title: Check which mouse button was "upped"
body: <p>Well, I have an event handler for when a mouse button is up. I want to check which button was (left or right). This is the function definition:</p>
  
  <pre><code> Private Sub PictureBox2_MouseUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox2.MouseUp
  </code></pre>
  
  <p>I used</p>
  
  <pre><code>    e.Button.Left()
  </code></pre>
  
  <p>to try to get a boolean, but I get an error....</p>
