pointers,deallocation and vector in c++ -

-

i want know should explicitly deallocate pointers erase vector myvector.erase(); .

for example;

class sample1{    public:          removesample2(sample2 * a)          {              if(// if find in samplelist1 vector index ){                    // should call here delete or pointer ?                    samplelist1.erase(samplelist1.begin()+i);               }          }     private:       vector<int *> samplelist1;              }   class sample2{      public:            // not important areas      private:           sample1 * example;              }

there's no way possibly know, since don't know you're trying do. basic answer is:

  1. if collection logically owns things in it, doing wrong. never use ordinary collections of ordinary pointers purpose. things go horribly wrong if you, example, copy collection. (either use ordinary collections of smart pointers or collections designed hold pointers , manage lifetimes of objects in them.)

  2. if collection not own things in it, not delete pointers collection. cause other code uses pointers access object after has been deleted.

if set mycoolbar.fixedorder true,only grip on first band hidden. well,if use delphi 7 create vcl forms application,then put coolbar on , create 3 coolbans hold other controls,only grip , top coolbands can hidden setting mycoolbar.fixedorder:=true. i've uploaded picture make things clear. you got fixedorder property wrong. fixed property not allow bands rearranged if set true . setting property of coolbar true keep user changing bands order @ runtime, user can still move , resize bands. can give advice can do, actual solution problem, well, have wait answer. my advice use 3 coolbars in row , setting "fixedorder" property true , bandborderstyle bsnone . way grip hidden on of them. about property, it's not bug of ide, actual preference of property.

javascript - Animating array of divs; only the final element is modified -

this baffling me @ moment. i'm experienced programmer looking throw bit of surprise fiancee on countdown page our wedding. desired effect simulated confetti falling behind main page. setup follows: i have array of divs in javascript. each div absolutely positioned on page. have interval set updates every 50 or milliseconds. on each tick, run loop on array of divs, , calculations , update positions. problem problem having, however, though can see divs created, stored array, , modified (in case, each has slight randomized rotation) during initialization phase, once tick update position starts, div stored in whatever last slot of array gets position updated. tried hard-coding each div index testing purposes, strictly last element update position. upon printing current "left" , "top" style values each div before , after calculations shows value has been changed, no visible change noticeable. here's basic code: javascript var container;
