title: Check for empty TextBox controls in VB.NET
body: <p>Ive got a Form application in VB.NET.</p>
  
  <p>I have many text boxes on one form (about 20). Is there anyway to check them all at once to see if they are empty instead of writing out a massive line of code to check each one individually such as </p>
  
  <pre><code>If txt1.text = "" Or txt2.text="" Then
      msgbox("Please fill in all boxes")
  </code></pre>
  
  <p>That just seems like a long way around it?</p>
