title: How create an object of a Class from a string that holds the name of that class?
body: <p>Let's say I have a string with my class name inside:    </p>
  
  <pre><code>mystring = "CDialogChild";
  </code></pre>
  
  <p>I would like to create an object of the type name written in my string.
  I'd like to do something like:</p>
  
  <pre><code>CDialogParent dlg = CDialogParent(mystring);
  </code></pre>
  
  <p>My new dlg is now created as type CDialogChild and I can use its methods:</p>
  
  <pre><code>dlg.mycdialogchild_method();
  </code></pre>
