I am attempting to output command prompt data to a listview, which works but im having a few issues.  The command prompt window never exits to load the data to the listview, i have to click X and then it closes and loads the info to the listview.  When it does load it to listview, it doesnt separate the info out into 2 separate columns which i have created in the listview properties:


Dim psi As New ProcessStartInfo("cmd.exe")
        psi.Arguments = String.Concat(" /K systeminfo /S ", Form1.TextBox1.Text)
        psi.RedirectStandardOutput = True
        psi.WindowStyle = ProcessWindowStyle.Hidden
        psi.UseShellExecute = False


        Dim pExec As New Process()
        pExec = Process.Start(psi)

        Dim output As StreamReader = pExec.StandardOutput
        pExec.WaitForExit()

        If pExec.HasExited Then
            Dim line As String
            Do
                line = output.ReadLine()
                If Not line Is Nothing Then
                    ListView1.Items.Add(line)
                End If
            Loop Until line Is Nothing
            output.Close()
        End If

Open in new window

It's because you are not parsing the line into it's separate components.  To the listview a string is just a string, but a complex class is something entirely different.

Secondly, the process window is doing what you are telling it to do, start a new process and wait for the process window to close (not wait till the process itself has finished).
