If you are talking about the message from Henryk Birecki, I couldnt make
heads or tails out of that.

We've had this discussion previously, and somebody actually wrote you code
to do it.

So far so good.
Please see last portion of code for what I still need to do.

void CMyDlg::OnLbnSelchangeList1()
{
int nSelect;
nSelect = c_List1.GetCurSel();
CString cSelect;
c_List1.GetText( nSelect, cSelect );

CString JobFile;
JobFile = _T("C:\\MyFolder\\"); //re-apply main part of
original path
JobFile += cSelect; //add filename selected
JobFile += _T(".txt"); //re-apply file extension

CString mess;
mess.Format(_T("Would you like to load \"%s\" as top ?"), cSelect);
int a = AfxMessageBox(mess, MB_ICONQUESTION | MB_YESNO);
if(a != IDYES)
   return;
CFile in;

if(!in.Open(JobFile, CFile::modeRead)){
   DWORD err = ::GetLastError();
   CString msg;
   msg.Format(_T("Error opening file: %d"), err);
   AfxMessageBox(msg);
   return;
}

//read entire file into string
//search string for a "keyword"
//copy x bytes from this point forward to another string
}

Please advise how to do the 3 things I need above.
The text file can be as large as 100mb and the copied portion can be as
large as 10mb.
