var strMap = null;
var index = 0;

function AddStrMap(str)
{
  if (strMap == null)
      strMap = m_Map.GetUtility().GetStrStringMap();
    
  strMap.InsertItem(String(index),  str);
  alert("Total Count :" strMap.GetItemCount());
  
  index = Number(index);
  index = index + 1;
}

function DelStrMap(key)
{
  if (strMap.FindItemValue(key) != null)
  {
    strMap.DeleteItem(key);
  }
}

준비중입니다...
