[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!
