How to add rounded corners to a userform

Trying to fancy up my excel VBA userforms a little. Does anyone know how to create rounded corners on the forms?

Is there anything else you can do to make them look a little more attractive? Drop shadows etc?

Thank you for your honest opinion, and apologies for my delayed reply. I thought I had replied previously.

I had come across Leith Ross's code which rendered with the approximate beauty of Chewbacca's Backside in a thong! I also have win10, Excel 64bit, so maybe this is the issue, or maybe, just like Chewbacca's ar*e, it's never going to be pretty.

I'm a whizz with Excel, and my business runs entirely on its abilities to automate the mundane stuff. I think I'm going to have to brush up a little on the VBA before having a fully fledged system that looks as pretty as it runs. I refuse to purchase that which I can learn to design myself!
