[dba-VB] Open PDF file

I am using VS 2005 and VB.Net for a web site.

I have a number of PDF files that are stored in a static folder on the server.

Users select from a list on files on a web page and I want to open 
the files in Adobe.  Adobe reader is installed on the server.

Can anyone give me a pointer to how I can take a string with path and 
file name, and open it?
