c++ - How to store the vector.begin() iterator of template type in thrust? -

-

when attempt assign variable iterator, error: expected ";", vec thrust::device_vector<my_type>, j int, , my_type template type:

for (thrust::device_vector<my_type>::iterator = vec.begin(); < vec.end(); += j) foo(i);

is correct way loop on vector? declaring i correct type?

standard containers use iterators traversing through collection of other objects (i.e. elements), since iterator abstract concept implemented in standard containers, can implement iterators in following way: 

typename thrust::device_vector<my_type>::iterator = vec.begin(); (it; != vec.end(); = it+j)     foo(*it);

here's reference stl containers: http://www.cplusplus.com/reference/stl/

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.

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;
