what need action classes serializable? when , how happen, if @ all. as far can tell, doesn't need serializable, , mistake make actionsupport implement interface. here best reasoning have found on subject (taken here ): it's common in web frameworks use serializable objects couple or reasons, such being able preserve state across server restart , shipping objects around in cluster. with said, (imho) believe design mistake have actionsupport implement serializable. don't believe either of above apply action objects since short-lived. choice of making actions serializable should have been left developer , not "forced" framework.

i'm making first app here, use both gps , network (for when gps not available) update location. i'm testing how network location works alone, find takes bit of time retrieve real location, < 1500m accuracy. (i take google maps example) notice i'm off accuracy circle , takes while update, , when "a while" more 30 secs or minute. so question is, there way of forcing location update using network provider? if using mylocationoverlay think have no control on location update intervals. you can try implement own overlay item own undelying location update code can specify own values location update frequency. see overlay , locationmanager docs details.

i let user pick directory , save downloaded file (my app downloads file). know tools (for example, es file explorer) provide such intent-filters. see http://www.estrongs.com/en/support/developers.html . start activity result , selected folder result. also, know there no "select folder" intent standards (i can't use same intent other tools). know other tools support such functionality ? let user use tool, not es file manager. also, astro provide such intent filters? can't find info on page. (i think astro used file manager android) i've come across might potentially here: http://www.openintents.org/en/node/159 it has demo application showing how can interact third party applications file/directory picker. that said, have not tried yet. stumbled across question still looking other options. edit: actually, looks similar es file manager link. perhaps merely clone.

what algorithm creating "3d" cube in console , rotating (dice roll style)? creative answers appreciated. i don't know if qualifies "algorithm" you'd looking for, full 3d calculations. example code drawing cube wireframe (i'm using vector/matrix classes opentk, them xna or other library well) using system; using system.linq; using opentk; class cubes { static void main() { var resolution = 25; var points = in enumerable.range(1, 8) select new vector3(i / 4 % 2 * 2 - 1, / 2 % 2 * 2 - 1, % 2 * 2 - 1); var lines = in points b in points (a - b).length == 2 // adjacent points && a.x + a.y + a.z > b.x + b.y + b.z // select each pair once select new { a, b }; var t = 0f; while (true) { t += .1f; var projection = matrix4.createperspectivefieldofview(.8f, 1, .01f, 100f); v...

this seems basic task, after lot of searching , research, still haven't found clear answer. found gridview, not sure how you're supposed it. i've found several apps have ui elements similar need, example top buttons of android market. that can accomplished horizontal linearlayout contains set of buttons or imagebuttons. rest styling. see hello linear layout started.

i have hidden form field: <input type=hidden id=blah1 value=true /> i have abutton, when clicked do: $("#b1").bind("click", function(){ $("#blah1").attr("value", "false"); }); but when form value on server side, 'true'. am doing wrong? i did this: e.preventdefault(); $("#blah1").attr("value", "false"); alert( $("#blah1").attr("value") ); it alerted value 'false'. you did include ' name ' attribute in real code, no? <input type=hidden id=blah1 value=true name=blah1 /> this still doesn't explain why see "true" on server side. if did include "name" attribute on hidden field, please post server-side code. running code have posted here, once "name" attribute added, achieved expected "false" result.

i have firefox extension listens "http-on-modify-request" , inspects requests coming firefox. i'd able cancel request (say return fail code page) or modify uri of request can't seem it. nsihttpchannel object doesn't allow - instance delete httpchannel; or reseting empty request httpchannel = components.classes["@mozilla.org/xmlextras/xmlhttprequest;1"].createinstance(components.interfaces.nsixmlhttprequest); don't work (and can't modify uri). so how both intercept , modify http requests in firefox extension. delete httpchannel; deletes variable, sort of saying httpchannel = undefined; . request unchanged. similarly, second idea sets variable point @ new nsihttpchannel instance, old request still unchanged. to modify request, use properties , methods. see nsihttpchannel or nsichannel or nsirequest . say, can't modify uri might want cancel (see below) , replace new one. i'm not sure how imagine 1 of 3 pages...

