Can anyone tell me (or direct me to instructions) on how to make a button in a VB program delete the history from Netscape?

Clearing the cache and dropdown list would also be helpful. This is for a class project, and I am under a short deadline. So ANY information would be helpful. I don't even have to accomplish this with VB, so long as it can be done through a VB form (If that makes sense). Just please help if you can.

Thanks!
