Those sentences are unnatural. You could say "Thank you for reading my question", and "Have a nice day". However, please do not preface your questions with such introductions in future. Just go ahead and ask your question.

Note the correction. The sentence that you wrote was without tense.

I note that this is the third thread you've opened about this question. Please don't open new threads about one question. You are more than welcome to continue the discussion in the original thread if you so wish. I am going to close your second and third threads and keep the original open. I also note that the answer you received from emsr2d2 is accurate and fully addresses the question. If you were not satisfied with that, post below in that thread.
