the 2 apps have same shareduserid. when use code in app1 context.openfileoutput("/data/data/org.me.app2/files/shared-data.dat", mode_private) i exception telling me file contains path separator. i trying write file app1 app2's storage. (i of course need make sure app2's files directory exists first) ideally, write user specific directory instead of app specific directory, not know if can done first of all, never use full path internal storage /data/data . let operating system give path (for example, via context.getfilesdir() or environment.getexternalstoragestate() ). don't make assumption on data is. secondly - doing that! unlike file , context.openfileoutput prepends /data/data/[package] path, don't need specify that. specify file name. if feel it's safe , necessary, , if both apps share same user id using android:shareduserid in manifest, can context of other app using context.createpackagecontext() , use context_restricted,

trips hasmany legs airports has no associations how can find cheapest trip each destination airport using cakephp? right now, thing can think of foreach through array of airports. require hundreds of queries database (which think not fastest way of doing it). function getcheapesttrip($origin){ $airports=$this->airport->getairports(); foreach($airports $airport): $cheapest_flights=$this->trip->find('first', array( 'conditions'=>array('leg.origin'=>$origin, 'min(trip.price) price'), 'fields'=>array('trip.origin','price','leg.destination','leg.depart','leg.arrive'), 'recursive'=>2, )); endforeach; } } also, think data type stuff should in model per cakephp conventions (fat models, skinny controllers). read call different model's function such getairports can use loadmodel found in cakephp's controller method section. how should 1 model's data/m

i have created class inherits qlistwidget , meant stack of cards. i have overloaded drag , drop functions allow card dragged table (another object of program) , stumble on problem. the qlistwidget shows items (mainly because add them gui beginning). so how goes: in mainwindow initialise cardpile object , fill shuffled vector of cards. now want qlistwidget show 1 (but showing grid cards). on drop remove item qlistwidget. have no idea if add , remove 1 card @ time (so shows 1 card ofcourse) in code. public: tilestack(qwidget *parent = 0); void addcard(qpixmap pixmap, qpoint location); qpixmap showcard(); protected: void dragenterevent(qdragenterevent *event); void dragmoveevent(qdragmoveevent *event); void startdrag(qt::dropactions supportedactions); //in function remove current item these functions in cardpile : qlistwidget. so: void tilestack::startdrag(qt::dropactions /*supportedactions*/) { qlistwidgetitem *item = currentitem();

in resharper options menu under formatting style, displays code looks after formatting. these stored anywhere? i'm planning publish style settings shared location other developers on team can import settings. have document out there people can view before importing settings see code after formatting. is there online documentation somewhere shows defaults? or rather there way export (or parse if these snippets stored somewhere on disk) can format displayed without having go through each setting individually , copy/paste? you can use r# code style sharing this: anyhow don't know document shows r# defaults or tool map current settings code snippet or template. hope helps.

why css rules not cascade down automatically html controls input or select , style display of text in them? for ex: have css class applied on body tag renders text in red. due cascading rules, text in html document rendered in red (unless overridden). if have textbox control in document, style not cascade textbox render text in in red. could point me reference document talks that?? the reason default css styles determined browser. input , select have default colors/sizes/padding etc. most other elements use inherit color , size. another example font-size of table fixed , not inherited default, , must overridden developer. try example html: <html> <style type="text/css"> body { color:red; font-size:36px; } </style> <body> hello <input type="text" value="test value"/> <table><tr><td>cell value</td></tr></table> </body> </html> you see font-size ,

i'm migrating/consolidating multiple fmp6 databases single c# application backed sql server 2008. problem have how export data real database (sql server) can work on data quality , normalisation. significant, there number of repeating fields need normalised child tables. as see there few different options, of involve either connecting to fmp on odbc , using intermediate copy data across (either custom code or ms acess linked tables), or, exporting flat file format (csv no header or xml) , either use excel generate insert statements or write custom code load file. i'm leaning towards writing custom code migration (like this article does, in c# instead of perl) on odbc, i'm concerned overhead of writing migrator used once (as new system existing db's archived)... a few little joyful caveats: in version of fmp there's 1 table per file, , single column may have multi-value attributes, separated hex 1d, ascii group separator, of course! does have experience

how 1 enter special characters label in c# (windows forms)? if try write "&" label you'll sort of underscore instead.. so what's c# equivalent of "&"?

when create foreign key in table become duplicate index? in db2 z/os, if create table foreign key, not have define index on underlying column. an index not defined automatically when create table. if want one, can create 1 separately (via create index statement). think common define index includes foreign key column(s), not requirement. depends on how application accesses data. for overview on db2 keys, check out: http://publib.boulder.ibm.com/infocenter/zos/basics/index.jsp?topic=/com.ibm.db2z.doc.intro/db2z_keys.html .

