title: Return type in findById method, control could not be found by id
body: <p>I'm writing a VBA script that read some values from a SAP procedure (ME23N).</p>
  
  <p>I'm using findById method to read some values but I dont know if the object extists or not.</p>
  
  <pre><code>Session.findById("wnd[0]/usr/sub/.......).Text
  </code></pre>
  
  <p>I'd like to know what findById method returns if the provided id does not exists. Knowing that I can handle this situation and avoid "The control could not be found by id" runtime message.</p>
  
  <p>Is there a public SAP documentation where I can find some informations?</p>
  
  <p>Thanks in advance</p>
