java beginner here. i made small java app in eclipse (on windows), using lwjgl lib , slick. when export executable .jar file, , run resulting .jar, doesn't anything. no errors, no nothing - doesn't seem run. following tutorial : http://www.cs.bsu.edu/homepages/pvg/misc/slick_eclipse_tutorial.php here's manifest.mf file looks : manifest-version: 1.0 main-class: simpletest class-path: lib/lwjgl.jar lib/slick.jar apps don't use lwjgl export fine. doing wrong ? i tried using jarsplice, didn't work, though might misusing it. pointers ? my best bet missed reference main-class in manifest -file. have @ this shows how set manifest -file correctly. have fun! edit: manifest-version: 1.0 main-class: simpletest class-path: lib/lwjgl.jar lib/slick.jar <-- new line without content --> edit 2: ok, able reproduce behavior. tried run exported jar via console i've got following exception: exception in thread "main" java.

i want search , replace first word in php follows: $str="nothing inside"; replace 'nothing' 'something' search , replace without using substr output should be: 'something inside' use preg_replace() limit of 1: preg_replace('/nothing/', 'something', $str, 1); replace regular expression /nothing/ whatever string want search for. since regular expressions evaluated left-to-right, match first instance.

i use on this. i'd overlay audio.mp3 file (or other format matter) onto video. i'm using free version of expression encoder 4, , video outputs wmv. thing is, don't know how add audio file video mediaitem. tried this, didn't add audio on result: mediaitem videotrack = new mediaitem(@"path\to\videofile.wmv"); videotrack.outputformat = new windowsmediaoutputformat(); videotrack.outputformat.videoprofile = new advancedvc1videoprofile(); mediaitem audiotrack = new mediaitem(@"path\to\audio.mp3"); videotrack.outputformat.audioprofile = audiotrack.sourceaudioprofile; job.mediaitems.add(videotrack); job.encode(); and when didn't work (perhaps because profile alone metadata, , not audio file itself), tried overlay audio way overlay image onto video, doing this: mediaitem videotrack = new mediaitem(@"path\to\videofile.wmv"); string overlayfilename = @"path\to\audio.mp3"; videotrack.overlayfilename = overlayfilename; job.medi

i have string $eventdays holds information regarding days selected. the format of data is: monday = mo tuesday = tu wedneday = thursday = th friday = fr saturday = sa sunday = su mo,tu,we,th,fr,sa,su so if example tuesday , friday selected, string be: tu,fr if monday, wednesday, , saturday selected be: mo,we,sa note: combination of days can selected. i wondering how information, , preselect checkboxes. checkboxes are: <input type="checkbox" name="days[]" value="mo" />monday<br /> <input type="checkbox" name="days[]" value="tu" />tuesday<br /> <input type="checkbox" name="days[]" value="we" />wednesday<br /> <input type="checkbox" name="days[]" value="th" />thursday<br /> <input type="checkbox" name="days[]" value="fr" />friday<br /> <input type="c

this may winforms newb mistake, i've created user control has 1 component on - telerik dropdownlist control. when drop on form looks correct. however, run form control stretches off form. the dropdownlist on user control has anchor property set top/left/right/bottom. before: after: what heck doing wrong here? edit: bit more info: if close designer , open up, changes sizes. code doesn't appear cause problem. in fact, commented out of code (besides initializecomponent() call) , still see problem. control still works - when run form populated data i'm expecting. it's stretched. i can "work around" issue setting width of dropdownlist 35 pixels less size want be, when resizes it's correct width, shouldn't have to. you on right track. looks though anchoring way off page. try removing anchor right starters see effect has. if doesn't work, perhaps try different combinations of anchoring see effect has on control. make sure

i'm having strange issue 2 slidetoggles. #bannerchoice slide works fine, #search slide, should, when open, overlap #bannerchoice, never opens more partway. instead, forces page reload. here's code: function bannerchoice() { $('#bannerchoice').slidetoggle(function() { if($('#bannerchoice').is(':visible')) { $('html').css({overflow:"hidden",height:"100%"}); } else { $('html').css({overflow:"auto",height:"2171px"}); } }); } function toggleform() { $('#search').slidetoggle(350); return false; } and <div id="bannerchoice"> <div id="bctext">select banner graphic:<br/></div> <div id="bcimages"> <form action="#" method="post"> <input type="hidden" name="setbanner&quo

this has driven me bananas. it's simple , easy , yet can't figure out what's wrong it. i want checkbox value populated in controller (for testing purposes). here form. <a href='#' name='submitform'>submit form</a> //i have jquery attached tag , submit form when user clicks echo form_open('test/show'); echo form_checkbox('checkbox[]','value1'); echo form_checkbox('checkbox[]','value2'); echo form_checkbox('checkbox[]','value3'); echo form_checkbox('checkbox[]','value4'); echo "<input type='text' name='text1' value='ddd'>"; echo form_close(); //my controller test public function show(){ $data1=$this->input->post('text1'); //i can text1 value input box $data2=$this->input->post('checkbox'); //it keeps giving me undefined index 'checkbox' $data3=$_post['checkbox']; //sam

