title: User defined type not defined on Snapshot and Database
body: <p>I am using vb6 but following did not work at all:</p>
  
  <pre><code>Dim Sn as Snapshot
  Dim db as Database
  </code></pre>
  
  <p>Each statement generates an error. </p>
  
  <pre><code>USER DEFINED TYPE NOT DEFINED
  </code></pre>
  
  <p>Any suggestions are highly appreciated. </p>
