Automatic date in userform

Hi,
I've created a userform and want one textbox to automatically enter today's date but in the form dd/mm/yyyy as opposed to the mm/dd/yyyy form it's in by default.
Please help!
oh and there will probably be a lot more pleas for help. I'm doing work experience and my boss has got me creating this form despite me telling him time and time again that I've never done any programming or anything like that in my life!
THANKS
