How to run DOS CMD Command Prompt commands from VB NET

Question

The question is self-explanatory  It would be great if the code was one line long  something to do with  Process Start            I researched the web but only found old examples and such ones that do not work  at least for me   I want to use this in my class library  to run Git commands  if that helps

I was inspired by Steve s answer but thought I d add a bit of flare to it  I like to do the work up front of writing extension methods so later I have less work to do calling the method   For example with the modified version of Steve s answer below  instead of making this call     MyUtilities RunCommandCom  DIR     W   true   I can actually just type out the command and call it from my strings like this     Directly in code   Call  CD  APPDATA   amp  TREE  RunCMD    OR  From a variable   Dim MyCommand    CD  APPDATA   amp  TREE  MyCommand RunCMD     OR  From a textbox   textbox text RunCMD WaitForProcessComplete  True     Extension methods will need to be placed in a Public Module and carry the  lt Extension gt  attribute over the sub  You will also want to add Imports System Runtime CompilerServices to the top of your code file   There s plenty of info on SO about Extension Methods if you need further help     Extension Method  Public Module Extensions      lt summary gt      Extension method to run string as CMD command       lt  summary gt       lt param name  command  gt  String  Command to run  lt  param gt       lt param name  ShowWindow  gt  Boolean  Default False  Option to show CMD window  lt  param gt       lt param name  WaitForProcessComplete  gt  Boolean  Default False  Option to wait for CMD process to complete before exiting sub  lt  param gt       lt param name  permanent  gt  Boolean  Default False  Option to keep window visible after command has finished  Ignored if ShowWindow is False  lt  param gt   lt Extension gt  Public Sub RunCMD command As String  Optional ShowWindow As Boolean   False  Optional WaitForProcessComplete As Boolean   False  Optional permanent As Boolean   False      Dim p As Process   New Process       Dim pi As ProcessStartInfo   New ProcessStartInfo       pi Arguments         If ShowWindow AndAlso permanent    K     C           command     pi FileName    cmd exe      pi CreateNoWindow   Not ShowWindow     If ShowWindow Then         pi WindowStyle   ProcessWindowStyle Normal     Else         pi WindowStyle   ProcessWindowStyle Hidden     End If     p StartInfo   pi     p Start       If WaitForProcessComplete Then Do Until p HasExited   Loop End Sub End Module

Imports System IO Public Class Form1     Public line  counter As String     Private Sub Button1 Click sender As Object  e As EventArgs  Handles Button1 Click         counter    1         If TextBox1 Text      Then             MsgBox  Enter a DNS address to ping           Else              line     start    vbNewLine              line     ping     TextBox1 Text              MsgBox line              Dim StreamToWrite As StreamWriter             StreamToWrite   New StreamWriter  C  Desktop Ping    counter     bat               StreamToWrite Write   start    vbNewLine                                      Ping -t     TextBox1 Text              StreamToWrite Close               Dim p As New System Diagnostics Process               p StartInfo FileName    C  Desktop Ping    counter     bat              p Start           End If     End Sub End Class   This works as well
