The most important thing to do is show your research! If you need help, you need to show people what you've done yourself to solve the problem and why your solutions didn't work. This shows that you're competent in the subject matter and will therefore get answers that are relevant. Otherwise, we're just guessing at an answer off vague information.
On your last question, it was closed because you didn't disclose any research or show any effort to find the answers yourself.
Further, reading the FAQ will help improve your questions so you'll get the answers you need without being downvoted/closed.
