Re: How to handle CListBox and member variable?

If I in the class header declare a member for a CListBox control in my
dialog like

public:
 'CListBox m_lb;'

the Studio creates a call in the '::DoDataExchange(CDataExchange* pDX)'
function like this:

 DDX_Control(pDX, IDC_Kinder, m_lb);

Later in OnInitDialog() I try to change the font of the listbox to an
earlier (in the constructor of the dialog class) created CFont pointed to
by 'CFont* m_pFon' with a statement like this:

 m_lb.SetFont( m_pFon, TRUE );

This produces a runtime error. What am I doing wrong?

I think if Joseph M. Newcomer guessed to

 '... forget that you have ever heard of a function called GetDlgItem ...'

it must be possible to do the job with a member variable of type CListBox,
not this way:

 CListBox* plb = (CListBox*)GetDlgItem( IDC_Kinder );
 plb->SetFont( m_pFon, TRUE ); // This works!
