   Hi,

   what kind of dataType is returned from the loaderInfo.url? Must be a String…isn’t it?

   Charly,

   Yep, its a String. If I would have displayed the full URL, it would have shown:
   http://blog.flexexamples.com/wp-content/uploads/Application_loaderInfo_url_test/bin/main.swf

   Although I used the URLUtil.getServerName() method to just return the server name, or just “blog.flexexamples.com”.

   Couldn’t you also just use Application.application.url ?

   Dasa,

   Yes, I believe you can use Application.application.url if you just have one main SWF (Application.application.url and Application.application.loaderInfo.url should return the same value), but if you’re loading another Flex SWF using the SWFLoader control, I believe they start returning different values.

   For example, in the loaded SWF, I believe Application.application.loaderInfo.url returns the current losded SWF file’s URL, whereas Application.application.url returns the parent SWFs URL.

   At least thats what I think.

   Thanks for this one peterd – I’d been scouring around all morning trying to find a solution like this!

   peterd,
   Very handy. Does URLUtil has functions to get referer and user agent, similar to PHP’s $_SERVER['HTTP_REFERER'] and $_SERVER['HTTP_USER_AGENT']? Thank you.

   Wayne,

   I don’t believe it does, but you could use the ExternalInterface API to get that information from your HTML container using JavaScript. For example, see “Returning values from JavaScript in your Flex applications using the ExternalInterface API”.

    I found a work around for this problem:

    use a full url in request.url as follows

    var serverName : String URLUtil.getServerName(Application.application.loaderInfo.url;
    var request:URLRequest = new URLRequest();
    request.url = "https://" + serverName + ":8443/appContext/uploadServlet";
    fileReference.upload(request);

    Hi
    I have a project where i have a flex application that launches a.swf file and need’s to add a uri value to the .swf, and i am not sure how to begin with this.

    The .swf file currently has a datainput field where you can manually type the uri value, but i need the flex input value to automatically overwrite or be added to this component….

    This is pulling my hair out, any help would be much appreciated. I would even compensate someone for helping me here as i have a deadline approaching.

    Regards

    steve

      Steve,

      I’m a little unclear on what you’re trying to do. Are you trying to load an external SWF into a Flex project at runtime (presumably using SWFLoader) and pass variables to the nested SWF?

      If so, does this help:

      <?xml version="1.0" encoding="utf-8"?>
      <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
       
          <mx:Script>
              <![CDATA[
                  protected function btn_clickHandler(evt:MouseEvent):void {
                      swfLdr.source = "subApp.swf?text=" + encodeURIComponent(txtInput.text) + "&color=" + cp.selectedColor;
                  }
              ]]>
          </mx:Script>
       
          <mx:ApplicationControlBar dock="true" defaultButton="{btn}">
              <mx:TextInput id="txtInput" maxChars="32" />
              <mx:ColorPicker id="cp" />
              <mx:Button id="btn" label="Send and Load" click="btn_clickHandler(event);" />
          </mx:ApplicationControlBar>
       
          <mx:SWFLoader id="swfLdr" width="320" height="240" />
       
      </mx:Application>

      And my nested SWF, subApp.swf, was built from the following (subApp.mxml):

      <?xml version="1.0" encoding="utf-8"?>
      <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
              backgroundColor="haloBlue"
              applicationComplete="init();">
       
          <mx:Script>
              <![CDATA[
                  protected function init():void {
                      lbl.text = this.loaderInfo.parameters.text;
                      lbl.setStyle("color", this.loaderInfo.parameters.color);
                  }
              ]]>
          </mx:Script>
       
          <mx:Text id="lbl"
                  fontSize="32"
                  width="90%" height="90%"
                  horizontalCenter="0" verticalCenter="0" />
       
      </mx:Application>

      Or, for bonus points, here’s how you could create the loaded sub-application using ActionScript only (oooooh, fancy!):

      package {
          import flash.display.MovieClip;
          import flash.text.TextField;
          import flash.text.TextFormat;
       
          [SWF(width="320", height="240", backgroundColor="#CCCCCC")]
       
          public class subASApp extends MovieClip {
              public var tf:TextField;
       
              public function subASApp() {
                  super();
                  init();
              }
       
              private function init():void {
                  var fmt:TextFormat = new TextFormat();
                  fmt.font = "Arial";
                  fmt.size = 24;
                  if (this.loaderInfo.parameters.hasOwnProperty("color")) {
                      fmt.color = parseInt(this.loaderInfo.parameters.color);
                  }
       
                  tf = new TextField();
                  tf.width = 300;
                  tf.height = 220;
                  tf.x = 10;
                  tf.y = 10;
                  tf.wordWrap = true;
                  tf.multiline = true;
                  tf.defaultTextFormat = fmt;
                  tf.text = this.loaderInfo.parameters.text;
                  if (tf.text.length == 0) {
                      tf.text = "(default)";
                  }
                  addChild(tf);
              }
          }
      }

    Thanks for the posting. I have a flex application that communicates with a .net webservice. The problem is I do not want to hard code the webservice address. ie wsdl=”http://…..” How do I know the domain name at runtime where the application is hosted. Please help.
