javascript - Scrolling to milestones on page -


im working on website contains of 1 page has 6 divs beneath each other. each div's size screen filling. got script scrolls top of each div, depending on link clicked in navi.

the problem got want write script makes possible autoscroll previous/next div if scroll up/down. example: im on landing screen, seeing first div. if scroll down now, want page autoscroll second (next) div. after animation done , scroll further, script should autoscroll third div , on.

here code far

var position0 = 0; var idarray = ["landingpage", "news", "show", "media", "blog", "contact"]; // divs' ids var milestones = new array();  window.onload = function getpositions() {     position0 = $(window).scrolltop();     //getting current position of window     (var = 0; < idarray.length; i++) {         var genid = idarray[i];         var getheight = document.getelementbyid(genid).offsettop;         milestones.push(getheight)         //filling milestones array positions needed     }; };   window.onscroll = scroll;  var direction = ""; //calculated in function below  function scroll() {     var position1 = $(window).scrolltop();     // getting new position of window     var direction = position1 - position0;     // calculating direction seperate , down scrolling      // following part wrong 1      (var = 0; < milestones.length; i++) {         var x = milestones[i];         if (direction > 0 && x > position1) {             direction = 0;             $('html,body').animate({                 scrolltop: x             }, 750);             return false;             break;         };     }; };

im aware there jquery mixed within javascript comands work fine.

if execute code, works once cant scroll few seconds, because .onscroll event triggers more once. further not sure if animated scrolling triggers scroll event :/

feel free change code as want

i hope can me

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
