        p.StartInfo.FileName = "Write500Lines.exe"  
        p.Start() 

        ' To avoid deadlocks, always read the output stream first and then wait.  
        Dim output As String = p.StandardError.ReadToEnd()  
        p.WaitForExit()

        Console.WriteLine($"{vbCrLf}Error stream: {output}")
    End Sub
