Shell to DOS

I want to be able to shell to DOS to pipe the contents of something to a
file which can then be read in by VB.

Example

Shell to DOS and then run ROUTE PRINT > FRED.TXT

return to VB and then open fred.txt to do sometning with that.

My attempts have so far failed as no piped file has been generated whereas
it works directly from DOS.

Hi maybe you can try it with a process:

Dim psi As New ProcessStartInfo
            Dim p As New Process

            psi.FileName = "your dos program"
            psi.WorkingDirectory = "the working directory"
            psi.WindowStyle = ProcessWindowStyle.Hidden
            psi.Arguments = "the arguments for your dos command"
            p.StartInfo = psi
            p.Start()
            p.WaitForExit()

You'll have to start "cmd" (or "%COMSPEC%") instead of your application
because the '>' feature is a feature of the command shell. You can pass the
command string to "cmd" in the command line.
