read specific output off a System.Diagnostics.Process

[josephine]

G'day all

below is a CMD screen shot, of a file Upload to an IBM IS390 Mainframe,
via Command Prompt window (CMD.exe is s must, as .NET Class FTPWebRequest, doesnt cater for IBM IS390 Mainframe Authentication.).

H:\>ftp
ftp> OPEN 188.66.122.110
Connected to 188.66.122.110.

ftp> BYE

VB code for the Process (should read p.output, into a msgbox):

Dim p As System.Diagnostics.Process
        Dim pwrite As New ProcessStartInfo
        Dim output As String, sr As StreamReader
        pwrite.UseShellExecute = False
        pwrite.CreateNoWindow = False  'True = no window
        pwrite.RedirectStandardOutput = True  '= no output to read--> can create a problem
        pwrite.FileName = "cmd.exe"
        pwrite.Arguments = "/K ftp -n -s:autoftp.txt"
        Try
            MsgBox("ok to start process")
            p = Process.Start(pwrite)
            output = p.StandardOutput.ReadToEnd
            While Not p.HasExited
                p.Refresh()
                Thread.Sleep(100)
                output = output & p.StandardOutput.ReadToEnd
            End While
            MsgBox("Success Upload")
            MsgBox("output: " & vbNewLine & output)
        Catch ex As Exception
            MsgBox(ex.Message)
        Finally
            MsgBox("got to finally, Closing Process!")
            If Not p Is Nothing Then
                p.Close()
            End If
        End Try

RESULT:
msgbox pops, showing the text in "AutoFTP.txt" script.

TODO:
how to read output to ensure successfull upload?? (2 red lines in cmd..)


thanks in advance for any suggestion.

Happy Friday
