title: Decrease form opacity
body: <p>When I click on <code>Button1</code>, if <code>Form1((me))</code> opacity is less than 90 then <code>Form1's((me))</code> opacity should decrease by 9%</p>
  
  <p>This is my code </p>
  
  <pre><code>Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
      If Me.Opacity &gt; 90 Then
          Me.Opacity = -9
      End If
  End Sub
  </code></pre>
  
  <p>and it's not working</p>
