title: How to put a conditional breakpoint to test if a CString variable is empty
body: <p>So I have this simple code snippet:</p>
  
  <pre><code>CString str;
  ..................
  if ( str.IsEmpty() )
     str = spRelease-&gt;GetID();
  </code></pre>
  
  <p>I want to put a conditional breakpoint on the last line to test if str is empty.
  I tried this first:</p>
  
  <pre><code>str == ""
  </code></pre>
  
  <p>But I get this:</p>
  
  <pre><code>Error overloaded operator not found
  </code></pre>
  
  <p>Then this:</p>
  
  <pre><code>str.isEmpty() == 0
  </code></pre>
  
  <p>And get this:</p>
  
  <pre><code>Symbol isEMpty() not found
  </code></pre>
  
  <p>Any idee how this could be done ? Any workaround ?</p>
  
  <p>Thanks.</p>
