title: KeyPress\Up\Down doesn't work - C#
body: <p>I have this code:<br /></p>
  
  <pre><code>private void Form1_KeyDown(object sender, KeyEventArgs e)
  {
      MessageBox.Show("Fail!");
  }
  </code></pre>
  
  <p><br /></p>
  
  <p>And I've set the event in the <code>Form</code> - but it simply isn't activated.<br />
  Other events like <code>Resize</code> or <code>MouseDown</code> work well, only this doesn't work.<br /><br /></p>
  
  <p>Did someone ever experience this problem? What can I do ? [NO button works, neither characters or numerical or whatever].<br /><br />
  Thanks, Mark!</p>
