Problem with consuming a .NET web service from Flex-ActionScript

[gabrielk43]

Hi I am new to Flex and I use Flex Builder 2 to make a web service client. So I have a web service in .NET(c#) with a simple web method that returns a string(no arguments). It works, I tested it using firefox. I have managed to consume the service in Flex by using MXML like this:

<mx:WebService id="wsTestWebService" wsdl="http://localhost:3521/AjaxControlToolkitWebSite2/TestFlexService.asmx?wsdl"showBusyCursor="true" load="wsTestWebService.getGameUsers()">
</mx:WebService>

and then in a text control I do this:

<mx:Text x="107.5" y="534" width="243" id="text1" height="22" text="{wsTestWebService.getGameUsers.lastResult}"/>

Now my first question is this: How can I access the string that the wsTestWebService returns by actionscript? It seems that if I try to write

text1.text = wsTestWebService.getGameUsers.lastResult;

in a .as source file, I get nothing.

The thing is that I want to do everything by using actionscript so I tried that:
I placed a button in my project and a click event handler for that. The code is this:

private var isLoaded:Boolean = false;
private var hasResult:Boolean = false;

private function OnClick():void
{
var ws:WebService = new WebService();
ws.wsdl = "http://localhost:3521/AjaxControlToolkitWebSite2/TestFlexService.asmx?wsdl";
ws.addEventListener(LoadEvent.LOAD, load_listener);
ws.addEventListener(ResultEvent.RESULT, result_listener);
ws.loadWSDL();
var strXML:String;
if(isLoaded)
{
ws.getGameUsers.send();
}

if(hasResult)
{
text1.text = ws.getGameUsers.lastResult;
}
}



private function load_listener(event:LoadEvent):void
{
isLoaded = true;
}


private function result_listener(event:ResultEvent):void
{
hasResult = true;
}



Nothing happens. So what's wrong with this anyway? I have problems in understanding how to use the WebService class in actionscript but that's the way I want to do it anyway, not by MXML. Thanks in advance.
