title: Is <Struct at NULL> the same as "Struct is null"?
body: <p>In Visual Studio, BuildVision gives me an Error, from which the Message is &lt; Struct <strong>at</strong> Null></p>
  
  <p>Is it the same as "Struct is Null", or is it something different?</p>
  
  <p>I'm asking because I couldn't find anything on the web with this message. All that I could find was pointing to "Struct is Null", but all I found didn't help me out! I was wondering if this is because of the <strong>at</strong>?</p>
  
  <p>Edit:</p>
  
  <p>I add a screenie of the debugger window with the &lt; Struct at Null>-Stuff.  I have a second question as well: I want to catch this exception with an if-else clause. How can I say </p>
  
  <pre><code>if(value == &lt;struct at NULL&gt;)
      this()
  else
      that()
  </code></pre>
  
  <p>This is not working, although the debugger says the value would be .</p>

  <p>In This example I try to check if components of the "distribution" are null to determine the state of the Distribution object. Here is the origianl code:</p>
  
  <pre><code>if (Distribution.distBrowserName() == NULL || Distribution.getShape() == NULL)
          return false;
      else 
          return true;
  </code></pre>
