currently,i'm having double trouble. unable crop bitmap. unable save multiple bitmaps. recently, i've made camera app saves jpeg image sd card without frail, however, wanted crop bitmap , save 2 parts (save 2 images same folder). however, i'm unable crop bitmaps in current code. and second problem tested , tried save same bitmaps testing purpose same folder using fileoutputstreams failed.(actually want save cropped version of bitmap). everything seemed well, until now. since i'm noob may missing or may have done nonsense codes. i've put codes (method) tried , failed. public static void makerotateimage(activity activity, byte[] data, int maxpixel) { // original bitmap bitmap bitmapsrc = maketargetpixelimage(data, maxpixel); // degrees int degree = getcameradisplayorientation(activity); int destwidth = 0; int destheight = 0; //alter or rotate if (degree % 180 == 0) { d...

i have troubles in grouping datasets. here query , query result. select count(*),salarie_id, created_at enregistrement group salarie_id, created_at my point group similar created_at rows, in interval of +/- 3 sec. didn't manage it, in using interval , in such criterias having , where ... between . how can group these rows get, example 36 (33+3) in count result, shown in image ? didn't found suitable solution... let me know if want additional information. update 1 : looks @fancypants solution on right way. select count(*),salarie_id, date_format(created_at, concat('%y-%m-%d %h:%i:', left(right(created_at, 2), 1), right(created_at, 1) % 3)) 'date' enregistrement group salarie_id, date_format(created_at, concat('%y-%m-%d %h:%i:', left(right(created_at, 2), 1), right(created_at, 1) % 3)) select count(*),salarie_id, created_at enregistrement group salarie_id, date_format(created_at, concat('%y-%m-%d %h:%i:', left(ri...

my question pretty simple, can't detect element, wanna change backgroundcolor through javascript can't check since tag+class + tag+class... here's code tried: var 1 = document.getelementsbytagname("div"); var 2 = document.getelementsbyclassname("red"); var 3 = document.getelementsbytagname("h2"); var 4 = document.getelementsbyclassname("title"); one.two three.four.style.backgroundcolor ="#00c497"; the format "div.red h2.title". hope me, thanks if can, use queryselector this: document.queryselector("div.red h2.title").style.backgroundcolor = "#00c497"; <div> <h2>don't touch</h2> </div> <div class="red"> <h2>don't touch</h2> <h2 class="title">change</h2> </div>

i have spreadsheet submitted 3rd party apps (which can't change code). then, need send http (post) automatically http://thisismyurl.url/go.aspx?fieldone=xxx&fieldtwo=xxx when google spreadsheet updated. what in mind create script in google spreadsheet , use urlfetchapp in code. function sendhttppost() { //how pick data field in last column (everytime google spreadsheet updated)? var data = { "fieldone" : "value field 1 (from last column)", "fieldtwo" : "value field 2 (from last column)", }; var options = { "method" : "post", "payload" : data }; urlfetchapp.fetch("http://thisismyurl.url/go.aspx", options); } i know missed command fetch data spreadsheet. idea this? thanks helping me :) thanks @mogsdad giving clue me. , @zig mandel suggesting me read spreadsheetapp documentation. here did in code, , it's works! // spreadsheet object v...

i have read 1 can call std::set_terminate() use own function global exception handler, catches unhandled exceptions. simplified code of program: #include <exception> #include <stdexcept> #include <iostream> void my_terminate_handler() { std::cerr << "terminate handler" << std::endl; std::cin.get(); std::abort(); } int main() { std::set_terminate(my_terminate_handler); int = 1; i--; std::cout << 1/i << std::endl; return 0; } why my_terminate_handler() never invoked? both in vc++ 2013, 2015 rc , gcc++-4.8. the terminate handler called if program calls terminate . can happen various reasons - including uncaught exception - division 0 isn't 1 of reasons. gives undefined behaviour; typically, raises signal (not c++ exception), , you'd need install signal handler, not terminate handler, catch that.

there lot of explanation big-0, i'm confused on part. acoording definition of big-o in function f (n) ≤ c ·g(n), n ≥ n0 “ f (n) big-oh of g(n).” but description of function in terms of big o notation provides upper bound on growth rate of function. so e.g here 34 upper bound set { 5, 10, 34 } so if in graph how f(n) o(g(n)) because if upper bound of g(n) function it's value different mentioned here n>=n0 .. beyond n0, f(n) not grow faster g(n). f(n)'s rate of growth function of n @ g(n). g(n)'s rate of growth said upper-bound of f(n)'s rate of growth of f(n) big-o of g(n). the worst case rate of growth of f(n) @ g(n) since f(n) big-o of g(n). this knowing how big f(n) can grow relative known function. for example, if f(n) = n^2, , g(n) n^3, trivially f(n) big-o of g(n) since n^2 never grow faster n^3. "c" used mathematical proofs - it's linear scaling variable. can't go around , claim big-o of else. if choose...
