Handle WM_KEYDOWN message and inside the message check the key pressed is enter.

void CMyTree::OnKeyDown(   UINT nChar,   UINT nRepCnt,   UINT nFlags )
{
  if( nChar == VK_RETURN )
  {
       // The key pressed is enter. Do you processing
  }

You can use of CTreeCtrl::GetItemText for get string of an item.

Did you see MSDN see an example of MSDN:

HTREEITEM hCurSel = m_TreeCtrl.GetNextItem(TVI_ROOT, TVGN_CARET);

// report it to the user
if (hCurSel == NULL)
{
AfxMessageBox(_T("There is no selected item"));
}
else
{
CString str;
str.Format(_T("The currently selected item is \"%s\""),
(LPCTSTR)m_TreeCtrl.GetItemText(hCurSel));
AfxMessageBox((LPCTSTR)str);
}

Given a stack S and a queue Q, write a program in OOP (C++)that have 2 procedures FILLQ_WITHS will empty the contents of the stack S and insert them into the Queue Q and FillS_WithQ which will fill the stack S with the elements deleted from the queue Q. Impliment the procedure with S and having an array representation.