my list: list = ['name1', 'option1.1 value1.1', 'option1.2 value1.2', 'name2', 'option2.1 value2.1', 'option2.2 value2.2', 'option2.3 value2.3'] and want create dictionary this: dict = {'name1':{'option1.1':'value1.1', 'option1.2':'value1.2'}, 'name2':{'option2.1': 'value2.1', 'option2.2':'value2.2', 'option2.3':'value2.3'} i don't know how big list (numbers of names, options , values). idea? with list , dict comprehension: id=[b[0] b in enumerate(lst) if 'name' in b[1]]+[none] d={lst[id[i]]:dict(map(str.split,lst[id[i]+1:id[i+1]])) in range(len(id)-1)} your original list here named lst this perhaps not readable answer @sr22222 , perhaps it's faster, , matter of taste.

this question has answer here: doing calculations in mysql vs php 5 answers are there performance concerns of note when using mysql's concat() function in select query? faster/slower/negligible simple select, , format strings view using php after result set database returned? or more complicated sql query multiple calls concat() returns string formatted view better approach? ie this: select concat(lastname, ', ', firstname) people; faster/slower/no difference this: <?php $query = 'select lastname, firstname people'; ... $name = $data['lastname'] . ', ' . $data['firstname']; //or $name = sprintf("%s, %s", $data['lastname'], $data['firstname']); ?> you're better off in cases doing filtering , data massaging sql engine versus on web server.

i have used reflection.emit dynamically generate types , methods. works fine, want include descriptive information method others can use more easily. normall including above method: /// <summary> /// descriptive information /// </summary> /// <param name="paramname1">paramname1 description</param> /// <param name="paramname2">paramname2 description</param> /// <param name="gltypefieldreference"></param> /// <returns>information return type</returns> is possible include information reflection.emit, , if so, how? no, because not part of il metadata. instead, compiler writes optional .xml file goes alongside dll, , typebuilder etc doesn't handle in way. of course write xml file separately - schema should available somewhere.

i writing chrome extention need store , restore user's highlighted selection. stored information stored on server. wondering how this? i looked using range, unsure if right way since example below worked in firefox. i found example works in firefox :( i think technique on page work in chrome: there's no reason why shouldn't. when save selection , reload, see selection restore , disappear, suspect in page (possibly ads) destroying selection somehow. if can't work, try serializer module of rangy library, although it's overkill chrome. in general, using browser's selection , range apis way go. standardized , universally supported (with quirks , bugs, naturally) in current browsers.

i developing application presents different stories kids. these stories made ​​in flash. problem how add storys app. initially 1 of approaches create app in coco2d , make animations in language (converting animations in pictures). due possess many animations , sounds, process complicated thus, asked opinions on approach should solve problem. opinion help. thanks... if want change way solve problem, can try adore air let use flash on ios apps : an example on how this if want continue cocos2d, can find tutorials there project : good tutorials make project cocos2d if stories doesn't have interactive elements, can try convert stories in flash video files softwares (try enter in google).

why should use event tracing windows (etw) on standard .net eventlog class , , vice versa? knowing we'll using quite few performance counters impact decision? what know far: etw should perform better . etw more work integrate (e.g. .net event tracing windows ) by selecting 1 of standard channels in etw (e.g. application, system), same information available in event log. etw has many advantages. first, in .net 4.5, far simpler use. eventsource class in 4.5 dramatically simplifies creating events within code. however, without this, etw has huge advantages, though typically work differently, and, such, serve different purpose eventlog. eventlog designed logging. etw, on other hand, allows trace application's progress in context of system whole . when start collecting etw events, collect them on system basis, lets not trace application, see what's happening in relation system it's running. using tool perfview , can see how specific portions of

my current usage of git described "commit , often". attempt make each commit single logical unit (as discussed in good commit criteria ). however, i'm iterating design , wish save each stage. if come ugly functional, want commit checkpoint before cleaning things up. what experience in matter - has caused issues team? going beyond ugly code - acceptable locally commit broken code long don't push until bugs fixed? the common convention use feature branch (or set of branches) live in repository - , perhaps somewhere online github or gitorious. you can rebase , rewrite feature branch reasonable impunity until have ready submit upstream in whatever project-specific way want. allows build, , share, work-in-progress code without headache. along way, building series of commits, using interactive rebase (or other rewriting tools) turn set of clean, logical commits great way move checkpoints in time checkpoints in functionality - , works best if commit extre
