Re: How can I change the content of a text layer??

Hi Dmitry:

Again thanks for your help.

I tried what you suggested but I have the problem that a void swf file is
created. I have followed the code and I have found that the method process
of the FlashObject class is void and is executed, so I supose that this is
the reason why I obtain an empty file.

Do I have a wrong version of the library? Is not this the reason of the
failing?

Thanks in advance for your help

Leónidas,

I would recommend you to look at com.iv.flash.Generator class. In short you
need something
like this:

             try {
                 file = FlashFile.parse(inFileName, false, encoding);
             } catch( FileNotFoundException e ) {
                 Log.logRB(Resource.FILENOTFOUND, new Object[] {inFileName},
e);
             }

             if( file != null ) {
                 // load environment
                 Context context = new StandardContext();

                 context.setValue("make", "BMW");
                 context.setValue("model", "328i");

                 file.processFile(context);

                 try {
                     file.setCompressed(compressOutput);
                     FlashOutput fob = file.generate();
                     BufferedOutputStream bos = new BufferedOutputStream(
new FileOutputStream( outFileName ) );
                     bos.write( fob.getBuf(), 0, fob.getSize() );
                     bos.close();
                 } catch( IOException e ) {
                     Log.logRB(Resource.ERRWRITINGFILE, new Object[]
{outFileName}, e);
                 }

             }

so now if in this file there is a text like: "My car is {make} {model}",
then
after file.processFile(context) it will be: "My car is BMW 328i"

I hope it helps!
