title: How to make the selected testcript is run in selenium grid
body: <p>I need a help.........</p>
  
  <p>I can launch some remote control by using: 
  ant launch-remote-control</p>
  
  <p>but I dont know how my script connect to hub?
  I set up ant, selenium-grid on the same computer.
  I have an grid.dll which is written by C# and run through NUnit.
  The test data is read from xml file (ValidData.xml)
  The example code is below :</p>
  
  <p>using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using System;
  using System.Xml;
  using System.Text.RegularExpressions;
  using System.Threading;
  using NUnit.Framework;
  using Selenium;</p>
  
  <p>namespace Grid
  {
      public class Class1
      {
          //User defined</p>
  
  <pre><code>    private string strURL = "http://gmail.com/";
      private string[] strBrowser = new string[3] { "*iehta", "*firefox", "*safari" };
     string hubAddress = "192.168.20.131"; // IP of my computer
  
      // System defined
      private ISelenium selenium;
      private StringBuilder verificationErrors;
  
      [SetUp]
      public void SetupTest()
      {
  
          selenium = new DefaultSelenium(hubAddress, 4444, this.strBrowser[1], this.strURL);// do i need to identify browser when I defined it when launching a remote control
          selenium.Start();
          verificationErrors = new StringBuilder();
      }
  
      [TearDown]
      public void TeardownTest()
      {
          try
          {
              selenium.Stop();
          }
          catch (Exception)
          {
              // Ignore errors if unable to close the browser
          }
          Assert.AreEqual("", verificationErrors.ToString());
      }
  
      private string[] name;
  
      [Test]
      public void LoginPassedTest()
      {
          try
          {
              XmlDocument doc = new XmlDocument();
              XmlNode docNode;
  
              doc.Load("ValidData.xml");
              docNode = doc["TestCase"];
  
              foreach (XmlNode node in docNode)
              {
                  selenium.Open("/");
                  selenium.WaitForPageToLoad("50000");
                  selenium.Type("Email", node["username"].InnerText);
                  selenium.Type("Passwd", node["password"].InnerText);
                  selenium.Click("signIn");
                  selenium.WaitForPageToLoad("100000");
                  name = (selenium.GetText("//div[@id='guser']/nobr/b").Split('@'));
  
                  try
                  {
                      Assert.AreEqual(node["username"].InnerText, name[0]);
                      Assert.AreEqual("Sign out", selenium.GetText(":r6"));
                  }
                  catch (AssertionException e)
                  {
                      verificationErrors.Append(e.Message);
                  }
  
                  selenium.Click(":r6");
              }
          }
          catch (AssertionException e)
          {
              verificationErrors.Append(e.Message);
          }
      }
  }

  <p>Step I run this script:
  1.I build that script into DLL
  2.I start hub by using command "ant lauch-hub"
  3.I start 2 remote controls by using command :
        ant -Dport=5566 -Denvironment="*chrome" launch-remote-control
        ant -Dport=5577 -Denvironment="*iexplore" launch-remote-control
  4.Then I open Nunit and load DLL (code above) and run
  5.The NUNit doesnot respond anything.</p>
  
  <p>I think there are some missing things but I dont know.
  How can the test script (DLL) know which is sequence of remote control is selected to run the test????</p>
  
  <p>Please help me!!
  Thank you so much</p>
  
  <p>Yui.</p>
