What do people think about posters who ask "how do I do xyz in a BATCH file?", and you tell them, (i.e. summarize the steps) and they go "Uh?" and make it clear they REALLY meant, "Please write me a batch file that does xyz?". I have a problem with doing people's homework or paid work for them. Am I being unecessarily unhelpful?
Actually i'd say the opposite...you've been more than patient with most of them in the past.
Maybe just posting links to decent reference sources when you feel they are not putting any EFFORT in and wishing them luck with it is the best approach.No, it's one thing if someone's truly stuck -- even if it is homework -- and you can tell they're making an effort, or trying to work out the problem (and I've seen you help these folks), but it's quite another to just ask for the code without any effort (or at least a reasonable EXPLANATION of why it should be provided gratis.

(Not SAYING you should give services away, just saying these folks, some of them, don't even know how to properly ask / beg to make one even consider just giving away something.)
