recently upgraded embedded quartz.net scheduler 2.x @ point had give on giving 0 thread schedulers unique names , have problem (very rarely) object trying create instance of zt scheduler throws exception because object has instance of zt scheduler instantiated , since zt schedulers have default 'quartzscheduler' name throws exception... i tried checking scheduler count using myschedfactory.allschedulers.count after calling myschedfactory = new stdschedulerfactory(properties) stdschedulerfactory creates instance of zt scheduler it's instantiated , not when getscheduler() method called dead end... i not find other way of checking existing schedulers before instantiating stdschedulerfactory and, mentioned already, instantiated, creates instance of zt scheduler ended using while loop in catch block horrible solution i'm hoping knows better way of checking existing zt schedulers... try { //setting properties

i have following type of json want send java (i'm using jersey , default json parser comes with) { "something" : "1", "someotherthing" : "2" , ... } but instead of creating object these properties in java, have single hashmap (or whatever) allow me still have access key , value is such thing possible? i don't have code transformation, use jersey this @post @path("/purchase") @produces(mediatype.application_json) @consumes(mediatype.application_json) public statusresult purchase(userpurchaserequest upr) { } if put properties , someotherthing strings in userpurchaserequest object, come in fine, want have in 1 structure (because don't know how many values get, , need names well) yes, possible. still, depends on json java api using. example using jackson json can create hashmap json string this objectmapper obj = new objectmapper(); string json = pbj.writevalue(<hash

i trying increment element in list in c#, need thread safe, count not affected. i know can integers: interlocked.increment(ref sdmpobjectlist1count); but not work on list have following far: lock (padlock) { differencelist[diff[d].propertyname] = differencelist[diff[d].propertyname] + 1; } i know works, i'm not sure if there way this? as david heffernan said, concurrentdictionary should provider better performance. but, performance gain might negligible depending upon how multiple threads try access cache. using system; using system.collections.concurrent; using system.threading; namespace concurrentcollections { class program { static void main() { var cache = new concurrentdictionary<string, int>(); (int threadid = 0; threadid < 2; threadid++) { new thread( () => { while (true)

i using codewarrior 8.3 (ide version 5.9) program 56f8367 dsc. i using respected third party software, imagine know doing , don't want mess code much, playing around passing void * parameters , not totally familiar with. so have function: static void t_callback _transmit( void *pcontext, tx_data *ptxdescriptor) { context *plinkcontext = (context *)pcontext; ... } which being called through function pointer. when stop processor before function call, can see address pointed pcontext 0x1000, after cast here, address pointed plinkcontext 0x0800. this, causes problems because start writing , reading different part of memory. there weird going on byte addressing/alignment getting "shifted" on 1 bit. see going wrong, don't understand why or, more importantly, how solve problem. what should looking for? (editing add call per comment request) - although, i'm not sure how considering buried in structures , being called through function pointer.

i'm trying build force-directed layout, wherein connected nodes have own internal layout not recursive force-directed layout (which, believe, possible hierarchy layout). "inner" layout custom, but, illustration let's wanted nodes, internally, have partition layout. possible? my question twofold: can pull off having more 1 style of layout (for instance, bubble graph inside force-directed graph) in sensible way d3, or d3 wrong tool such thing, and can use d3 layouts each of these layouts, or have custom. in end, design changed, , no longer called odd scenario. being more familiar d3, though, think can answer. yes. can done. each layout own discrete object, own data on work, , can given own dom elements populate. creating 2 layouts shared same data , dom outputs work, if manage interaction between 2 (making sure 1 overrode changes other when desired). what know can sure manually manipulate anything d3 doing. @ 1 point during development, actual

to work out how time taken perform algorithm, in main method, not print time gets interleaved system.print. long starttime = system.currenttimemillis(); a1.print(2); long endtime = system.currenttimemillis(); system.err.print(endtime - starttime); and if class this: public class a{ public void print(int n){ for(int = 0; <=n; i++){ system.out.println(i) }} it prints 0 1 2 and in line amount of time supposed go through loop, won't, won't print this: 0 1 2 1 here last line or 1 millisecond taken algorithm. textbook says must use system.err. , figure out way prevent interleaving. you like system.seterr(system.out); so output in same stream. use 2 different streams that's why interleaving. for code be: long starttime = system.currenttimemillis(); system.seterr(system.out); a1.print(50); long endtime = system.currenttimemillis(); system.err.print(endtime - starttime);

i added code site have text sanitization: var re = /(<([^>]+)>)/gi; (i=0; < arguments.length; i++){ arguments[i].value=arguments[i].value.replace(re, ""); } but somehow people able use tag , still able post pics on website through text area. please let me know if have code wrong. ps: users getting away tags well. never trust input data. user can use curl or else , send http post request data in body want server. therefore have rule validate data @ server side before saving database. you can introduce client-side validation though improve user experience anyway have validate input @ server side when request received. update: i see tagged question php tag, if server-side application written in php, can use html purifier sanitize input data , avoid xss, etc. if use php framework have own wrapper html purifier. example yii framework has it.

i use cardlayout mvc , try understand, when should create panels used cardlayout. for example: a detailpanel view , edit details of dataitem shown, when select dataitem on listpanel. should create , show detailpanel when select dataitem, or should create detailpanel @ start of application , call load method, when select dataitem, , show detailpanel? currently i'm using cardlayout stack. add panel when need , remove when i'm done editing. try avoid replacing view components. initially, create of detailpanel possible , update component models in listselectionlistener . use cardlayout variable portion of each detailpanel . it's unlikely creating view have perceptible performance impact; profile see. if find constructing model introduces significant latency, consider swingworker , illustrated here , here .

during runtime of app need iterate through each xml file lies in root of jar. i know can access concrete file this inputstream in = this.getclass().getclassloader().getresourceasstream( "filename.xml" ); but how can receive list of files in root of jar? thanks try this . java: listing contents of resource directory the classloader.getresource() function can handy way load files in java. files can loaded folder or jar file on classpath. however, api disappointingly lacks way list files in directory. (no, getresources() not it.) utility function comes rescue!

hiho, im facing serious issues implementing horizontal virtualizingpanel right way. virtualization works far , items positiones @ right positions when scroll though items, items start overlapping(for me @ item 671090) , following items start creating gaps between each other. effect increases depending on horizontal offset. tried locate problem watching itemposition in debug intends be. different implementations found in internet have same problem. tried virtualizingtilepanel implementation provided dan crevier , staggeredpanel described in "sams wpf control development unleashed". both seem have same problem when add lot of items. steps reproduce: 1. download example http://blogs.msdn.com/b/dancre/archive/2006/02/16/implementing-a-virtualizingpanel-part-4-the-goods.aspx or sample code from http://www.informit.com/store/wpf-control-development-unleashed-building-advanced-9780672330339 add example 1000000 items virtualization. scroll through data problem starts
