i want bind data xml file? how can i'm using layout xml file define scrollview ?? if i've understood question right, want read layout file , insert scrollview. you want take layoutinflater task. example doing activity. layoutinflater inflater = (layoutinflater)context.getsystemservice(context.layout_inflater_service); scrollview sv = findviewbyid(r.id.id_of_scrollview); inflater.inflate(r.layout.id_of_layoutfile_to_include, sv); edit: after having read comment realise misunderstood question. scrollview not view want binding data, scrollview specialized framelayout, , therefore allows 1 child. your looking view listview (which adds scrolling automatically) another solution use layout in scrollview , dynamically (from code) add views. linearlayout ll = findviewbyid(r.id.id_of_linearlayout); //loop data , build view each data entry , add ll.addview(yourview);

i want kill thread when bad happen. what's suggestion thread suicide? you should never "kill" thread. main program, can abort using thread.abort method, not recommended, , unnecessary. your thread should nothing more method executing long loop. if "really bad" happens, return method , thread end. this enough such loop: private void mythreadloop() { try { while (somecondition) { // lengthy operation } } catch (exception ex) { log.error("something bad happened: ", ex); } } public void start() { thread t = new thread(mythreadloop); t.start() } on other hand, if need main program kill thread (but not "suicide" named it), should signal thread want end, , not abort without knowing going on in background.

are jquery events blocking? for example calling following method return immediately? $("body").trigger("myeventname", myvalue); my testing seems suggest are. if correct mean can return values custom events? var myresult = $("body").trigger("myeventname", myvalue); clearly doesnt work returns jquery object. can values returned? you can use .triggerhandler() method this, returns whatever last event handler event on selector returns (instead of jquery object chaining), use this: var myresult = $("body").triggerhandler("myeventname", myvalue); you can give try here . check out documentation page list of differences .trigger() .

i interested in knowing if possible. one example variable exists. foo = 1; var bar = 'foo'; if('foo' == 1)? is there way that. is there way bar == foo.variablename yes can wouldn't recommend it. s="unicorn" eval("var " + s + " = 'test'") alert(unicorn) but text in question kind of sounds want check if variable exists , possible if (typeof variable == "undefined") alert("it's not defined!");

i'm reading sources android, , read this: outputstream thumbout = mcr.openoutputstream(uri); bitmap.compress(bitmap.compressformat.jpeg, 85, thumbout); thumbout.close(); when trying store bitmap (bitmap) in database (uri uri of row in database). far can understand, openoutputstream allows store binary data in database, path of file placed in db. file placed somewhere in filesystem. correct? question is: how specify exact location of files when stored way? clarification. i suppose correct answer question used path 1 inserted in database.

i have occurence building maven archetype want #set( $controllerpackage = ${package}\.${artifactid}) i.e. set controllerpackage variable equal result of string concatentaion of following 3 elements ($package,'.',$artifactid) however obvioulsy not correct syntax - lexical error: org.apache.velocity.runtime.parser.tokenmgrerror: lexical error @ line 4, column 40. encountered: "." (46), after : "\" is there way can include period in outputted string? to construct string, use quotes. #set( $controllerpackage = "${package}.${artifactid}" )

i have below code, it running output in console is instant: true instant2: false as variable not being overwritten in global scope. how can access variable in global scope? var instant = false; $('document').ready(function(){ chrome.extension.sendrequest({ action: "getstorage", key: "instant" }, function(response) { instant = true; console.log('instant: ', instant); }); console.log('instant2: ', instant); }); it getting overridden, later. function(response) isn't getting executed until after outer function returns.

i have lot of paired fields (hoursdistance1, cityname1, hoursdistance2, cityname2, hoursdistance3, cityname3, etc.). what query need search lucene scores based on both fields having correct terms instead of 1 of them? i.e. if search city 3 hours here name, how return results hoursdistancen 3 hours here , citynamen without scoring other pairs of fields? you create document each pair. instead of id | hours1 | name1 | hours2 | name2 | ... you have: id | pair_num = 1 | hours | name id | pair_num = 2 | hours | name ... since want search 1 pair @ time, shouldn't need merge results or anything.

one viewcontroller shared 2 xibs, i.e. there 1 xib horizontal layout , 1 vertical layout. both xibs linked same viewcontroller, i.e.: hiscoreviewcontroller.h hiscoreviewcontroller.m hiscoreviewcontroller-horizontal.xib hiscoreviewcontroller-vertical.xib the question how can (re)load corresponding xib in didrotatefrominterfaceorientation ? thanks! you can use different views in 1 view controller. can change views based on orientation.

