asp.net c# webservice consumed by flex

Someone on the flexcoders asked to be provided with a simple example of flex consuming an asp.net webservice. I know this might be VERY simple, but it proves functionality.

ASP.NET Webservice in C#

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Web;
using System.Web.Services;

namespace Director
{
 public class Hello : System.Web.Services.WebService
 {
  public Hello()
  {   InitializeComponent();  }

  #region Component Designer generated code
  
  private IContainer components = null;    
  private void InitializeComponent() {  }

  protected override void Dispose( bool disposing )  {
   if(disposing && components != null)
   {
    components.Dispose();
   }
   base.Dispose(disposing);  
  }
  #endregion

  [WebMethod]
  public string HelloWorld(string variable)  {
   return "Hello " + variable;
  }
 }
}

Flex Application:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
  <mx:WebService id="myService"
  wsdl="http://localhost/Director/Hello.asmx?WSDL"
  load="myService.HelloWorld('Peter')"
  showBusyCursor="true"/>
 
 <mx:Label text="{myService.HelloWorld.lastResult}"/>
</mx:Application>

If you're accessing a webservice on another machine or domain, don't forget the crossdomain.xml file in the IIS root:

<?xml version="1.0"?>
<!-- http://www.foo.com/crossdomain.xml -->
<cross-domain-policy>
    <allow-access-from domain="*"/>
</cross-domain-policy>
