If nothing else, at least this line:
Hr=m_pConnection - & gt; Open (" provider=SQLOLEDB; Data Source=IDEA - PC \ SQLEXPRESS; Initial catalog=eye electronic medical records system; Integrated Security=SSPI;" , ""," ", adModeUnknown);

Should be changed to:

 hr=m_pConnection - & gt; Open (" provider=SQLOLEDB; Data Source=IDEA - PC \ \ SQLEXPRESS; Initial catalog=eye electronic medical records system; Integrated Security=SSPI;" , ""," ", adModeUnknown);
