displayin document in Smartform

Hi everyone.

I am using the following code to read an attachment .

At the end of this code i'm using GUI_DOWNLOAD to download the data read from attachment into my system as a word document say filename C:\ XYZ.doc .This is working fine giving the right output

But My requirement is to display that document in the main window of smartform output.

what should i do after reading to display the attachment in smartform ? Is it required to Use GUI_DOWNLOAD and then read again and display in smartform?
