How is this related to MySQL? If you want to save an array in a row, you're breaking basic normalisation rules.

Finding a process by name is a rather lenghty operation (you must go through EnumWindows [^]).

Start here[^], it contains everything you need to get you started for development on Windows :) I are troll :)
