(i dont see reason throw) please help. it case of code has evolved on time , no 1 cared clean up, or implementers of imageio relied on contract of serviceregistry , rather implementation details of it. in current implementation of imageio , serviceregistry don't see how ever happen. the thing can see it, potentially change implementation of iioregistry or serviceregistry lazy loading of categories example, or perhaps flush...

the goal have connected clients belonging one user running on array of different platforms able share common dataset. server gnu/linux. platforms , devices targeted include: gnu/linux, android , windows on x86_64, i686, armv7, armv8. possible consideration given osx , ios devices. ui toolkit qt5. non-interface logic in c++. code licensed under gpl or agpl. many applications google's maps, instance, require reliable connection work effectively. design decision each client should functional without network connection, assuming user has not used different device/platform change data. in such cases, synchronization network access should necessary. some applications written hand-rolled data persistence , synchronization layers customized each platform or subset of platforms. while quite effective, beyond available skill , manpower available (just me :) ). also, though i'm conditioned past experience think of things relational database perspective, data i'm expecting b...

i have foreach loop loops through present html , store data data file. issue (which has been raised before) last alliteration of foreach loop duplicated . using unset not work , writes data file within foreach loop! how can fix issue? want cut out duplicate , maintain writing data file... my code: // save data dat file $datafile = "datfile.dat"; $fh = fopen($datafile, 'w') or die("can't open file"); foreach($xml->drop $shipment) { $connote_id = $shipment->header->bill_of_lading; // 20 chars $output = sprintf("%-20.20s", $connote_id); echo $output; unset($shipment); fwrite($fh, $output); } $output .= "%%eof"; fwrite($fh, $output); echo "%%eof"; fclose($fh); xml: <?xml version="1.0" encoding="utf-8"?> <ishpmnt1> <drop> <header> <bill_of_lading>vw038687030000006</bill_of_lading> </header> </drop> </ishpmnt1> ...

i have several cases gridview within dialogfragment needs contextual menu. project supports api 8+, i'm using appcompat support library. far i've tried calling activity.startsupportactionmode() on underlying actionbaractivity, starts contextual actionbar/actionmode underneath dialog. i'm looking alternative common-but-hacky (and high-overhead) method of using activity themed dialog . poking around in source both framework , appcompat support library, get: for api 11+ standard framework: dialog dialog; actionmode.callback actionmode; window window = dialog.getwindow(); view toplevel = window.getdecorview(); if (toplevel == null) { return; } toplevel.startactionmode (actionmode); for appcompat support library: window window = dialog.getwindow(); view toplevel = window.getdecorview(); if (toplevel == null) { return; } android.view.actionmode.callback frameworkactionmode = new callbackwrapper (context, supportactionmode); toplevel.startactionmode ...

i have 2 tables - source , destination. merge source destination using merge query (sql server 2008). my setup follows: each destination record has 3 fields (in real application there more 3, of course) - id, checksum , timestamp. each source record has 2 fields - id , checksum. a source record inserted destination if there no destination record same id. a destination record updated source record same id provided source record checksum not null. guaranteed if checksum not null different respective destination checksum. given. a destination record deleted if there no source record same id. this setup should lend quite merge statement semantics, yet unable implement it. my poor attempt documented in sql fiddle what doing wrong? edit btw, not merge based solution here . create table #destination (id int,[checksum] int,[timestamp] datetime) create table #source (id int,[checksum] int) insert #destination values(1,1,'1/1/2001'),(2,2,'2/2/2002...

i have small tidbit of code webserver on arduino connected ethernet shield: client.println("<html><head><title>arduserv</title></head><body>"); client.print("current temperature: ");client.println(gettmp()); client.println("<form method=get>input:<input type=text size=25 name=inp><input type=submit value=submit></form>"); client.println("</body></html>"); is there way can update temperature using javascript don't have redraw page every second? can change temperature? i not use arduino http server couple of reasons. performance - micro controller, have limited resources. serving of headers , content can expensive if want interaction real time. manageability - i'm sure you're aware, it's frustrating having manage source of web page through strings in double quotes on multiple lines that. the solution i've found effective way make...

i'm (new ko!) playing view constructor offered ryan niemayer here: how structure knockoutjs application , , i'm trying set default view show on load… for example in #3, can use constructor function like… and here fork attempting set default: // (templates defined in fiddle) var view = function(title, templatename, data) { this.title = title; this.templatename = templatename; this.data = data; }; var definedviews = ko.observablearray([ new view("one", "onetmpl", new submodela()), new view("two", "twotmpl", new submodelb()) ]); var viewmodel = { views: definedviews, defaultview: 0, selectedview: ko.observable( definedviews[0] ) }; ko.applybindings(viewmodel); index.html: <!-- ko with: selectedview --> <div data-bind="template: { name: templatename, data: data }"></div> <!-- /ko --> http://jsfiddle.net/memelab/wvvym/2/ on load, selectedview ...
