Convert binary file to pdf and show on webpage. How to?

Question

Hi everybody!
I hope that someone cna help me with this...
This is my situation:
I have a pdf file saved in my sql server 2005 db. It has been saved in binary format. I need to bring this pdf file out to my aspx page and then make adobe reader open the pdf file.
How do I convert the pdf file from binary to a file that I can open?
How do I from the webpage open adobe reader and make it read my pdf file?

I have tried some different things but keep getting errors like "An error occured with Adobe Reader. Please restart the application" then adobe reader opens and gives me this message "File not found..."

Any idea whats wrong?
