title: No Transparency on Visual Basic PictureBox
body: <p>I have some picture boxes on Visual Basic Express 2010, and these picture have alpha channels on them, but when the background color is set to transparent, it does not become transparent but becomes the color of the form. I still can't see anything else through the alpha map. What is the problem?
  I don't only want to see the parent object behind the picture box, but every other object that is underneath it.</p>
