title: Using an image including semi-transparent parts as background of a form?
body: <p>It has been like 4 years I'm having this problem. I kept trying to create a round shaped form. The edges were always messed up. Then I tried to create an image in desired shape and put it in a picturebox and set the background color of the form to green. Then I selected transparency key of the form to green. Again no luck... Now I have this image:</p>
  <p><img src="https://i.stack.imgur.com/s3BcM.png" alt="the image" /></p>
  <p>Here is what I always get when I try to use it as a &quot;form&quot;.</p>
  <p><img src="https://i.stack.imgur.com/eAjSF.png" alt="enter image description here" /></p>
  <p>I don't want to give up since I know it is not impossible, I always see, for example the options windows of games, have that kind of image as a form. So, any solution?</p>
