatever needs to be done
without having a magic fixed number of controls at compile time.

For example:

// NOTE: CControl is fictitious

typedef list<CControl *> CONTROLLIST;

/////////////////////////////////////////////////////////////////////
class CMyDialog : public CDialog
{
..
..
..
     CONTROLLIST m_ControlList;
     CONTROLLIST::iterator m_ControlIterator;

..
..
};

// To add a new control

void CMyDialog::AddControl()
     {
     CControl *pNewControl;
     pControlNode = new CControl();

     if (pNewControl)
         m_ControlList.insert(m_ControlList.end(), pNewControl);
     else
         AfxMessageBox("Control creation failed!\n");
     }

// Similar approach for deleting, etc.
