[Swftools-common] Text search in SWF

[Pratyus Patnaik]

 I trying to build a simple application in flex in which I render a swf in
the application. I want to enable user to search text using a textbox
(id="SearchInpt") and button (id="SearchBtn").

I used this following command to convert the pdf to swf
 pdf2swf -f file.pdf -o file.swf   (thanks Matthias)

I am able to load the swf file into the application, but search always
fails. Below is the code I am using (source:
http://wiki.swftools.org/index.php/How_do_I_highlight_text_in_the_SWF%3F).

Am I missing something in the code. I will be grateful for any help or
pointers to resources.

Thanks!
