Overall, I consider the whole DDX-value and DDV mechanisms to be kludges

Hey Joe thanks for replying again. I think I have gotten much of what you
have given me. Basically don't use DDX variables for direct assignment
but it is ok for DDX_Control calls. In other words if I
// From my View header file
//{{AFX_DATA(CMyAppView)
enum { IDD = IDD_MyApp_FORM };
CEdit m_EditBox;
//}}AFX_DATA

//From my View cpp file
void CMyAppView::DoDataExchange(CDataExchange* pDX)
{
CFormView::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CMyAppView)
DDX_Control(pDX, IDC_EditBox, m_EditBox);
//}}AFX_DATA_MAP
}

//Then inside the pertinant handler
  CString rString;
  m_EditBox.GetWindowText(rString);
  m_EditBox.SetWindowText(_T("555"));
// This is the best way to Set and Get the EditBox's contents, Correct?
