Two ways

Child Dialog gets apointer to the parent
Parent calls function in the Child Dialog

class CMyDialog :
  CString m_csData;
  CDialog m_pParent;
  SetParent ( CDialog* pParent ) { m_pParent = pParent; }

  OnSend ( ..   // IDC_SEND Button
     myEdit.GetWindowText( csData );
     if ( m_pParent ) // Either do this directly
        m_pParent->id_latlon = csData; //better to have function

   GetData () { return m_csData; }

  CParentDlg parentDlg;

  CMyDialog myDlg;
  myDlg->SetParent ( &parentDlg );
  myDlg.DoModal ();


  CParentDlg parentDlg;

  CMyDialog myDlg;
  myDlg.DoModal ();

  parentDlg->id_latlon = myDlg->GetData ()

CCalibrate::CCalibrate(CWnd* pParent /*=NULL*/)

this is my OnSend

void CCalibrate::OnSend()
this is to execute to send data to parent dialog CScrollBitmapDlg::CScrollBitmapDlg

  When CCalibrate is Created pass in the CScrollBitmapDlg as the parent... You see the parent is being set to NULL above.

  Send the code of the classes

  then in OnSend
  void CCalibrate::OnSend ()
    ((CScrollBitmapDlg*)GetParent ())->id_latlon = data;
