Displaying PDF and Word Document

Hi,

I have used the methods to display HTML :

1. Link to Action and the IFrame -> The Result was the html file I was able to display in the same window.

2. Link to URL -> The Result was html file opened in different window.

3.IFrame and attaching the file in project -> it was resulted in html file getting dispalyed in IFrame.

Now if I want to extend the functionality for PDF or word document, is the procedure same or different

Can anyone enlighten me on this

Any thoughts on this.

Thanks in Advance