i have 2 activities : - activity gathering data internet (it takes time) - activity b building ui elements based on data received (it takes time too) when activity start downloading, app enter loading phase. when it's complete, activity b starts, have transition between views of & b. b requires loading phase. i have loading - transition - loading - result doesn't nice @ all. i have loading - transition - result loadings of both activities grouped. so question : there way start activity delay transition ? i don't think going right way this. suggest having 1 activity loader. use asynctask load data in different thread. update ui data gets loaded , when done remove loader. should use multiple threads work takes time because otherwise ui freeze. looking @ said above, don't see why need 2 activities.

i'm developing new wordpress widget. configuration form in widgets admin panel includes category , subcategory dropdowns (these not wordpress categories). the values these dropdowns need retrieved via ajax, plus changing category dropdown should load new values subcategory dropdown via ajax. so, need use jquery target current dropdowns, , set handler change event. how can right jquery selector in wordpress achieve this? user may add several of these widgets sidebar, can't use generic id or css class. or there more reasonable way code this, maybe using wp_localize_script? there has unique factor amongst category dropdowns (since making selection there load options within subcategory). i use data() method attach unique identifier (whether id, or whatever) each of these pulldowns, attaching class each of pulldowns (mywidgetname-category, or whatever). then iterate on each of elements matches class, attaching change() event handler reads unique identifier attac

does know how check if key exists using membase client (enyim)? dont want pull entire object cache, check if in there. unfortunately there no "exists" operation in memcached, there hacks can do: do client.store(storemode.add, keytocheck, null, new date(2000, 1, 1)); add fails if item exists, , return false in case. you can client.append(keytocheck, new arraysegment<byte>(new byte[0])) return true if key exists, value not change. or client.cas(storemode.set, keytocheck, null, uint64.maxvalue) fail if item exists. please keep in mind 3 operations will create item if key not exist, need clean after them. also, if multiple threads checking same item, it's possible 1 thread treat threads temp item real one.

i'm experimenting full text search. have 50 million row table xml field, , set full text search on it. it's 2 days later now, , indexing still ongoing. looks it's not hung, , continuing index, very, slowly. based on fact when query table, more results time. also, looking @ full text index properties (right-click on table in sql server management studio) full text docs processed continues go up is normal, indxing slow? @ speed, it's not usable. see no errors in full text search log file. looking @ log file more - see apparently when created half million row table , put full text index on that, took 1 hour index. so, extrapolating that, take 100 hours index table. how can speed up? thanks input! sylvia with 50 million rows, reaching scale sql servers have other overhead , better existing text search engine uses inverted indexes. there various flavors of sharepoint search little money, or use open source search engine , move on there.

i'm experiencing documented bug webkit browsers render page incorrectly on first load because javascript executing before css has finished downloading (due them being downloaded in parallel). while quick refresh fixes of page, solution inadequate problem (i run command-line utilities take screenshots of our pages, these utilities don't have option "refresh" page before taking screenshot) does have suggestions or solutions ensuring css-include loaded in it's entirety before javascript-include , inline-javascript executed? thanks! -dan edit -- not using library. 'ol javascript. if using library think of them allow this. it's easy jquery, if not can use <script defer="(x number of second)">function()</script> @ end of hte page. may consider moving javascripts bottom of page possible. js best practices.

while learning haskell took side road (so speak) in researching kent recursive calculator , sasl functional languages. struck similarities between them , haskell , since predate wonder if/how provided influence. any information regarding influence (or lack thereof) of krc , sasl on haskell appreciated. the connection you're looking here david turner , largely responsible sasl , krc, involved miranda , non-strict, purely functional language. miranda relatively popular in time, proprietary language; open standard alternative miranda major motivation creation of haskell. for further details, see a history of haskell: being lazy class , hudak, hughes, spj, , wadler, mentions turner's work other influences on haskell.

i have simple website calculates grades of college students. there different subjects each department. each department has 42 subjects. thinking of providing username/password authentication users don't have input grades each subject every time. not want users register on site filling sign form. want them log in via face book account. thinking can't figure out how can this. have developed site in codeigniter. i looked same solution, here blog post it: http://blog.biernacki.ca/2010/11/a3m-a-codeigniter-account-authentication-authorization-module-installation/ a3m codeigniter pretty @ doing want, plus offers other openid providers (other facebook)

