Process - no window open

Hi,

I have a C# (form) program. I need it to run a 'command line program'. I
have it working fine using Process, but it (temporarily) opens a Command
Prompt window everytime it runs (and closes it when it finishes).

How do I get it to run in the background without opening a window each time
I call process.Start()? (FYI: I searched for this on the web but couldn't
find anything)

Thanks,

Hilton

This vb fragment works for me and also reads back stdout of the launched
process. I'm not sure how much of this is really necessary - I stopped
experimenting when I got it to work.

Dim s As String
Dim p As New Process
With p.StartInfo
.FileName = "whatever.exe"
.Arguments = "arg1 arg2"
.UseShellExecute = False
.RedirectStandardError = True
.RedirectStandardInput = True
.RedirectStandardOutput = True
.WindowStyle = ProcessWindowStyle.Hidden
.CreateNoWindow = True
End With
Try
p.Start()
s = p.StandardOutput.ReadToEnd()
p.WaitForExit()
Catch e As Exception
s = e.tostring
End Try
