Question

I have to start a process in a cmd window.
But in cases like shown because of some error cmd window just flashes and I can’t see what happens. It would be the best if cmd window stay opened until some keypress or similar.

Dim q As String = Chr(34)
Dim p As New Process
With p.StartInfo
      .FileName = q & whereis7z & "\7z.exe" & q
      .Arguments = " e " & q & tempArch & fNameStr & q & " -y"
      .WindowStyle = ProcessWindowStyle.Normal
      .CreateNoWindow = False
      .WorkingDirectory = tempArch
       Debug.Print(.FileName & .Arguments)
End With
p.Start()
If p.ExitCode <> 0 Then
       MsgBox(p.ExitCode, MsgBoxStyle.Critical)
End If

Is here any way to keep cmd window opened until keypress to see what’s wrong with my ‘StartInfo’ because ‘ExitCode’ is not enough.

Alternatively, you could redirect the standard output of the window in order to capture the program output.

p.StartInfo.RedirectStandardOutput = True

Then just read in what the program has output so you can display it yourself,

Dim Output as String = p.StandardOutput.ReadToEnd
