title: Efficient way to check if all textboxes are not empty
body: <p>I want to check if all the textboxes are filled before submitting the form, the way I'm doing this atm is like this:</p>
  
  <pre><code>If strGebruikersnaam &lt;&gt; String.Empty And strVoornaam &lt;&gt; String.Empty And strFamilienaam &lt;&gt; String.Empty And strEmail &lt;&gt; String.Empty And strBevestigEmail &lt;&gt; String.Empty And strWachtwoord &lt;&gt; String.Empty And strBevestigWachtwoord &lt;&gt; String.Empty And strAntispam &lt;&gt; String.Empty Then
  
      End If
  </code></pre>
  
  <p>I would like to know if there is an more efficient way to do the same thing.</p>
