Looks to me like you're trying to hook your result array (the bools) to the
control variable. You didn't show the type, but I'd assume since you called
it m_bCheckBoxesArray that they are type bool and they should be type
CCheckBox if you are trying to hook them into a control (or at least a
CWnd ).

Dear all

I have an array of checkboxes and wanted to connect them to an array
of bool
variables.
So I added: DDX_Control(pDX, IDC_CHECK1a, m_bCheckBoxesArray[0][0]);
and so
on...
( in void CGraphDialog::DoDataExchange(CDataExchange* pDX)
{
   CDialog::DoDataExchange(pDX);
   //{{AFX_DATA_MAP(CChartDemoDlg)
   // Add this line with the appropriate ID and variable name
   DDX_Control(pDX, IDC_ChartCtrl1, m_ChartCtrl);
   DDX_Control(pDX, IDC_ChartCtrl2, m_ChartCtrl2);
   DDX_Control(pDX, IDC_ChartCtrl3, m_ChartCtrl3);
   DDX_Control(pDX, IDC_CHECK1a, m_bCheckBoxesArray[0][0]);
   //}}AFX_DATA_MAP
})

I got the following compiler error:

error C2664: 'DDX_Control' : cannot convert parameter 3 from 'bool'
to
'class CWnd &'
       A reference that is not to 'const' cannot be bound to a non-
lvalue

Could anybody please help me?

Thanks...