i have scroll view lots of image buttons. want change image image button when it's pressed. thing want image remain until image button pressed. that's why couldn't use selector. best practice achieve his? best regards you want this. imagebutton demo_button = (imagebutton)findviewbyid(r.id.firstimage); // when click demo button demo_button.setonclicklistener(new onclicklistener() { public void onclick(view v) { demo_button.setimageresource(r.drawable.secondimage); } } try this.

i using windows forms application in c# have label having date text 16-12-2010 want display different tooltip when mouse on date/month/year e.g. when cursor on date : today's date tooltip updated: one source of example when vote close question in stackoverflow.com use multiple labels - 1 each part. otherwise you're going need know characters in label mouse on - different font's render differently. that's can-o-worms if ever there one.

i can't make sense of following behavior: 1 header basic types, , header in use these types in several functions. afterward started constructing classes based on defined types , functions. in function header if leave following signature: void whateverfunction(parameters) the linker points out there multiple definitions of whateverfunction. if change to: inline void whateverfunction(parameters) the linkage problem gone , compiles , links well. know concerning inline replaces every function call it's code other it's pretty dark, question is: how linker treats inline functions in c++? when function in header not inline, multiple definitions of function (e.g. in multiple translation units) violation of odr rules. inline functions default have external linkage. hence, consequence of odr rules (given below), such multiple definitions (e.g. in multiple translation units) okay: $3.2/5- "there can more 1 definition of class type (clause 9), enu...

seemingly similar questions: " finding closest number in array " (in java) , " find nearest match array of doubles " (actually geography problem). i have (sorted) array of doubles. given arbitrary number (which may or may not exact match 1 of array elements), how can return index of number closest match? for example, using following array: 1.8 2.4 2.7 3.1 4.5 querying 2.5 return index of 1, corresponding value of 2.4. bonus points detecting values lie outside of range of array elements. example, using array listed above, code may decide 4.6 in, 5.9 out. if want try part of question, specifics in hands. array.binarysearch , returns: the index of specified value in specified array, if value found. if value not found , value less 1 or more elements in array, negative number bitwise complement of index of first element larger value. if value not found , value greater of elements in array, negative number bitwise complement of (the index...

i have simple table/model in rails, vat_rates . administrators need able select one, , 1 of these default rate selected on html form when creating new related items items have vat_rate_id . have added boolean default column vat_rates table. what straight forward, , rails-like way ensure 1 vat_rate can default 1 @ time? i'm not bothered if there no defaults, there no more one. you add custom validation method this , return error if vat_rate selected default already. alternatively can add before_update or after_update callback this set other default values false on update.

let have got 2 byte variable: byte a= 255; byte b= 121; byte c= (byte) (a + b); console.writeline(c.tostring()); output:120 please explain me how adding values. know crossing size limit of byte don't know operation performs in such situation because not looking chopping result. thanks edit: sorry 120 answer. you overflowing byte storage of 255 starts 0. so: + b integer = 376 your code equivalent to: byte c = (byte)376; that's 1 of reasons why adding 2 bytes returns integer. casting byte should done @ own risk. if want store integer 376 bytes need array: byte[] buffer = bitconverter.getbytes(376); as can see resulting array contains 4 bytes necessary store 32 bit integer.

say i'm going subtract: 0000 0000 - (-1) that is: (two complement) 0000 0000 - 1111 1111 --------- = ???? ???? whats gonna happen, brain f***ing me right now, went fine before, think overflow thats screwing me up, can give clearance on please :)? take two's complement of subtrahend , add minuend. 0000 0000 - 1111 1111 ... 0000 0000 + 0000 0001 ----------- 0000 0001

i need create non-visual component, foocomponent , management controls of type bar resides in form. i have following constraints: the foocomponent can added forms. only 1 foocomponent per form allowed. foocomponent should register form closing event, , when fires , function on bar 's , sent e.cancel value based on returned values. #1 , #2 above should enforced on run-time design time. #3 event registration should made automatically , not foocomponent 's users. i searched google , msdn , read component , componentdesigner classes, didn't find rescue. what should do? (1) control component can added form, use foocomponent constructor passed form, , don't define default constructor. it's called like: foocomponent component = new foocomponent(this); where component created within form itself. not-defining default constructor, this: foocomponent component = new foocomponent(); will not compile. (2) expose foocomponent prop...
