i have 2 multiselects in itemselector , in formpanel . each multiselect composed of 2 stores : left side, , right side (with arrows move items between 2). when load panel, feed reference, in order highlight items moved 1 side other (e.g. set style red moved items) because today there no way differentiate them. i managed catch event afteradd on stores , apply style through dom access. works during trace, later on remaining extjs standard calls performed, overriding style applied... i feel i'm doing not way, i'm new extjs i'm bit lost here... ! edit : here sample of code, forgot tell worked on extjs 3.2 (hum...). pool_cnx_to_rule formpanel : pool_cnx_to_rule.aftermethod('add', function () { //var pools_available_ = ext.getcmp('pools_available').getvalue(); var pools_selected_ = ext.getcmp('pools_selected').getvalue(); var i, j; (i = 0; < pool_cnx_to_rule.data.length; ++i) { var pool_descr_ = pool_cnx_

i'm writing test webapp. @ 1 point in application webpage completed using javascript. testing i'm using visual studio 2012 nunit , selenium . want check if box id=j_idt13:jnumber has text value of sometext . ijavascriptexecutor js = driver ijavascriptexecutor; string valoare = (string)js.executescript("return $('#j_idt13\\:jnumber').val();"); assert.istrue(valoare.equals("sometext")); i keep getting error: "syntax error, unrecognized expression: unsupported pseudo:jnumber". what missing here? i know have works i'd caution avoid using javascript fetch value of element, in fact in general should avoided when doing tests except when there no other way want do. reason selenium supposed behave typical user would. typical users don't type javascript page or interact directly. goes using jquery tests should not assume jquery exists on page , functioning. selenium provides ability fetch values of fields i'd re

i've got webview in titanium app returns empty string when ask check typeof variable. point of exercise figuring out if function exists on page reloads in different forms. var hasauth = self.registerview.evaljs("typeof authenticate;") this works fine in ios, , in fact in android works on many occasions well. yet on android, return nothingness, represented 'undefined.' ps: no, problem not including 'return' in javascript string. titanium , causes errors if too. the solution in case turns out be: var hasauth = self.registerview.evaljs("'' + typeof authenticate;") somehow evaljs can typeof work, not if line starts typeof.

i've been trying past few days put simple collision simple game. i've looked in lots of places on internet haven't found helpful. i'm using bounding boxes , want player box stop when hits block of 4 sides (and not stuck or bounce against block). doesn't sound difficult i've found incredibly difficult. wanna know code need put in if statement's brackets, i've read , heard theory can take. please if can. if(bb_collide(player,block)){ //detection works fine, //just not sure afterwards } else{ player.setx((player.getx() + velx)); player.sety((player.gety() - vely)); player.set_coll(player.getx(),player.gety(),player.getwidth(),player.getheight()); block.set_coll(block.getx(),block.gety(),block.getwidth(),block.getheight()); } i figured out, having couple of bad days, sorry if had bad attitude or got wanted to. heres did if anyone's interested because works 1

i wondering if possible add newly created diagram component on palette. i adding components on diagram programmatically (with wizard ask user variables add in/on component). , give user possibility make similar component dragging , dropping palette. (say created component "wheel" variables, nice able create 4 of them without having use wizard every time)

i trying see if performance of both can compared based on objective functions work on? hierarchical : single linkage, complete linkage , average linkage algorithms non hierarchical : fuzzy c means , k means don't confuse algorithms , tasks . there more 1 algorithm k-means. there @ least 2 dozen. use k-d-trees acceleration, example. , heuristics, because finding optimal k-means solution shown np-hard in general, believe. similarly, there naive o(n^3) runtime , o(n^2) memory approach hierarchical clustering, , there algorithms such slink single-linkage hierarchical clustering , clink complete-linkage hierarchical clustering run in o(n^2) time , o(n) memory. last not least, if use dbscan , set minpts=2 , result same single-link hierarchical clustering when cut @ height of epsilon . yet, appropriate index, dbscan runs in o(n log n) (e.g. in elki - scipy implementation not clever, needs o(n^2) memory , runtime). so why can have such different runtimes

i made program search .txt files. if click file means "open with" dialog box should appear, , dialog box contain list of installed programs. i using code searching through files: public file[] finder( string dirname) { // create file object on directory. file dir = new file(dirname); // return list of files in directory. return dir.listfiles(new filenamefilter(); } public boolean accept(file dir, string filename) { return filename.endswith(".txt"); } what java code can use make "open with" dialog box appear? you should use filechooser this. take here : //create file chooser final jfilechooser fc = new jfilechooser(); ... //in response button click: int returnval = fc.showopendialog(acomponent); public void actionperformed(actionevent e) { //handle open button action. if (e.getsource() == openbutton) { int returnval = fc.showopendialog(filechooserdemo.this); i

i'm creating application stores data users. wondering mapping of gender appropriate: male - false; female - true or female - false; male - true is there standard this? i have seen bit (sql server) type being used genders, mentioned. places i've worked used char(1) column that, because thought someday might have store genders other male , female (i.e.: androginous/assexual, transexual (both male or female), hermaphrodite, unknown etc.). , knows? in case, both solutions work. i'm inclined bit solution may have better performance if scalability issue, though should matter huge databases.

