Drawing complex shapes onto a form. (.net)

I have a control that looks similar to the following:

I need to add slightly round ends where all that extra end space is. I'm not sure how to add these. It sho开发者_如何学Pythonuld look similar to the round ends on this page. (At the top)

Thanks!

A few years late ... but this may be the answer to your question.

Provide the parameters from your code to draw the rectangles and away you are!
