title: Textbox null problem
body: <p>I have a textbox and a button on my Access form. In the click event of the button i want to see if the textbox is empty, if it is, nothing will be executed.
  So i use </p>
  
  <pre><code>If Me.textbox.Value = Null Then
      Exit Sub
  End if
  </code></pre>
  
  <p>But it doesn't work... I checked the textbox.value in the execution window and it is Null, but the if clause just doesn't work... Why? </p>
  
  <p>EDIT: @Dimse, I tried "", doesn't work. And also textbox.text = Null, it pops an error telling me the textbox is not active.. Very strange.</p>
