Wed, 18 Jun 2008 11:44:30 +0000 http://wordpress.org/?v=2.5.1 en Select and access local SWF files within an AIR application http://blog.derraab.com/2008/06/17/select-and-access-local-swf-files-within-an-air-application/ http://blog.derraab.com/2008/06/17/select-and-access-local-swf-files-within-an-air-application/#comments Tue, 17 Jun 2008 15:44:32 +0000 derRaab http://blog.derraab.com/?p=36 Well, it took me a little time to figure out how to select and load a local SWF file into an SWFLoader instance. Several times I got this error message:

“SecurityError: Error #3015: Loader.loadBytes() is not permitted to load content with executable code.”

After some research I found this "dreaming in flash" blog entry which basically contains the solution I was looking for.

But then it took me a little more time to figure out how to use this with the SWFLoader. So here is a basic code example:

PLAIN TEXT
Actionscript:
  1. import flash.display.Loader;
  2. import flash.filesystem.File;
  3. import flash.filesystem.FileMode;
  4. import flash.filesystem.FileStream;
  5. import flash.system.LoaderContext;
  6. import flash.utils.ByteArray;
  7. import mx.controls.SWFLoader;
  8.  
  9. // File reference
  10. var swfFile: File;
  11.  
  12. // Open the SWF file
  13. var fileStream: FileStream = new FileStream();
  14.     fileStream.open( swfFile, FileMode.READ );
  15.  
  16. // Read SWF bytes into byte array and close file
  17. var swfBytes: ByteArray = new ByteArray();
  18.     fileStream.readBytes( swfBytes );
  19.     fileStream.close();
  20.  
  21. // Prepare the loader context to avoid security error
  22. var loaderContext: LoaderContext = new LoaderContext();
  23.     loaderContext.allowLoadBytesCodeExecution = true; // that's it!
  24.    
  25. // Now you could use this with a Loader instance
  26. var loader: Loader = new Loader();
  27.     loader.loadBytes( swfBytes, loaderContext );
  28.    
  29. // Or you could use this with a SWFLoader instance
  30. var swfLoader: SWFLoader = new SWFLoader();
  31.     swfLoader.loaderContext = loaderContext;
  32.     swfLoader.source = swfBytes;

They give a quick introduction in AS 3 and it's core benefits!

Also a must read for developers!

I tried serveral ways to declare the href tag, but only the last one works...

PLAIN TEXT
HTML:
  1. <link href="../style.css" rel="stylesheet" type="text/css" />
  2. <link href="./../style.css" rel="stylesheet" type="text/css" />
  3. <link href="..\style.css" rel="stylesheet" type="text/css" />
  4. <link href="style.css" rel="stylesheet" type="text/css" />

Maybe there is a solution? I can't figure it out.

But the Flash Player doesn't provide enhanced audio support, actually it seems to get worse.

So we all should support the Adobe, MAKE SOME NOISE campain!

This seems to be a security feature and makes sense, because some systems would not allow to write into this directory at system level.

But for testing purposes you might hack this by using a single line of code:

PLAIN TEXT
Actionscript:
  1. // Writing into that file would fail
  2. var yourFileInAppDir: File = File.applicationDirectory.resolvePath( "yourFile.xml" );
  3. // This is the simple hack:
  4. yourFileInAppDir = new File( yourFileInAppDir.nativePath );

But this only avoids a AIR security error! You must be sure to have write access to the directory!
