Welcome to Stack Overflow. Please take the tour to learn how Stack Overflow works and read How to Ask on how to improve the quality of your question. Then check the help center to see what questions you can ask. Please see: Why is “Is it possible to…” a poorly worded question? (don't just change your question to "How"). You might want to delete this question and ask it on cs.stackexchange.com instead, but check the help pages there first. — Progman 39 secs ago
