  System.Diagnostics.Process Question

  Mar 05, 2003 04:51 PM|LINK

  I have a System.Diagnostics.Process that I would like to call upon a shell application (ipconfig). I want to then gather the ipconfig information in a variable. Is there a way to do this? Here is what I have so far:

  Imports System
  
  
  Public Class Machine
      Dim myProcess As New System.Diagnostics.Process()
  
  
      Function IPConfig() As String
          Dim myConfig As String
  
  
          myProcess.StartInfo.RedirectStandardOutput = True
          myProcess.StartInfo.UseShellExecute = True
          myProcess.StartInfo.FileName = "ipconfig.exe"
          myProcess.StartInfo.Arguments = "/all"
          myConfig = myProcess.StandardOutput.ReadToEnd
  
  
          Return myConfig
      End Function
  
  
  End Class

  The error I am getting is this: System.InvalidOperationException: StandardOut has not been redirected. at System.Diagnostics.Process.get_StandardOutput() at Machine.MacAddress(String ipAddress) Does anyone have a clue?