ok, pretty pretty pretty new wpf , xaml, despite search not find simple solution , seems me won't able find answer pretty soon. the question simple, have created wpf project , have datagrid in selectlist.xaml once row selected, save selected row in object object called "category". far ok can't figure out how going obtain reference object other place temp.xaml ? thanks highly appreciated cheers a common way provide indirect communication in wpf leverage mediator pattern. can use mediator publish selection of category, , have temp view subscribe notification of change in selection of category. see http://www.eggheadcafe.com/tutorials/aspnet/ec832ac7-6e4c-4ea8-81ab-7374d3da3425/wpf-and-the-model-view-vi.aspx simple example of concrete mediator. there several popular mvvm frameworks available provide mediator pattern implementations if want more robust implementation. simple mediator implementation: public sealed class mediator { private static

i made simple script hide/show hidden div. page automatically adjusts height on firefox, safari , chrome. however on internet explorer 7, div overlaps contents @ bottom i'm using joomla cms. have gone wrong ? have tried including "position:relative" bottom contents isn't helping. $j(idname).css({"opacity": "0"}); $j(idname).slidetoggle('fast', function() { $j(idname).animate({opacity:"1"}, function() { if(jquery.browser.msie) { this.style.removeattribute('filter'); $j("#main-body").css("height","auto"); } }); }); visit http://educationtechnologysummit.com/sponsors-a-partners.html clearer view i'm bit unclear question, looks of it, think problem presenting when mouseover menu item in ie7 menu div hidden behind other elements.

my domain object doesn't use 2 non-nullable columns table in database. both of columns guids. there way can supply default value these columns in mapping file i'm able save domain object database? you have few options: provide own <sql-insert> in hbm.xml file. unfortunately forces take control of insert logic. map columns private fields within object aren't exposed , set guids when create new instance. nhibernate can save these fields when inserting. can mark mappings update="false" they're ever inserted. add default values columns in database schema.

i've done profiling , seems of time spent during drawbitmap, called (understandingly) on every frame. i use surfaceview/updating thread/canvas locking approach demonstrated in lunarlander sample. i've changed (according this question ) on first frame construct bitmap buffer , paint onto it paint each subsequent frame reusing bitmap (not on screen changes) at end of each frame paint buffer once target canvas (to screen) traceview showed me drawbitmap takes 5ms each frame on 800x480 device. can better or 'carved stone' , have optimize other parts of code achieve frames per second? it depends on many things, drawbitmap() fast can get. in particular case, if don't need blending, make sure using opaque bitmap. in addition, try use bitmap in format compatible surface. instance, if using 16 bits surface, drawing 16-bits (rgb565) bitmap fast (it's memcpy call.) if surface 32 bits, use argb8888 opaque bitmap.

i need call function on timer (lets onticktack() function) , reload info in asp.net mvc project. know there several ways that, 1 best opinion? note: function should called 1 place only, , should called every x mins till application up. edit 1: reload info - example have in cache , want update db on timer - once day in time. the answer question depend on mean reload info in asp.net mvc project . not stated problem , such, more obviously, cannot have stated answer. so if assume want periodically poll controller action , update information on view use setinterval javascript function periodically poll server sending ajax request , update ui: window.setinterval(function() { // send ajax request every 5s poll changes , update ui // example jquery: $.get('/foo', function(result) { // todo: use results returned controller action // update ui }); }, 5000); if on other hand mean executing task on server @ regular periods use regist

how can have make auto redirecting every user goes mysite.com/ mysite.com/features? thanks set root route direct folks there (these rails 3 routes): in config/routes.rb root "content#features" in app/controllers/contents_controller.rb class contentscontroller < applicationcontroller def features end end that won't redirect, however. that, you'll need this: in config/routes.rb match "features" => "contents#features", :as => "features" root "content#index" in app/controllers/contents_controller.rb class contentscontroller < applicationcontroller def index redirect_to features_url end def features end end

given elevation map consisting of lat/lon/elevation pairs, fastest way find points above given elevation level (or better yet, the 2d concave hull)? i'm working on gis app need render overlay on top of map visually indicate regions of higher elevation; it's determining polygon/region has me stumped (for now). have simple array of lat/lon/elevation pairs (more specifically, gtopo30 dem files), i'm free transform data structure suggest. we've been pointed toward triangulated irregular networks (tins), i'm not sure how efficiently query data once we've generated tin. wouldn't surprised if our problem solved how 1 generate contour map, don't have experience it. suggestions awesome. it sounds you're attempting create polygonal representation of boundary of high land. if you're working raster data (sampled on rectangular grid), try this. think of grid assembly of right triangles. let's have 3x3 grid of points a b c d e f

i use fsockopen() connect multiple servers in loop. however servers not valid , php warnings 1 below: warning: fsockopen() [function.fsockopen]: php_network_getaddresses: getaddrinfo failed: requested name valid, no data of requested type found is there way prevent these warnings. like checking whether server before trying fsockopen it? or there or better solution this? use error control operator , check results of fsockopen() verfiy have valid connection. $rc = @fsockopen(...); if (is_resource($rc)) { // work }
