is right way match 2 divs? var div2 = document.getelementsbyclassname("div2"); div2.style.borderradius = "100px" document.getelementbyid("div1").style.borderradius = div2.style.borderradius; just newbie @ javascript. just comment on code, document.getelementsbyclassname() returns htmlcollection, not single dom element. should use document.getelementbyid() or document.queryselector() if you're trying 1 element. and don't want use js add styling, unless styling want use dynamic. case, should use css file , add class: .round-border { border-radius: 100px; } if still want use js add class instead of putting in html, can following: document.getelementbyid("div1").classlist.add('round-border'); document.getelementbyid("div2").classlist.add('round-border'); this assuming gave html elements correct id names. but said, because using static value of 100px , make more sense add class eleme...

in program i'm writing, user needs able select cell in grid , edit value. program shows value of selected value in hexadecimal (so (0,0) 0x00 , (1,3) 0x19 , etc.) had display updated through binding wx.grd.evt_grid_select_cell event. however, upon doing this, gridcursor no longer move, stay on (0,0). so, added setgridcursor statement handler have move cursor when handler called. however, generated infinite loop, apparently setgridcursor generates evt_grid_select_cell command when called. my question is, how have code executes when new cell selected while still maintaining old cell selection functionality? adding event.skip() @ end of custom handler passes event default handler.

this question has answer here: segmentation fault doesn't come after accessing out-of-bound memory 5 answers what's stored after end of character array? assuming there random garbage did not print after end while looping 10 times. char a[] = "pencil"; int i; (i = 0; < 10; i++) { printf("%c", a[i]); } so character array has size of 7. , loop looped until 10th position 3 more values looped through. did not print or error. what's going on here? accessing beyond end of array in c undefined behavior. program continue running unchanged or crash horrifically depending on stored past end of array. compiler makes no guarantees stored there - useless memory or critical program.

this question has answer here: scope of python variable in loop 7 answers i learning python , came across 'for loop' let's have program asks 5 numbers. know it's pointless it's example. anyway, if did this, wouldn't restart cycle. mynumbers = [] x in xrange(5): try: mynumbers.append( int(raw_input()) ) except valueerror: mynumbers = [] x = -1 i thought if had reset x -1 make loop go on more, never restarted. still only went 5 times. reason why put -1 there because x count 0 right after that. tried find solutions, there weren't any. thank if try me. xrange() (or range() ) called generator functions, x local variable loop assigns next value in loop to. xrange() returns values in range given in parameters 1 1 , , loop assigns variable x. if change value of x within loop, xrange() has no ide...

there many posts got use case of __init__.py , use define global variable 1 of them. want know there demerit in defining local variable in __init__.py ? there no technical reason prevents using __init__.py declaring global variables. nevertheless, mean of __init__.py modules define import structure of application. python documentation: the __init__.py files required make python treat directories containing packages; done prevent directories common name, such string, unintentionally hiding valid modules occur later on module search path. in simplest case, __init__.py can empty file, can execute initialization code package or set __all__ variable, described later. as developer, expect find in __init__.py file import layout of application itself. it's last place when i'm exploring source code. therefore, hiding implementation in __init__.py misleading. true global variable lifecycle definition hard follow. it's considered bad practice because brea...

i'm pretty new programming , java, i'm not sure. know jdk has own compiler , jre need eclipse? you need jre run java code on computer , jdk write it. however, many programmers tend prefer ide (integrated development environment) use along side writing code, debugging, , execute more efficiently. eclipse example of one, , 1 of many used/preferred ide's (in opinion @ least) out there. however, others exist too: drjava netbeans bluej jcreator these editors more preferred because make easier learn / write code. however, may choose normal text editor (like sublime, atom, textedit, notepad, textmate, etc..) or command line. mac & linux have "vim" built in command line editor tend prefer.

in fictional stylesheet several media query sections rules within relevant media query processed browser, example @media screen , (max-width: 400px) { .container { width: 95%; } } @media screen , (max-width: 800px) { .container { width: 80%; } } .container 95% wide on screen maximum width of 400px. my question this: though media query max 400px 1 relevant (in fictional example), media query max 800px cached browser, though irrelevant, or not? the browser might cache entire css file these media queries contained in, browsers not cache particular sections of css file. so answer question, yes browser might cache non-active part of media query since might (and will) cache entire css file.

i tried search question didn't find previous topic. hope didn't miss it. :) anyway; have program open image, applies couple of image enhancing algorithm , save results in folder. works normal images but, obviously, doesn't work hdr files. indeed, if select ".hdr" image , give run, behave didn't gave him image @ all. is there library allow me open , work (open , save) on kind of files? hdr images have high dynamic range. can't open , save in format (like can open jpg , save bmp). there regions bright, , others dark. so need sort of post processing (gamma correction , tone mapping) before storing standard dynamic range format. photoshop that. , there other commercial tools (search hdr processing). if you're looking free, imagemagic or blurate can extent, aren't advanced, , need tweaking.

this algorithmic problem bit complex me: i have numpy array of data internally indexed in peculiar way. data output of 2 arrays spliced (which don't have), distinct ordering. set parameter max positive integer, , data output has index format [ 00 10 20 ... max0 11 12 ... max1 22 23....max2 33....max max ] the parameter max determines output of array (i.e. length of array) , ordering. for several examples, max=2 , data of order [00 10 20 11 21 22] setting max=3 gives [00 10 20 30 11 21 31 22 32 33] and max=4 [00 10 20 30 40 11 21 31 41 22 32 42 33 43 44] and on. i write algorithm make list/array of 3x values, i.e. values first index 3. is, access certain data values, organized first index. however, determined parameter max . can see, determines datum placed array index. idea make sort of sorting tree, not sure how execute max parameter. this list comprehension (or iteration) produces indexs show [[j*10+i j in range(i,max+1)] in range(max...
