Ok, I need some assistance with VB6. I have two items that I can't seem to find information on. Here is what I am needing:

1. I need to be able to determine, through VB6 itself, what the users computer is using for its default web browser. I can do it through ASP but I can't seem to determine through VB.

2. I need to know how to determine if a file is already open or not. My program has 4 separate main programs to it. I need to be able to determine how to know if any of those 4 programs are open if at all possible.

Thanks.
