Reading the application descriptor file

You can read the application descriptor file of the currently running application, as an XML object, by getting the applicationDescriptor property of the NativeApplication object, as in the following:

var appXml:XML = NativeApplication.nativeApplication.applicationDescriptor;

You can then access the application descriptor data as an XML (E4X) object, as in the following:

var appXml:XML = NativeApplication.nativeApplication.applicationDescriptor;
var ns:Namespace = appXml.namespace();
var appId = appXml.ns::id[0];
var appVersion = appXml.ns::version[0];
var appName = appXml.ns::filename[0];
air.trace("appId:", appId);
air.trace("version:", appVersion);
air.trace("filename:", appName);

For more information, see The application descriptor file structure.

var fileTypes:XML = appXml.ns::fileTypes[0];

                    for each ( var fileType:XML in fileTypes.ns::fileType ) {

                        trace(fileType.ns::name);

                    }

效果如下

            this.width = 16;
            this.height = 16;
            this.setStyle(“cornerRadius”,8);
            this.setStyle(“icon”,icon);
            this.setStyle(“downIcon”,downIcon);
            this.setStyle(“overIcon”,overIcon);
            this.setStyle(“upIcon”,icon);
        }
    }
}

这是一个应用程序启动前的窗口，可以用在多个方面，比如下载资源、检查更新、初始化控件等等

主程序调用：

this.visible = false;//set app invisible.
splashScreen = new Splash_Window();
splashScreen.addEventListener(Event.COMPLETE,function():void
{
       //闪过之后的处理，splashScreen
});
splashScreen.open();//show splash screen.

先写个wcf的svc服务
有个方法叫TestImage，返回一个图片的二进制数据
写好服务能用之后开始ActionScript的实现

先在build path里加入fiber.swc
我的fiber.swc路径是C:Program FilesAdobeAdobe Flash Builder 4pluginscom.adobe.flexbuilder.dcrad_4.0.0.272416dcradSwcs4.0libsfiber.swc

然后是代码

package WebService

{
import com.adobe.fiber.core.model_internal;
import com.adobe.fiber.services.wrapper.WebServiceWrapper;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.filesystem.File;
import flash.filesystem.FileMode;
import flash.filesystem.FileStream;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.net.URLRequestMethod;
import flash.net.URLVariables;
import flash.utils.ByteArray;
import mx.rpc.AbstractOperation;
import mx.rpc.AsyncToken;
import mx.rpc.events.ResultEvent;
import mx.rpc.soap.mxml.WebService;
public class ImageTest extends WebServiceWrapper
{
  public function ImageTest()
  {
    _serviceControl = new WebService();
    //load wsdl
    _serviceControl.loadWSDL("http://192.168.0.2:8080/EpubService/Service1.svc?wsdl");
    model_internal::initialize();
    getImage();
  }
  public function getImage():void
  {
    var operation:AbstractOperation = _serviceControl.getOperation("TestImage");
    operation.addEventListener(ResultEvent.RESULT,onresult);
    operation.send();
  }
  private function onresult(e:ResultEvent):void
  {
    var imgByte:ByteArray = e.result as ByteArray;
    var f:File = File.documentsDirectory.resolvePath("test.jpg");
    var fs:FileStream = new FileStream();
    try
    {
      //open file in write mode
      fs.open(f,FileMode.WRITE);
      //write bytes from the byte array
      fs.writeBytes(imgByte);
      trace("create file: "+f.nativePath);
    }
    catch(e:Error)
    {
      trace(e.message);
    }
    finally
    {
      //close the file
      fs.close();
    }
    }
  }
}

输出：

create file: C:UsersQingDocumentstest.jpg

html.htmlLoader.placeLoadStringContentInApplicationSandbox = true;
