westor: I don't think you should be blaming people for giving you example code that doesn't do exactly what you need. It's not "wrong", it's just incomplete. Instead of complaining, fix it yourself.
I didn't say that into that way, just said that is wrong! one if it is wrong then is not a code is a wrong!
, and i appreciate the example and his/her work for giving me the example and just i said the result's and nothing bad for him/her and for the code completeness
, i don't want to think that i am this kind of person! and nobody could be perfect all the humans guy's made and will make wrongs until the death :P
