// CSample5Dialog
//
// CSample5Dialog is based on the IDD_DLGSAMP5 dialog template.
// I have dragged an user control into the dialog template and
// set the control class to "GXWnd".
//
// In OnInitDialog I call the SubclassDlgItem member funtion
// which subclasses the CWnd control:
//    m_wndGrid.SubclassDlgItem(IDC_GRIDWND5, this);
//
// After calling SubclassDlgItem, the user control is attached
// to the m_wndGrid member variable. m_wndGrid is an instance
// of the CSample5GridWnd class. OnInitDialog calls the
// Initialize method to initialize the grid.
//
// In DoDataExchange, I have added the line
// DDV_GXGridWnd(pDX, &m_wndGrid);
// which enables control validation in the dialog.
