title: Unable to call derived class function using base class pointers
body: <p>I want to call a derived class function that isn't defined in the base class using base class pointers. but this always raises the error:</p>
  
  <pre><code>error C2039: ‘derivedFunctionName’ : is not a member of ‘BaseClass’
  </code></pre>
  
  <p>Do you know how I could get around this?</p>
  
  <p>Thanks,</p>
