title: Convert a String^ to wstring C++
body: <p>I programmed a little Application in C++. There is a ListBox in the UI. And I want to use the selected Item of ListBox for an Algorithm where I can use only wstrings.</p>
  
  <p>All in all I have two questions:
  -how can I convert my </p>
  
  <pre><code>    String^ curItem = listBox2-&gt;SelectedItem-&gt;ToString();
  </code></pre>
  
  <p>to a wstring test?</p>
  
  <p>-What means the ^ in the code?</p>
  
  <p>Thanks a lot!</p>
