[VS 2005] Passing a command to the command line

Hey guys, I just started with VB, and I'm wondering if I can pass along this command:

copy /b file.ext + file.ext file.ext

to the command line. I've tried Shell() and Process.Start, but nothing seems to work :(. Is there a function in VB that's like system() in C++?

And, if possible, could I use a function instead of passing that command to the command line?

Thanks guys.
