yestoday finished making waveform png images :) today tried make connection between image , soundmanager player.. no luck want add image background each song listed soundcloud cant .... just set fixed background image in css? put progressbar on top of opacity 0.2(?) or something, looks "progressing". assuming images in grey on soundcloud. if have 2 images, dont need opacity obviously. make sure both images same size, , start in same position. set background width: 100%, , progress image process/duration*100% unless actual question is, how current time, duration of song playing.

i've been trying jquery detect number of letters entered after each other on keyboard. actually, wanted achieve is, use .keypress function detect word instead of single character. now, can't type word , press keys @ same time, have program way jquery remembers letters i've typed in before, if write "test", remember "t,e , s" before type in last "t" make if condition come true. here's tried, don't know how store characters (basically keylogger, single word, used open application): $(document).keypress(function(e) { if( e.ctrlkey && ( e.which === 46 ) ) { alert('ctrl , del pressed!'); } }); this way, managed jquery recognize key combination, that's know now. can me figure out how detect whole world? thank much. based on comments: i think best way go grab text , check if contains item in whitelist. otherwise if user copy pastes, or moves input, miss characters. hesitate on keyup depe...

i try create junit test, probleme exception: caused by: java.lang.nullpointerexception @ com.liferay.portal.kernel.cache.key.cachekeygeneratorutil.getcachekeygenerator(cachekeygeneratorutil.java:56) the program can't instantiate the cachekeygenerator -cause defaultcachekeygenerator null!! latter can instantiated when portalcontextloaderlistener.contextinitialized(servletcontextevent servletcontextevent) called... i'm not using portalcontextloaderlistener ... there way solve probleme depending on you're test, advice typically additional level of indirection. if need depends on larger infrastructure initialized, in case, it's not proper unit test more, rather larger integration test. adding indirection cache-key should suffice. @ runtime can hook component liferay, @ testing time, return testing values, constants, random results or whatever need test.

each fontawesome icon set inherit font-size of parent. however, font best rendered @ specific sizes , if parent has different font-size: 14px; effect icon quality. question is, why use css this .fa {font-size: none;} .fa-lg {font-size: 1.33333333em;} .fa-2x {font-size: 2em;} .fa-3x {font-size: 3em;} .fa-4x {font-size: 4em;} .fa-5x {font-size: 5em;} without knowing what's parent font-size , therefore risk having badly rendered icons , not have this .fa {font-size: 14px;} .fa-lg {font-size: 19px;} .fa-2x {font-size: 28px;} .fa-3x {font-size: 42px;} .fa-4x {font-size: 56px;} .fa-5x {font-size: 70px;} where make sure each icon has best possible quality. so, know why font-awesome using 'em' units on 'px'. right? reason: lets have heading text ( <h1> ) of size 30px. , paragraph ( <p> ) text of 14px. both has icons. so, if font-awesome icons in fixed size 14px, render body text. small in heading tags, icon in 14px , heading text in 3...

i trying determine whether given string enumeration value or not. rather common string should decimal value. question whether takes longer enum.tryparse() on string or regex check decimal value or int32.tryparse() . if string not numeric (unsigned) decimal value, highly likely, not 100% guaranteed, string enum value. this check made many many times. want lowest average cost. you should profile code determine if problem. if not, whatever gives clear, concise (working) code. if problem, way pick approach use: bool probablyanumber = char.isdigit(mystr[0]); this should work because enums can't start digits, while numbers (with exceptions "-1" , " 1 " ). whether improvement or makes things worse depends on data set. it's worth noting enum s can parsed numbers, behavior of enum.tryparse may not expecting. enum myenum { zero, one, two, ten = 10 } myenum e; enum.tryparse<myenum>("10", out e); // succe...

i'd calculate length of replace string used in substitution. is, "bar" in :s/foo/bar . suppose have access command string, can run , undo it, , may separate parts marked / split(). how string length of replace string if contains special characters \1, \2 etc or ~? for instance if have :s/\v(foo)|(bars)/\2\rreplace/ the replace length strlen("bars\rreplace") = 12. edit: clear, hope use move cursor past text affected substitute operation. i'd appreciate alternative solutions well. you have use :help sub-replace-expression . in it, use submatch(2) instead of \2 . if expression custom function, can side effect store original length in variable, , access later: function! replace() let g:replacelength = strlen(submatch(0)) " equivalent of \2\rreplace return submatch(2) .
