i want scroll top after post back. in login page when click on login button , if there validation error message scrolls bottom. not bottom scroll down first text field. want stop default scrolling , want scroll top. using following code:

<script type="text/javascript">      jquery(document).ready(function () {      jquery("#scrolltop").val(0);      var prm = sys.webforms.pagerequestmanager.getinstance();      prm.add_endrequest(function (s, e) {          jquery("#scrolltop").val(0);          window.scrollto(0, 0);          $('html, body').animate({ scrolltop: 0 }, 'fast');         // alert('postback end!');      });      prm.add_beginrequest(function (s, e) {          jquery("#scrolltop").val(0);          window.scrollto(0, 0);          $('html, body').animate({ scrolltop: 0 }, 'fast');      });  });

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
