title: How can I insert values at map to list pair?
body: <p>My container is like this:</p>
  
  <pre><code>map&lt;DWORD, list&lt;pair&lt;string,LARGE_INTEGER&gt;&gt;&gt; map_to_list_items;
  </code></pre>
  
  <p>This code fails to compile:</p>
  
  <pre><code>map&lt;DWORD, list&lt;pair&lt;string,LARGE_INTEGER&gt;&gt;&gt;::iterator iter_map_to_list_items = map_list_items.find(dwThreadID);
  if ( iter_map_to_list_items == map_to_list_items.end() )
  {
      map_to_list_itens.insert ( pair&lt;DWORD,pair&lt;string,LARGE_INTEGER&gt;&gt;(dwTheadID, (string("Start"), m_TimePRE)));
  }
  </code></pre>
