Deployment Problems

Hi I'm kinda new to visual basic so please be patient. I have created a simple program in vb 2010 which has a button that opens a simple PDF file. This works well on my computer but when I download it to another computer, the program runs fine but it can't find the PDF file. I sort of presumed that when I build the application it would put the required files all together.

Can someone please advise me how to solve this problem, can I put the pdf in my resources file or something so it knows where it is or can I just put all the files including the pdf into a zip file so it is there when it is extracted.

Please can someone help! thanks
