Does anyone know of a way to set the shape and fill style for the basic Winform controls?

For example, the shape of a textbox is a basic rectangular shape. I've seen one third-party control for Winforms where you can set the shape to rounded or circled, and where you can also set the fill style to horizontal/vertical fading.

Unfortunately, that product (EntrySet, from purecomponents.com) has been advertised for nine months but hasn't been released.

I'm just looking to do a few 'face-lifts' for an app, and was curious if this could be done with some intricate drawing code. As I'm typing, I just now realized I might want to check codeproject, but figured I'd ask.

TIA,
Kevin
