The latter may be more difficult, but the first question could be easily remedied with a quick google search I guess.

Thanks for the reply, iamthwee, but I'm only asking on here because I've yet to find a googled search result that has yielded anything useful to me (and in a more grammatical, less syntatic way).

I can understand that 95% of people asking for help on these sorts of things would just ask them without trying to look them up, but I'm of the 5% that look first, then ask if need be.
