i've been trying decide best way store information in vbo's opengl. i've been reading how matricies stored single-dimensional arrays because of performance penalties of using multi-dimensional arrays. i wondering, extend storing information in vbo's? make more sense store vertex information within vbos in single or multidimensional arrays? before bunch of answers saying depends on i'm storing, i'm talking things traditionally considered multidimensional arrays (maps, grids, etc....). what type of performance hits looking @ using multidimensional arrays if any? the question invalid, makes no sense. buffer objects blocks of memory stored , managed opengl. it's not c# array or c# multi-dimensional array. it's block of memory transfer data into. the vertex data put buffer object must conform glvertexattribpointer allows. how achieve in c# , whatever api use.

i can find getx(), , gety() both return float. how detect if coordinates of touchevent e.get(), e.gety() within boundaries of edittext ui element? notice getx() , gety() floats getheight(), , getwidth() int. not going comparisons ... what want do? if want detect if edittext touched, add ontouchlistener edittext... or onclicklistener. edit: if want detect outside, can detect touch event in containing view, , then, given have edittext view: rect edittextrect = new rect(); myedittext.gethitrect(edittextrect); if (!edittextrect.contains((int)event.getx(), (int)event.gety())) { log.d("test", "touch not inside myedittext"); } or add touch listener both edittext , container, , return false in 1 of edittext, way intercepted , not forwarded parent. so, touches detect in listener of parent, not belong edittext.

basically json output -output php. [{"attr":{"id":"node_2","rel":"default"},"data":"c:","state":"closed"},{"attr":{"id":"node_3","rel":"drive"},"data":"d:","state":"closed"}] so because rel equal default {"attr":{"id":"node_2","rel":"default"},"data":"c:","state":"closed"} i need remove array. i have thought of maybe using foreach($arr $key => &$item) { if ($value['rel'] == 'default'{ unset($arr[$key]); this however, wont work reason. have no idea if method best way, or whether there better way achieve this. need decode , encode it. you can use json_encode , json_decode parse json jesse bunch said. after decoded json posted, returned object. call on object have things bit diffrent. $a...

background: i'm developing application involves taking existing pdf form , overlaying text on top of it. pdf version 1.3. i'm using fpdfi class (written in php) can found here: http://www.setasign.de/support/manuals/fpdi/ i using fpdfi extension of tcpdf class found here: http://www.tcpdf.org/index.php i use line of (php) code looks this: $this->setxy(25, 250);$this->cell(0, 8.6, $data['my_data_to_overlay']); where $this refers instance of fpdfi class, setxy function tells coordinates wish place text (x,y), , cell function tells text want displayed , how large , such. page height 279.4 (all units here in mm) the problem: if set y coordinate higher 250 (even @ 251), text placed on next page instead of near bottom of current page expected. other coordinates above line @ 250 display properly, @ top edge of page. why can not overlay text near bottom of page? doing wrong? also of note: margins page set 0 , headers , footers disabled. disable auto page br...

do think smartphone characteristics able stand android os? - 100 mb storage - -64 mb ram - processor pnx-4910 ////edit--_ old version/ stable version?? android 2.1+ requires @ least 92mb of ram. see: http://static.googleusercontent.com/external_content/untrusted_dlcp/source.android.com/en/us/compatibility/2.1/android-2.1-cdd.pdf so hope pre 2.1 version. theoretically, might able 1.6 or earlier work on it, arm926 chip inside pnx-4910 not going withstand whole lot of load.

i create c++ project in xcode links against qt framework. hello world program works well. when add class derived qobject , add q_objcet macro, there link error. the class myobject.h #ifndef myobject_h #define myobject_h #include <qtcore/qobject> class myobject : public qobject { q_object public: myobject(); }; #endif myobject.cpp #include "myobject.h" myobject::myobject() { } i know should use moc compile myobject.h first , add generated moc_myobject.cpp xcode project. in microsoft visual studio, can configure header file compiled moc custom tool. , add generate cpp file vs project. but xcode. question is: there equivalent mean in xcode compile header file including q_object macro? here's how in xcode 6: select target , in build rules make new custom rule. set "process" drop down "source files names matching" , type in *.h next that. set "using" drop down "custom script:" , in script type close this: /path/to/...

so i'm having bit of frustrating day. fired contract had been working past few weeks because did not "mesh team." 2 examples cited: 1) yesterday asked delete data sql server database except baseline system data. requestor (not boss) had 8 scripts had used task few months ago. apparently no 1 has ever thought script out data model or system data. this person had established pattern of over-complicating things, trying understand reasons task , end goal. struggled understand why got sorts of vague errors required these scripts "remove , re-add constraints". i quite willing necessary , talked several minutes it. obvious reasons thought seeking understand why thing. decided faster herself rather spend time explaining me , went other work without thinking more it. somehow interpreted negatively. 2) several weeks ago during first week asked work on merging data system. given 600+ line script of sql snippets appeared important along oral tirade of complaints poo...

i find myself needing keep 2 lists of objects performance reasons (speed on memory). i'm using object pointers such as std::list<myclass*> m_list1; std::list<myclass*> m_list2; i add objects list by myclass* myobject = new myclass(); m_list1.push_back(myobject); m_list2.push_back(myobject); the problem i'm facing changes make m_list1 not affecting m_list2 , copies , not real deal. what correct way store these won't copies? not using pointers isn't option these allocated on heap. std containers copy values passed in, since passed in pointers, pointers copied. therefore still pointing same object. problem must somewhere else. perhaps post specific code think exhibiting behavior?
