What would be an equivalent in VB for a simple DOS command?

copy A:*.txt c:\temp.txt
del A:*.txt

Or maybe someone can give me a hand to run such BAT file with help of Shell. the problem with Shell is that I have to wait untill Shell finished its job. But in W95/98 OS without .pif ("close on exit" properti of BAT file)file shell never finished its process without user's respond.
