My earlier post on how to write a good question is pretty long, and I suspect that even when I refer people to it, often they don’t bother reading it. So here’s a short list of questions to check after you’ve written a question (and to think about before you write the question):
If the answer to any of these questions is "no" you should take the time to fix up your question before posting. I realize this may seem like a lot of effort, but it will help you to get a useful answer as quickly as possible. Don’t forget that you’re basically asking other people to help you out of the goodness of their heart – it’s up to you to do all you can to make that as simple as possible.
1 If you went from "something’s not working" to "asking a question" in less than 10 minutes, you probably haven’t done enough research.
2 Ideally anyone answering the question should be able to copy your code, paste it into a text editor, compile it, run it, and observe the problem. Console applications are good for this – unless your question is directly about a user interface aspect, prefer to write a short console app. Remove anything not directly related to your question, but keep it complete enough to run.
3 Try to avoid code which makes users scroll horizontally. You may well need to change how you split lines from how you have it in your IDE. Take the time to make it as clear as possible for those trying to help you.
4 I realize that English isn’t the first language for many Stack Overflow users. We’re not looking for perfection – just some effort. If you know your English isn’t good, see if a colleague or friend can help you with your question before you post it.
