As a general hint, if people often have to ask you for clarification, that is a general hint not that the people are stupid but that your questions are unclear.
More concrete, as you come here for help, it makes easier for all potential answerers if you work as much as possible on making your question as clear as possible, for example by showing concrete examples and by presenting working code and also by telling how the parts should interact.
"I don't know why you or others can't comprehend."
So the common denominator in all this is you. Either everyone else reading your posts has a problem, or you have a problem asking for help, reading documentation, learning how to use the technologies you've chose. One only has to look at your post history (here and on other sites you cross post on) to figure out which of these two scenarios is true. Part of the problem could be that English isn't your first language. Also if you are using this thread as an example, then anonymous monk asked a question in response to yours before providing any advice.
As previously explained many times over the years, the better you explain your problems, the easier they are for others to understand and advise on. If people ask for clarification (as with most of your posts) then you're doing something wrong. See I know what I mean. Why don't you? though I doubt you'll bother reading it or taking posting advice. Why change the habit now after so many years?
