Confucius

quote from Confucius' book Genuine Living says, "Developing in accordance with one's own nature is called "the way of self-realization." Proper pursuit of the way of self-realization is called "maturation"." In this quote, I believe Confucius proposes education for a but subject matter and form for that education would vary according to one's own nature. C.T.M.A.T.M. 78 At Confucius' own school, he would not teach "duflards", and would "only teach those who were bursting with eagerness for enlightenment." However he would not turn someone away because they had no money.

Pressing enter in textbox asp.net

<INPUT type="text" style="VISIBILITY: hidden;POSITION: absolute">


Start debugging again. You cannot see the second textbox, and everything looks like before. Try again to write something in first textbox. If you press enter now, form will submit, and your code for button's click event will now be executed. This is extremely different behavior, and you did nothing except you placed one invisible textbox on web form. :)
