Your post is very unclear - could you try re-phrasing, and/or simplifying? What is your use case / what are your step-by-step expectations / what issue(s) are you experiencing with each of those steps when you try?
Do you think it is a good idea to start just another thread about the same issue we already talk about in at least two other threads?
It's ok,I already give up on it
it was not about that you should give up. Its about that we shouldn't have the same discussion three times of the same author. :) we can support you well, if there is "only" one thread.
then please tell me why there always null value for the data input?
