i surprised today jpeg backed cgimage backed calayer (i mean [[jpeg backed cgimage] backed calayer] ) slow 8mp photo felt no gpu there. i tried creating new bitmap backed cgimage drawing original cgimage cgbitmapcontext, solved speed problem somehow. brought 6xmb memory burst (from 3mb) , took 1s or drawing thing. is there way decoded image original cgimage? or other ways make jpeg backed cgimage faster, maybe tell use cache bitmap , never trash it? i switched cgdataprovidercopydata approach. little faster, still takes 0.8s on iphone 4s. start wonder what's mechanism behind calayer backed encoded source? gets slow when image shrunk , more part of image got shown. not slow 1fps when whole picture shown (actually can still 10fps).

please help, cant seem do-while loop loop when ask user input continue using scanf , printf. wipe_buffer? can't seem right on , need finish loop , should functional. new coding , website please not harsh. please , thanks. #include <stdio.h> #include <stdlib.h> void wipe_buffer(void); int main(int argc, char* argv[]) { char play1; char play2; char cont; do{ printf("player 1 pick rock, paper, or scissors\n"); scanf(" %c", &play1); wipe_buffer(); printf("player 2 pick rock, paper, or scissors\n"); scanf(" %c", &play2); wipe_buffer(); switch(play1) { case 'r': if(play2 == 'p' || play2 == 'p') { printf("paper covers rock\n"); printf("player 2 wins\n"); } if(play2 == 's' || play2 == ...

hi have code looks this: var myclass = { globalvar : { total : 100 }, myfunction : { gettotal : function() { return this.globalvar.total; } }, }; // uncaught typeerror: cannot read property 'total' of undefined alert(myclass.myfunction.gettotal() ); the keyword this returns undefined , why that? because use var myclass instead of function myclass() ? thanks [edit] here's jsfiddle http://jsfiddle.net/darcfiddle/cg7fk/ this turns out myfunction it's you're saying myfunction.globalvar.total doesn't exist. you could make re-usable if wanted. function food(cost) { this.gettotal = function () { return cost + (cost * 0.05); // add 5% }; } var sandwich = new food(2.50); alert( sandwich.gettotal() ); // 2.625 http://jsfiddle.net/thetenfold/hvhxr/ there many ways make "class" (so speak) . not way, it's decent way.

i have edittext in app user can enter decimal volume in. at moment use: edittext edittextvolume = (edittext)findviewbyid(r.id.edit_vol); edittextvolume.setinputtype(inputtype.type_class_number|inputtype.type_number_flag_decimal); to numerical keypad. there anyway can have same keypad button * or x can allow user input example 4x200 . i want 1 multiplication character (so no divide or other mathematical operators) is possible? not possible without implementing own custom keypad. however, if project requirements not strict, may use inputtype.type_class_phone . allow putting * symbol, make available several other symbols (e.g., # , + , . , , ) used in phone numbers.

i have eventlistener listens entire document , records keystrokes, want remove listener when conditions met. the following snippet of code: document.addeventlistener('keyup', function(e) { var letter_entered = string.fromcharcode(e.keycode).tolowercase(); player.makeguess(letter_entered); if(player.win_status === true || player.lose_status === true) { document.removeeventlistener('keyup', arguments.callee, false); } }); this works, according mozilla developer docs method has been deprecated. i'm aware can name function, is there alternative allow me continue using unnamed function ? use following process: create variable assign anonymous function variable invoke variable reference the anonymous function references using variable name use such: var foo = function(e) { "use strict"; console.log(e); document.removeeventlistener('keyup', foo, false); } document.addeventl...
