title: Internet explorer automation busy v/s readystate property
body: <p>I am new to vbscript and while reading i found some code as</p>
  
  <pre><code>Do While ie.busy
  stateString = stateString &amp; " " &amp; cstr(ie.readystate)
  loop
  do while ie.readystate &lt;&gt; 4
  stateString = stateString &amp; " " &amp; ie.readystate
  loop
  </code></pre>
  
  <p>so could anyone please let me know what is difference between the busy <code>property</code> and <code>readystate</code> property.</p>