in 1 of projects have models don't want use poco i.e. use ef generated classes , others want use pocos. when mix those, poco mapping doesn't work , exception system.invalidoperationexception unhandled user code message=mapping , metadata information not found entitytype 'xxxxx.xxxxx.xxxxx.xxxxx'. source=system.data.entity this message incorrect in connection string. however, after through inspection confirm there nothing wrong or generated poco classes. found that mapping poco entities not supported if mapping attributes applied custom data classes, including edmschemaattribute @ assembly level. in msdn article working poco entities . while simplest solution split project 2 parts , keep poco , non-poco separately, wanted see if there way around. looks there isn't way this.

i have 3 mysql tables ( food , apple , , orange ). i want delete rows from: apple(idapple, iduser, name) orange(idornge, iduser, name) when deleting row in food(iduser, name) using 1 trigger? here trigger far: create trigger `food_before_delete` after delete on `food` each row delete apple, orange apple.iduser=old.iduser , orange.iduser=old.iduser but won't compile. how can make trigger deletes 2 tables @ once? delete 2 tables @ once trigger: triggers used enforce data integrity in tables. can use triggers delete number of tables @ once. before initializing triggers change mysql delimiter operator temporarily because triggers use semicolon ; operator specify multiple sql commands within trigger. step 1 change delimiter: delimiter $$ step 2 create trigger: create trigger `blog_before_delete` after delete on `blog` each row begin delete blog_tags blogid = old.id; delete blog_comm...

i have found book states if want use function c standard library takes function pointer argument (for example qsort), function of want pass function pointer needs c function , therefore declared extern "c". e.g. extern "c" { int foo(void const* a, void const* b) {...} } ... qsort(some_array, some_num, some_size, &foo); i not surprised if wrong information, - i'm not sure, so: correct? a lot depends on whether you're interested in practical answer compiler you're using right now, or whether care theoretical answer covers possible conforming implementations of c++. in theory it's necessary. in reality, can without it. the real question whether compiler uses different calling convention calling global c++ function when calling c function. most compilers use same calling convention either way, call work without extern "c" declaration. the standard doesn't guarantee though, in theory there compiler used diffe...

i have map application using in-house map engine on android. i'm working on rotating map view rotates map based on phone's orientation using sensor service. works fine exception of dragging map when phone pointing other north. example, if phone facing west, dragging map still moves map south versus east expected. i'm assuming translating canvas 1 possible solution i'm not sure correct way this. here code i'm using rotate canvas: public void dispatchdraw(canvas canvas) { canvas.save(canvas.matrix_save_flag); // mheading orientation sensor canvas.rotate(-mheading, origin[x],origin[y]); mcanvas.delegate = canvas; super.dispatchdraw(mcanvas); canvas.restore(); } what best approach make dragging map consistent regardless of phones orientation? sensormanager has "remapcoordinates()" method it's not clear resolve problem. you can trivially delta x , delta y between 2 consecutive move events. correct these values ...

i'm sorry if question bit obvious, i'm new blazeds , can't seem find answer. i'm running java on blazeds server flex front-end. i'd able instantiate java class once, have flex use setters , getters play data in java class (in sense, treating remoteobject if instance of class). far i've read seems way blazeds works, every time call java method flex, calls java constructors again, resetting input setter methods. there way have server hold instance of java class between method calls? thanks! you seem have misunderstanding of how works. objects in flex client , objects on server independent. in normal circumstances, flash player/a flex app talks remote service using either webserice, httpservice, or remoteobject. remoteobject supports amf , flash remoting blazeds, livecycle data services, coldfusion, , ton of other server side software. when make remote calls server, request no different standard web page call. exists in "isolation" ,...
