how do i pass Switches to a dos program?

how do i pass Switches(commands) to a dos program?

VB Code:

Shell "command.com /c dir /a C:\Windows\*.* > C:\Windows.txt", 1

Doesn't this work?

VB Code:

Shell "c:\dosprogram.exe /command", vbNormalFocus

looks like I waited a second too long before pressing that submit button..