i have edittext users normaly enter numbers. therefore i'm using inputtype.type_class_number numerical soft keyboard. occationally though, users may want enter letters, have button switches between inputtype.type_class_number , inputtype.type_class_text. works fine, found behaviour becomes strange on devices hardware keyboard. found this answer solves issue, can exclude keyboard switching functionality devices. but there devices, e.g. asus transformer prime tablet, never changes software keyboard layout when switching between inputtype.type_class_number , inputtype.type_class_text. how can know if software keyboard change layout or not? how can know if software keyboard change layout or not? you can't. inputtype hint, not demand. input method editors ("software keyboards") don't have buttons (see graffiti). there no means of interrogating system determine capability of input method editors, largely because authors of input method editors

i getting problem in finding tables related 1 table in same or different db. thanks smruti. relations between tables can defined in foreign keys. without these, 2 tables can not connected implicitly. things udfs in check constraints not count: opaque. foreign keys exist in same database too. there should no related tables in database anyway: if have, can never transactionally consistent , can never relied upon have same data. in sql server 2005+ can use this msdn article explain how works. there no single answer or query use.

i want multiply high precision integer (long or biginteger) small double (think > 0 , < 1) , arithmetically rounded integer (long or biginteger) of exact arithmetic value of operation result. converting double integer not work, because fractional value gets lost. converting integer double, multiply , converting result integer not work either, because double not precise enough. of course argue, because double operand not precise enough in first place, might not matter result not precise same order of magnitude, in case, does. bonus question: using bigdecimal works, seems inefficient. converting long double , multiplying , converting seems run 500 times faster (albeit losing precision) converting bigdecimal. there more efficient possibility? possible gain performance when multiplying several different long each same double? you want use bigdecimal in order preserve precision. biginteger mybi = new biginteger("99999999999999999"); double d = 0.123;

i started opencl , want port app have in cuda. problem i'm facing kernel stuff. in cuda have kernel functions in same file, on contrary, opencl asks read file kernel source code , other stuff. my question is: can have 1 single file kernel functions , build program in opencl or have have 1 file each of kernel functions? it nice if give little example. the difference between opencl , cuda (in specific regard) cuda allows mix device host code in same source file, while opencl requires load program source external string , compile @ runtime. but nevertheless absolutely no problem put many kernel functions single opencl program, or single opencl program source string. kernels (say c api kernel objects) extracted program object using respective function names. pseudocode simplifying opencl's ugly c interface: single opencl file: __kernel void a(...) {} __kernel void b(...) {} c file: source = read_cl_file(); program = clcreateprogramwithsource(source); c

what doing 'checkout' (if new) or 'update' website code subversion. compile code, proceeds if compiled , ftp compiled location website hosted replacing existing code. done in final builder 7. my question how put changed files (last commit on subversion) on ftp location after successful build , compiled in fb7, , files should published? sounds if need keep cache of files previous build, , check , compare each of them using "file compare" action. but motivation behind it? replace whole build output. attempting segmental updates inevitably lead not being copied or updated.

i'm newbie servicestack , learn how works, i'll develop web api northwind database (using repository pattern). i've checked sample project servicestack.northwind , there 2 services (customers , orders). i'd develop complete api (customers, orders, products, etc..). matt cowan has done . basically, services same operation: receive request. execute (repository.get, repository.add, repository.update, repository.delete). send response. for this, thought making base class work. first started like: public class baseservice<trepository, tentity, tdto> : service { ... } the problem of class don't know types request , response each operation. thought i'd pass them type arguments: public class baseservice<trepository, tentity, tdto, trequest, tsingleresponse, tcollectionresponse> : service { ... } i don't this. i'm sure can done without passing n type arguments class. how approach development of base class?. thank

i have data days of week , want find data recent working day i.e dayofweek != 1 , dayofweek != 7 my clumsy case along lines of where case when dayofweek(curdate()) = 1 day(time) = date_sub(day(time), interval 2 day) when dayofweek(curdate()) = 7 day(time) = date_sub(day(time), interval 1 day) when dayofweek(curdate()) != 7 , dayofweek(curdate()) != 1 day(time) = day(curdate()) else 1 = 1 end this code, day(time) = date_sub(day(time), interval 2 day) never matches, because day(time) never ever equals day(time) - 1 day . same saying x=x-1 in algebra... can not true. suspect mean this: where case when dayofweek(curdate()) = 1 date(time) = date(date_sub(curdate(), interval 2 day)) ... ... ... part left exercise asker. the date() function removes time part, can compare day. the date_sub() function needs subtract curdate() recent workday. in code subtracting datetime stored in table.
