Help me set-up my desktop to an HDTV (with different ports)

Hey guys last night a friend gave me his old 32 inch HDTV (Samsung)...

I want to use it as my computer monitor but all it has on the back is a VGA port... My desktop has (2) DVI-D ports

I want to be using DVI-D though, as I think is looks alot clearer/sharper then VGA...

What will I need to connect my computer (DVI-D) to this 32 inch TV which has a VGA input on it...

Thanks guys!!!!
